hello everyone - so I've done searches on this forum and all over the internet and I haven't been able to find anyone with the same problem as I have. When my computer is under moderate load, it just completely shuts off and reboots without warning. I've done a lot of tests using Prime95, and all signs point towards it being my RAM causing the issue. So, instead of RMA, I bought another set of the same sticks from newegg, and then planned to RMA my other sticks which I thought were my defective sticks after I got the new ones from NewEgg. WRONG - problem persists even with new sticks. However, with the newer sticks, the computer doesn't seem to reboot as quickly as with the other sticks. Here are the facts/things I've done:
1. When using Prime95, using the "Small FFTs" test, my system does not crash or reboot, EVER. 100% stable during this test. I'm overclocked to 4.5GHz @ 1.33V on the CPU.
2. When using Prime95, using the "Blend" test, which says it "tests some of everything, lots of RAM tested" with my first set of sticks it rebooted immediately. With my new set of sticks, it takes about 2 minutes, then finally it reboots.
3. In my BIOS, I've tried setting all of the times manually, 9-9-9-24. Set the voltage to 1.5V. Changed my "A.I. Overclock Tuner" to X.M.P. as I read to do here in these forums. None of this has made any difference. It still reboots without warning. I've actually noticed that when I set the timings to 9-9-9-24 that it would reboot QUICKER, so I set them back to Auto and it doesn't happen quite as fast on Auto.
4. The game I play the most is Flight Simulator X. I usually can't have a whole session without at least one shut down and reboot. I've noticed however, that if I make sure I don't have other things running in the background, such as web browsers or Google Earth in addition to FSX, that it doesn't reboot nearly as often, again leading me to believe this is for sure a RAM issue.
5. I've noticed that on the tool on Windows 7 where it shows your CPU and RAM load, that when it gets over 40% for my RAM, that's where the danger zone is of my computer rebooting. With just running this browser page that I have opened right now, it's at 23%. Doesn't allow me to run much more
6. When taking my overclock off, bringing the CPU back to 3.4GHz, it takes much longer to shut off, but ultimately it still shuts off. Takes about 10 minutes vs 2 minutes at 4.5GHz or with my first set, it didn't even take one second.
Here are the specs:
ASUS P8P67 Deluxe Rev 3.0 motherboard
Intel i7 2600k
NVIDIA GeForce GTX580
Seasonic 750W PSU
g.skill ripjaws F3-12800CL9D 8GB
BIOS Version 2103
Windows 7 64 bit
One other note - my brother has almost the exact same computer, except he has I think a NVIDIA GeForce GTX560 and not as big of a power supply. He has no problems whatsoever, and also plays Flight Simulator X a lot. He didn't even select any settings for the RAM in the BIOS. He's also overclocked to 4.6GHz, stable with no problems.
Thanks in advance for the help.
