Capacity & fit

This kit supplies 384 GB of DDR4 memory in six 64 GB registered DIMMs built for ThinkMate VSX-R5-760S1 and VSX-R5-540RTP workstations. IT teams ordering for those exact platforms can fill all slots with a single part number. Buyers with other motherboards or consumer desktops cannot use these modules.

Platform verification

Confirm that your system accepts 288-pin DDR4 RDIMMs running at 3200 MT/s with a 4Rx4 organisation and 1.20 V operation. The modules are ECC registered, so the board must support registered ECC memory; unbuffered or non-ECC platforms will not post. Check the vendor documentation for maximum supported capacity per slot before ordering.

Kit contents

The package delivers six matched 64 GB sticks tested together for the target ThinkMate models, removing the guesswork of mixing separate kits. No heat spreaders are included, so airflow in the chassis must handle bare modules. No software, drivers or additional accessories are bundled with the memory.

Questions about this item

Does the 384GB kit ship as six 64GB modules or must I buy them individually?

The package contains six 64GB RDIMMs in a single kit, so no additional modules are required.

Should I select the CL22 3200MHz version or a different latency for the ThinkMate VSX-R5-760S1?

This kit is specified at CL22 3200MHz and is validated for the ThinkMate VSX-R5-760S1 and VSX-R5-540RTP workstations.

What does the 4Rx4 rank mean once the memory is installed in the server?

Each 64GB module uses a 4Rx4 organisation, giving the memory controller four logical ranks per DIMM for high-density capacity.
