System-specific DDR5 ECC kit

This 256 GB kit contains eight 32 GB DDR5 4800 CL40 registered DIMMs built for Supermicro SuperWorkstation SYS-751A-I and X13DAI-T platforms. It targets administrators who need maximum registered ECC capacity on those qualified systems.

DDR5 4800 registered ECC limits

The modules run at 1.10 V with a CL40 latency and a single-rank 1Rx4 organisation on the DDR5 4800 (PC5-38400) interface. Registered signalling and on-die ECC add command-cycle overhead that caps raw throughput compared with unbuffered memory.

Straightforward DIMM installation

The 288-pin RDIMMs seat in standard DDR5 slots without extra cables or firmware steps. Populating all eight channels requires the board to train each rank at 4800 MT/s; a single mismatched module or incorrect slot order will halt POST.

Questions about this item

Should I choose the 256GB kit or look for a different capacity for my Supermicro SYS-751A-I?

This kit provides 256GB across eight 32GB modules, filling all eight slots on the Supermicro SYS-751A-I for maximum supported capacity.

What does the 4800 CL40 rating deliver in a real Supermicro SuperWorkstation?

The modules run at DDR5 4800 with CAS latency 40, giving 38400 MB/s peak bandwidth per module and registered ECC operation for error correction under load.

Does the 288-pin DDR5 RDIMM interface limit speed or capacity on the X13DAI-T motherboard?

The 288-pin RDIMM form factor is the native DDR5 server standard; the board's memory controller caps at 4800 MT/s, so this kit runs at the maximum supported data rate.
