New Bios update for gigabyte HD7950 ! - Page 25

post #241 of 1324
Ok. Thank you. Almost the same with me - i need 1.2v for CCC limits.
post #242 of 1324
My Gigabyte WF3 7950 has an ASIC of 58%. It had F2 BIOS and stock volts on load are 1.088v for up to 1 GHz. On F3 with the 1.25v I can max out CCC core @1200, and 1575 mem, haven't tried higher mem. Ran Unigine Heaven at defaults with Tessellation at normal and core maxed at 65 and VRMs at 79/82 with fan at 40%.

I don't game. I crunch on WCG for Cancer on my GPU.

This is VGA artefacts or bug or erros from ati catalyst 12.11?
I decreases in maximum all clocks, core and memory, this bug kept happening and only in Farcry 3, other games like Battlefield 3 does not happen.
What a hell is this?

Resolution 1920x1200
Phenom II 945 @ 3400Mhz
Gigabyte Windforce 3 OC HD7950 3GB 1100/1500
Dell U2711
All Settings Ultra 0x MSAA

I can't start the video but if the issues appear only with Far Cry it is almost 100% sure it's a driver problem. With 12.10 drivers i had massive appearance of artifacts in Assassin's Creed 3 only. I changed the drivers and the artifacts disappear.

Really dud hitting anywhere in the 70s is completely fine for the card. I am using the stock 1.238v the bios gives me for my 1200mhz on the core and use 1.225v before this bios.

Any Idea why mine is running stock at 1.25 V and the other at 1.112v? This is what AB is showing in BF3,

Because of your bios version. There are different bios versions. I presume that your default core clock is 1000MHz. Just read this thread.

Thanks for writing down the exact values. My memory was hazy and I wasn't by the PC.

This should be the fracking default setting in AB. Maybe we can report it to msi? Btw, I wonder if trixx or gputweak do this automatically?

Hey guys, i just made an account so i could ask you something, I got my gigabyte 7950 yesterday and it seems like a terrible OCer (crashes @ 1000/1350 @ stcok) so i want to update my bios. The file from the Gigabyte website (the F43 bios) is called R795W3GD.F43 Do i rename this file to something.bin, and execute atiflash.exe -f -p 0 something.bin, or do i leave it like this and go atiflash.exe -f -p 0 something.bin Thanks !

As a side note, GPU-Z shows my vcore voltage @ 1.15 while it is set in Trixxx @ 1.2, is this normal ?

Hello! I just bought a Gigabyte windforce 3 and it came with the odd bios that has issues. The bios that it came with is the FZ1 bios, which a few users seem to have in this thread. It comes stock 1000mhz core clock, 1250 memory clock. When it is on desktop it stays @.949v, which is perfectly acceptable. But for some odd reason, it is completely voltage locked @1.250v when powered up (I can force other voltages through MSI afterburner, but if I shutdown/sleep my PC it changes back to 1.250v). Another thing that is stranger, I can overclock the coreclock quite easily, but if I dare up the memory clock beyond 1250mhz, the voltage becomes locked at 1.250v and will stay locked there (unless I change the voltage manually anytime I do anything...).

It just seems strange that I cannot under any circumstances overclock the Memory Clock without the voltage locking @1.250v, whereas I can up the coreclock and not have a single issue. Should I attempt to flash the bios to something else, should I keep the memory clock @1250mhz (I use 1080p monitor)? If I keep the memory clock @1250mhz, how much will my frames be affected? Or should I just overclock the memory and have it run constantly @1.250v? Sorry for a lot of questions, the problems I am having just seem like they shouldn't be a problem...

Also, my temperatures are pretty good, @1050mhz and 1250mhz memory clock the VRAM doesn't go above 60c and the GPU stays anywhere from 45-55c (depends on the game). Furmark, OCCT and such will push the GPU temps to around 65c.

Just type "atiflash -p 0 R795W3GD.F43".

1.2 is the max voltage so in idle it is normal to be even lesser.
