32 GB DDR5 ECC RDIMM kit for Supermicro SYS-551A-T

This registered DDR5 kit contains two 16 GB modules rated at 4800 MT/s with CL40 latency. It is built for the Supermicro SuperWorkstation SYS-551A-T and the Super X13SWA-TF motherboard where ECC RDIMM memory is required.

Registered ECC with 1Rx8 organisation

The single specification that decides fit is the registered ECC RDIMM format combined with a 1Rx8 rank structure. Only systems expecting registered error-correcting DDR5 at 1.1 V with this exact pin-out and rank configuration will accept the kit.

Matched pair eliminates mixed-rank uncertainty

The two modules are packaged together as a tested 32 GB pair so the memory controller sees identical timing and rank behaviour on both channels. No additional software or accessories are included; the kit relies on the motherboard SPD data for automatic configuration.

Questions about this item

What does the 4800 MHz DDR5 rating mean once the modules are installed in a Supermicro workstation?

The 4800 MHz DDR5 rating sets the maximum JEDEC-standard data rate the kit will run at in a Supermicro SYS-551A-T or X13SWA-TF system, delivering PC5-38400 bandwidth at 1.10 V with CL40 latency.

How does the 288-pin RDIMM interface and registered ECC design affect what the memory controller can do?

The 288-pin DDR5 RDIMM interface adds a register between the DRAM and the memory controller, allowing the Supermicro platform to support higher capacities and maintain signal integrity with ECC error correction across both 16 GB 1Rx8 modules.

What physical clearance and slot requirements must the chassis meet for this 32 GB kit?

The kit uses standard-height 288-pin DDR5 RDIMM modules without heat spreaders, so it fits any Supermicro SYS-551A-T or X13SWA-TF DIMM slot that accepts registered ECC memory and provides 1.10 V power.
