512GB DDR5 4800 ECC RDIMM Kit

This NEMIX RAM kit provides 512GB of DDR5 memory across eight 64GB registered DIMMs. It runs at 4800 MT/s with CL40 latency and operates at 1.10V. The modules are 2Rx4 ECC RDIMMs designed for compatible Thinkmate SuperServer systems.

Suited for Thinkmate 611C-TN4R

This memory is built for the listed Thinkmate SuperServer platforms requiring registered ECC DDR5. Builders using consumer motherboards, workstations needing unbuffered UDIMMs, or systems that cannot accept registered modules should choose a different product.

288-pin DDR5 RDIMM form factor

The kit uses the standard 288-pin DDR5 RDIMM interface, which physically and electrically differs from UDIMM and previous DDR generations. Verify that your server board supports registered ECC DDR5 before purchasing.

Questions about this item

Will the 4800 MHz DDR5 RDIMM kit run alongside slower DDR5 modules I already have in my Thinkmate server?

All installed DDR5 modules will operate at the speed of the slowest module, so mixing speeds is possible but reduces overall throughput.

How can I confirm the ECC registered modules are functioning correctly after installation?

Enter the BIOS or UEFI and verify that the full 512 GB capacity is reported with ECC active at CL40 timings.

Does the package include anything besides the eight 64 GB RDIMMs?

The kit contains only the eight 288-pin DDR5 ECC registered modules; no heat spreaders, cables or tools are supplied.
