Server Memory Upgrade

This 16GB DDR4 module adds ECC-protected capacity to compatible servers and workstations. It runs at 2133MHz with a CAS latency of 15 and operates at 1.2V through a 288-pin UDIMM interface. The unbuffered 2Rx8 design suits systems that require error-correcting memory without registered signalling.

Replaces Non-ECC or Smaller Modules

The jump is worthwhile when data integrity matters more than raw bandwidth, such as in database or virtualization hosts. It upgrades from non-ECC UDIMMs by adding single-bit error correction and from lower-capacity ECC sticks by doubling density per slot. Systems limited to 2133MHz gain capacity without forcing a downclock.

Sustained Load Behaviour

Under continuous workloads the ECC logic corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 1.2V operation keeps power draw steady across extended periods, while the unbuffered topology avoids the extra latency step of registered modules. Stability is maintained through standard JEDEC timings rather than aggressive overclock profiles.

Questions about this item

Will this 288-Pin DDR4 UDIMM fit my server motherboard?

The module uses the standard 288-pin DDR4 UDIMM form factor, so it fits any server or workstation board that accepts unbuffered DDR4 ECC memory.

What BIOS setting is often missed when installing this ECC UDIMM?

After seating the 16GB stick, enable ECC support in the BIOS; many builders forget this step and the module then runs without error correction.

When should I expect to replace this 16GB 2Rx8 module?

DDR4 ECC UDIMMs have no moving parts and typically last the life of the server; replace only if memory diagnostics report uncorrectable errors.
