ChangeDisplaySettingsEx Windows API

CowboyBob — 2012-01-19T18:28:28 -05.00

We have developed an industrial robotic application in which the monitors are physically rotated. I am trying to change the screen orientation to match and all of the machines with ATI Radeon HD video cards will not accept the ChangeDisplaySettingsEx in the Windows API. I have Googled this and it seems to be quite a common question, however, no one has answered as to why this can't be done with the Windows API.

We have tried iRotate on these machines and every one of them change the screen orientation with iRototate. So I know this can be done just need some one to point me in the right direction as to how.

Does ATI have its own API?

Mobility Radeon HD 3650, 11.12, external monitor no longer syncs

rburch05 — 2012-01-16T20:36:13 -05.00

Background:
Dell Studio 17 (1737)
ATI Technologies Inc RV635 [Mobility Radeon HD 3650]
64bit Gentoo Linux, kernel 3.1.6 (I'm happy to post in alternate OSes forum, but I think this problem transcends OS...)

I have been running this rig for over 2 years using the proprietary AMD Catalyst driver blob (fglrx). Everything has worked well, simultaneously driving the laptop LCD and an external LCD panel (vga) at 1920x1200@60. Until the recent catalyst update to 11.12... when

Observation:
I no longer can properly drive any external monitor at all. The laptop LCD still works fine, but my regular external LCD panel exhibits full screen vertical flicker at 1920x1200@60 as though the sync rate isn't right, yet the card and monitor both report 60. Other monitors act like there is no signal, or are similarly incapable of displaying a proper screen at any resolution.

The results are the same whether trying to set resolutions using AMD's amdcccle control panel, or using xrandr from Xorg (Catalyst has provided support for this for some time).

I can almost get something to "stick" on my regular panel at 1680x1050@60; that is the LCD panel seems to display at this resolution but it blanks out every 20-30 seconds and then reappears. Sometimes the blank outs are more frequent. At this res the LCD panel reports 1680x1050@60.2 while amdcccle (or xrandr) reports 60. All other resolutions either do not display, or they display with horrible vertical flicker.

Here's the thing: If I roll back the drivers, this still happens. I can't get this card to drive any external monitor, no matter what drivers I use, no matter what Xorg I use, even versions that formerly worked just fine. It's like 11.12 has changed something on the device.

So I went to take a look at the card's BIOS. I thought I might use atiflash to back it up and look at it in RBE. Using these instructions I proceeded to do just that. I boot into my little DOS USB stick and check this out:

Quote:

C:\>atiflash -s 0 backup0.rom
0x0 bytes saved, checksum = 0x0000 (wait, it didn't copy the BIOS? why? sure enough the backup0.rom file is size 0)

C:\>atiflash -t 0
Pass (okay?)

C:\>atiflash -i (I reformatted the output)
adapter:0
bn:01
dn:00
dID:9591
asic: RV635/N86
flash: Unknown SPI
romsize:10000
test: 0000
bios p/n: -

So right away I am confused. Shouldn't I be able to identify my BIOS type and export it to a file? The AMD control panel amdcccle seems to have no trouble identifying the BIOS (see below). But atiflash cannot. Is there something about this model of card that would prevent it?

I looked up my card on the Video Bios Collection page but I see only 4 entries (2 really, as 2 seem to be dupes) and they are both for 512MB cards whereas mine is 256MB.

Did my BIOS get wonked somehow? Does anyone else have this card? Could someone verify whether atiflash can see/export/install BIOS to this card? Where can I get the BIOS for the 256MB version of this card? Did I leave the iron on?

Looking for a genius to provide trouble shooting tips, for at this point I can't drive any external monitor and I am confused.

deadinthewater507 — 2012-01-09T01:50:52 -05.00

When I have both VGA monitors connected, I can't switch over to my home theater system to watch a movie using the HDMI port. I can't find any documentation in the users manual or quick guide as to why this is.

By the way, I am a novice at best with software and have NO language skills, so if you can help me, please keep it very simlpe.

SM Bus documentation for E4690?

vrover — 2012-01-08T00:00:46 -05.00

I have been asking our local rep for SM Bus info for months, but of course have gotten no response back to him from ATI.

Does anyone have the command byte info for the E4690 or any other fairly recent RadeonHD GPU?

Thanks!!

XFX HD 6570 problem.

