Possible bottleneck?

[Colours]

I was just playing some Far Cry 4 and Shadow of Mordor, my 7950 is OC'd to 1040MHz. In-game with the graphics cranked to Ultra, the GPU load is 99% but the core clock stays at 850MHz?

 

CPU - 8320 4.3GHz/gigabyte 970 board, catalyst omega drivers. Is my CPU holding back the GPU or?

 

edit: I did OC it with afterburner and used afterburner to see the results in-game

Mmmmight be the GPU on this one.

How do you know it's oc'd, check GPUz and afterburner

sorry, forgot to mention I did use afterburner

What is the temperature at load ?

62c on Far Cry 4(ultra/1080p), 66c on furmark(1080p benchmark)

No that's most likely not a bottleneck.

That usually happens when the card starts throttling. Try running heaven or furmark for a while then log the temps.

See if the clock speeds change.

Ok, run furmark at windowed. Bring up afterburner and see how your gpu usage increases and at what point your core clock goes down. Record the temps there and report back. Note run furmark for 15 mins

just running unigine valley and furmark for a few min each, the core clock was jumping from 489/650/940/1040MHz etc. never stayed at 1040 for a bit

Can I see your afterburner settings?

that was  about 4min with furmark 1080p benchmark running

Aha, do this, max out "Power Limit", nothing will go wrong, just max it out and test again

Thanks, that seemed to work! Stayed at a steady 1040MHz the whole time. Cheers

Like wont hurt

 

OK, so the power limit basically allows your card to get more power from the psu. Thats why in Linus's overclocking videos, you see it is always maxed out. 

When you have a good oc but you dont have enough power the gpu Power Throttles

So doing this is not like increasing the voltage? So there is no danger?

Naa this just increase the amount of watts the gpu can pull from the psu
