While the original set was in RMA I had the Kingston HyperX 2400 4x16GB and worked fine. Once I got the replacement I put those in and made sure XMP profile was set and speed was right. Games crash 10 minutes into it with the GSkill replacement RAM. Replaced with the HyperX and no issues for 3 hours. The RMA'd RAM has issues. Do I file for another RMA?

Do you have the latest BIOS for the motherboard? Test each module to see if they both are stable with XMP enabled.

The latest bios was installed and tested each ram individually as well. Xmp profile was used also tested with manually entering the speed and voltage still have issues.

Looks like it's working now. Put one stick in at a time and did a test after adding a stick and that seemed to work out good. So far no issues with crashing or BSOD.
