New Bios update for gigabyte HD7950 ! - Page 65

post #641 of 1324
I would like Belkov's opinion. What do u think about me flashing f43 bios on my card which came with f10 bios? If there are any problems I can revert back to f10, right? Since we've got dual bios. I value your opinion.

Im currently on 1100/1575 and i still experience them, however for gaming card is stable in 1135/1630.

This is with the Gigabyte WF3? I'm impressed you can get your memory so high, my computer crashes at 1500Mhz memory. The artifacting disappeared when I upgraded to 13.3 beta drivers, no more of that. I just get really disappointing temperatures. At an intensity of 14 @ 950/1250, I get 65C for my bottom GPU and 85C for my top GPU, frown.gif

I tried spacing them out a bit with some zip ties but you can only go so far, I also changed my side fan from a 230mm to 4x120mm high flow fans. That definitely helped as before I would be ~94C for my top card. I'm thinking about putting in a riser right now though, if I could do that then I Could get them about one slot apart which should be enough to bring temps down significantly for the top card.

Ouch, that mobo is not very well designed for a dual-GPU setup...

What I reached after flashing F43. I can't remember what my score was while running F10. usually I use the "extreme" preset and bench from there. I am running 1.15mV on core, 1100mhz and 1575 on the memory. My AICS score is 84.2%

PC Specs:

MOBO: Gigabyte 990fx-UD3
CPU: AMD FX 8350 (8 core) overclocked to 4.6Ghz
Cooler: CM Seidon 120 water cooler
GPU: Gigabyte HD 7950 3GB (f43 bios)
RAM: 16GB GSkill Sniper running at 1600mhz
PSU: Rosewill hive 750watt modular

Well, you have dual bios option, so i don't think it will be problem to try it. smile.gif If it doesn't work you always can reflash again to your primary bios.

Edit: LOL you did it already...smile.gif

And this is very good score - i need 1.2V. for 1100MHz core - my asics is 58.4. smile.gif

Was able to raise the clock to 1125Mhz and memory to 1600Mhz and benched again. Although this time I reached 70C, whereas before i never went above 65C. Is 70C safe for gaming, or are my settings too demanding? Voltage is still set to 1.15mV
post #647 of 1324


So now I just cant stop benching.. I STILL have not had to touch the voltage!! I actually LOWERD it! Running at 1.125mV and currently running at 1175MHz on the core and 1600 on the RAM. And I have a feeling I could bump it up to 1200 on the core and still have no problems. Currently running at 70C during benching and gaming. That is not too hot is it?

it's not but you can reduce the temp with setting a manual fan profile in afterbuerner.

What do you suggest for a manual fan setting? I just ordered a couple of 120mm fans that blow at 100+CFM and I'll be adding those to the side of my case blowing directly on the GPU and CPU/vrm. hoping that will help quite a bit with temperatures.

Is a 1200/1600 setting on my GPU safe for 24/7 use if my voltage is at 1.125mV and temps at 70-72C?

If it is 1.125 it is safe but watch for your core and VRMs temps. This fans must help - yes, but i ment to higher the % of the fan profile in AB when you are loading your card - this is the easiest way to reduce the temps of your VGA.
