32GB DDR4 3200 ECC Registered module

This 32GB DDR4 3200 ECC Registered RDIMM delivers 25600 MT/s bandwidth with CL22 latency at 1.20V. It is built for servers that require error correction and registered signalling for data integrity. The 2Rx8 dual-rank organisation suits multi-slot configurations in compatible Supermicro UP and DP platforms. Buyers needing non-ECC or unbuffered DIMMs for consumer boards cannot use this module.

Compatible Supermicro UP and DP server upgrade

The module matches the memory specification for listed UP Server models SSG-520P-ACTR12H, SSG-520P-ACTR12L, SSG-540P-E1CTR36H and SSG-540P-E1CTR36L. It also fits DP Server models SSG-620P-ACR12H, SSG-620P-ACR12L, SSG-640P-E1CR24H, SSG-640P-E1CR24L, SSG-640P-E1CR36H and SSG-640P-E1CR36L. Adding this 32GB stick expands total capacity without changing voltage or speed settings. Systems already at the maximum supported DIMM count per channel cannot accept additional modules.

Sustained operation at 1.20V with ECC active

Registered buffering reduces electrical load on the memory controller during continuous read-write cycles. ECC detects and corrects single-bit errors that accumulate under long-running workloads. The 1.20V operating voltage keeps power draw stable across extended periods. Modules without registered buffering or ECC lack these protections for 24/7 server duty.

Soalan tentang produk ini

Does this 288-pin DDR4 RDIMM fit the memory slots on a Supermicro SSG-620P-ACR12H server?

Yes, the module is listed as compatible with the SSG-620P-ACR12H and other DP Server models in the 620 and 640 series.

What is the correct way to install this registered ECC module so the server recognises the full 32 GB capacity?

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify the total memory in BIOS.

When should I plan to replace this CL22 1.20 V DDR4 module in a production server?

Registered ECC DDR4 modules typically run for years; replace only if memory diagnostics report correctable errors increasing over time or the server fails to POST with the module installed.
