I powered the PC off, took the PSU off and then switched 2 BIOS2. Then booted up, turned off and switched 2 BIOS1. But it dident seem to work I think. Values in CATA is still the same. Might need 2 do a new driver install? tongue.gif

Anyone?

What does that have to do with anything? My point is you don't need a stable 1300MHz OC to get decent frames with a 7970 unless you are running eyefinity. At least that's my opinion.

Guys, I'd like a little later to get a second 7950, but check my M/B's specifications about the 2 PCIe slots:

1 x PCIe 2.0 x16
1 x PCIe 2.0 x16 (x4 mode, black)

So, the second is gonna run at x4 mode... Do you think it's not worth getting a second card without a new M/B?

There will be some bottleneck, but nothing major.
It also depends on resolution.

I'm tempted to OCjing memmory even further by incresing voltage. But i have a stock 1 fan cooler so i dont know.
I have a question tho. My 1 fan cooler seems to cover Vram also. But accelero extreme covers only GPU. Whats with that? I mean according to logic vrms should be off the charts with other coolers? Or are some passive heatsinks enough to OC memmory?

is the max volt will be 1.212 ?

1.095 +125mv=1.212

Actually like i said i have ~+175mV

My stock voltage is .993V. I have one fan sapphire card. I presume the lower voltage is due to weaker fan and lower stock core(810).

@Sena, @Ken, thank you guys! I started digging the issue, and I think I'll proceed, eventually. Later of course, as I said when the prices will drop a little and drivers issues will be sorted out. So, I'll have to deal only with the PCIe lanes.
