This is my latest attempt:
DDR500 - 250MHz - 2.5-3-3-8-1T 2.9v @ 3779/3495
I tried 255MHz and on one attempt it got past the bar swiping at the loading screen but rebooted, then I upped the cycle time, and it got into windows, but then gave me a blue screen soooo pretty much my only option right now is to do the voltage mod on the NB because it's at 1.7 and I'm pretty sure that'll help stability of the board if I can get it up to 1.9v (this time without frying my board =/ ) I should be able to get to 266.
Still decent though considering they've only been on a day and haven't really been broken in yet.
Gonna run prime95 right now and see if it's stable at 250, then I can work on re-attempting the voltage mod
