1.3v gpu an mem 1.7v

[aussie-revhead]

Is there an easy way now to get 1.4v vgpu ??

[enkie]

with bios asus unlocked and gpu tweak .

http://www.techpowerup.com/vgabios/1...72.120104.html

but the frequencies do not switch all the time in 2d with this bios .

[MetalRacer]

I'm able to get 1.4v with GPU tweak when running crossfire, but only 1.3v with a single card.

[aussie-revhead]

Are the cards responding to 1.4v and clocks increasing proportionately?

[owikh84]

I am getting bad artifacting, and fan control drops to 50% even when set to 100% all when trying to overclock at all.

bad card time to RMA?

bios is asus, and drivers are the pre certified ones (12.2)

edit: it was the 12.2 pre certified drivers. I also flashed to the MSI bios (link below) as the asus bios has poor performance as Martin said.

This special MSI bios allows my trifire 7970 to bench 3DM11 @ 1300 @ 1.29v, altho artifacts. Gaming is stable at 1.3v.

With Giga stock bios & Asus highest could achieve was 1275 only with whatever voltage.

Thus I think this MSI bios has better vdroop & more stable than the others.

My 7970 BE's just got delivered today. I dont normally OC cards but I may give these a try for some benching. I might give that MSI bios a try even though these run 1000MHz stock, I cant seem to clock them well even at 1.3v. Could be a driver issue, 3dm11 crashes my system when clocked to 1250 on the core.

should b fine as i've flashed this bios onto my 3 cards. Just make sure that u rename it to something simple like msi.rom then force flash using atiflash -f -p 0 msi.rom

[Martin.v.r]

yes ore
atiflash -p -f 0 MSI.100

[donmarkoni]

All "original" BIOS'es which are 128kB have code only in first 64kB. Checked 'em all myself, cause I was intrigued by same question.

[Satanello]

Hi! Guys what should i do to modify the maximum clock in Afterburner panel? I'm @1200-1600 but i want to try better clocks for ram.
Tnx in advance!

Is this bios supposed to force your card to stay at 3d volts and clocks all the time? That's very undesirable.

yes you're right.

Does anyone have a BIOS for the Asus DirectCU II version of the HD 7970 they'd be willing to share?

[dasa]

just uploaded one from HD7970-DC2T-3GD5 with gpu-z to techpowerup
im guessing it will show up on there site
my card can only hit 1200mhz and doesnt have a cutout on the backplate over the vrm like some of the newer ones not that it seems to make a difference

[Andrea deluxe]

sorry but...

Ill have to double check but, the bios I was using that was posted at Kingpin cooling that allows 1.4v did not force the card to stay in 3d mode all the time, the card seemed to operate as normal. It just gave the option to set higher vgu.

[MisterMagoo]

Is anyone playing with XFX BE's and having any luck? Or has anyone flashed BE's and had better luck? They rock stock, but I cant clock these things worth a damn.

[Rattle]

Cool I'd try it lol.

I'm pretty happy with this cards abilities, I can run BF3 at 1.037v at 1000/1425 and gpuz says its .980v lol and I can run 1150/1600 on stock volts, 1.112 in AB and 1.05 or so in gpuz.

OOPS was sposed to quote OCNUB

thanks
