Hi,

I try to install 16x8GB ram on this motherboard in combination with 2 CPU (Intel E5 V1 serie)
The memory modules all have the same spec: 8GB 2RX4 PC3L 10600R Samsung M393B1K70CHD

They are seated like this:
P1-DIMMA1/P1-DIMMB1, P2-DIMME1/P2-DIMMF1, P1-DIMMC1/P1-DIMMD1, P2-DIMMG1/
P2-DIMMH1, P1-DIMMA2/P1-DIMMB2, P2-DIMME2/P2-DIMMF2,
P1-DIMMC2/P1-DIMMD2, P2-DIMMG2/P2-DIMMH2

The server stalls with POST code B7 or BA

If I install only 12 modules, it works fine.

Any thoughts?

Re-seat your CPUs. Make sure to check for any bent socket pins. When reinstalling, make sure to apply even pressure.
