Spontaneous Reboots

[thehum]

I had my C2D e6300 at 3.15ghz without much of a problem for the past few days. Then today I installed some software and my system just rebooted randomly. So I lowered the clock to 2.8ghz but after an hour of CoD2 my system rebooted again. I've had my system go through 10 hours of orthos at 3.15ghz before. Only had this problem today. I know overclocking can cause all kinds of complications, and spontaneous reboots can be one of them. So right now my settings are as follows:

6300@2.8ghz (400mhz FSB)-1.35volts
Corsair 2gb DDR2 CM2X1024-6400C4 @ 800mhz
All on my DS3.

For some reason my timings change with my overclocks. right now it's at 5-5-5-18 even though it's rated at 4-4-4-12. Is there a way to change the timings and should I?
I know upping the CPU voltage and ease instability but what about the memory voltage? It's running at 6400 speed right now and reboots every once in a while still. Could the southbridge be overheating?

Anyone else have similar problems? suggestions? Thanks

I knew before I even came in here that you'd be using a DS3. That board is getting some amazing overclocks, but more and more funny quirks are showing up every day. I'd be willing to be it's your motherboard.

Is it giving you the "This system has recovered from a serious error" screen when Windows comes back up? If it is, these are actually BSODs that your system is instantly rebooting after.

What other problems have others had with the DS3?

nope no BSOD or system has recovered error on startup. It's as if someone hit the hard reset button. The power shuts off and on again. Although it hasn't happened since yesterday so far.
