System Specific Memory Kit

This NEMIX RAM kit provides 512GB of DDR5 memory across four 128GB registered ECC RDIMMs. It operates at 4800MHz with CL40 latency and 1.1V power draw. The modules use a 288-pin form factor and 2Rx4 rank organisation for full-capacity recognition on the target platform.

Who Should Buy This

Server administrators upgrading a Supermicro H13SST-G motherboard will receive the exact rank, voltage, and timing the board's memory controller expects. Builders needing unbuffered UDIMMs, SODIMMs, non-ECC memory, or lower capacities should select a different kit.

Deciding Specification

The registered ECC RDIMM architecture with 2Rx4 organisation is the single specification that determines compatibility; the motherboard requires this buffered design to run all slots fully populated at rated speed.

Questions about this item

Does my motherboard need registered DDR5 slots for this kit?

Yes, the 288-pin DDR5 RDIMM modules only fit motherboards wired for registered DDR5 memory such as the Supermicro H13SST-G

Can I mix these 2Rx4 modules with other ranks in the same server?

Mixing ranks is not recommended; the board's memory-population rules expect identical 2Rx4 registered DIMMs for full 512GB capacity at DDR5-4800

How do I confirm the kit runs at 4800 MT/s with CL40 after installation?

Check the BIOS memory information or OS tools such as dmidecode; they should report DDR5-4800, PC5-38400, 1.1 V and CL40 timings
