Hi Dangsta,
hope the RMA doesn't take too long.. As for overclocking the RAM, as long as you don't apply too much extra voltage you'll be ok. Most dimms run from 1.8 to 2.00 vdimm and you can push RAM further with extra voltage but this is when heat starts to become a problem so your better off buying higher spec RAM and keeping the voltage in the normal range.
