NEMIX RAM 128GB DDR5 4800 ECC RDIMM Kit

This 128GB kit contains two 64GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It is built for THINKMATE TWX-XS8 tower servers that require PC5-38400 registered memory. The modules operate at 1.10V and use 2Rx4 organisation on 288-pin connectors.

Suited for ThinkMate TWX-XS8 server upgrades

Administrators expanding memory in a TWX-XS8-24S4 or TWX-XS8-14S4 will match the factory specification exactly. Builders needing unbuffered UDIMMs, non-ECC modules, lower capacities or faster speeds than 4800 MT/s must select a different product line.

Registered ECC with 2Rx4 organisation

The 2Rx4 rank layout and registered buffer are the decisive compatibility factors for these ThinkMate platforms. A module with a different rank structure or without the register will not function in the target server.

Questions about this item

Should I pick the 128GB kit or a different capacity for my THINKMATE server?

This kit provides 128GB total capacity using two 64GB modules; choose it when your workload needs that full amount and the server has two available DDR5 RDIMM slots.

What does DDR5 4800 CL40 mean for real-world server responsiveness?

The modules run at 4800 MT/s with a CAS latency of 40 cycles, giving registered ECC throughput suited for multi-threaded server workloads on the TWX-XS8 platforms.

How does the DDR5 RDIMM interface limit performance in this system?

The 288-pin DDR5 RDIMM interface operates at 1.1V with registered buffering and 2Rx4 organisation, so the memory controller on the THINKMATE board governs the maximum usable speed.
