u forgot to install audio related file during the setup.

do u use the active fan NB block comes with R3E?
idle should be around 50C load 60C ish
U dont need IOH that high unless BCLK > 200
Not all dual gc requires high IOH

reapply TIM and reseat the NB block firmly.

try dont OC ur proc bro, i wanna see what happen when u're running at lower power consumption
cf wont be that high bro, gpu2 will be less than 10C higher than gpu1, but ur 255C max looked quite a buggy issue of gpu-z
check ur psu power connectors for bent pins etc, sometimes imperfect sleeving causes bad results

Sapphire 6870 for RM765
Link

6950 RM10XX
6970 RM14XX
CEX is taking pre-order now, release on 15/12/10 (Next week)

Yes 6970 is slower than GTX580, i smelled this when AMD delayed releasing it few weeks ago. Duno why they even make this 69xx if cant beat GTX580.

Reminds me of mouse cursor bug, they took time to fix it.

Cytech = CEX

Software Description

This file contains all the tools required to flash your AMD Radeon HD 6950 to a HD 6970 (and back in case of problems).

Recently it became apparent that the Radeon HD 6950 in fact is a 6970 with shader processor clusters disabled. You'll need to re-flash your card though. You can perform the flashing process from within Windows and het, thanks to AMD's new Dual-BIOS feature if something would go wrong, you can switch back. We successfully tested an unlock on a HD 6950 cards. Other have tried one AMD engineering sample, one HIS media sample and one ASUS retail card. All of them unlocked perfectly and run at HD 6970 speeds now. Your graphics card needs to be a reference design sample.

The Download & instructions are courtesy of TechPowerup!

1. Grab ATI Winflash from here (32 & 64-bit).
2. Download HD 6970 BIOS. The Sapphire one I linked to will work on all reference design cards from any vendor.
3. Make sure the BIOS switch on the card is set to the 1 position (pictured further down if you don't know where it is).
4. Run ATI Winflash, click Save to save your BIOS, so you have a backup in case something goes wrong.
5. Load the HD 6970 BIOS into Winflash by clicking Load Image, followed by Program.
6. Let the flashing process complete and reboot your system.
7. Check the shader count using GPU-Z, it should show 1536. Make sure you use the linked version of GPU-Z, the official 0.4.9 version does not support HD 6900 Series properly. If you see a shader count of 1600, your GPU-Z version is outdated and you should get the one from the link here.
8. To ensure maximized performance open Catalyst Control Center, go to the Overdrive tab and set the PowerTune slider to the +20% setting. The "Testing" section of this article has more data on that.
9. Check stability in Windows desktop applications and games.

If you get an error like ID mismatch or Could not erase ROM, then you'll have to do some extra work in a Windows command prompt (or DOS): Run atiwinflash -unlockrom 0 followed by atiwinflash -f -p 0 bios.bin where bios.bin is the path and filename of the HD 6970 BIOS you downloaded.

Yes, how can 6870CF win when single 6870 is not even close to single GTX580. If ure talking abt multi GPU scaling that's different thing. Ppl are talking abt when ure adding a 2nd card, how far is the performance gain. CF or SLI scaling is good if it's close to double (100%) performance of single card. In this case CF amd6000 scales better than SLI gtx500.

I believe thats not supposed to be the final price
Should be just slightly more or less than 5970 price tag.
