Haven't tried in BC2 yet.. But so far so good

i'v noticed the second GPU always runs hotter i have 2 HD2600XTs in crossfire and the second one runs hotter. I wonder why.

I forgot to plug in the power cable to a 4850 I use to have. Well... I did it while it was running e-e oops

Also it is because of heat and airflow. The way xfire works is it is from bottom to top. So card is slot one is actually card 3.

I had 2 5770s in xfire and 1 card was always 4-5C hotter than the other and that card was the one above the card on the bottom.

So the faster card goes on bottom?

What


The top card runs hotter because heat rises, and it's outputting the display, so it's always doing some type of rendering.

My bottom card runs hotter, i noticed the same thing for some one else in another thread. He is saying the bottom most card is the primary, is this true?

There's an order that the MB checks for primary display in, but then the primary device is whichever has the lcds connected to it.
