32GB DDR5 4800 ECC RDIMM for Supermicro workstations

This registered DDR5 module delivers 32GB of error-correcting memory at 4800 MT/s with CL40 latency. It is built for the Supermicro SuperWorkstation SYS-551A-T and the X13SWA-TF motherboard, using 1Rx4 organisation and 1.10V operation. The 288-pin RDIMM form factor fits server and workstation platforms that require registered ECC memory.

Single-module kit simplifies capacity scaling

The package contains one 32GB stick, letting administrators add capacity in precise increments without populating channels in pairs. No heat spreader is included, which keeps the module height low for dense chassis and allows unrestricted airflow across the PCB. Samsung, Micron or Hynix DRAM chips are used depending on supply, all validated for the target platform.

DDR5 4800 registered ECC requires compatible

The module operates at the JEDEC base data rate of 4800 MT/s and will not negotiate higher speeds on this hardware. Registered signalling and on-die ECC add latency compared with unbuffered desktop memory, so workloads that favour low latency over data integrity may not benefit. Systems lacking DDR5 RDIMM support or ECC capability cannot use this module.

Questions about this item

Will the 288-pin DDR5 RDIMM need any firmware updates or reconfiguration after extended use in a Supermicro SYS-551A-T?

No firmware updates are required for the memory module itself; the registered DDR5 RDIMM operates at the rated 4800 MT/s CL40 once the platform is configured for the installed capacity.

What is the first limit reached when the 32 GB 1Rx4 module runs sustained workloads at 4800 MT/s?

The module is rated for 1.10 V continuous operation at DDR5-4800 CL40; sustained loads stay within that voltage and timing envelope without throttling.

How much heat and power does the 1.1 V 32 GB ECC RDIMM produce during all-day server operation?

At 1.10 V the module draws low power typical for DDR5-4800 registered DIMMs and has no heat spreader, relying on chassis airflow for cooling.
