A-Tech 8GB DDR4 2666MHz ECC RDIMM 1Rx8 CL19 1.2V Server Memory

SKU CH-SFVK-Q9FSY

An 8 GB DDR4 2666 MHz ECC registered DIMM with CL19 latency and 1.2 V operation for server and workstation upgrades

  • Capacity8GB
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered
  • ECC protection guards data integrity with registered DDR4 2666MHz operation
  • 8GB capacity expands server memory for heavier workloads
  • CL19 latency at 1.2V delivers efficient performance per module
  • 288-pin RDIMM form factor fits standard DDR4 server slots
  • Micron chipset ensures tested compatibility for MTA9ASF1G72PZ-2G6J1 replacement

Server Memory Upgrade

This A-Tech 8GB DDR4 2666MHz ECC RDIMM module is a compatible replacement for the Micron MTA9ASF1G72PZ-2G6J1. It targets administrators upgrading or repairing registered DIMM slots in servers and workstations that require error-correcting memory. The 1Rx8 organisation and 1.20V operation match the original specification.

Compatibility Focus

The module suits systems designed for DDR4 2666 registered ECC DIMMs with a CL19 latency profile. Builders needing unbuffered UDIMMs, non-ECC memory, or speeds other than 2666 MHz should look at different parts. The 288-pin form factor fits only motherboards wired for DDR4 registered DIMMs.

Deciding Specification

Registered ECC with a 1Rx8 rank configuration is the single attribute that determines whether this DIMM will function in a given platform. The memory controller must support registered operation and ECC; otherwise the module will not initialise. Verify the platform documentation for registered ECC support before purchase.

Highlights

  • ECC protection guards data integrity with registered DDR4 2666MHz operation

Questions about this item

Should I choose the 8GB DDR4 2666MHz ECC RDIMM or a different capacity for my server?

This module is an 8GB DDR4 2666MHz ECC RDIMM with CL19 latency and 1.20V operation. Select it when your platform requires registered ECC memory in a single 8GB stick.

What does the DDR4 2666 (PC4-21300) rating mean for actual workload performance?

The DDR4 2666 rating indicates a 2666 MT/s data rate with CL19 timing. In a compatible server it delivers the bandwidth and error correction needed for virtualization and database tasks.

Is the 288-pin DDR4 RDIMM interface compatible with my system's memory slots?

The module uses a 288-pin DDR4 DIMM form factor with registered (RDIMM) signalling and ECC. It fits servers and workstations that specify DDR4 RDIMM support.
