W00t! Awesome! Good to see you found a solution.
I'm happy to report that I'm Prime95 stable at 3.6 GHz (450 x 8) with a BIOS setting of 1.46875 vcore (1.424 in CPU-z). 54C load, 25C idle.
Memory (PC2 6400) is synced so it's overclocked to 900 MHz at 2.2 volts (within it's rated voltage). Timings are 5-6-6-21 2T so I'm goign to work on getting these tightened up a little.
FSB and MCH haven't been raised. I figure I could go further with this, but I'm satisfied with 3.6 GHz, which was my target (although I may try to get it higher later...)
- Get a big box fan
- Open case
- Point box fan towards case and turn on box fan
- Put vcore at 1.525v
- Put MCH, FSB +.3v
- Put DDRv +.5v
- OC Like MAD!
- See if you can run 535FSB
- See if you can run 540FSB to beat me.
I seem to be stuck at 2.66ghz. Currently i set the fbs to 333 mutliplier is 8, ram mutiplier is 2.0, volt 1.3625 , ram set to 4-4-4-12, ram volt +.4 If i go any higher then 333 the system will just double post and it sets everything back to stock. I've tried doing +.2 for fbs volt and mch +.1. what I want to end up with is 2.8ghz (7 * 400) so i can get my ram running at 800ghz. I tried the 7*400 and system double posts and resets as well.
