768GB DDR5 ECC RDIMM Kit

This 768GB kit contains six 128GB registered DDR5 modules built for THINKMATE HDX-QN8-52E4 high-density servers. Each module runs at 4800MHz with CL40 latency at 1.10V and uses 4Rx4 organisation. The ECC registered design targets IT professionals who need maximum capacity and data integrity in compatible Thinkmate platforms.

Six-Module Population Fills Six Slots

The package delivers exactly six 288-pin RDIMMs so you can populate six memory channels in a single order. Using major OEM Samsung Micron or Hynix components the modules are stress-tested under load before shipping. No heat spreaders are fitted which keeps the form factor standard for dense server boards.

Verify Six-Slot Support and 4Rx4 Compatibility

Before ordering confirm that your Thinkmate HDX-QN8-52E4 motherboard provides six DDR5 RDIMM slots and accepts 4Rx4 registered modules at 4800MHz. Check the system manual for maximum capacity per slot and population rules for 768GB total. This kit is not for systems limited to fewer slots or lower rank configurations.

Questions about this item

Will the 4Rx4 registered DIMMs need any firmware updates or rank-sparing configuration changes during their service life?

The modules are factory-tested DDR5 4800 CL40 1.10V ECC RDIMMs; no firmware updates or rank-sparing changes are required after installation.

Which electrical or thermal limit is reached first when all six 128 GB sticks run continuously at 4800 MT/s?

The 1.10 V operating voltage and CL40 latency define the power envelope; the memory controller's thermal throttle point will be reached before any module-level limit.

How much additional heat does the 768 GB kit generate inside a THINKMATE HDX-QN8-52E4 chassis during all-day operation?

Each 1.10 V RDIMM draws only its rated DDR5 power; the registered buffer adds minimal overhead, so total heat rise stays within the server's standard cooling design.
