128GB DDR5-4800 ECC RDIMM kit

This NEMIX RAM kit provides 128GB of DDR5 server memory across four 32GB registered DIMMs. It operates at 4800MT/s with CL40 latency and 1.10V. ECC and registered buffering protect data integrity in Thinkmate Supermicro SuperServer 611C-TN4R and 621C-TN12R systems.

Suited for Thinkmate server upgrades needing

Administrators expanding memory in the listed Thinkmate SuperServer models will find this 4×32GB kit a direct fit. Builders using consumer motherboards, non-Thinkmate platforms or systems requiring unbuffered UDIMMs should look elsewhere because this kit is registered ECC RDIMM only.

Registered ECC RDIMM form factor decides fit

The 288-pin DDR5 RDIMM modules are electrically and mechanically incompatible with UDIMM slots found in desktop and workstation boards. Verify the target server accepts registered ECC memory before purchase; the registered buffer and ECC function will not work in unbuffered slots.

Questions about this item

How do I install the 288-Pin DDR5 RDIMM modules and which step is often missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until both latches click, then verify in BIOS that all 128GB are detected at 4800 MT/s with ECC active.

What maintenance or replacement will this registered ECC kit need over time?

No scheduled maintenance is required; the modules have no heat spreaders to clean and ECC corrects single-bit errors on the fly, so replacement only occurs if a module fails, which is covered by the lifetime replacement warranty.

What limit appears first under sustained load with these CL40 1.1V modules?

The CAS latency of CL40 at 4800 MT/s sets the timing ceiling; sustained workloads will hit this latency bound before voltage or thermal limits become a factor.
