Black Diamond Memory BD8G2133MQO22 8GB DDR4 2133 ECC Unbuffered SO-DIMM server RAM

8 GB DDR4 ECC SO-DIMM for servers

This module provides 8 GB of DDR4 2133 ECC unbuffered memory in a 260-pin SO-DIMM form factor. It is built for servers and workstations that require error-correcting code protection. The dual-rank 2Rx8 organisation supports standard PC4 17000 bandwidth. Systems needing non-ECC or registered DIMMs cannot use this module.

Straightforward SO-DIMM installation

Align the notch with the slot key and press firmly until the side latches click into place. The 260-pin layout matches the DDR4 SO-DIMM standard, so no adapters are required. A common issue occurs when the module is seated at an angle, preventing the latches from engaging and causing the system to fail POST. Verify that the platform accepts unbuffered ECC SO-DIMMs before purchase.

DDR4 2133 speed ceiling

The PC4 17000 rating sets a maximum data rate of 2133 MT/s, which limits throughput on workloads that benefit from higher memory clocks. If the platform supports faster DDR4 speeds, this module will downclock to 2133 MT/s. Latency and bandwidth are fixed by the JEDEC specification for this speed grade. Applications demanding greater memory bandwidth will not reach their potential with this part.
