Overclocking help with my 2X 3800

[e36Adz]

Ok im attempting to overclock my Athlon 2X 3800, any help appreciated.

I managed to get it into windows at 240 x 10, but after further fiddling about I was forced to reset the cmos. Now it wont boot with those same settings Anyway iv just been testing it at 220 x 10, and its seems stable, but I have afew questions.

What voltage should I keep the ram/cpu be set to?
Should ram settings should I use? (Cas/Tras/Trcd/Trp etc)
Why wont it boot at 240.0 x 10 if it did previously, any ideas?

Any other tips appreciated, I got the cpu today so just decided to have a mess about with it

ps. Full spec in sig
