A-Tech 64GB DDR4 2133 ECC RDIMM 15-102952-01

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.
