256GB DDR4-3200 ECC RDIMM Kit

This 256GB kit contains two 128GB registered DIMMs built for ThinkMate rackmount servers. Each module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V. The 4Rx4 organisation and ECC registration target administrators who need maximum capacity per slot in compatible ThinkMate RAX-PT platforms.

Upgrading from lower-capacity RDIMMs

Replacing smaller registered modules with this 2x128GB kit doubles or quadruples per-slot density without changing voltage or speed. The jump is worthwhile when workloads such as virtualisation or in-memory databases hit the current memory ceiling and the server board supports 4Rx4 registered DIMMs at 3200 MT/s.

Tool-less DIMM installation

Installation follows the standard 288-pin RDIMM procedure: power down, open the chassis, release the slot latches, align the notch, and press until the latches click. Common issues include mixing registered and unbuffered DIMMs, exceeding the platform’s maximum rank count per channel, or populating slots in an order the firmware does not recognise.

Questions about this item

Will these 288-pin DDR4 RDIMMs fit the memory slots in a Thinkmate RAX-PT10-11A1 rackmount server?

Yes, the 288-pin DDR4 RDIMM form factor matches the DIMM slots on the listed Thinkmate RAX-PT10-11A1, RAX-PT8-12A1 and RAX-PT12-12A1 servers.

What is the correct way to seat the two 128 GB modules so the server recognises the full 256 GB?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until both retention clips click, then verify 256 GB in BIOS.

When should the ECC registered modules be replaced if correctable error counts start rising?

Monitor the platform's memory error logs; replace a module once correctable errors exceed the threshold recommended by the server vendor's maintenance guide.
