What are you getting when clocking?
900 on the core with stock volts seems pretty damn stable, it's been able to run every benchmark i've thrown at it to date.
The memory has been a bit... iffy, with RC2 driver 1500 would run everything, but after installing RC3 it would grey screen or just generally freeze up and i'd have to hard reset the PC. But, i'm not sure if it's down to the driver or my card has sort of 'burned in' so to say. Either that or it was when i tried to run over 1500; 1525 gained no fps and 1550 froze up immediately in crysis... after that i installed RC3 and that's when 1500 became unstable. So it was either me running it at too high frequencies and hindered the memory or it was the driver... Still, 1450 runs perfectly fine.
Hi mate
Do you have a link to the driver you were using?
Thanks
Here you go: http://support.amd.com/us/kbarticles...12ahotfix.aspx
RC2 is nonexistent i think, AMD had overwritten the original 10.12a with RC3. But RC2 had problems with OpenCL i think, because i wasn't able to run the physics tests on 3DMark11, after installing the latest AMD/ATI stream it was fine. But before i installed RC3 i uninstalled everything, even stream, and the physics tests worked ok after.
Unless the driver on the CD is RC2...
900/1355mhz here 2 cards.
still waiting for oc tools.
Nice Gaul ;) Temps?
I see, i may have to give that a go :D

My GPU score isn't as good though :( 5196 compared to your 5219.
Did you install the 3DMark11 1.0.1 update?
Edit: I beat you on this one though :p:

@ ^ = only coz CPU......see i'm only 9550 @ 4 gh
What are you guys using to bypass the CCC's limits? Afterburner 2.1 beta?
Yeah i know, was only joking ;)
I just realised as well, 24,600 is quite bad for a 4GHz HT chip isn't it? I clearly remember getting closer to 25,000 before... not sure what i did different, maybe i disabled start up programs last time, or even services :confused:
I'm just using v2.0.0
:D
here q 9550 @ 4.37 GH

Haha, nice. Beat my GPU score again :argue: :rofl:
How do you do it? :shrug:
@ ^ = easy........ CPU clock........
first only 4 GH, now 4.37 GH, that's ALL
Yeah i realised that, but you seem to consistently beat my GPU score :p: Albeit by hardly anything, 0.2fps at most.
I have run into a problem
I installed the hotfix drivers ran 3D Mark 2011 and it ran fine
But Heaven Benchmark won't run.
Any ideas?
I'm getting P19589 3DMarks in Vantage is this right?
P4882 in 2011
P19k vantage and P4.8k in 11 sounds alright. As long as you're getting 18k GPU score in vantage and at stock then that's fine.
Does heaven run in DX10, or is it just DX11 that's causing the problem?
That was the the 'high' setting :)
This is the performance score:

God knows what's going on with your heaven :( you're using v2.1 ya?
yeah its 2,1
I have reinstalled both driver and heaven and it still refuses to run.
It would be anything to do with having a 6870 first?
I have searched the registry after uninstall and found nothing
what does the power silder do in CCC?
shall I try the standard 10.12 drivers?
Broke 5k

P5092 840/1325
Hmmm, i just ran 3DMark11 at those clocks (except CPU @ 3.8GHz), and i got P5167. GPU score of 4792. Now while that's hardly a difference, Gaul was getting a better GPU score than me so it's only logical to think that yours is slightly low compared. Could just be a 'bad' run though.
Your heaven problem has gone over my head, have no idea what it could be. I wouldn't bother trying the 10.12 drivers, they don't even properly support the 6900 series. Guess can always try though, just to see whether it is a driver problem or not. What steps did you take to uninstall your old drivers?
And the power slider, it just sets the maximum amount of power that can be drawn. 0% i'm guessing would set the TDP at ~150w, so 20% + or - around that. So for example, while playing normal games, your GPU would be drawing within the 150w TDP so clocks would stay at 100% of whatever was set. But in cases where a certain program will draw ~110% power, it would go over the ~150w TDP and the card would throttle clocks to keep the power draw within the set TDP. So in those cases you would have to set the power slider to +10% to make sure the power draw is lower than the TDP that's been set. Perlin noise is obviously the main example, at stock clocks and 0% on the slider, it would throttle down because perlin noise would be drawing more power than you've allowed through the power slider, but add 10% and clocks can run at full speed as you've now allowed it to draw more power. Overclocking will of course draw more power. So where +10% would normally keep clocks from throttling, with the overclock it might need to be +15% to stop it from throttling. Considering +20% is the max, this makes me think that with more overclocking (with added voltage), it would be nearly impossible to stop it throttling in cases such as perlin noise :( but for normal benching and gaming, high overclocks should be ok.
Thanks for the explanation :)
So what do you have your power slider set to?
Also I just checked and I am using version 1 of 3D mark 11 so I have downloaded the latest 1.1 version to see if this changes anything.
I managed to sort Heaven out I run it from the Heaven d3d11.bat file and it runs

what are you using to clock?
afterburner ?
For benching yeah, afterburner. But i just use CCC's 840/1325 for 24/7 as it has powerplay, just until i can flash the bios with higher clocks (and hopefully voltage).

