Target server memory upgrade

This 64GB DDR5-4800 Registered ECC RDIMM is built for the Supermicro H13SSL-NT motherboard. It delivers 2Rx4 rank organisation, 1.1V operation and CL40 timing in a 288-pin form factor. The module matches the exact specifications the platform expects for full-capacity recognition.

Not for non-ECC or consumer boards

Systems that require unbuffered UDIMMs or non-ECC memory cannot use this Registered RDIMM. Laptops and small-form-factor PCs needing SODIMMs are also incompatible. Buyers without a Supermicro H13SSL-NT should verify their motherboard manual before ordering.

64GB DDR5-4800 2Rx4 CL40 spec

The single specification that decides fitment is the 64GB DDR5-4800 2Rx4 CL40 Registered ECC configuration at 1.1V. Only motherboards validating this exact rank, voltage and timing will initialise the module at its rated speed and capacity.

Questions about this item

Will this 288-pin DDR5 RDIMM fit the Supermicro H13SSL-NT memory slots?

Yes. The module is a 288-pin DDR5 RDIMM, which is the exact form factor the Supermicro H13SSL-NT requires. It is not a UDIMM or SODIMM, so it aligns with the board's physical slot keying and registered architecture.

What is the correct installation order for this 2Rx4 ECC RDIMM on the H13SSL-NT?

Consult the Supermicro H13SSL-NT manual for the approved DIMM population sequence. The board has specific slot-filling rules for registered ECC memory; installing in the wrong order can prevent the system from recognising the full 64 GB capacity.

Does this registered ECC module require any firmware updates or ongoing maintenance after installation?

No ongoing maintenance is needed for the memory itself. The ECC function corrects single-bit errors automatically. Keep the motherboard BIOS current per Supermicro's guidance to ensure continued compatibility and stability.
