32GB DDR4 ECC RDIMM Kit

This 32GB kit contains two 16GB DDR4 3200 registered DIMMs with ECC and a CL22 latency. It is built for Thinkmate GPX workstations that require registered memory for stable operation. The modules run at 1.2V and use a 2Rx8 organisation.

288-Pin Registered Installation

The 288-pin RDIMMs install in the same way as standard DIMMs but the registered buffer adds a small electrical load that some consumer boards cannot handle. A common issue is mixing registered and unbuffered modules, which prevents the system from posting. Always populate slots in the order shown in the workstation manual.

Thinkmate GPX Compatibility Check

Verify that your workstation is a GPX-WS-540RTP, GPX-WS-740RTP or GPX-WS-760S1 before ordering. These systems require DDR4 registered ECC memory and will not accept unbuffered or non-ECC modules. Confirm the motherboard supports 3200MHz operation and 2Rx8 density for the full 32GB capacity.

Questions about this item

How can I confirm the 32 GB kit is running at 3200 MT/s with CL22 after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 3200 MT/s and CAS latency reads 22; CPU-Z or dmidecode will also report DDR4-3200 CL22 on each 16 GB module.

What does the package contain and is anything else required for installation?

The box includes two 16 GB 288-pin DDR4 RDIMM modules (2Rx8, 1.20 V, ECC registered); no extra cables, brackets or software are needed — just open the chassis and seat the DIMMs.

Should I choose the 2Rx8 3200 CL22 version or a different speed or rank for my ThinkMate workstation?

This 2Rx8 DDR4-3200 CL22 kit (part MR25600-628K2) is validated for ThinkMate GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1; select it when your service manual specifies PC4-25600 registered ECC RDIMMs.
