Hello, trying to figure out why with the first 2 corsair vengeance..2x4GB everything works fine, but when i add the other 2x4GB can not access os and get only blank screen.

Be sure the RAM is properly seated. You should align the stick with the slots and firmly press each into the slot until you hear the plastic retainers "click."

If you have already done that, the second stick may be bad, you should RMA the set for replacement.

do the first set and second set of memory match?
