Speed 4800MHz

  • 64 GB kit installs as two matched 32 GB modules
  • DDR5-4800 speed runs at the server's rated frequency
  • Registered ECC design corrects single-bit errors on the fly
  • 1 V operation matches the board's voltage requirement
  • 288-pin RDIMM form factor fits the Supermicro H13SRH motherboard

Exact-match DDR5-4800 kit for Supermicro H13SRH

This 64 GB kit contains two 32 GB DDR5-4800 Registered ECC RDIMMs built to the 288-pin form factor. Each module runs at 1.10 V with CL40 timings and a 2Rx8 organisation. The specifications match the memory controller requirements of the Supermicro H13SRH motherboard so the system recognises the full capacity at rated speed.

Suited for admins expanding a verified H13SRH

The kit is intended for administrators who need to populate the Supermicro H13SRH with Registered ECC memory that meets the board's population rules. It is not for builders using consumer boards that accept only unbuffered UDIMMs, nor for laptops or workstations requiring SODIMM modules. Buyers needing different capacities or speed grades should consult the motherboard manual for approved configurations.

Straightforward installation when the manual is

The 288-pin RDIMMs seat in the standard server DIMM slots using the usual ejector-lever action. Most issues arise when the population order in the manual is ignored or when mixed ranks prevent the controller from training at full speed. Verifying the approved slot sequence before inserting the modules avoids the majority of boot-time recognition problems.

Questions about this item

What motherboard must I already own for this NEMIX RAM 64GB DDR5 4800 CL40 2Rx8 ECC RDIMM kit to work?

The kit is verified for the Supermicro H13SRH motherboard, which accepts 288-pin DDR5 Registered DIMMs at 1.10 V with CL40 timing and 2Rx8 organization.

How will these DDR5 4800 Registered ECC modules behave alongside older DDR5 RDIMMs I may keep in the same server?

All slots must run at the same speed and voltage; mixing different DDR5 speeds or registered and unregistered types will force the memory controller to down-clock or prevent boot, so match the 4800 MT/s CL40 1.10 V spec exactly.

How can I confirm the 64GB kit is running at its rated DDR5 4800 CL40 2Rx8 settings after installation?

Enter the BIOS or use a tool such as dmidecode to verify each DIMM reports 32 GB, 4800 MT/s, CL40 latency, 1.10 V, registered ECC and 2Rx8 rank configuration.
