Dual gpu big headache?

[psychas]

since i have 3870xt in crossfire for week now it gives me headache first it 3 days it was crashing till i removed 1 crossfire bridge in some games it makes some strange visual effects for example in cs:s screen shakes after flash grenade.

So i thought i fixed it worked fine with crysis and quake 4, but today 7pm i had important match in cs:s and i crashed 2 times till i disabled crossfire in end result we lost 13: 17 as i missed 3 rounds.

Does anyone else has some problems with dual gpu or it is just me and my bad luck?

i have 3 gpu two 3870xt and 1 8800gts g92 in other rig should i just sell one 3870xt and put 8800gts back in and in other rig leave one 3870xt?

i might give it one more day but i'm not sure

Second X2 incoming, I may soon sympathise...no problems thus far :|

@ Mud: are you upgrading your PSU? I'm not sure the 620W corsair will handle two 3870X2 cards.

Yes, Thermaltake Toughpower 1200W ordered...the 1000W would've been overkill, but there wasn't much difference in pricing between the two so it made sense to me to over-overkill. Should be pretty efficient at such under-utilisation anyway.

I've read a couple of reviews which show a X2+XT drawing about 530W peak (IIRC), with the other configuration power draw figures and a bit of algebra it looks like the XT draws about 62W and the X2 about 153W.

Will be nice to see results i got a x2 and would not mind putting a single 3870 in my rig also.And like you would mean a new psu so if its not worth the trouble i wont .

Major overkill on the PSU there! lol

850W would have been more than enough.

Yep! I'm a sucker for headroom, energy efficiency (says the guy who is going to run 2 X2s) and big fans. I'm building the girlfriend a quiet build with an ATX PSU, and I'd rather she under-used my Corsair 620W than buy her a Corsair 450W and sell the 620W for a similar price to the 450W, which keys in nicely for me upgrading. Likewise, an XT costs more than half as much as an X2. I'm sure it's a bad time to buy a graphics card right now, it's just that my justification skills are considerable

Selling my two 3870s...can't be arsed with em anymore. Gone back to Nvidia...they've always worked fine for me.
