Important compatibility notice – please read before buying
This is NOT standard DDR4 RAM. It is Intel Optane Persistent Memory and requires:

• A server with a 3rd Gen Intel Xeon Scalable (Ice Lake-SP) processor
• A motherboard/BIOS that supports Optane PMem 200 Series (e.g. Dell PowerEdge R650/R750, HPE ProLiant Gen10 Plus, Lenovo ThinkSystem SR650 V2, Supermicro X12)
• Regular DDR4 DIMMs installed alongside it (PMem cannot run alone)

It will NOT work in desktop PCs, workstations, AMD systems, or servers with 1st/2nd Gen Xeon Scalable (those require the 100 Series, NMA…). Please check your platform's documentation before purchasing.
