Samsung DDR4 2933 UDIMM for desktop upgrades

This 8 GB DDR4 module runs at 2933 MHz with CL21 latency and 1.2 V operation. It uses a 1Rx8 unbuffered non-ECC layout on a 288-pin UDIMM form factor. The stick is built with Samsung chips and targets Samsung desktop systems that accept PC4-23400 memory.

Tool-free slot insertion takes minutes

Align the notch with the motherboard key and press until the retention clips click. No heat spreader means low clearance but also no thermal headroom for sustained heavy loads. The most common issue is mixing ranks or speeds across channels which can force the system to downclock.

DDR4 platform ceiling limits further scaling

The DDR4 interface tops out at the rated 2933 MT/s on this module so faster kits will not run at their advertised speed without motherboard and CPU support. Capacity is fixed at 8 GB per stick and the single-rank design cannot be expanded on the same DIMM. Non-ECC operation rules out error correction for critical workloads.

Questions about this item

How can I verify the module is running at DDR4 2933 CL21 after installation?

Check the memory speed and CAS latency in your system BIOS or a hardware monitoring tool; it should report 2933 MT/s and CL21 at 1.20 V.

What is included in the package and do I need any extra parts?

The box contains one 8 GB 288-pin DDR4 UDIMM (1Rx8, non-ECC, unbuffered); no additional components are required for a compatible desktop motherboard.

Which version should I choose if my system requires the Samsung M378A1K43DB2-CVF part?

This module (part number MD23400-818K1) is built to match that Samsung specification — 8 GB, DDR4 2933, CL21, 1.20 V, 1Rx8 — so select this single 8 GB kit.
