16 GB DDR4 ECC UDIMM for servers

This 16 GB DDR4 2933 MHz module is built for server and workstation platforms that require error-correcting unbuffered memory. It operates at the standard 1.2 V and carries a CL21 latency rating. The stick uses a 2Rx8 organisation with major-brand chips.

ECC unbuffered with 2Rx8 layout

The defining specification is the ECC UDIMM format combined with a dual-rank 2Rx8 configuration. Systems that expect registered DIMMs or single-rank modules will not accept this part. Verify that your motherboard supports unbuffered ECC memory before ordering.

Suits admins upgrading compatible

Buyers who need registered RDIMMs, higher frequencies, lower latencies, or non-ECC memory should look elsewhere. This module targets exact replacements for the Samsung M391A2K43DB1-CVF reference in qualified server boards.

Questions sur cet article

What does 2933 MHz mean once the module is installed in a server?

The memory runs at 2933 MT/s, delivering PC4-23400 bandwidth for server workloads; actual throughput depends on the CPU memory controller and channel population.

How does the ECC UDIMM interface affect error handling?

ECC UDIMM provides single-bit error correction and multi-bit detection on an unbuffered 288-pin DDR4 module without register delay.

What physical slot and clearance does this 288-pin DIMM require?

It fits a standard DDR4 288-pin UDIMM slot; the 2Rx8 layout uses a typical low-profile height that clears most server heatsinks.
