Intel HD3000 overclocking results - Page 2

post #11 of 13
hi
Please introduce a program to overclock my hp laptop graphics.
I just got my intel hd 3000 graphics

Hello
I would like to know if it is possible increase the iGPU offset voltage in order to reach higher clock speeds and make it more stable...
Using aisuite ii turbo v , I could get it auto tuned to max 1600Mhz with an offset voltage of 0.250v

Please let me know
Thank You

Hi,
What I heard was that the voltage limit for the iGPU is the same as for the CPU so 1.52V. I would assume that increasing the offset would improve improve the stability at higher frequencies, but you would have to test it for yourself while keeping temps and voltages within their limits.
I have noticed that the possible iGPU overclock is very related to the CPU frequency (higher cpu oc => higher iGPU oc), so I would advise overclocking the cpu first before starting on the gpu. With a i5-2500k CPU @ 4.5 GHz the HD3000 can be overclock to about 1.8/1.9 GHz without increasing the offset. By using a higher offset voltage I believe you can push it quit a lot further, but I have no source to confirm this. Do know that as you're increasing the frequency of the iGPU, also the voltage increases! (since in offset mode the voltage depends on the frequency).
Cheers

EDIT: Oh right as is pointed out in the OP the iGPU oc is probably related to the cpu voltage/vCore instead of its frequency.
EDIT2: Ok.. I tried the auto tune option.. remind me to not used it next time. And I would recommend that you don't either. Anyway so I believe the iGPU doesnt have its own voltage setting so the short answer to your question is Yes increasing the vcore helps.. I will go and sleep now.
