I have been having some trouble with my new SLI system, and have looked around and not found anything like this problem...
Ill start off with my system:
Case: Antec Nine-Hundred
CPU: Intel Core i5 Lynnfield 2.66 Ghz Quad
Motherboard: MSI P55-GD80 LGA 1156
RAM: 8GB Corsair XMS3 DDR3 1600 (PC3 12800) (4 x 2GB sticks)
Power Supply: Corsair CMPSU-850TX 850W (SLI Ready)
Graphics Card: 2 x XFX 9800 GTX Black Edition PVT98FYDBU 512MB 256-Bit GDDR3
OS: Windos 7 Ultimate - 64bit
then some opticals, hard drives, and some speakers...
I am running two cards in SLI, and when I am browsing around windows, opening folders, surfing the web, and watching movies in WMP, everything is fine. However, as soon as I open an application (and I am not sure of the correlation between these, other than they all are *outside* of the regular "windows" interface), i get some strange blue flashing lights almost like every frame displayed has a second blue-tinted shadow on it...here are the programs so far that I have seen this in:
3d Mark 06
3d Mark Vantage
Call of Duty 4
If anyone has any idea on what is causing this, I would love to hear it, and before you ask, yes, I have connected the SLI bridge, installed proper drivers, and everything else...also these cards are IDENTICAL, so there shouldnt be any issue...right?
So after troubleshooting for the past couple of weeks here, I finally identified a problem. I took out both cards and found a small piece of dust in one of the PCI Express 2.0 connectors that was wedged in and didnt get blown out during any of the cleanings. I cleared it out, and reconnected everything, but now there is another issue...
I feel as though it might be a heat issue, but before I go spend a ton of money on heatsinks and fans, I would like to know what you all think...
So I am playing modern warfare, and its running great in SLI, High settings, 4xAA, 1920x1080. For about 5-10 minutes it works great, then it started to slow down and become significantly jerky. This is consistently what happens, as it works for a few minutes then becomes unplayable. This does NOT happen in non-SLI, and does NOT happen on lower graphics settings...(setting AA off it works fine)...
yes, older games such as Warcraft III work fine (i dont think AA even applies). I am thinking it could be a thermal/heat issue...is this a likely situation? Also, how would I go about cooling my video card? It already has a fan on it, and I dont have a lot of room for one of those GPU coolers that take up a PCI slot...
