32GB DDR4 2933 Replacement Module

This 32GB DDR4 module runs at 2933 MHz with CL21 latency and 1.20V operation. It is built as an unbuffered 288-pin DIMM using Samsung chipset components. The stick is a direct replacement for Samsung M378A4G43AB2-CVF.

Ideal for Desktop Capacity Upgrades

The single 32GB stick suits owners of compatible desktop boards that accept non-ECC UDIMM memory at this speed. Systems requiring ECC, registered modules or a different pin count should look elsewhere.

No Extras Included

The package contains only the memory module itself. No heat spreader, software, cables or additional hardware are bundled, so the upgrade adds capacity without changing the physical or software environment.
