128 GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit provides 128 GB of DDR5 4800 registered ECC memory across four 32 GB modules. It is built for the THINKMATE VSX-R5-760RTP7 workstation and runs at 1.1 V with CL40 latency. The 288-pin RDIMM form factor fits compatible server and workstation motherboards requiring registered error-correcting modules.

Suited for VSX-R5-760RTP7 upgrades

IT professionals expanding the THINKMATE VSX-R5-760RTP7 will match the factory memory specification exactly. Builders needing unbuffered UDIMMs, non-ECC memory, or a different pin count should select another product. The kit is not intended for consumer desktop boards that lack registered ECC support.

Registered ECC RDIMM requirement

The single specification that decides fit is the motherboard's need for 288-pin DDR5 registered ECC RDIMMs at 4800 MT/s. If the target system requires unbuffered memory, a different voltage, or a lower speed grade, this kit will not function correctly.

Questions about this item

How much power does the 1.10V DDR5 4800 kit draw when the workstation runs continuously?

Each module operates at 1.10V, the standard DDR5 voltage, so total power scales with the 128GB capacity and the server platform's memory controller efficiency.

What motherboard features are required for the 288-pin ECC RDIMM kit to function?

The board must provide 288-pin DDR5 RDIMM slots, support registered ECC memory, and accept 2Rx8 modules at 4800 MT/s with CL40 timing.

Can the 4800 MT/s CL40 modules share channels with slower DDR5 RDIMMs already installed in the Thinkmate?

The memory controller will clock all populated slots to the lowest common speed and latency, so mixing with slower DDR5 RDIMMs reduces the kit to that lower rate.
