BF2S Forums What besides RAM prob can cause complete system lockups while gaming?

Videocard overheating? It is "superclocked", but I don't think that should be a problem.

Try lowering the video settings and clocking the videocard slower and then play some games and see if that does anything.

Rivatuner will tell you everything about your vid card.  Have you tried running the CPU @ stock and see if it does it then too?  There is also the possibilty your PSU is going bad or underpowere (not listed in sig so I don't know what it is)

Like Jaymz said, Riva Tuner is a great program (though I just use the ATi Catalyst Control center, but you can't use that with nVidia cards I don't think).

Try lowering the clock and upping the fan speed (can do this through Riva Tuner), as well as lowering your settings, and play some games. If things are fine, raise the clock a little and put the fan speed back to normal, and raise your video settings little by little. Keep going until you find what settings screw you up.

I suggest first just lowering your video settings to the absolute lowest without doing anything to clocks. If it runs fine, then put your settings back up and lower the clock stuff. Then just keep raising your clocks back up until it starts crashing again. Once it does, just go back down a little bit.

I'm really leaning towards the clock speeds since an 8800 GT should have no problems whatsoever playing any of the games out there.

Everest is also good at telling temperatures for the whole system. It might be your CPU overheating.

Update.  My psu is a 680 Aspire psu...

ok, pc runs great w. three gigs of ram, add the fourth and bam, thats when i get teh lock ups.  I either have a bad stick or my mobo doesnt like four gigs.  either way somethign is gonna get rma'd....

BTW:  i took the overclock off teh cpu a few weeks ago, not it.  it was stable, lol i forgot i already have rivatuna... it says gpu core is 40C?? kinda cool for a G92 8800GT?? seeing as its single slot active cooled... anyways, gonna have corsair RMA this stick, if i have more issues, gonna rma the board through EVGA.

Couldn't you just try different variations of RAM to see if one stick, one slot, or the whole motherboard is broken?

Good job. Hopefully everything gets fixed

i have vista 64 bit... in op.... supports four gigs.

Update: 

So someone suggested that i up my voltage to 2.2v from 2.1 with all four gigs.  running stable now.. Why would i need to up my voltage for more memory?? Can someone explain how RAM voltage works and why it needs to be increased for more ram?  I found the tips on the EVGA forums for the 680i board and from a fellow clan member who has similar Corsair ram. 

I actually have five of these DIMMS ( 1 gb modules), last time I actually had bad ram, i sent Corsair one DIMM and they sent me a matched pair in return.  So I have one extra that i know is good.  Its my fourth stick right now (slot 4) running stable at 2.2v 4-4-4-12.

Im not as well versed in this as others, but voltage plays a major part in RAM stability. Sometimes RAM doesnt come with the right timings set, and you have to manually set them right.

Pretty much right. That's what I'd have suggested (either that or loosening the timings or lowering the memory frequency - always loosen everything up if you start having problems). Higher voltage makes stuff more stable - an easy (but not completely accurate) way of looking at it is thinking of voltage as the amplitude of the signal transitions from positive to negative voltage take time and running at higher voltages makes the transition time from an unambiguous +ve or -ve signal faster and hence more likely to provide a correct answer when sampled at higher frequencies. Ambiguity make the system crash, because if it (the system can't tell if it's reading a 1 or a 0 then it has to guess and if it gets it wrong, you get unpredictable crashing.

Make sense?

karma good Sir.
