Samsung DDR4 2133 UDIMM

This 4 GB DDR4 2133 module is built for Samsung desktop PCs that accept non-ECC unbuffered UDIMMs. It uses major-brand Samsung, Micron or Hynix chips in a 1Rx8 layout and runs at the standard 1.20 V. The part number MD17000-418K1 cross-references Samsung M378A5143DB0-CPB for direct replacement.

Check DDR4 2133 UDIMM support

Verify that your Samsung desktop motherboard has a free 288-pin DDR4 slot and is rated for PC4-17000 speed with CL15 timing. Confirm the board does not require ECC or registered memory, because this stick is neither. Consult the system manual for maximum capacity per slot and total system limit before ordering.

Single stick no heat spreader

The package contains only the bare 4 GB UDIMM without a heat spreader or any bundled software. No cables, adapters or documentation are included beyond the module itself. Installation is a simple press-in procedure that takes minutes, but thermal headroom in tight chassis may be lower than with spreader-equipped kits.

Questions about this item

Does the module ship with any accessories or do I need to buy a heat spreader separately?

The package contains only the single 4 GB DDR4 UDIMM; no heat spreader or extra parts are included and none are required for installation.

Should I pick this 4 GB CL15 stick or look for a different capacity in the same series?

This part is a single 4 GB module rated at DDR4 2133 CL15; choose it when your board has a free 288-pin slot and you need exactly 4 GB, otherwise select the higher-capacity variant that matches your target total memory.

What does the 2133 MT/s rating actually deliver once the stick is seated in my desktop?

The module runs at 2133 MT/s with CL15 latency at 1.20 V, giving standard DDR4 bandwidth for everyday desktop workloads when the motherboard supports that speed.
