PCI-E compatiblity on M2A-MVP 480X

post #1 of 8
Thread Starter 
Alright so my motherboard has two PCI-E 16X slots, but when run in crossfire mode are only 8x each. My question is, does this 8x-8x only apply to crossfire, or when any other card is the in the slot, I was thinking of doing a non-video card in the second slot and didn't want to hinder my GPU's performance by lowering it's speed to 8x.

If its like the M2N-SLI then a single card will run at full x16, but dual cards will run at x8 each, so its like the entire bus has x16 versus each slot having dedicated bandwidth... but again, thats tentative.

I realize that, which is why I said if its LIKE the m2n-sli. If you throw one card it runs at full speed, but if you throw two, then its half speed. I was suggesting that perhaps this board operated a similar way with crossfire....

M2A-MVP, oh boy, Blue slot at the bottom is the 16x, black one is 8x, Vcore is not changable (says in the manual too) if u want full 16x, put the switch card in the black slot, that will block up the 2nd PCIE and give the blue slot FULL 16x

EDIT: I am that struggled M2A dude, did almost everything possible with that board, got more questions just ask me

Yea, this board is horrible, ahaha. A new motherboard/cpu (going intel) jumped from the bottom of my upgrades list to the top in recent weeks.

Anyway, thank you for the help.
