I'm trying to OC my Q8300 on an Asus P5Q Deluxe, and appear to be hitting a wall with the FSB - at 450.
I've tried tweaking everything. Voltages, straps, even taken down the multi on the CPU. Prime95 fails usually before 20 mins. MemTest is fine, can run that for 30 mins no problem.
I've had my vcore up around 1.36, nb @ 1.42!, fsb termination voltage at 1.4 volts. Basically taken all the voltages as high as I can get them as a form of troubleshooting and I still get a problem.
Yes I've tried loosening my timings. 2x2GB Kingston HyperX 1066 5-5-5-15 (default)
It literally seems that when the FSB is over 450, Prime fails regardless of ANYTHING else.
What else can I change to support the FSB above 450?
I've exhausted Google. I just can't find specific enough help from simply searching.
