ok i have a FEW problems and questions pertaining to the cross-firing of two cards
an xfx 1gb hd 4850
and a gigabyte 512mb hd 4850, both have after market coolers
now for the questions:
does it matter which one i put where? i put the xfx 1gb as primary because it runs hotter, i figure putting it under the cooler card would be dumb
will i have issues with crossfiring these two? i recall reading the xfx card i have is designed around a mobile chip, dont know if that will mess with my configuration
how many bridges do i need to fully optimize cross firing? currently i have only one on it, i have an x38 mobo with pcie 2.0 x16 on both lanes, a hx750 corsair psu
how would i overclock each card individually? should i have crossfire enabled or disabled when i do this?
also im having a few problems... i get jittery in a few games [i have the latest drivers], and when it is enabled, FEAR blacks out... when it ISNT though, fear works perfectly and i also see a performance boost! WTH?also, i see NO performance boost on bfbc2 for steam... =[
i havent done crossfire in a very long time, and although i feel like i can answer these questions, i figure i maybe wrong since im having so many problems... i ran the newer card by itself, and it worked great, and the older gigabyte one ive been using for a few years, never caused me a problem... someone?? anyoneee?? tyyy :
lemme just put my rig info here to prevent further questioning about my rig
e8400 @ 3.6

maximus formula se x38 motherboard
