A-Tech 8GB DDR4 2666 ECC RDIMM 1Rx4 288-Pin Server RAM

SKU CH-DH01-DVPWY

An 8 GB DDR4 2666 MHz registered ECC module with CL19 latency for servers and workstations

  • Capacity8GB
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered

Capacity 8GB

  • ECC protection guards data integrity in servers
  • 8 GB DDR4 2666 MHz registered module
  • Single-rank 1Rx4 layout simplifies channel population
  • 20 V standard voltage reduces power draw
  • 288-pin DIMM fits DDR4 server slots only

Server Memory Upgrade

This 8 GB DDR4 2666 registered DIMM adds ECC-protected capacity to compatible servers and workstations. The 288-pin module operates at 1.20 V with CL19 latency and a single-rank 1Rx4 layout. It is built for systems that require registered memory and will not function in standard desktop or laptop platforms.

Replacing Slower DDR4 Modules

Swapping out lower-speed DDR4 RDIMMs or filling empty slots raises throughput to PC4-21300 levels. The jump is worthwhile when workloads are memory-bound and the platform supports 2666 MT/s registered operation. Systems limited to slower DDR4 speeds or unbuffered memory cannot use this module.

Eight Gigabytes of Registered Capacity

The 8 GB module handles virtualization hosts, database buffers and multi-user workloads that benefit from ECC integrity. Headroom ends when aggregate demand exceeds the installed DIMM count or when the platform caps memory below the required total. Additional modules are needed for larger datasets.

Questions about this item

Will this 288-pin DDR4 RDIMM fit in my server's memory slots?

This module uses the standard 288-pin DDR4 DIMM form factor and requires a server or workstation motherboard with registered ECC DDR4 slots. It is not compatible with desktop or laptop systems.

What BIOS setting or seating step is most often missed when installing this registered ECC module?

The module must be seated firmly until the retention clips click on both ends, and the system BIOS must support registered ECC memory; otherwise the server will not POST or will report a memory error.

Does this 1.20V CL19 module need any firmware updates or periodic replacement?

No firmware updates are required for the memory itself. The module is tested for lifetime reliability; replacement is only needed if a hardware fault occurs or if you expand capacity beyond the current 8 GB.
