DDR5 5600 ECC RDIMM 128GB

This NEMIX RAM module is a 128GB DDR5-5600 registered ECC RDIMM built for the Supermicro H13SSL-N motherboard. It runs at PC5-44800 with CL46 latency and 1.1V. The 2Rx4 dual-rank layout matches the board's memory controller requirements. It installs in a 288-pin slot and uses major OEM chips.

Suited for registered ECC DDR5 servers

This memory fits servers that require registered ECC DDR5 RDIMMs in a 288-pin form factor with a 2Rx4 rank configuration at 5600 MT/s. It is not for systems that accept only unbuffered UDIMMs or SODIMMs. Builders needing non-ECC memory or a different voltage should look elsewhere. Always verify the motherboard's qualified vendor list and population rules before purchase.

2Rx4 rank decides full-capacity operation

The 2Rx4 dual-rank organization determines whether the memory controller can address the full 128GB per module at the rated 5600 speed. A mismatched rank structure can limit capacity or prevent the system from booting. Check the H13SSL-N manual for approved DIMM population order and maximum supported capacity per slot.

Questions about this item

Will the CL46 latency become a bottleneck when the Supermicro H13SSL-N runs memory-intensive workloads continuously?

CL46 is the rated CAS latency at DDR5 5600; the registered buffer offloads the controller so all slots can stay populated at full speed without timing degradation.

How much heat does a 128 GB 1.1 V DDR5 RDIMM generate when the server runs 24/7, and is a heat spreader needed?

The module operates at 1.1 V without a heat spreader; registered architecture reduces electrical load per pin, keeping thermals within standard server airflow limits.

Does the Supermicro H13SSL-N require any specific BIOS setting or firmware version to recognise this 2Rx4 128 GB kit at 5600 MT/s?

The board must support 288-pin DDR5 RDIMM at 5600 with 2Rx4 organisation; consult the motherboard manual for population order and any required BIOS revision.
