Overclocking the HIS HD 6950!

post #1 of 8
Thread Starter 
I'm trying my hand at overclocking my HIS HD 6950. I've got all the voltage and stuff unlocked in MSI Afterburner and I'm ready to go.

Right now it's at 880mhz core clock, at 1.175V and seems pretty stable. I'll try up the speed a bit.

Well..
You can dump your BIOS with GPU-z..Save your original BIOS in several places..
Then edit it with Radeon Bios editor..
Then Flash the modded BIOS with ATIFlash.
You'll need a bootable DOS Flash drive with ATIflash on it.

All you really have to do is open your BIOS..go to the last tab in RBE..and extend the Overclocking range (use the lower method)..then reflash your VBIOS.

Ok now that I can start to overclock this thing, any thoughts on where I should start? Will I need to overvolt it to get 880-900mhz?

It'll probably do that on stock

I tried with Minecraft and it came up with the "Video driver has crashed and recovered successfully" so I up-ed it to 1.175V and it seems stable now, I'm testing with Furmark but that doesn't seem to put it under full load frown.gif

I've got her up to 890mhz. I'll try 900mhz tomorrow, I just hope that voltage doesn't need to go any higher.

Well it seems that running it through a tress test is useless, cause after about 10 minutes of being on the desktop it froze up.

I've now noticed I can't even get it to the normal 840mhz, only to 820mhz? mad.gif
