Jase, this is a quote from your mobo manual:
Memory 4 x 1.8V DDR2 DIMM sockets supporting up to 16 GB of system memory (Note 1)
Note 1 : Only for GA-EP43-DS3L - which is your board.
Your memory spec from the OCZ website is: 1.9 to 2.1 Volts.
Basically in standard setup your memory is only getting 1.8 Volts - that's why it keeps failing and stopping.
I would up your memory voltage to 1.9v, the minimum for that memory.
Have a look here as others have had similar problems.
