Hi, hoping someone can give me a bit of advice.
Just over 12 months ago I built the following machine:-
Mobo - Asus maximus Formula x38 (Bios v.1201)
CPU - E8400 + Arctic Freezer 7 Pro
RAM - 4gb Geil Black Dragon GB24GB6400C5DC
GPU - Gigabyte 8800GT Factory overclocked
PSU - Antec NeoPower 650 Blue modular
OS - Windows Vista Home Premium 64 bit
Shortly after building I decided to to try and overclock a bit (my first atempt at doing this). I slowly increased up to where I am today, 3.6GHz (400 x 9). All other BIOS settings, frequencies, volts etc I left set to Auto. Prime95 tests ran fine with CPU-Z reporting temps of about 52/50 @ 100% load. However a few weeks ago I started having problems with long boot times (up to 10 minutes or more) and random BSODs. Reinstalling the OS has cured the long boot times (missing system drivers I think) but I am still getting frequent BSODs when using CPU/RAM intensive apps (runs fine in Windows). Prime95 will not now run at all past a few seconds before the system crashes. I have tried both sticks of RAM independantly in different slots but the result is the same. I have noticed that CPU-Z is reporting that memory is running at 480MHz with a FSB/DRAM ratio of 5:6, I'm pretty sure that this used to read 400MHz at 1:1 but I haven't changed anything. The only thing I can think of with my very limited knowledge is to increase voltages manually to CPU and/or RAM, does this make sense or am I barking up te wrong tree?
Any help or suggestions most welcome,
Pete.