MrAks — 2012-01-06T09:22:45 -05.00

Good morning.
I bought a graphics card - XFX Radeon HD 6570. Everything is fine, but once at time flashing lines on the screen. After uninstalling the drivers the problem disappeared, but after installing the drivers (12.1 or 11.12 from AMD sties) the problem appears all the time.

Please help me.

Dungeon Siegie III, Radeon HD 6970 and CCC 12.1.

MrAks — 2011-12-29T04:07:25 -05.00

Good morning.
I have a problem with my Radeon 6970 in the game Dungeon Siege III.
After some time I play, the game really starts to cut, then pops BlueScreen and restarts the computer. In previous versions driver, it also had too.
In other games do not have.

Please help, or please fix that drivers.

12.1 PREVIEW DRIVERS BREAK EYEFINITY AND CANNOT BE REVERTED

c69 — 2011-12-15T21:48:00 -05.00

This driver has ruined my system and may require a fresh OS install as DriverSweeper can not clean up the remnants of this poor driver installation.

I installed this hoping to get the claimed small % improvement in Battlefield3. What the 12.1 drivers did was introduce frrequent BSOD and blackscreen/reboot failures, along with bad stutter.

So I uninstalled, ran driver sweeper and tried reverting to a prior version. Now my system is plagued with strange artifacts on two of the three monitors. It is as if the DisplayPort->VGA and HDMI->DVI monitors I am using only support 16 colors (only the DVI-DVI monitor works now), but instead of interpolating colors it only displays black/white and some of the primary colors, so the screens are mostly black with outline garbage.

12.1 Does something to the system or makes a change to the graphics cards that they will no longer run eyefintiy unless I reinstall 12.1. I have tired 11.10, 11.11a/b/c and installing none of these fixes the damage done by 12.1 preview.

I have tried uninstall with and without DriverSweeper, have tried all the CCC options to fix. Nothing. Cannot revert to older drivers.

Summary: 12.1 preview drivers stutter/bsod and they modify the system so that prior drivers no longer work. I have spent 4 hours uninstalling/reinstalling drivers and system only works with 12.1 now and they cause stutter/bsod.

Sadly, only eyefinity users are going to see this problem.

ATI catalyst driver 11.11 on FC15

jyotsanasingh — 2011-12-14T00:08:24 -05.00

Hi,

I am trying to run sample application "fgl_glxgears" provided with ATI catalyst driver on FC15.
I modified "fgl_glxgears" such that the window created is full screen i.e 1366x768 and setting the "override-redirect" flag such that all events go to this window.
But when I do these changes the screen starts flickering. Whereas if I just reduce the window size to 1360x768 it works fine.

Could anyone suggest what is the problem?

PS:
OS : 64 bit Fedora Core15
Platform : AMD Llano
Model Name : AMD A6-3410MX APU with Radeon(tm) HD Graphics
Kernel : 2.6.38.6
Catalyst driver Version : 11.11
GPU Name : AMD Radeon HD 6520G

Thanks and Regards,

Hi. Exception Handling Executive Summary and Abstract

VJ01 — 2011-12-10T20:08:03 -05.00

From my account on MSDN:

Useful Info for Application Developer job

-- CPU exception

---- hardware trap (device on standby but fully connected to port)

---- software trap (div / 0, etc...)

-- system software exception (OS, OS VM, Applications VM, DataBase, DataBase VM)
--application exception (additional security for consumers)

Example of system software exception

JVM or DotNet/CLR found buggy application is dynamically going to jump outside its memory and execute someone elses' instructions!

It's useful to have understanding at an abstract level to CPU with cache and memory. If a ICHV would explain using executive summary level, then it's better.

[BugReport] driver issue with outline rendering in OpenGL

corecode — 2011-11-28T18:39:33 -05.00

hello

we want to report an ATI OpenGL driver issue regarding "outline" rendering in OpenGL, i.e. rendering black lines around objects for a Comic/CellShading look.

we are using the "normal" method to render outlines:

1.) render objects normally

2.) setup OpenGL to render backfaces and as lines ( glCullFace(GL_FRONT); glPolygonMode(GL_FRONT_AND_BACK, GL_LINE); )

2.1.) switch to a simple shader that just draws black or disable lighting and use glColor(black) in fixed function

3.) render objects again

4.) reset ( glCullFace(GL_BACK); glPolygonMode(GL_FRONT_AND_BACK, GL_FILL);)

this works fine on Mac OS X with all cards, and with NVIDIA on windows and Linux. it also works fine with most ATI cards on windows/linux. however on lower end "mobility" ATI cards there are issues - the black object outlines are not drawn around the objects, but rather appear as random lines around the screen, completely destroying the image - additionally performance goes way down.

