Finally got 550 FSB, but had to stop going further due to water pump stopping and PC repeadtedly shutting off !

I'm assuming it's the dodgy 12v atx connector I thought I'd fixed

Got to the login screen for 557, but then I started getting the shutdowns...

I'm giving the board a rest tonight after that little blast which turned out quite risky, so I'm gonna tighten up 500x9 which I've now got stable.

PS, can you run lower than PL9 on 1:1 at 500FSB UD3P? Any recommendations for the drive strength at this speed too?
