Is M393A4K40DB2-CWE Compatible With My System?
Before ordering, verify that your server or motherboard supports 288-pin DDR4-3200 ECC registered RDIMM memory and a dual-rank 2Rx4 organization. This module is not interchangeable with non-ECC UDIMM, ECC UDIMM, SODIMM, LRDIMM, DDR3 or DDR5 memory.
The 2Rx4 designation means the module contains two logical ranks and uses x4-width DRAM components. It does not indicate the number of physical modules included. Each quantity ordered includes one physical 32GB RDIMM.
When adding this module to an existing system, confirm the supported capacity, speed, rank organization and memory-population rules. Avoid mixing RDIMMs with LRDIMMs or unbuffered DIMMs. Although some servers permit different RDIMM ranks within an approved configuration, support depends on the processor and motherboard. The module may also operate below 3200 MT/s when limited by the platform or existing memory.
