If anybody is still searching for simple answer, then in Windows 7 it's as follows: Open Device Manager Expand Display adapters Right click on a graphic card and choose Disable Wait till the screen goes back and repeat step 3 with Enable. That's it.

On AMD Eyefinity Technology, there is this remark at the bottom: Driver version 8.66 (Catalyst 9.10) or above is required to support ATI Eyefinity technology and to enable a third display you require one panel with a DisplayPort connector. Do you have one screen connected with DisplayPort?

This cannot be solved with a passive adapter. Issue is in hardware and comes down to signaling on DVI, HDMI and DisplayPort. If I recall correctly DVI and HDMI require an own clock signal per output. Because DisplayPort is a package protocol it requires only one clock signal per card. ATI Radeon HD 5000-series has two clocks for DVI/HDMI so it is possible ...

To fix this: Uninstall any ATI drivers on your system. Run the CCC installer but I suggest canceling after it extracts the files. Navigate to: C:\ATI\Support\10-x_vista64_wi n7_64_dd_ccc_enu\Config EDIT InstallManager.cfg Change WorkaroundInstall=false to WorkaroundInstall=true Run Setup.exe and the CCC should install without a problem

I had a similar problem on windows 8 and found that just changing the screen resolution and changing it back again resolved the corruption.

Enabling GPU scaling should solve the problem. Open Catalyst Control Center Select Desktops and Display At the bottom, click the little arrow on the upper right corner of the selected monitor and click Configure In that screen make sure "scale image to full panel size" is selected and GPU scaling is enabled If that doesn't solve your problem click ...

The last time I needed to do this, I had to run two separate X sessions, made by having multiple Screen sections in xorg.conf, and it involved a lot of cussing. There's been a bit of overhaul to xorg since I had to do that, but I can't imagine what you need to do is too different (other than I think that by default xorg doesn't actually spit out a conf file ...

If you press Shift + Esc while in the browser it will bring up Google Chrome's internal Task Manager. If there is a process titled GPU Process, then that means Chrome is using hardware/GPU acceleration in order to display/render a particular page.

You can use following URL to check if GPU acceleration is enabled for video decode in Chrome: chrome://gpu/ Graphics Feature Status Canvas: Hardware accelerated Compositing: Hardware accelerated on all pages and threaded 3D CSS: Hardware accelerated CSS Animation: Accelerated and threaded WebGL: Hardware accelerated WebGL ...

I solved the problem by going into the CCC, into Power/PowerPlay(tm) and un-checking the "Enable Vari-Bright(tm)". After clicking apply, the problem was gone.

I solved it! You need to unplug the HDMI cable before you do this because the driver doesn't show up in the list if you don't. If you locate the driver in "Properties", right click the speaker down by the clock on your desktop toolbar. Select "Playback Devices". There you should have the "Digital audio (HDMI)" icon. Click it and select "Properties" at ...

The upgrade advisor only tells you that Windows 7 will work. It doesn't guarantee that your hardware will perform at optimal levels. Most likely, the Vista driver issued by AMD will work fine. But due to the age of the device, AMD never took the time to validate their Vista driver with Windows 7. The similarity of both operating systems, generally, ...

From some AMD presentation: Each SIMD unit contains 16 stream cores, and each stream core houses five processing elements. Thus, each compute unit in the ATI Radeon HD 5870 has 80 (16 × 5) processing elements. Analogue for CUDA core is Stream core, and SIMD unit is analogue to nVidia's Streaming Multiprocessor. The difference between CUDA core and ...

Right click the Desktop then select Screen Resolution. The displays should show up there and allow you to modify the behavior.

This is a common problem with default settings of Catalyst Control Center. To fix: open Catalyst Control Center go to My Digital Flat-Panels choose Scaling Options slide the slider all the way to the right (so that it is a 0%)

Have you looked at the CPU and motherboard temperatures during these performance drops? It could be that either your CPU or motherboard chipset are overheating and throttling back and so reducing performance. You can check most temperature sensors using Speedfan

Your graphics card has two main parts to it, the Graphics Processing Unit (GPU) and the Memory that the GPU connects to to store data such as graphics textures. You can push each of these units to higher speeds separately, hence you have two sliders. The highest you can push these two sliders does not solely depend on how hot the components will get but on ...

