The Radeon HD 6950 gets a saucy XXX Edition from XFX, offering increased GPU and memory clock speeds at the cost of a lowered 1GB memory capacity. Strangely it's offered at the same price as 2GB offerings based on the reference design, but it does offer a custom cooling solution. We put the HD 6950 XXX to the test to see if it can keep up the 2GB reference models, even with the total memory slashed by half.

What is the software used for overclocking?

I used MSI Afterburner. Here is a link http://event.msi.com/vga/afterburner/download.htm

Thank you!!!

Downloaded current and Beta versions of Afterburner and could NOT get past 840/1325 clocks. Could change voltage. Read about changing the cfg file but could NOT "save" changes.

How were you able to get it to change the clocks??

Try this


1st - Remove the current version and download the latest MSI AfterBurner and install.
2nd - Locate the folder where MSI Afterburner installed to, open it, and locate the CFG file named MSIAfterburner. When you 1st double click this file it will ask you what program you want to use to open it, choose "Notepad" and click "ok" Once you have the MSIAfterburner CFG file open in notepad you need to change a couple of settings near the bottom:

UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode = 1 (to keep PowerPlay active (may not work on old ASICs), 2 to traditionally disable PowerPlay or to 0 to temporary disable unofficial overclocking path)<--Do not type this, just for reference I have mine set to = 1

After you have made these changes, DO NOT forget to click "file" and "save" before exiting notepad, or your changes will not take into effect!

When I "Save" a message window titled "Confirm Save As" tells me that MSIAfterburner.cfg already exists and asks if I want to replace it...I save it a notepad message box indicates "Access Denied"...

Should the MSIAfterburner file be named something else?

You are going to need to change the permissions for the file. To do this right click on the MSI Afterburner CFG file and select proprieties. After this go to the securities tab and select advanced. Then set the permission to full control. After that you should be able to change the file.

Thanks very much for your help! Got it working.

Great. Glad it worked.
