Test your PSU before sending the RAM back. If the PSU is good and
powerful enough then you probably have bad RAM. I have seen failing or
"cheap" PSU's cause memory problems before.

My problem was just the reverse. One of my new RAM units (three new 500
GB units) failed on boot up or shortly after. Found out which one it
was. Tested the unit it passed. Tested it in each slot. Tested with
other RAM units. Passed the tests (ran for about 30 minutes at full
rated speed.) Replaced the unit that gave blue screen of death and all
was well. Go figure! Note it can't be ths hardware slot since the tests
work.
