128GB DDR5 4800 ECC RDIMM Server Memory

This single 128GB DDR5 4800 module is built for Supermicro SuperWorkstation SYS-551A-T and Super X13SWA-TF platforms. It operates at PC5-38400 speed with CL40 latency and a 1.10V supply. The 4Rx4 registered design delivers high-capacity error-correcting memory for demanding server workloads.

Registered ECC for Stable Enterprise Operation

The module suits IT professionals running mission-critical databases, virtualization hosts or large-scale analytics on compatible Supermicro hardware. Builders who need non-ECC memory, lower-density sticks, or modules for consumer desktop boards should look elsewhere.

4Rx4 Rank Determines Platform Compatibility

The 4Rx4 organization is the critical specification that decides whether this RDIMM will function in your specific Supermicro system. Verify the motherboard memory-qualified vendor list for 4Rx4 support before purchase.

Questions sur cet article

How do I install this 288-Pin DDR5 RDIMM into the SuperMicro SuperWorkstation SYS-551A-T, and what step is often missed?

Align the notch on the module with the slot key, press firmly until both side clips click shut, then verify in BIOS that the 128GB module registers at 4800MHz with ECC active.

What maintenance or replacement will this 1.10V registered ECC module need over its service life?

No scheduled maintenance is required; the module either operates within spec or it fails, at which point the lifetime replacement warranty covers a direct swap of the 4Rx4 stick.

What limit appears first when this CL40 4800MHz memory runs sustained workloads on the X13SWA-TF motherboard?

The CAS 40 latency at 4800MHz sets the bandwidth ceiling; thermals stay low at 1.10V without a heat spreader, so latency is the first bottleneck under continuous load.
