I need to know what ram you have cos you obviously didn't have this much ram when you ran previous operating system. Are they pairs, what make are they and what are the individual specs of the modules.
the ram is fine - he just tried to massively overclock it, with the expected result!
no i didn't it's ddr800 ie 400mhz running twice per cycle to give 800mhz, the bios setting was auto and i changed it to ddr800 not ddr1066
ddr800? Don't you mean ddr2-800? if so, quad pumped off a 200Mhz clock
that's why you do pc's and i draw houses

so is this right then :
Number of processors 1
Number of cores 4 per processor
