Server ECC Registered Memory Upgrade

This OWC 16GB DDR4 2933MHz module is built for Dell PowerEdge servers including the FC640, M640, MX740c, MX840c and R450. It operates at 1.2V with a CL21 latency and uses a 288-pin RDIMM form factor. The module is new and validated as a direct replacement for specific Dell part numbers.

Registered ECC Architecture Required

The single specification that determines fit is the registered ECC design; this memory will not work in standard desktop computers and cannot be mixed with unbuffered modules. Backward compatibility covers 2133MHz, 2400MHz and 2666MHz bus speeds. Buyers must confirm their system requires registered ECC RDIMMs before purchase.

Suited For Verified Dell PowerEdge Platforms

This module suits administrators upgrading or repairing the listed Dell PowerEdge models where registered ECC memory is mandatory. It is not for desktop PCs, workstations needing unbuffered DIMMs, or any server outside the validated compatibility list. Systems requiring different capacities, ranks or voltage should look at other modules.

Perguntas sobre este artigo

What does the 2933MHz speed mean once the module is installed in a Dell PowerEdge R450?

The module will run at 2933MHz CL21 if the platform supports that data rate; otherwise it will down-clock to 2666MHz, 2400MHz or 2133MHz automatically.

How does the DDR4 PC4-23400 interface limit performance in practice?

PC4-23400 is the JEDEC peak bandwidth rating for 2933MHz DDR4; actual throughput is capped by the server memory controller and the CL21 latency of this module.

What physical slot and form factor does this 288-pin RDIMM need to fit a Dell PowerEdge M640?

It requires a standard 288-pin DDR4 DIMM socket; the registered design and 2Rx8 organisation mean it must go into a server or workstation board that supports ECC registered memory.
