512 GB DDR5 ECC RDIMM kit

This 512 GB kit contains four 128 GB DDR5 registered DIMMs built for the Thinkmate VSX-R5-760RTP7 workstation. ECC and registered operation protect data integrity in multi-socket server workloads. The modules run at DDR5 4800 with CL40 latency at 1.1 V. IT teams specifying memory for this platform can deploy the kit without further qualification.

Capacity and headroom at 512 GB

Four 128 GB ranks deliver 512 GB total, filling four slots on compatible Thinkmate boards. The 4Rx4 organisation and PC5-38400 bandwidth support large in-memory databases and virtualisation densities. Workloads that exceed 512 GB or require higher frequencies than 4800 MT/s will need a different configuration.

Build integration for Thinkmate workstations

The 288-pin DDR5 RDIMM form factor installs directly into the VSX-R5-760RTP7 memory slots with no heat spreader to clear. Registered buffering reduces electrical load on the memory controller, freeing headroom for fully populated channels. Systems requiring unbuffered UDIMMs or non-ECC memory cannot use this kit.

Questions about this item

Will this 512GB DDR5 4800 ECC RDIMM kit work in a THINKMATE VSX-R5-760RTP7 alongside any existing modules?

This kit is validated for the THINKMATE VSX-R5-760RTP7 workstation; install all four 128GB modules together for the supported 512GB configuration.

How can I verify the 4Rx4 CL40 registered ECC modules are operating correctly after installation?

Enter the system BIOS or UEFI and confirm the memory reports 512GB at DDR5 4800 with ECC active and CAS latency 40.

Does the package include only the four 288-pin RDIMMs or are any cables or tools also supplied?

The box contains the 512GB kit (4×128GB DDR5 4800 ECC RDIMM modules) only; no cables, heat spreaders or tools are included.
