64GB DDR4 3200 Registered ECC

This 64GB DDR4 3200 RDIMM delivers registered ECC memory for Supermicro UP and DP server platforms. The module operates at 1.20V with CL22 latency and a 2Rx4 organisation. It targets administrators who need maximum capacity per slot in qualified Supermicro SSG-520P, SSG-540P, SSG-620P and SSG-640P systems.

Upgrading from lower-capacity RDIMMs

Replacing smaller registered modules with this 64GB stick increases total memory without consuming additional slots. The jump is worthwhile when workloads exceed the capacity of existing DIMMs and the platform supports 64GB per slot. Systems that require unbuffered memory or speeds above DDR4 3200 cannot use this module.

Sustained-load behaviour

Registered buffering and ECC maintain data integrity during continuous operation in multi-socket servers. The 1.20V rating and CL22 timing provide stable throughput at the rated PC4 25600 bandwidth. Thermal characteristics follow the DDR4 RDIMM specification for the qualified Supermicro platforms listed.

Soalan tentang produk ini

Will this 288-pin DDR4 RDIMM fit my Supermicro SSG-640P-E1CR36H server?

Yes, the module is listed as compatible with the SSG-640P-E1CR36H and other DP servers including SSG-620P-ACR12H and SSG-640P-E1CR24L.

What is the correct way to install this registered ECC module and what step is often missed?

Align the notch on the 288-pin edge connector with the slot key, press firmly until both retaining clips click shut, and ensure the motherboard BIOS is set to run at 1.20 V for DDR4 3200 operation.

When should I plan to replace this 64 GB 2Rx4 kit in a 24/7 server?

ECC registered DDR4 typically runs 5 to 7 years in continuous use; schedule replacement if corrected error counts rise or after a major platform upgrade that changes memory voltage or speed requirements.
