Before you start tweaking voltages and replacing PSUs you better test your 
*new* memory modules thoroughly, even if that means that you will be using 
your old machine for a day or so.

Personally I usually remove all memory modules and then test one at a time 
overnight with memtest 86+.  If it gives any errors at all I would send it 
back to the shop.

If they all pass, then voltage and PSU issues will need to be looked at.

Good luck.