more specifically this issue appears with an ATI Radeon HD 2600 Pro Mobility in an iMac, even with the latest catalyst drivers (on windows and linux).

on a Radeon HD 4850M (another iMac) this issue exits up to Catalyst from september 2011, but seems to be mostly solved in newer versions.

we've tried various changes to the outline rendering algorithm, e.g. render the back faces first, or properly drawing lines instead of using glPolygonMode(), but none of the changes completely solved the issue on the affected cards.

you should be able to reproduce the issue on affected cards using our game:

http://dl.dropbox.com/u/7221986/CoreBreach-1.1-beta2-win32.zip

what we would like:

0.) confirmation of this problem with with a list of all affected cards

1.) this issue to be fixed in december catalyst on all cards ;-)

2.) workaround code for outline rendering on the affected cards. note that rendering black outlines as a post process (or even with geometry shaders) is not possible on the affected cards - doing black outlines as post process is much slower on the Radeon 2600 presumably because of bandwidth issues.

bye

p.s. if this isn't the proper place to report ATI driver issues, sorry. there doesn't seem to be a proper bug-report place.

Hello,

I have ATI Radeon HD2400 PRO on ASUS P5KPL motherboard.After I install the driver from your website, the screen appears green and completely distorted when I am looking the TV channels online, with Adobe Flash Player installed.I would like to know if any solution to solve this problem.I use XP Professional, Intel E8400, 2GB RAM.

Many thanks.Waiting for your answers.

screen does not flicker when i install the latest drivers!

magsbang — 2011-11-24T02:07:45 -05.00

hi!

I have ati radeon 4350 512mb ram.I updated to the latest drivers that is 11.11 but while installing the latest drivers the screen didn't flicker as it would normally do when i was installing the previous versions, it installed but it was showing that it had errors and asked me to see the log file.

I have no display problems except for the error log.I do not know how to find the log file as i closed it after installation.

I want to know two things

1)How to see the log file

2)Does the screen not flicker during the latest drivers installation.

Thanks

Support for Sony HMZ-T1 in the latest drivers for FirePro cards?

DharmaSoldat — 2011-11-23T01:02:32 -05.00

I just want to know if it will work. I'm particularly interested in the V5900 or V7900 cards. I'm looking to develop a quad buffered OpenGL application.

I've got another similar post on here that's been unanswered and I was hoping somone in here could answer this question.

Thanks in advance!

2 32-bit shaders can be used to work as a 64-bit shader?

Tekamd — 2011-11-23T00:23:17 -05.00

I have 2 ATI 4670s in CrossFire, only 1 is connected to a monitor, and I would like to keep using them as double precision on newer OpenCL GPU clients, for proteing Folding, like GPU3 from Folding@Home. So do you expert guys think is possible somehow I can get double precision? I don't have money to buy better cards now, I live in a third world Country, technology is really expensive here.

Update: I mean I have 2x320 single-precision (32-bit) stream processors or shaders, right? so what I ask if there is a way to use 2 single stream processors to make them work as a double-precision one?

Cheers.

[solved] GPU usage is 0% during hardware decoding of h264 video.

wl2776 — 2011-11-21T04:23:23 -05.00

Hi all.

I've recently started learning hardware accelerated video decoding and cannot find an error in my code.

My test program reads h264 video frames from the mov container, decodes them and then drops.
It uses FFmpeg to parse the file. I've also copied some code from the VLC player to set up HW acceleration.

The problem is that it seems the hardware acceleration doesn't work, although calls to DXVA API can be seen in DXVA checker.

The Process Explorer application shows that, compared to pure software decoding, the CPU load is the same.
The only difference between software decoding and my "hw accelerated" decoding is that CPU spends some time in
kernel mode (process explorer shows red line on the CPU load graph).
When I switch off my "hw accelerated" decoding, the CPU spends all its time in a user mode.

GPU load is always 0% both with and without "hw acceleration", however, video memory is used, when hw acceleration is on.
DXVA Checker also shows calls to DXVA2 functions (CreateDevice, BeginFrame, GetBuffer, DecodeDeviceExecute, EndFrame, etc).

