Quick Spec: Core i7-920, Asus P6T mobo This started happening a few of weeks ago when a sudden power outage caused my computer to crash. I lost my OC settings that, up until that point, had been rock solid stable. I guess the computer gods were afraid of my progress so they had to throw me a curve ball. Anyways, lately the computer has been behaving quite strangely. I had to reset all of my settings in BIOS but this time I saved them. The computer is overclocked to 4Ghz as before with a x20 ratio and has 6GB DDR3 RAM. The memory is set to DDR3-1600 but always reads back as 800mhz. Is that correct? I also noticed that the data rate was 1T and the DRAM ratio is 2:8, the timings are (stock) 6-8-6-24 w/ a 1.66v core. I'm pretty sure these were the same settings before the outage ruined everything. So that was all good up until now... I've been playing games without a hitch and now I'm experiencing problems. The system will completely lock up and then BSOD with almost no information. I've checked the PSU ratings and they seem normal and I've already run tests for RAM corruption. One really strange thing that happened was when the system came back online, the POST read that the CPU was overheating @ 75c. From what I understand that's actually quite normal for an i7 chip under load, correct? My cooling system isn't really designed for Nahelem CPUs but it's been doing a good job so far. I was hoping someone could shed some light on the situation because I don't think my settings are 100% correct. I'm supposed to have a 1:1 ratio between the CPU and memory aren't I? Like I said I'm using the stock RAM timings and voltage so I can't think of why it's doing this now. Any help would be extremely appreciated.
