NEMIX RAM 16GB DDR4 2933MHz ECC RDIMM 2Rx8 CL21 1.2V 288-Pin Dell PowerEdge M640 memory upgrade

Dell PowerEdge M640 memory upgrade

This 16GB DDR4 2933MHz ECC registered DIMM is built for the Dell PowerEdge M640 server. It delivers 16GB of capacity in a single 288-pin module that operates at 1.2V with CL21 latency. The 2Rx8 organisation and on-board error correction suit virtualised workloads and databases that need data integrity.

Replacing slower or smaller DDR4 RDIMMs

Swapping out lower-speed DDR4 modules or smaller-capacity sticks raises both bandwidth and total memory headroom for the M640. The jump is worth it when the server runs near its current memory ceiling or when the existing DIMMs run below 2933MHz, because the higher data rate feeds more instructions per clock to the CPU.

Fitting into an M640 build

The module plugs directly into the server’s 288-pin DDR4 RDIMM slots and draws 1.2V without extra cooling hardware. It frees a slot that a pair of 8GB DIMMs would occupy, leaving room for future expansion while keeping the memory subsystem registered and ECC-protected.
