A-Tech 32GB DDR4 2666MHz ECC RDIMM 2Rx4 CL19 1.20V 288-Pin 01AG619 server RAM

SKU CH-XPX3-RJFMR

32 GB DDR4 2666 MHz ECC registered DIMM with CL19 latency and 1.20 V operation

  • Capacity32GB
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered
  • 32 GB capacity handles heavy server workloads
  • DDR4 2666 MHz speed accelerates data throughput
  • ECC RDIMM design detects and corrects memory errors
  • Registered 2Rx4 architecture improves signal integrity
  • 20 V operation matches standard DDR4 voltage

Capacity and purpose

This is a 32 GB DDR4 registered DIMM with ECC, built for servers and workstations that require error correction and signal buffering. It replaces the IBM-Lenovo 01AG619 module in compatible systems. The single-module design suits upgrades where only one slot is available or where maximum per-slot density is needed.

Thermals and power

The module operates at the standard DDR4 voltage of 1.20 V and carries a CL19 latency rating at 2666 MHz. As a registered ECC part it draws slightly more power than unbuffered equivalents, but stays within normal DDR4 thermal limits for passively cooled server chassis. No active cooling is required on the module itself.

Compatibility assurance

A-Tech validates each unit against the 01AG619 specification and provides US-based technical support to confirm fit before installation. The lifetime warranty covers the module for as long as the original purchaser owns it. Buyers who need non-ECC memory, unbuffered DIMMs or a different pin count should look elsewhere.

Perguntas sobre este artigo

How do I install this 288-Pin DDR4 RDIMM and what step is often missed?

Power down the server, open the chassis, align the module notch with the slot key, press firmly until both retention clips click, then verify the system recognises the full 32 GB at 2666 MHz in BIOS; the step often missed is seating the module evenly so both clips engage.

What maintenance or replacement will this ECC RDIMM need later?

No routine maintenance is required; if a correctable error count rises or the module fails memtest, replace the single 32 GB stick — ECC logging in the OS or IPMI will flag the issue.

What limit appears first under sustained heavy workloads?

The CL19 latency at 2666 MHz and 1.20 V sets the throughput ceiling; sustained loads will hit bandwidth and latency limits before thermal throttling on this registered DIMM.
