SuperMicro SYS-551A-T memory kit

This 128GB kit contains four 32GB DDR5 4800 RDIMM modules built for the SuperMicro SuperWorkstation SYS-551A-T and X13SWA-TF platforms. Each stick runs at 1.10V with CL40 latency and on-die ECC. Registered signalling and 1Rx4 organisation keep data integrity high under sustained server workloads.

Suited for registered ECC platforms only

The modules require a motherboard that accepts 288-pin DDR5 RDIMMs with registered buffering and ECC support. Desktop boards that take only unbuffered UDIMMs cannot use this kit. Laptops and small-form-factor systems using SO-DIMM slots are also incompatible. Buyers needing non-ECC or unbuffered memory should look elsewhere.

Registered ECC with 1Rx4 organisation

Registered buffering places a register between the DRAM and the memory controller, reducing electrical load so larger capacities remain stable. The 1Rx4 chip arrangement delivers 32GB per rank while maintaining error correction. This combination decides whether the kit will post and run reliably in the target SuperMicro workstation.

Preguntas sobre este artículo

Should I pick the 4×32 GB kit or a different capacity for my Supermicro SYS-551A-T?

The kit provides 128 GB total using four 32 GB modules, matching the four-channel layout of the Supermicro SYS-551A-T workstation for full bandwidth.

What does the DDR5 4800 CL40 rating actually deliver in this workstation?

The modules run at 4800 MT/s with CAS latency 40 at 1.1 V, giving the peak transfer rate the platform supports for registered ECC memory.

Does the 288-pin RDIMM interface limit the speed on my Supermicro board?

The 288-pin RDIMM form factor is the standard for DDR5 registered ECC; the board's memory controller caps operation at the rated 4800 MT/s.
