Motherboard Supermicro x8dtn + ( https://www.supermicro.com/products/motherboard/QPI/5500/X8DTN_.cfm?IPMI=O ). Memory KVR1333D3LD4R9S / 8G installed in the slots:

P1 DIMM3A P1 DIMM2A P1 DIMM1A P2 DIMM1A P2 DIMM2A P2 DIMM3A

Attempting to install the KVR1333D3E9S / 8G module in slot P1 DIMM1B causes the server not to start. If you leave only KVR1333D3E9S / 8G - then the server is turned on.

How to ensure that both types of memory work?

    KVR1333D3LD4R9S / 8G is registered, and KVR1333D3E9S / 8G is not registered, it is simply ECC, they will not work together.

    • Recommend memory compatible with KVR1333D3LD4R9S / 8G for additional installation in the server. - Dan
    • Well, any with similar characteristics, that is: 1333Mhz and CL9, be sure to be two-ranked, that is, 2Rx2 and L can be, that is, not 1.5V but 1.35v, it is usually called PC3L - pnp2000
    • ps: it is difficult to say a specific model where and how it will be bought. I take myself on eBay, it turns out 7-8 tr. for 64GB - pnp2000