I use ATI Radeon HD 4550, my OS is Windows 7, I've installed the latest drivers from the AMD site.
My code is here: http://pastebin.com/UsgggaEN
I use version git-d049257 of FFmpeg libraries, downloaded from git://git.videolan.org/ffmpeg.git, compiled with gcc 4.6.1

ATi Quad Buffer

steeley — 2011-11-14T10:57:45 -05.00

I have downloaded the AMD Quad Buffer SDK (with sample) but I am unable to get working on my current setup.

Installed in my machine I have a ATI Radeon HD 5870 and have the latest drivers:
Driver Packaging Version      8.892-110914m-125030C-ATI
Catalyst Version                    11.9
Provider                                   ATI Technologies Inc.
2D Driver Version                   8.01.01.1186
2D Driver File Path                /REGISTRY/MACHINE/SYSTEM/ControlSet001/Control/CLASS/{4D36E968-E325-11CE-BFC1-08002BE10318}/0000
Direct3D Version                   7.14.10.0860
OpenGL Version                    6.14.10.11079
Catalyst Control Center Version   2011.0908.1355.23115

According with the documentation that comes with the SDK my graphics card should be supported. However I tried running the SDK sample with my PC connected to a Benq MP670 projector running at 1024x768 @ 120hz but the demo only runs in mono.

I've tried debugging the demo and it seems to fail to create the AQBS surface required to perform the quad buffering.

Is there anything I'm missing should there be something in the Catalyst Control Centre to enable DirectX Quad Buffer support?

Thanks

About Optimization of Opteron

francium — 2011-11-14T05:43:34 -05.00

I'm benchmarking a Opteron cluster using High Performance Lapack .

When compiling with PGI Optimization option '-fastsse -tp=shanghai-64' , The final performace is a little bit LOWER than just use ' -fastsse'

When compiling with Open64 with '-O3 -march=barcilona' , the result is the same, a little bit lower than just use '-O3'

I suppose it should be faster when specifing the target processor. but result is weird.

OpenGL ES 2.0 native (Catalyst 11.10) vs. Imagination Performance

gex2k11 — 2011-11-11T07:15:46 -05.00

Hello everyone,

I recently tried to exchange the Imagination OpenGL ES implementation on Windows against the native implementation inside the Catalyst drivers, for which i expected performance enhancements.

Therefore i wrote a statically linkable wrapper, which loads the functions and binds them to function pointers, which are called from an own OpenGL ES implementation.

The results worked just fine, but when comparing fps counters I noticed that the Imagination SDK is still a bit faster.

Does anyone know a reason why it is like that ? I'm using Windows XP with a Radeon HD 4350 and Catalyst 11.10 drivers.

Kind regards,

Georg

External interrupt intercept in SVM

hzzhang — 2011-11-10T10:01:13 -05.00

Hi,

I have a question about the external interrupt inercept in SVM.

If I hope whenever an external interrupt happens during the execution of the guest it will cause an VM_EXIT, is it enough to just set the intercept INTR bit (0xC) of VMCB before launching the guest through VMRUN? Or does the hypervisor have to do some specific configuration for the PIC or APIC?

flgrx driver eats a large amount of memory when the same texture is mapped many times

dephlector — 2011-11-09T13:03:32 -05.00

Hi,

I have an another problem with the fglrx driver. When doing simple things like showing a single texture, the driver eats a large amount of memory - somewhere between 300MB and 900MB. I think the memory is allocated from the kernel module, because the process shows small amount of memory used, but the free memory of the system decreases. I can see in /proc/meminfo that the "HighFree:" field decreases when I run the sample program. The decrease is relatively slow, at around 10MB/sec.

I am attaching the sample program so that it is seen exactly what I am doing. The program requires a parameter that tells it how many lines from the image to transfer at once. I noticed, that when the texture is loaded in smaller chunks (800kB or so) the problem dissapears. Only when I load the texture with chunks of 1MB or more the problem is seen.

In other words if the program is run with parameter 200 - no problem. If the parameter is 300 or more the problem appears.

Can someone point me if I am doing something wrong or if there is a bug in the driver? And is there a workaround in this situation?

Where to get a windows driver for HD 5650 that support openCL ?

qilux — 2011-11-09T09:21:11 -05.00

Unlike the driver name (vista32_win7_32_dd_ccc_ocl.exe ) for desktop, the dirver name (mobility_vista_win7_32-64_ccc.exe) for mobile do not include phrase "ocl" and "dd", does it means this Package only includes Catalyst Control Centeris ?

