64GB DDR5 4800 ECC RDIMM kit

This 64GB kit contains four 16GB DDR5 4800 modules built to the PC5-38400 standard with CL40 latency and 1.10V operation. Each stick is a 288-pin ECC registered DIMM using 1Rx8 organisation and chips from major OEM suppliers. The memory is validated for ThinkMate STX-NL-QE16 E4 nearline storage servers.

Suited for ThinkMate server upgrades.

System administrators expanding a ThinkMate STX-NL-QE16 E4 will match the exact registered ECC specification required by that platform. Builders using consumer desktop motherboards or workstations that accept only unbuffered non-ECC DIMMs cannot use this kit because the registered buffer and ECC logic are electrically incompatible with those memory controllers.

Registered ECC RDIMM form factor decides fit

The single specification that determines compatibility is the registered ECC RDIMM design on a 288-pin DDR5 interface. Only systems whose memory controller and BIOS explicitly support registered ECC DDR5 at 4800 MT/s with 1Rx8 ranking will recognise and stabilise these modules.

Questions about this item

Will the 288-pin DDR5 modules need any thermal maintenance since they ship without a heat spreader?

The modules operate at 1.10 V without a heat spreader; ensure the server chassis provides adequate airflow over the DIMM slots for continuous operation.

What throughput ceiling appears first when the 4800 MT/s kit runs sustained workloads?

The PC5-38400 rating and CL40 latency define the maximum sustained bandwidth the four 1Rx8 modules can deliver.

How much power and heat does the 64 GB kit produce when the server runs all day?

At 1.1 V the four 16 GB registered DIMMs draw low power, and ECC RDIMM operation adds minimal thermal load inside the Thinkmate chassis.
