help with gtx 970 overclock

post #1 of 6
Thread Starter 
i've just got my new gtx 970 (evga acx 2.0) and have tried to overclock it, i'm a little confused, i've upped the core clock a little and it should be at 1401mhz, when i run OCCT stress test it only seems to get to 1304mhz as reported by msi afterburner and gpu-z, i've upped the power limit, why is it not going up to the clock i've set?





Edit:

if i use furmark it seems to go up to the correct clock, so what can i error test with as OCCT doesn't seem to go to the correct clock?

What's the actual model of the card, curious if you got the older 29xx cards.

there should be a part number on the barcode of the box

i.e 04G-P4-2978-KR or 04G-P4-3974-KR

If it is the former, then you've most likely hit a wall with the power limit.

yeah its 04G-P4-2974-KR i am getting perfcap "power" in GPU-Z but it doesn't seem to throttle it to much (whilst running heaven) clocks are at core 1400mhz and memory 2000mhz, runs for an hour on heaven with everything up to full, doesn't artifact or anything so i think it's all good

simply you need custom bios with higher TDP limit to avoid throttle at higher clock .. If you'r willing to try custom bios check my Sig thumb.gif
