128GB DDR4 ECC RDIMM for Thinkmate servers

This 128GB DDR4 3200 CL22 8Rx4 registered DIMM targets Thinkmate HDX QN24-52E3 QT24-32E3 QT24-52E3 XN12-32S3 XN12-52S3 workstations and servers. It will not fit standard desktop motherboards that require unbuffered memory.

JEDEC and RoHS compliant single module

The module meets JEDEC PC4-25600 specifications and RoHS requirements, delivering a warranty-safe upgrade. No heat spreader is fitted, and the 1.2V operating voltage matches server platform expectations.

8Rx4 rank density decides motherboard slot limits

The 8Rx4 organisation determines how many modules the memory controller can address per channel. Builders needing higher total capacity must verify the platform rank limit before ordering.

Questions about this item

Will the 128GB 8Rx4 registered DIMM need any firmware or thermal-pad maintenance over time?

No firmware updates or thermal-pad servicing are required; the module has no heat spreader and runs at standard 1.2V JEDEC voltage.

What electrical limit appears first when the 3200 MT/s CL22 module runs continuously at full load?

The 1.2V supply rail and the memory controller's maximum registered-DIMM rank count are the first constraints under sustained throughput.

How much heat and power does a single 128GB 288-pin ECC RDIMM produce during all-day server operation?

At 1.2V the module draws only a few watts and, lacking a heat spreader, relies on chassis airflow to stay within normal DDR4 thermal limits.
