Crossfire Question

post #1 of 2
Thread Starter 
So yeah. If you look at my sig, you'll see I have 2 5870s listed in crossfire. Now, I DO have those 5870s, but I am currently waiting on my 10cm crossfire bridge from ASUS due to some unfortunate incidents involving my cat and the one that came with my motherboard...ANYWAY. One of the cards I have is an XFX 5870 XXX (overclocked edition). Would you recommend flashing one of the cards bios so it matches the other? I heard somewhere that if the cards aren't the same in clocks or whatever, it doesn't work well?

Excuse my nubbishness on the subject, I've only ever run crossfire on identical cards (2x4870 512mb, 2xHD2900XT 512mb), so I'm sort of new to the different clock scenario.

Oh yeah, and would it HURT to flash the diamond to the same bios as the XFX? I'm using the XFX right now and it's extremely stable. Both are 100% reference cards as well.

Thoughts?

I believe the highest clock card underclocks it self once it becomes a slave in crossfire. I don't know about stability though.
