32GB DDR5 ECC RDIMM for Supermicro Servers

This registered DDR5 module delivers 32GB of error-correcting memory at 4800MHz with a CL40 latency. It is built for Supermicro GPU SuperServer platforms such as the SYS-821GE-TNHR and SYS-421GE-TNRT where data integrity is mandatory.

DDR5 4800 registered limits and platform constraints

The DDR5 4800 standard caps transfer rates at 4800MT/s and the registered buffer adds one cycle of latency versus unbuffered DIMMs. ECC operation requires a motherboard chipset and BIOS that expose the ECC syndrome registers; consumer desktop boards will not enable the feature.

Tool-free installation and common pitfalls

The 288-pin RDIMM seats in a standard DDR5 server slot with the ejector tabs locking automatically. Most failures come from mixing registered and unbuffered modules, populating slots in the wrong sequence for the specific Supermicro model, or leaving the BIOS at default speeds instead of selecting the rated 4800MHz profile.

Questions about this item

Should I choose the 32GB single module or look for a multi-stick kit?

This listing is a single 32GB 1Rx4 RDIMM. If your Supermicro server has free 288-pin slots you can add one module now and match another identical stick later for dual-channel performance.

What does the 4800 MT/s rating deliver inside a Supermicro GPU SuperServer?

The module runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.10V, giving the rated bandwidth when the platform memory controller is set to 4800 MT/s in the BIOS.

How does the 288-pin ECC RDIMM interface limit speed and capacity on these systems?

The registered 288-pin DDR5 interface supports the 4800 MT/s JEDEC standard; the server chipset and CPU memory controller determine the maximum populated speed and total capacity per channel.
