512GB DDR5 ECC RDIMM kit for Thinkmate servers

This 512GB kit contains four 128GB DDR5 4800 registered DIMMs built for Thinkmate GPX-QH12-12E4-2GPU servers. Each module runs at 1.1V with CL40 latency and 4Rx4 organisation. ECC and registered buffering protect data integrity in multi-socket workloads.

Four matched modules simplify large-capacity

The kit delivers 512GB in a single validated package so administrators populate all channels at once. Matched 4Rx4 ranks keep timing consistent across the memory subsystem. No extra software or accessories are included beyond the four DIMMs.

Bare modules with standard 288-pin DDR5 connectors

Samsung, Micron or Hynix DRAM chips sit on green PCBs without heat spreaders, relying on server chassis airflow. The 288-pin RDIMM edge connector fits Thinkmate DDR5 slots directly. Registered signalling reduces electrical load on the memory controller.

Questions about this item

Will the 4Rx4 registered ECC modules require any periodic firmware updates or component replacements during their service life?

No, DDR5 RDIMM memory has no firmware or moving parts; the modules are validated once at install and run without further maintenance.

What thermal limit appears first when the 4800 MT/s kit runs at full load continuously?

The 1.10 V DDR5 modules are rated for standard JEDEC operating temperatures; sustained loads stay within that envelope without throttling.

How much power does the 512 GB kit draw and how much heat must the server dissipate when all four 128 GB DIMMs run all day?

At 1.1 V each module draws only a few watts, so the entire 4 x 128 GB kit adds minimal heat to the chassis airflow.
