Thats not anything to do with its bios, is it? Isnt it the hardware? Like... "non-laser cut" 7950s?

how much higher are your 7950 overclocks with the 7970 pcb compared to other 7950 cards with just the 7950 pcb?

Having a 7970_PCB may help w/ o/c but ultimately it's the chip.

I know it depends on the chip and card. My question was aimed at average clocks. Most of you have followed the 7950 threads and have an idea of what people are hitting with the different PCB cards

I've had ~9 MSI 7950 TFIIIs -- all but one were 6+8pin pci-e. They all hit 1100 core minimum. 3 hit 1200 core (including the 6+6pin card). The rest overclocked somewhere in-between.

Why have you gone through 9?

And how's the coil whine on these cards?

Only one had coil whine -- the rest have been ok. Some needed TIM replacement. It's just a hobby -- bought them / used them for a bit / then sold them (actually still have 4). I have some gtx670s that I'm using atm. thumb.gif

Does the msi 7950 twin froze allow memory voltage changes with software?

What is stock core and member voltage?

Yes, AB allows for memory voltage -- default = 1.600mV

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