question about pcie slots for crossfire

post #1 of 7
Thread Starter 
Hi all. So my mb has 5 full length pcie slots, and msi says to use the first and fifth slots when cf since they both are x16 and others are x8. but i'm wondering if i can use the first and third slots to cf because the fifth slot blocks the only pci slot which im using for sound card. the manual doesnt say this, i think it should work but they both will be running at x8. Have you guys tried this?

at 1080p and below you will not notice a performace diffrence between x16 and x8 so whatever fits you better feel free to use!

Good Luck!

Thanks, I know the difference between x8 and x16 is very minimal. I'm just wondering if I can use slots 1 and 3 to cf, or will the board restricts me to use only 1 and 5 when two cards are installed?

btw you brought up another question, I'm actually using 1920X1200, will i notice the difference?

you won't notice any difference either way, and there is no reason you shouldn't be able to use the 1st and 3rd slots

5850's cannot fully saturate an 8x lane. So you'll be fine.
