Two green DDR5 RDIMM modules without heat spreaders, 288-pin, 32GB kit

NEMIX RAM

NEMIX RAM 32GB (2x16GB) DDR5 5600 CL46 ECC RDIMM Lenovo ST650 V3

SKU CH-7J3B-JHW9S

Adds 32 GB of DDR5 ECC registered memory at 5600 MT/s CL46 in a 2 × 16 GB kit for the Lenovo ThinkSystem ST650 V3 tower server

  • ECC protection detects and corrects data errors in real time
  • Registered buffering stabilises signals for reliable 32GB capacity
  • DDR5 5600 speed delivers high bandwidth for demanding workloads
  • 1V operation reduces power consumption per module
  • Validated for Lenovo ThinkSystem ST650 V3 tower server

Server-grade DDR5 ECC RDIMM kit

This 32 GB kit contains two 16 GB registered DDR5 modules rated at 5600 MHz with CL46 latency. Error-correcting code and registered signalling protect data integrity in the Lenovo ThinkSystem ST650 V3 tower server. The 1.1 V operating voltage matches the platform specification.

Upgrade from non-ECC or slower DDR5

Replacing unbuffered or lower-speed memory adds error detection and the bandwidth of PC5-44800. The jump is worth it when the ST650 V3 workload demands registered DIMMs and the higher throughput of DDR5 5600 for virtualisation or database tasks.

32 GB capacity with 1Rx8 organisation

Two single-rank modules provide 32 GB of addressable memory for multi-VM deployments and large dataset caching. Headroom ends when the application working set exceeds the installed capacity or the memory controller reaches its maximum supported DIMM count.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots in my Lenovo ThinkSystem ST650 V3 tower server?

Yes, this kit is built specifically for the ST650 V3 and uses the standard 288-pin DDR5 RDIMM form factor that matches the server's DIMM slots.

What is the correct way to seat the two 16 GB modules, and what step do installers often miss?

Align each module's notch with the slot key, press firmly until both side clips click, then verify in the BIOS that both 16 GB sticks are detected at 5600 MT/s.

How can I tell later if one of the ECC RDIMMs has developed a fault?

The server's management controller logs correctable ECC errors; a rising count on either 1Rx8 module signals it should be replaced.
