Re. RAM and the QVL. Though not tested, it is pretty generic as far as specs go so should have been no problems but, as noted in your second post, the timing is not correct. Before ordering new RAM, could you try your's in your brother's rig, check speed, voltage and timing in the BOIS to make a comparison. Do the same with his RAM in your rig.
The RAM timing clock cycle, how long time is set for each instruction, the higher the numbers, the "looser" longer the cycle takes. The lower the number, "tighter" the shorter the time taken. A more tech explanation, > http://forum-en.msi....mings-explained
Try adjusting the RAM setting, > page 35/36 User Manual, Advance CPU Core Features.
If available, the last item on that screen should be XMP, Default is Disabled. Select Profile with the correct timing, > save settings and exit. > Allow the desktop to be displayed, then, > Reboot, > enter BIOS, check the RAM setting.
Do some testing,Then >

Some RAM, tested on your board by the RAM manufacturer. Please check it is the MB you have installed.