Graphics card performance figures are a boggy minefield of confused and conflicting information. The memory clock figures you listed are probably equivalent in that the AMD is listed as 1 real GHz, while the Nvidia is 4GHz "effective clock" with a 1GHz real clock that is "quad pumped". Chances are the AMD is quad pumped too so the actual memory bandwidth ...

Yes, PCIe 3.0 is backward-compatible with all prior PCIe implementations. http://en.wikipedia.org/wiki/PCI_Express#PCI_Express_3.0 However, because PCIe 1.0 maxes out at 2.5 gigatransfers per second (GT/s) vs. PCIe 3.0's 8 GT/s, your video card may not perform as well as you would expect when installed in a PCIe 1.0 slot.

I've done a bit of googling. Apparently, it is possible to run PhysX in software on an ATI card, which should apparently be built in. However, for hardware accelerated PhysX, you will need an Nvidia card, and furthermore, as of the most recent drivers update, can't even have an ATI card in the same machine at the same time. It's possible this will continue ...

You should post exactly what PSU you are using, as this is a crucial requirement for the HD 6990. But i will go ahead and post my findings anyway. From the AMD Gaming Forums the powerdraw can be up to : 150W + 150W + 75W = 375W. But a special Overamp feature allows it to consume 187.5W from the two 8-pins connectors. So all in all the card can draw up to ...

Solution that worked for me follows: I have a Sapphire ATI PCI Express 5570 as well and experienced the exact same 0x000000CA BSOD in Windows 7 when trying to install drivers for it. I tried the Catalyst driver on Sapphire's website as well as on ATI's website. I tried Catalyst version 10.4, 10.5, and 10.6 with the same issue. I also tried updating the ...

Eyefinity is only supported on the Radeon 5000 series, so you would need new video cards. From: http://support.amd.com/us/eyefinity/Pages/eyefinity-dongles.aspx ATI Eyefinity technology is supported by graphics cards in the ATI Radeon™ HD 5400 series and higher.

Current state - CUDA It is currently not possible, as PhysX drivers do now work through any universal interface, they talk to nVidia card directly in a way which is not compatible with other HW vendors (CUDA). Possible future development - OpenCL I think it is quite likely some solution will be released which will be using open standard line OpenCL for ...

It depends on the single video card you are comparing the CrossFire combo against. In some scenarios, a single card could outperform a CrossFire/SLI setup. Here is a good post that explains in more detail: http://www.tomshardware.com/forum/245454-33-crossfire-faqs

It depends what operating system you are going to use. I think this is possible in XP however I know for a fact that you cannot in Vista and I remember hearing that they are going to re-enable it in Windows 7, however I have not heard about it for ages or had a chance to test it. I would say get an adapter quick - you can get them for next to nothing ...

Upgrading the graphics on a laptop is generally not possible. The graphics is embedded directly as part of the laptop motherboard. The "switchable" indicates that the operating system is able to intelligently "switch" between the Radeon and another integrated graphics on the CPU, based on the need of the application being used. Also changing the graphics ...

A workaround without loosing VA would be to use the 12.6 AMD proprietary driver or prior. The tearing regression seems to start with 12.8. http://support.amd.com/us/gpudownload/linux/previous/Pages/radeon_linux.aspx Just enable execution permissions, run the script with root privileges and build a package and install it.

As far as I know Need For Speed Underground don't have widescreen support. There is a patch for it here.

You can also find a Motherboard that supports 7 PCIe cards. Checkout this one by GigaByte: http://www.gigabyte.com/products/product-page.aspx?pid=3434#ov Of course, as the other guys said, you will have to find a way to manipulate the cards and cool the system...
