Crossfire Bus Speed

post #1 of 8
Thread Starter 
Hey guys, so I downloaded GPUZ and looked at the bus speeds for both my 6870s. The first one said it was running at 16x. Okay thats normal. The second card said it was only running at 8x. Now I remember a while back i did SLI 9800 GTX cards and it was the same thing. Just making sure its normal right?

If your board supports 16x in the lanes your running them in and Bios reads it
wouldn't worry about it.

Some boards like mine support changing lane slot bandwidth positioning.

Might check.

Later:D

Well, I moved the card down, and discovered the bridge is too short. So I just bought a new one off of ebay at 100mm long, enough to reach over my 4 slots and then some so im happy biggrin.gif

Not sure what you're trying to ask. But I shall recap. I had two video cards. One in the 16x slot, and one in the 8x slot by accident. I now moved it to the second 16x slot on my board, but the crossfire bridge is too short. So i bought a new one and am awaiting it in the mail. Thats all. GPUZ now shows both in 16x slots.

Damn -_- I forgot to check for myself xD ahhh well. Another good thing is that now there is breathing room for my top card, so no harm done! Worth the few bucks so I don't suffocate it lol. Thanks!
