For those who still confuse about the new rebadged gpu.

HD7690M XT = HD6770M
HD7690M = HD6750M
HD7670M = HD6650M
HD7470M = HD6490M

Is it possible to do an clock on this card without raising the voltage?

yes.
start overclock slowly. if you want first memory after core and do maybe 5times run sm tests on 3dmark 06. only sm test to find for artifacts. if sone red bleeps appear on screen press esc and downclock
this method i think its better than artifact scanner from att and other

Right now, my stable OCs to be able to play BF3 are 780/850. Over that (800/850) BF3 crashes right at launch. Do I need to increase voltage to OC over 800/850?

Also, the video capture set to 1/2 frame on MSI Afterburner is in black and white and also has the right margin overlap on the left margin from the left. Google results say it is probably a GPU driver issues, but I am running the latest HP drivers.

I have run bf3 with 825 and 950 clocks without issues, except of the crashes I have with any clocks I tried before.

And have to say that latest hp drivers are probaably the most stable but performance is not as good as with newest ones, about 15-20%

OC 825/950 seems to be the right one, haven't had any issues with BF3 or youtube

825/950 without any voltage raise?

Again, thanks guys.

stock voltage

OC/D to 825/950 now on stock voltage. The temp never passes 72 on the GPU sensors and the CPU is laying below 80. How can it be that my FPS went down (BF3)? Still the same GFX settings, same drivers, etc..

Im now getting FPSs aorund 30-40 on everything low..