Linux 2.6.x kernel lockups with Ati catalyst fglrx driver 11.x

dephlector — 2011-11-08T05:02:55 -05.00

Hello,

I am having a problem with the ati fglrx driver lagging the linux kernel. I have tried with different kernel versions (2.6.24, 2.6.32 and 3.0.4) and with different catalyst driver releases (almost all of them from 11.1 up to 11.9) and the behavior is the same.

The problem:

I am developing a kernel driver, which reads and writes messages to the serial port. It has stringent latency requirements - 5ms inter-character timeout. When running the communication from a text console, or from Xorg without the ati fglrx driver loaded everything works fine - the latency requirements are easily met (the characters come with a delay of 1-2 ms)

But when the fglrx driver is loaded timeouts do occur very often. I guess my IRQ handler is delayed from being called for more than 3 ms. This means that the kernel is blocked in some way for such a large period.

After some investigation I have come to the conclusion that the blocking occurs when there is some heavy activity from the video card: swithcing window tabs or desktops, dumping a lots of output on the terminal application (KDE's konsole). If there is no activity the timeouts do not occur.

I can provide mor information and logs for my system as needed.

Strange bug when linking GLSL shaders twice

lvezzaro — 2011-11-04T06:09:58 -05.00

What I'm going to describe is a very strange bug, that took me a day to find out in our software.

What we are doing is putting all the shader code in a single file, and using preprocessor definitions to compile only parts of the shader (e.g. #define VERTEX_SHADER is pre-pendended to the shader code to compile only the vertex shader part of the file).

This worked well until I wanted to add geometry shader support. Since those are an optional part of the pipeline and since a different geometry shader is needed for different primitives, I couldn't afford to modify all the existing shader files to add pass-through geometry shader code.

So what I did is try to first link the shader programs by including the geometry shader, even if it has no main(). Then if the link fails, I detach the geometry shader from the program object and link again.

To my dismay, shaders that worked before, suddenly stopped working when using this approach.

I was able to reproduce the issue in a simple program. On my machine (ATI Firepro V7800), I only see a blue background. With an NVIDIA Quadro it works just fine.

You can find the program here (if a page shows up instead, click the first link on the page): http://lvezzaro.altervista.org/GeomAti.zip

Either avoiding to attach the empty geometry shader (by commenting line 150 in flat.cpp) to the program or changing the line:

float c = 1.0;

to

const float c = 1.0;

in the shader code will also display the white triangle, in addition to the background.

To build the code on Windows, you'll need Visual Studio 2008 or later (external libraries are included).
To build on Linux you'll need Scons and development libraries of SDL and glew.

I encountered this problem in both Linux and Windows, I'm using the latest driver.

Please let me know if you are able to reproduce it, and hopefully fix this.

Best regards,

Luca Vezzaro

ATA_PASS_THROUGH not workig on AMD controller

arunalapati — 2011-11-03T05:31:43 -05.00

Hi,

I'm trying to develop an application which tries to update firmware of the SATA disk. controller connected to the PC is "AMD AHCI SCSI BASED RAID CONTROLLER".

I tried all the 3 approaches: ATA_PASS_THROUGH(12), ATA_PASS_TROUGH(16) and WRITE_BUFFER (SAT-2). But, none of them seems to be working.

command execution is failing with check condition bit set and the sense buffer returned is invalid.

Please help in this issue

Unable to start ATi Catalyst Control Center

Shooter__Andy — 2011-11-02T05:02:44 -05.00

I have a problem with CCC that I wouldn't ordinarily complain about, since I don't really need anything from it, except one thing - display over/underscan setting, which, apparently, can be modified exclusively from it. So I need to start it, but I can't. Everything installs fine and without any errors, but CCC just wouldn't start properly after that - it appears in the process list for a couple of seconds, does something and disappears without any error messages.

I've heard this problem is common for updating without complete deinstallation and I think that might be the case here, since Windows could've downloaded some version of a driver on its own when I installed it (~a week ago now), but I doubt it is the case.

Anyway, I've tried deinstalling the driver in every conceivable way, ending up with using specified programms like Revo Uninstaller Pro and removing EVERYTHING associated with CCC that was left on the disk manually, but it still doesn't work.

Is there any way to fix this? Because right now my display has very noticeable borders and the image is smaller than it should be, resulting in a blurry image, and I can't fix it without CCC.

Catalyst Driver Win7 64 Bit Problem

droopy — 2011-10-30T13:49:12 -05.00

I have a problem with Catalyst 11.9 using my Notebook HP dv7-4065dx.

