6950 clocks

[easyrider]

New thread purely for 6950 owners.

What are you getting when clocking?

[Oztopher]

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

[Oztopher]

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?

[Gaul]

Nice Gaul Temps?

fan 70%, temp about 65c on 2011

[Oztopher]

I see, i may have to give that a go

[Gaul]

@ ^ = yup

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

[Gaul]

@ ^ = only coz CPU......see i'm only 9550 @ 4 gh

[Elfear]

What are you guys using to bypass the CCC's limits? Afterburner 2.1 beta?

[Oztopher]

@ ^ = only coz CPU......see i'm only 9550 @ 4 gh

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

I'm just using v2.0.0

here q 9550 @ 4.37 GH

[Oztopher]

Haha, nice. Beat my GPU score again

How do you do it?

[Gaul]

@ ^ = easy........ CPU clock........
first only 4 GH, now 4.37 GH, that's ALL

[Oztopher]

Yeah i realised that, but you seem to consistently beat my GPU score Albeit by hardly anything, 0.2fps at most.

[easyrider]

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

[Oztopher]

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?

Heaven doesn't run at all in any of the settings.


Black ops is playing fine though

why are you only getting 15420 in vantage?

[Oztopher]

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?

[easyrider]

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?

[easyrider]

Broke 5k

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.
