e762 4 way, crossfire-x issues

Splave · #1 12-01-2009

Hey guys, I have 4-5770s sitting here next to me. I just cant get them to play nice with the new board.

Using drivers 9.11 off ati sit, fresh install of win7 x86, stock settings.
Installed 3 cards and it only sees 2, no device manager issues. Only 2 cards shown in gpu-z etc.

Is there any magic necessary to get this to work that I am not thinking of?

What do you have it set to on the catalyst software? If I'm not mistaken there is settings in there for tri-crossfire and I can only assume quad-crossfire. This though is if my memory serves me correctly as it has been awhile since I had tri-crossfire going.

You might have to re-install CCC after you install all the cards.
Win7 or CCC was having issues recognizing my cards when I put the
second card in after updating drivers.

go into your bios, under FREQ/VOLTAGE control..... then into "memory feature" please try changing the memory low gap setting.. try each setting.... one of them should help for you.

also the newest bios allows better multi gpu addressing

good call on newest bios

Either that did it or disabling the pci-e jumpers for the slots I wasnt using did. Thanks overclockaholics
