Thanks for all the suggestions. I went into the BIOS and changed the "1T/2T 
DRAM Timing" option from "Auto" to "2T". Still unable to compile a kernel...

In the "MB Intelligent Tweaker" I changed "DDR Clock / Timing Mode" and "DDR 
Timing" to Manual. This gave DDR Speed 333mhz - still crashes before I 
managed to compile a kernel...

I've tried various combinations of RAM, and the same happened whenever I 
have more than 2GB. Also - I double checked with the Kubuntoo Live DVD, and 
the same thing happened after a while.

Anything I may have overlooked? I've emailed Gigabyte on the off chance that 
throws up something, as I know this isn't a gentoo problem as I first 
thought.

Cheers
Richard
