Okay, some of you may remember me from my other recent General Hardware Thread: http://hardforum.com/showthread.php?t=954064

I'm running the same system, now with only half the RAM in, and I'm having joyous stop errors again.

I just was playing 6 straight hours of GTA: SA as a sort of "I'm bored, and this is a quasi-stability test".

Turns out, it seemed to have worked better than I thought. :p

Now, I'm still getting Windows STOP errors @ 0x8e

And the occasional ntfs.sys error.

However, memtest is now showing errors in different chunks of RAM that's run memtest stable for 8 hours (didn't go for hte full 24 yet, but 4000+ errors before test five, that's a significant change).

I was of the mind that this was a heat related stability issue, but all components are claiming under 40* C, and I can touch them all right after the power's off, and none are anything more than warm to the touch.

So, I just decided to let the system cool for a while (30 minutes) to return to ambient, and memtest is still throwing errors left & right.

Now, this is leading me to believe the PSU could be the root cause. It's a PoS 500W Ultra X-Connect (which did run great for a while, still looks cool, and only cost $30(AR), so even if I turn it into a paperweight or a lamp, I'm okay.)

However, I don't really wanna go order that Enermax 535W SLI ready from the Egg for cheapish, until I'm more certain the cause of the problem.

Here's the twist, since there always has to be one. The 4-pin 12V connector that came with my modular PSU was too short. So, I, and my father, who in a former life was a Naval Electrician, made one up, using two other PSU's 4-pin Molexs, and 18 gauge wire.

There's only one Solder join in the cable, and it's certainly not a cold-spot, but, I can't help but thinking that could be one of the causes.

Educated guesses of what it is/how I should go about testing it more before sending out $130 to the Egg?

I'm gonna swap this gig out for the other Gig after I head back into the IT labs tonight (gotta love RIT), and I'll post back here by 11pm with that stability information.
 
Left it unplugged for two and a half hours, while I ran back to campus, now memtests out fine.

-- EDIT: Died on fourth pass. Other set of DIMMs in now, the first set could have been the inital problem --

--Depreciated: --So, I'm saying it has to be thermal or PSU related.

Anyone have good solid ideas to test for which?

Humbug. I'll leave this running overnight, see how this pair does.
