4GB DDR4 2400MHz DIMM for desktop upgrades

This single 4GB module runs at DDR4 2400 (PC4-19200) with a tested frequency of 2400 and standard 1.20V operation. It is an unbuffered non-ECC DIMM built for AMD and Intel desktop platforms. Buyers who need more than 4GB of capacity will require additional modules or a higher-density kit.

288-pin unbuffered build fits standard desktop slots

The stick uses the 288-pin DDR4 DIMM form factor and is specified as a direct replacement for Samsung M378A5244BB0-CRC and M378A5244CB0-CRC. Its 1Rx16 organisation and 1.2V voltage match the DDR4 baseline, so it drops into any compatible desktop motherboard slot without registration or buffering. Systems that demand registered or ECC memory cannot use this module.

DDR4 2400 speed ceiling limits peak bandwidth

The PC4-19200 rating sets the maximum data rate at 2400 MT/s, so the module cannot exceed that throughput even if the memory controller supports faster grades. Mixing it with faster DDR4 will force the faster sticks to run at 2400. Platforms limited to earlier DDR generations or to lower maximum frequencies will not accept this memory at all.
