If you have not played any other games using SLI, perhaps you should before deciding it's a hardware problem instead of a Morrowind-using-SLI issue.

I beat doom 3 using SLI, played maybe 3-4 hours of quake 4 and fear with it too. Morrowind is the only game that has caused any problems that appear to be power related. I'm still waiting on a replay from xfx/ocz... but so far with a single card I've played like 12 hours with no problems.

i have the same psu and u can dial in the correct rails...
measure the rails on load and dial them as exact as you can...
google up on how to check the voltage rails..
but ill just give u a tip[... use the 24pin conector to read em
trust me ,. do this as i am pretty sure ur prob is power

I'd just as soon buy a new power supply rather than waste my time doing that...

One last time!

According to nVidia, it takes 30 amps to run both those cards at once and the 520 watt OCZ Powerstream is rated at 33 amps on the = 12 volt rails total. this leaves 3 amps left over to run everything else. It may not be big enough.

i agree... u might wanna get a stronger psu^^

Well I mailed OCZ and they told me to take out the ps connector going to my motherboard (the one that goes next to the vid card, it had fans chained on it as well) and replace it with the vga/hdd one. They also said my 12v rail might be low and that I might want to raise it but I think its ok, its at about 12.16 according to the bios. Anyways I played oblivion for about 3 hours, no crashes or anything, that mighta done it. I'll have to test more.

never trust software volt monitors. always check volts with a multimeter.