My graphic card is Radeon 4200 series.

I connect my HDMI cable, and driver detects it as DVI.

I use FORCE method and after many retries, it detects it correct as HDMI and with AUDIO.

I am using it with a LED Philips Monitor. Strange thing is that Fake DVI connection opens in FULL TV resolution, but HDMI keeps an empty black space. Even if i out maximun resolucion on extended mode of screens.

Reading old posts, i notice solution is SCALE or overscale in Catalyst, but this new version 11.9 do not permit me to put SCALE 0%.

Any solution or ideas to view HDMI in maximun screen? As using my TV to enlarge it is not good.

is it a bug?

GLSL flat varying problem

Dark_Raven — 2011-10-30T10:52:21 -05.00

I've found out that when I use flat varying int inside vertex shader and read it's value inside geometry shader, the shaders are compiled fine, but at link I get that both shaders failed to link and 2x "unexpected error". Removing line where I assign value of that varying into other variable fixes the problem. Also defining varying as float fixes it.

I've Radeon HD38700 whit Catalyst version is 2010.1105.19.41785. It's like the last good driver for my card (even though there are these bugs)...

Please, I'm not spamming, I need help;

Been wanting to do (this) for year's, hence, it's been on my 'back burner' - 'to do' list, as I've been amidst, for a long time, life stuff, ie: homelessness, lack of housing, misc; anyway, thing I'm at a point I can further inquiry and thus, try to gather - narrow, nip in the bud, the info I need, EVEN THOUGH AMD, I know I gotta 'buy' through one of your 3rd party's, I know, but I can still get pre - info first, from you before I go unto one of your 3rd party's. As such . . . As above, I do want to do that AMD 99, and either from/through you or (?) I heard: (7) component's, more less, make up (1) desktop. As such, what I care about the MOST is the AMD 99; all the other component's can be basic, I don't care. I saw a (above) processor - complete desktop for $800 plus, uh, no. The processor, yes, I want, BUT, aside from no internal hard drive, as I got my own, it's the other component's, compatible and cheap/low in cost I need to know, BEFORE, I then go to one of your 3rd party's, NOW, are we on the same page??? BUT, I need to know: what are the simple, basic other component's, which can be generic, cheap, not high end, misc, thus, to work with and make that AMD 99 work, be it ram, graphics, misc. I don't care, I just need to know what is/are the item's that I could get that are generic and basic and a ideal price quote, before I go to one of AMD's 3rd party's; WHY? because like buying a used car without the engine, I'm gonna take my 'ok' 100 gb Samsung internal drive out of my last pc, as the other inside tower component's are bad, trust me, and put that 'ok' 100 gb Samsung internal drive into a new tower desktop case/casing. And note I do have (2) separate external drive's, which I never keep plugged into a desktop, Ionly plug them in when I'm off the web/internet - then to back up when needed then I unplug them, thus, a hacker, misc can't ruin what's not plugged in, get it? One external drive has last known old pc os backed up and the other has solely My Doc's, misc. No worries, I'll do update's, thus, after (down the road) with getting new AMD 99, misc desktop. But I gotta do thing's step by step. And first, again, like I said, I first need to know, before going to one of AMD's 3rd party's, is to know what other component's all basic (which I can increase/upgrade later), I just need to 'do this' already, it's been year's on my 'to do' list, you know. Thanks, much love, cuz, I ain't doing intel, it'll always be info/product (s) - wise = "AMD", nothing but love for ya. smile. List the item's, heck type something in MS Word then you can copy and paste your text into a compose email back to me, hence, no rush. As above, we know I want that AMD 99, but it's the other component's of the 7 - which make up a desktop thatI need to know, as I think, maybe, with a screw driver, misc, I may have to get/buy each of the 7 component's individually, and thus, in my home, put them together myself, inside the/a new tower, case/casing, as I will need to know how to do that, which Ican do, but don't wanna self screw it up, as to why I trust ya AMD, ok. WE, misc can do this. I seriously believe that. If I don't 'know', I can 'ask' AMD, misc. Get back to me, only when you have a chance, thanks, I appreciate it. But I know myself, I gotta self move on this (pre wise), before I go to one of your 3rd party's AMD. Also, separately, I heard/researched: Time Warner has got (now) 50 mb web speed service (down the road), that 50 mb + AMD's 99 quad core, and BAM! I'm jamming, cool, happy. No duel core or less for me.
