Cisco Compatible 64GB DDR4 Module

This A-Tech 64GB DDR4 2133 ECC RDIMM serves as a direct replacement for Cisco part numbers 15-102952-01 and UCS-MR-1X648RU-A. It targets administrators upgrading Cisco UCS servers or compatible workstations that require registered ECC memory. The single module delivers 64GB capacity at 2133MHz with CL15 latency.

Registered ECC Design For Dense Configurations

The 288-pin RDIMM uses a registered buffer and on-die ECC to maintain signal integrity in multi-DIMM server boards. Operating at standard 1.20V DDR4 voltage, it fits into existing DDR4 slots without additional power infrastructure. The 2S4Rx4 (8Rx4) 3DS/TSV rank structure allows higher density per channel than standard dual-rank modules.

64GB Capacity With 2133MHz Headroom

At 64GB this module supports large virtualisation hosts, in-memory databases and heavy container workloads within a single slot. The PC4-17000 rating provides 17GB/s theoretical bandwidth per module. Systems limited to DDR4 2133 or lower will run at rated speed; boards requiring faster DDR4 rates will downclock this module, reducing peak throughput.

Points forts

  • 64 GB capacity handles heavy server workloads
  • DDR4 2133 MHz speed supports PC4-17000 bandwidth
  • ECC RDIMM registered design protects data integrity
  • 2 V DDR4 standard voltage reduces power draw
  • 288-pin DIMM form factor fits compatible server slots

Questions sur cet article

Will the 1.20V voltage stay stable during continuous server workloads?

The module operates at the standard DDR4 voltage of 1.20V and is validated for sustained server operation.

Does the registered ECC design increase heat output compared to unbuffered memory?

Registered ECC RDIMMs add a register chip but run at the same 1.20V; thermal load remains comparable to other DDR4 server modules.

My system has 288-pin DDR4 slots — will this 262-pin module fit?

The specification lists a 288-pin DDR4 DIMM form factor; the 262-pin reference appears to be a documentation inconsistency.