Was quite chilly in my room tonight, must've been sub 20c. Anyway, i stuck GPU fan to 70%:

Is DarkSiders work for you with OC at CPU and vga ?
Yesterday was the first time when i lunched Dark Siders on my new 6950 and it BSOD after a while with different errors like APC Index mismatch, Page fault in non paged area , etc ... I have to remove all overclock (CPU or vga) to make the game not crash.Is kinda weird i have the 940BE oced for over a year or so and no other game gave me this problems.I thought at first that the 6950 drivers were the culprit because they were buggy...
From performance point of view i got some problems..The game is fluently in general but have 1s freezes at regular time intervals..More like stalker COP.I have 4gb ram and 2gb VRAM.The rig is pretty balanced..My W7 x64 installation is pretty old..Should i try to a fresh OS install ?
Page fault in non paged area sounds like a memory/RAM BSOD. Someone else on here had problems with their overclock after upgrading to a 6970, they had to re overclock and increase volts slightly. That's what i would recommend. What was your previous graphics card?
I've played some stalker and i've had none of the freezing problems you describe. Although i did have similar problems with HAWX, but that was after installing the 1.2 patch, kept freezing for 5 secs every minute.
Reinstall of OS sounds good, that's if it's not too much trouble.
Got my Sapphire 6950 running stable at the CCC limits.
The version of AB I used with my old 460 won't go past the CCC limits, so I'll see if it's the latest version.
http://i89.photobucket.com/albums/k2...970flash-1.jpg
Flashed mine.
OCCT GPU rock solid @ 890/1450 with modded 6950, auto fan profile. Haven't tried higher on the mem b/c of CCC limits.
Games and benchies work fine up to 915 but OCCT detects errors so I backed it down for everyday gaming use. Still, this card has incredible value.
Stock
800 GPU
1250 Mem
1408 Shaders
Modded + OC
890 GPU (11% increase)
1450 Mem (16% increase)
1536 Shaders
Heaven FPS increase (DX11) b/t stock and modded = 14%
Can someone give me all the dimensions for hd6950. (L x W x H)
Sorry for my post, i want to buy one and do not know if enter into the case.
Flashed Gigabyte doing 950/1450, no artifacts that i could see. Only thing missing now is a working soft allowing over-voltage.
This is my highest stable OC so far. I cant waiiiiiit to throw some volts at this thing.

About to do some benches with these clocks, then see the max I can bench at.
http://i89.photobucket.com/albums/k2...70920-1420.jpg
6950 flashed to 6970 running 920/1420
We should set a standard to unigine settings so we arent all posting with different settings...imo. I think we should max the summabish out 8xAA 16xAF.
No, I think
1920 x 1080
4xaa
16xaf
Normal tesselation
just do not want anyone to open the case and put a meter on the video card?
XFX 6950 flashed to a 6970.
I hit a wall at 905mhz on the core speed, it trips out 3DMark11 on the first run regardless of the power slider setting but will run at 900mhz on stock power slide setting over several runs. I can get the memory running at the CCC max of 1450 without any trouble.
So:-
Core 800 to 900mhz increase (12.5%)
RAM 1250 to 1450mhz increase (16%)
Temps are pretty good, topped out at 92C using furmark so I have leeway for a voltage increase and hopefully a few more percent.
Recommend 1680x1050 because I can't go up that high!
Here are my settings:
DirectX 11
Shaders = high
Tessellation (DX11) = Normal
AF = 8
AA = 4
Full screen
1680x1050
Vysnc = on (special menu setting) + D3D-enabled triple buffering
Driver = CAT 10.12hf
Min 20.7
Max 61.3
Avg 46.5
Score 1172
OCCT Settings:
Test type: Infinite
Res: 1024x768, 60Hz
Shader complexity: Default (0)
Fullscreen: No
Error check: Yes
6950 unlocked to 6970
