295x2.

Having problems running 2 of these cards in crossfire (4 GPU's) on W7.

Each card works fine on it's own but soon as the other card goes in , nothing , won't even boot.

Any ideas guys ?

Edit...got into BIOS getting ERROR: Insufficient PCI Resources Detected ?

What way? More memory?

Nah...went into BIOS and started with changing GEN4 to GEN 2 but later put it back to GEN4 so don't think that was the problem.

I think you have to disable everything (sound,ethernet, internal GPU etc.) as well as setting above 4G  decoding and disabling re bar .

I have a Tachyon....I can send you profile if you have same board.

It was fun and much more fun than running a 4090 (plug and play) ?

Worst GPU problem I have ever had

AMD eh lmao

nice! and gen3 working looks great

kinda weird that you had those issue. My tachyon always worked great w/o setting any manually in bios.
