a problem might not show up for a long time.

Ive run memtest overnight and had a single fail 6 hours in.

Also even if memtest does not show up a fault it does not mean its not faulty

Also if memtest does show up a fault then there are steps you can take. Firstly drop the memory speed ( as a rule nowadays there will be a step inline with the fsb without having to lose CPU clocks) then slacken the timings. You might find your ram will run fine a couple of hundred mhz lower

also make sure the vdimm valtage is what the ram is specced for if its performance ram it may need higher voltage
