Is M393A2K40DB2-CWE Compatible With My System?
Before ordering, verify that your server or motherboard supports 288-pin DDR4-3200 ECC registered RDIMM memory and a single-rank 1Rx4 organization. This module is not interchangeable with non-ECC UDIMM, ECC UDIMM, SODIMM, LRDIMM, DDR3 or DDR5 memory.
The 1Rx4 designation means the module contains one logical rank and uses x4-width DRAM components. It does not mean that the product includes four modules. Each quantity ordered includes one physical 16GB 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 allow different RDIMM ranks in separate channels or slots, support depends on the specific platform. The module may also operate below 3200 MT/s when limited by the processor, motherboard or existing memory configuration.
