7970 CrossX Gigabyte GA-Z68X-UD3P-B3 (rev. 1.0)

[BuddhaCube]

Alright then guys, I need some help. I sold my old computer to to my brother and he is trying to run 2 7970's in crossfire on a

GA-Z68X-UD3P-B3 (rev. 1.0)

with the latest (U1F) UEFI BIOS installed. It is a beta BIOS.
Neither of us have set up Crossfire before, so we are stumped.

Also, when both cards are plugged in, the BIOS doesn't work. Take the second card out, bios runs just fine.

Specs:
i5 2500k
6gb ram
2 7970s
1tb wd black
windows 7 64 bit
750w Corsair TX


We think that either it's the PSU holding it back, or the BETA bios I installed, but we can't get Crossfire to work at all, yes both cards have power and fans are spinning. And the computer has a fresh Windows install on it. I know an 800w or more PSU is recommended for CF 7970's, but someone said we MIGHT be okay with the 750w TX. Can anyone confirm or deny any of this? Thanks!

You checked in CCC that xfire is enabled?

750watts is fine. If your bios works with only one card then either the bios is bugged or one of the cards is bricked.

We couldn't find any cx option at all in CCC.

Cards both work, I had one in my new one, and he had the other in his old one, and they both work fine.

Must be the BETA bios.

I think I'm going to try rolling back the bios, does anyone know how to do this? Thanks again.

I'm running 2500k@4.6 plus 2x7970@1200/1800and power draw from wall peaked at 691W

In CCC open the performance tab, the XFire option is in there mate.

The option isn't there, I don't think it shows up until the other card is recognized? Confirm/deny?

 

[NeverBackDown]

Silly question but did you guys ever use a Xfire bridge?

 

[Excalabur50]

Also make sure that the AMD drivers are the right and latest as sometimes they wont install properly check in CCC that they are correct if not uninstall them with DDU in safe mode reinstall and see if x-fire works then also you may have a dodgy bridge see if you can get another one as one of mine was faulty out of the box

 

[BuddhaCube]

Silly question but did you guys ever use a Xfire bridge?

We have 2 xf bridges, and both of them are hooked up since the cards have 2 connectors each. Is only one needed?

 

[NeverBackDown]

Ya only one is needed. Only use two if you are running 3 way or 4 way Xfire.

 

[Excalabur50]

Yes only use one bridge and use the fingers closest to the bracket

 

[BuddhaCube]

I'll try that, but for some reason we still cant find the Cross fire option in there.

Roll back to the old bios type, the Beta UEFI bioses for Gigabytes are shit. I upgraded mine and you lose all kinds of functions.

Theres a guide on roll back here:

[SeekaX]

Oh boy.
Never run anything with beta in the name for anything other than testing purposes and even then only if you can afford it. Roll back to a normal BIOS and maybe check how to setup crossfire before you do it and possibly brick your system.

Okay, so I put the EFI2AWD and Z68XUD3P.F8 on it, but when I f12 to get to the boot menu, I get a message saying "Remove disks or other media, press any key to restart"

I've set the boot priority to the flash drive, and it still says the same message.

Any help??

Read the instructions again? You can do it in Windows.

If you dont have windows installed yet, then you need to create the bootable USB using Rufus or similar, then copy the back to award and the bios files

Messing with the BIOS from within the OS is never a good idea.

These days with dual bioses, I don't agree, unless you can give a good reason why there is vastly more risk doing this in windows rather than a bootable dos USB?

Anyway, the option is there to do it from a bootable usb if he isnt comfortable doing it from Windows.

Is the chance of bricking your partition a good enough reason?
