8GB DDR4 2933 ECC UDIMM for Servers

This 8GB DDR4 module runs at 2933MHz with CL21 latency and 1.20V operation. It uses ECC unbuffered architecture in a 1Rx8 configuration with major brand chips. The 288-pin DIMM is built as a direct replacement for the Samsung M391A1K43DB2-CVF part.

Unbuffered ECC limits and platform constraints

ECC UDIMM memory works only in platforms that support unbuffered error-correcting modules. Registered or load-reduced DIMMs cannot be mixed with this type. The 2933MHz speed will downclock to the highest rate the memory controller officially supports.

Upgrade from smaller or non-ECC DDR4 modules

Replacing 4GB sticks or non-ECC DDR4 with this 8GB ECC UDIMM adds capacity and data integrity for server workloads. The jump is worth it when the system board accepts unbuffered ECC and the application benefits from error correction.

Questions about this item

Should I pick the 8 GB module or look for a different capacity?

This listing is a single 8 GB stick; add more identical modules to reach your board's maximum supported memory.

What does the 2933 MT/s rating deliver in a live server?

The module runs at DDR4 2933 (PC4-23400) with CL21 latency, giving the peak bandwidth your platform allows at that speed.

Is the 288-pin DDR4 UDIMM keyed for ECC unbuffered slots?

Yes — it is a 288-pin DDR4 ECC UDIMM (unbuffered) designed for server and workstation boards that support ECC unbuffered memory.
