32GB DDR4 2933MHz ECC SO-DIMM for servers

This 32GB module runs at 2933MHz with CL21 latency and 1.20V operation. It uses a 260-pin SO-DIMM form factor and includes ECC unbuffered technology. The part is designed as a direct replacement for Samsung M474A4G43AB1-CVF in compatible server and workstation platforms.

Unbuffered ECC SO-DIMM with 260-pin layout

The stick follows standard DDR4 SO-DIMM dimensions and installs in any 260-pin slot that accepts unbuffered ECC memory. Gold-edge contacts resist oxidation during repeated seating. Single-rank 2Rx8 organisation keeps electrical loading low for dense memory configurations.

Verify your system accepts DDR4 2933 ECC SO-DIMM

Check the motherboard or laptop manual for supported speeds, maximum capacity per slot, and ECC unbuffered compatibility before ordering. Some platforms restrict ECC to registered modules or limit frequency to lower JEDEC bins. Confirm voltage tolerance matches 1.20V DDR4 specification.
