  • 288-pin RDIMM form factor fits standard server memory slots

8 GB DDR4-2666 ECC RDIMM

This Samsung module delivers 8 GB of DDR4 memory at 2666 MHz with ECC error correction for server workloads. The 1Rx8 layout and CAS 19 timing suit registered DIMM slots in compatible platforms.

Compatibility check

Verify that your motherboard supports DDR4 registered ECC RDIMMs and accepts 288-pin modules at this speed. Confirm the maximum capacity per slot and total system limit before ordering.

Who this suits

Ideal for administrators upgrading or repairing servers that require registered ECC memory. Not suited for desktop boards that only accept unbuffered non-ECC DIMMs or for builds needing higher capacity per module.
