Thanks for the memory tips guys ....... time to list unwanted bits on ebay OCZ memory, Striker II Extreme, WD Raptor X and EVGA 9800X2 SSC to fund new memory

Really looking to try Micron D9___ IC's rather than the Samsung this time. My ideal scenario is to run at 500FSB with multiplier of 8 and 1:2 memory running at 1000 (2000DDR) then I will stop tweaking and start playing !!.

Let's remember also that this board is still on an early bios.

EF - cheers for the B/P link will pick one up as a spare next time I buy from Scan. Cooling mods are looking great
