Like all great problems this one had many things wrong with it.
First the voltages on this motherboard are slightly off. To get the 2.2V I needed for my RAM I had to up the voltage to +0.450 instead of +0.400. This explains the hit and miss I was experiencing.
I disabled my L3 cache in BIOS. I don't know if this is neccesary as I don't know if Q6600's have L3 cache but it's one of the settings I know I disabled.
I disabled Intel Speed Step and I also disabled C1E.
This let me install Vista without any further problems.
In order to install Ubuntu I had to add "irqpoll" to the end of the boot sequence as it was getting an error.
So much thanks to ChrisB17 and to everyone else who took their time to help me! REPS all around!
