256GB DDR4 ECC RDIMM kit for ThinkMate towers

This registered ECC memory kit delivers 256 GB across four 64 GB modules built for ThinkMate TWX‑XS8 tower servers. It targets administrators who need maximum supported capacity for virtualization or database workloads.

DDR4 3200 registered ECC limits

The DDR4 3200 interface tops out at PC4‑25600 bandwidth with CL22 latency and 1.2 V operation. Registered buffering adds one cycle of command delay, and the 4Rx4 organisation restricts maximum rank‑per‑channel density on many server platforms.

Bare modules with 288‑pin RDIMM connectors

No heat spreaders are fitted, so airflow across the PCB is essential in densely populated chassis. The standard 288‑pin RDIMM keying prevents insertion into UDIMM or LRDIMM slots, and the four‑module kit fills all channels on compatible two‑socket boards.

Questions about this item

Should I choose the 4×64GB kit or a different capacity for my ThinkMate TWX-XS8 server?

The kit provides 256GB total across four 64GB modules, filling four slots with 4Rx4 registered ECC DDR4 3200 memory.

What does the 3200 speed rating deliver in a ThinkMate TWX-XS8-24S3 tower?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V, matching the server's supported memory bus.

Will the 288-pin RDIMM interface work with the ThinkMate TWX-XS8-14S3 motherboard?

Yes, the 288-pin DDR4 RDIMM form factor with registered ECC and 4Rx4 organisation is the specified type for those ThinkMate towers.
