Intel HD4000 - what is the highest you OC'd the iGPU?

[rouvio]

Hello all,

I started fiddling with the iGPU settings short ago, and was wondering what are the limits of the iGPU.
What is the highest you OC'd the chip? Voltage?

Thanks.

Well, if nobody finds it - I better start doing it myself!

CPU: 5.2GHz
GPU: 1000/2000
iGPU: 2300 @ 1.525V
MEM: 2600 CL10


for some reason, the HD4000 had a major jump in performance once it is clocked to 2100MHz and above.
the 3DMARK Vantage score is a whole other world between 2000 and 2100 MHz.

The 1.52V for the iGPU, at least for me, seems to be some kind of a barrier.
It works with less or more voltage.. but not stable.

Cool stuff rouvio, you are really rockin on this 3770k! D:

Isn't that Vantage score like super high compared to a high end discrete GPU solution? :S

Thank you buddy!

This run was made with all the "bells & whistles" installed in the system: CPU OC, GPU OC, iGPU OC and finally MEM OC.
Physx was enabled, so as the LUCID MVP technology.

-------------

To compare it to a bench without all the OC and tweaking.. - "native run" :



Amazing change!

Im guessing this is also intels cache technology allowing these synthetics to scale. (As well as the raw frequency of the engine)

It really is!

Could you do a similar gaming test and see how well that fares?
