Server memory kit

This NEMIX RAM kit supplies 512GB across eight 64GB DDR5 modules built for THINKMATE SuperServer 421GE-TNRT and 421GE-TNRT3 systems. Registered ECC RDIMM construction delivers error correction and signal integrity required by enterprise workloads.

CL40 4800MHz registered DIMMs

Each module runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.10V using 2Rx4 organisation on 288-pin DDR5 form factor. Major OEM Samsung, Micron or Hynix chips are stress tested under load to verify stability in multi-socket server boards.

Suited for capacity-bound servers

IT teams expanding memory in compatible THINKMATE SuperServer platforms gain maximum density per channel without mixing kits. Builders needing non-ECC, unbuffered DIMMs or different speeds should select memory matched to their motherboard specifications.

Questions about this item

Will the 2Rx4 DDR5 RDIMM modules need firmware updates or reconfiguration after installation?

The 8x64GB kit runs at DDR5 4800 CL40 with 1.10V; no firmware updates are required for the registered ECC modules themselves.

What limit appears first when the 512GB kit runs at DDR5 4800 continuously?

Sustained operation is bounded by the CL40 latency and 1.10V voltage at the rated 4800 MT/s speed.

How much heat and power do the eight 288-pin registered DIMMs produce under all-day load?

Each 64GB module operates at 1.10V DDR5 4800; the registered design and ECC add minimal overhead, so total heat scales with the 512GB capacity at that voltage.
