HD7950 revised with reference HD7970 PCB club - Page 16

post #151 of 847

I recently recieved a Radeon Branded 7950 from AMD at the last OCN LAN.  It has the multiple holes near the back of the card that would indicate a 7970 board.  It only has 2 6-pin connections though.  I don't want to take off the reference cooler but looking at the bottom of the card, it looks to be only 4+1 phases:

The "stock" core voltage varies from chip to chip.

They are usually the same. Some companies have one stock and one overclocked. But with the reference 7970, the main BIOS is write protected.

Afterburner is not allowing me to change the memory voltage.

I can actually move the sliders for the core and memory voltage. The readings show my core voltage changes, but the memory voltage reading is constant at 1.6

GPUz also doesn't show any changes in the memory voltage.

flashed my card with the sapper.rom
but it bricked my card and had to reflash back to the original bios
