PC as in signature. Vcore at 1.45V. Settings as pic: This is stable overnight on Prime95, max temp about 53 degC. When I try and get the HTT any higher than this it refuses to boot - I can get as far as Windows load up sometimes and it then hangs. Changing Vcore has made no difference. Any suggestions? Have seen some boards with HTT in 300s, mine can't seem to get any where near it. And tried getting the CAS to 2 as per SPD but it hangs on Windows boot. Haven't really fiddled with the memory yet but have it running at 230MHz which doesn't strike me as too bad. Any thoughts / advice welcome, cheers.
