System-specific memory kit

This NEMIX RAM kit delivers 512GB across four 128GB DDR4 3200 modules built for ThinkMate VSX-R5-760S1 and VSX-R5-540RTP workstations. ECC registered RDIMM design targets IT teams running virtualization, databases or rendering workloads that demand data integrity.

Capacity and headroom

The 512GB total provides substantial headroom for large in-memory datasets, multi-tenant containers or heavy compile farms. Four 4Rx4 ranks per module maximise density on supported boards; systems limited to fewer ranks or lower speeds will not utilise the full capacity.

Upgrade path

This kit replaces lower-density RDIMM sets or mixed-capacity populations that limit channel bandwidth. The jump is worth it when workloads exceed 256GB and the platform qualifies 128GB 4Rx4 modules at 3200 MT/s.

Questions about this item

Will these 4Rx4 DDR4 3200 ECC RDIMMs run alongside the 2Rx4 modules already in my Thinkmate VSX-R5-760S1?

Mixing 4Rx4 and 2Rx4 ranks on the same channel is not supported by the platform; populate all four slots with this matched 512 GB kit for stable operation.

How can I confirm the kit is running at the rated 3200 MT/s CL22 after installation?

Enter the BIOS or use a tool such as dmidecode to verify each DIMM reports DDR4-3200, 1.20 V, CAS 22 and ECC registered mode.

Does the package include the four 128 GB RDIMMs only, or are mounting brackets or cables also supplied?

The box contains the four 288-pin DDR4 128 GB ECC RDIMM modules; no brackets, cables or additional hardware are included.
