Desktop DDR4 upgrade for Samsung replacement

This 4GB DDR4 module runs at 2933MHz with CL21 timing and 1.20V operation. It is built as an unbuffered, non-ECC DIMM using Samsung chipset components. The stick serves as a direct replacement for the Samsung M378A5244CB0-CVF part number.

Fits standard DDR4 desktop slots without extra

The 288-pin DIMM installs in any desktop motherboard that accepts DDR4 memory at the rated speed. No heat spreader is included, so the module keeps a low profile inside compact cases. It frees up headroom for CPU coolers or additional sticks.

Replaces original Samsung DDR4 2933MHz CL21 modules

The upgrade is worthwhile when a system has a failed stick or needs extra capacity for multitasking. Matching the same frequency, voltage and latency preserves stability without BIOS changes. Verify the motherboard supports DDR4 2933 before purchase.

Fragen zu diesem Artikel

Will this 4 GB DDR4 2933 MHz module fit my desktop's 288-pin DIMM slots?

Yes, the stick is a standard 288-pin unbuffered DIMM that plugs directly into any desktop DDR4 slot supporting 2933 MHz operation.

Does the CL21 latency and 1.20 V voltage match the Samsung M378A5244CB0-CVF spec so I can mix it with an existing stick?

The module is rated CL21 at 1.20 V, matching the listed Samsung part, so it will run at the same timings and voltage when installed alongside an identical stick.

My motherboard only supports non-ECC memory — is this module compatible?

The module is a non-ECC unbuffered DIMM, making it suitable for consumer desktop boards that require non-ECC memory.
