Да я не пугаю, просто предположение не более.

MSI Reminds You...
- Dual-channel DDR works ONLY in the 3 combinations listed in
the table as below.
- Please select the identical memory modules to install on the dual
channel, and DO NOT install three memory modules on three
DIMMs, or it may cause some failure.
- Always insert the memory modules into the GREEN slots first, and
it is strongly recommended not to insert the memory modules into
the PURPLE slots while the GREEN slots are left empty.
