You mean Version 2.1.0 Beta 4?

Beta 2 included voltage control for 6850s, Beta 3 included voltage control for 6870s, and Beta 4 includes voltage control for GTX 580s.

I've noticed 6870s clock to about 990mhz - 1035mhz and 6850s clock to 940mhz - 1000mhz. These are stable clocks, not those pointless and misleading benchmark OCs.
My 6870 has a slightly weaker core then, I can only get around 980mhz and after that, I start gettin small artifacting in furmark. On the stock cooler though, I could only get 950mhz.

My 6850 is a dud also. I can only do 910mhz on stock voltage, and with a voltage bump I can get to 930mhz stable. As I only tested for 1 day I may be able to reach 940/950mhz under better conditions.

But what I found interesting was that my VID is 1.149 and I can run 0.987v stock clocks 100% stable.

Ya, I checked the Sensors tab in GPU-Z to see if the voltage was actually changing or not. It wasn't changing this whole time.. I left a post on the how to overclock your ATI guide thread but no reponse yet T.T

Sigh L4D2 isn't working. I posted a thread in the pc game sub forum, but its saying they don't have the ASUS 6870 in their data base. So I can't run the game with the video card.

I have a 6850. I would like to join this club.
Also, what OC'ing programs do you use? Afterburner will only let me go to 850 core, which is weak.

Ok heres a quick comparison of my old 5850s to my new 6870s

First 5850s @ 950/1250



Uploaded with ImageShack.us

Now my 6870s Stock



Uploaded with ImageShack.us

As you can see my 5850s had lower mins, and averages but they had higher max. The 6870s are also more consistent with the fps. I'm pretty happy with my purchase

Use Afterburner 2.1.0 Beta 2 or later. Then enable Unofficial Overclocking.

I guess I didn't have the latest after burner. Thanks skillzkillz even though your comment was for someone else

and thank you for your avatar. I never get tired of looking at it.

How do I enable unofficial overclocking?

Go to your MSI Afterburner folder, open MSIAfterburner.cfg with Notepad, then edit EnableUnofficialOverclocking from 0 to 1. Save and overwrite as All File Types.
See above.

Quoted from How To: Overclock your ATI thread


Quote:
Step 2: Download GPUTool to an accessible folder and run it. Download MSI Afterburner (even if you already have Afterburner on your PC make sure you have it updated to the latest version). Navigate to the folder you installed it to (usually C:\\Program Files (x86)\\MSI Afterburner) and open the MSIAfterburner.cfg file using Wordpad. Find the following setting:
Code:

EnableUnofficialOverclocking= 0

and change it to:
Code:

EnableUnofficialOverclocking= 1

This will allow us to bypass the limitation that stops you from passing the limits of ATi Overdrive (This tip was found on HWBot news). A BIOS flash is not necessary to do this, you just need to edit the file . If you get an Access Denied or permissions error see the 'I Get An Error When Saving The Config File' section at the bottom of this post.
Run MSI Afterburner.
