Is M393A4K40DB2-CVF Compatible With My System?
Before ordering, verify that your server or workstation supports 288-pin DDR4-2933 Registered ECC RDIMM memory. A system that supports standard desktop DDR4 memory will not necessarily support registered server memory.
This module is not interchangeable with non-ECC UDIMM, ECC UDIMM, Load-Reduced LRDIMM or laptop SODIMM memory. Although RDIMM and LRDIMM modules are both designed for servers, they use different buffering architectures. Therefore, most systems do not permit them to operate together.
For best results, match the complete part number, capacity, speed, voltage, module type and 2Rx4 organization with the system documentation or existing memory. However, the module may operate below 2933 MT/s when limited by the processor, motherboard or installed memory configuration.
