This is why I will never use Asus software again. It's always junk.

Lol ,it is the only way now for voltage control...didn't try TriXX yet.

I tried adjusting voltage in smartdoc, not sure its working for me. Can't move 10mhz even with a healthy bump to voltages.

sapphire, flashed yesterday, working so far..

artifacts in atitool tho.

Are there any issues with oc beyond CCC limits and with crossfire? (ULPS)

It's the scanner. People have posted that they get the problem in stock 6950s and 6970s, even though games and other benchmarks run without problems.

If you do have issues with the 6970 BIOS, just use the modded 6950 BIOS that keeps the 6950 memory timings.

3rd gigabyte 6970 went through.

Powercolor flashed with Powercolor 6970 bios unmodded working well OC to 950/1450 easy :D

I went reading about the shader unlock bios that keeps the 6950 1.1v and 1.5vdimm. So I flashed to it, unlocked shaders and kept 6950 volts, 925 restarts now but I can run 900/1375....

So for 24/7 use people might want to compare... seems to me right now 6950 volts with 1536 shaders makes more sense since my core doesnt scale for crap with 1.175 anyway and I havnt really pushed the memory above 1400 to find out how high it goes.
From past ddr5 ATI cards seems kinda pointless anyway since 1400 is already 5600mhz effective correct?

I flashed 2x HIS 6950s with the TPU unlock kit using the 6970 bios.

Got it 940/1400 +20% stable in Metro 2033 CFX mode but is hot and fans spin up loud. No problem. 950 core crashes out the driver, but not windows.

But I tested EDUKe (openGL) at 940 core and it crashes out the game.

Drop it to 920 core, +20% in ccc, Metro stable, Eduke Crashes.

Flashed the unlocked 6950 with shaders only and it only lets me OC to 840 / 1250 ram. Eduke still crashes !!!!!

So flashed it back to 6970 bios and have it at 920/1400 +20% CFX for daily use.

Can you guys who have unlocked your 6950s test openGL games for stability? Such as Doom 3, Prey, EDuke or any other test? It seems to put MORe strain on the cards than directx titles? or perhaps Eduke is just a not support engine in ATI drivers.

Nvidia drivers runs all opengl games with no issues.

I can't get Doom 3 to run properly (keeps reseting to 4:3 screen rations) so cannot test at 1080p native resolution.

with 6950 unlocked bios i get no artifacts in atitool. But anyone knows a 6950 bios with ccc overclocking unlocked?

I was running Darkplaces just fine which is an OpenGL Quake source port. Are you using the latest version of eDuke32?

Edit, yup eDuke crashes for me too. It didn't with 10.10e on a 6870. I guess that we should report it to AMD.

Just ordered a pair of MSI 6950's before the new batch hits :)

i have confirmation that atitool artifacts on stock 6970 also, regardless of anti aliasing. so it should be considered quite safe to use 6970 bios..

Am I the only one hitting 90-92C temps during heaving gaming/benching?

my fan is set to gradually ramp up to 60% when the card hits 60c using the fan profile settings

Playing bc2 I rarely hit 60c, but I have the card flashed to the unlocked 6950 mod bios for shaders but retains the 1.1 vcore and 1.5vdimm over the 6970's 1.175 and 1.6.

Clocks are 900/1400

I think the bios changes the temps, and I don't think it's just the voltage. ON the modded 6950 bios with smartdoctor at 1.3 I only got upto 77c with the core at 1000mhz which does't make sense where I can be in the high 80's or upto 90 with the asus 6970 bios with the core only at 920.

Rattle, what program are you using to OC to 900/1400 with the unlocked shader 6950 bios? CCC? CCC2?

When I unlocked the shaders only, I cannot OC past 840/1250 with CCC2.

With the 6970 bios, I can OC up to 950/1450 via CCC2.

Has MSI afterburner been updated yet or has there been a new beta to allow voltage adjusting on these cards? I'm getting extremely impatient:confused:

Removed

Just go to the afterburner.cfg and change EnableUnofficialOverclocking to 1 and restart AB.

with fan on auto, i reached those temps as well, just replace the TIM, i lost about 5c on load by doing that, just make a custom fan profile on afterburner, problem solved.

I haven't gotten around to replacing the TIM yet but I've been using Afterburner to set a custom fan profile as well. My temps are staying in the low 70s and the card is usually under 50% fan speed.

I may look into an aftermarket cooling solution for this card though. It isn't bad now but during the summer I'm sure that this card is going to get loud.

yea i replaced the TIM and shaved off about 5C as well.

I reach 92°c too now with 910/1450/+20% and running FuMark stability test.
No worries, it's the same temperature than a stock 6970 with the same test.

Man ,I love the silence of my unlocked 6950 with wc. 1.34V 1075/1475 @30degrees load, no heat,no noise :cool:
