System-Specific DDR4 ECC RDIMM Kit

This 16 GB kit contains two 8 GB registered DDR4 modules rated at 3200 MT/s with CL22 latency. It is built for ThinkMate GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1 workstations that require ECC registered memory. The 1.2 V modules use a 288-pin form factor and 1Rx8 organisation.

No Heat Spreaders or Extra Software Included

The package supplies only the two memory modules without heat spreaders, cables, adapters or installation software. ECC and registered buffering are handled by the motherboard chipset, so no driver or utility is needed to activate error correction or stability features.

Straightforward DIMM Installation

Installation follows the standard 288-pin DDR4 slot procedure: power down, open the chassis, align the notch, press until the latches click, then close the case. The main risk is mixing these registered ECC modules with unbuffered non-ECC DIMMs, which prevents the system from posting. Always populate slots in the order specified by the workstation manual.

Questions about this item

Will the 1Rx8 ECC RDIMM modules need firmware updates or chip replacements during their service life?

No firmware updates or chip replacements are required for the 1Rx8 ECC RDIMM modules; they operate as installed for the lifetime of the system.

What limit appears first when the DDR4 3200 CL22 kit runs sustained workloads on the ThinkMate workstations?

The CL22 latency at 3200 MT/s sets the throughput ceiling before thermal or power limits are reached.

How much heat and power do the 1.2 V registered DIMMs produce when the workstation runs all day?

Each 8 GB module draws 1.2 V with no heat spreader, so total power stays low and airflow from the chassis handles the heat.
