32GB DDR4 2400 ECC RDIMM

This 32GB DDR4 2400 CL17 2Rx4 VLP ECC Registered DIMM is built for Supermicro SuperServer F628R3 series systems. It operates at 1.2V on a 288-pin interface and carries JEDEC-compliant PC4-19200 timing. The module is validated for the listed SuperServer models including F628R3-RTBPTN+, F628R3-RC1BPT+, F628R3-RTB+, F628R3-RTBN+ and F628R3-RTBPT+.

Suits servers needing registered ECC.

This memory fits workstations and servers that require registered ECC DDR4 modules. It will not work in standard desktop computers that use unbuffered non-ECC RAM. Builders who need load-reduced ECC or unbuffered ECC should look at different module types because this RDIMM cannot be mixed with those technologies.

Single 32GB module at CL17

A single module delivers 32GB of capacity at DDR4 2400 with CL17 latency, providing headroom for virtualization, database workloads and multi-application server tasks. Performance scales with the number of populated slots and the memory controller limits of the specific SuperServer chassis. The VLP form factor fits dense configurations where standard-height DIMMs would not clear.

Questions about this item

Does my Supermicro F628R3 server need any specific BIOS setting to recognise this 32GB DDR4 2400 CL17 2Rx4 VLP ECC RDIMM?

The module is JEDEC compliant at 1.2V and 2400 MT/s; most Supermicro F628R3 platforms detect it automatically, but check the server manual for any required memory-mapping or NUMA options.

Can I keep my existing Supermicro MEM-DR432LC-ER24 sticks and add this OWC 32GB DDR4 2400 CL17 2Rx4 VLP ECC RDIMM alongside them?

Yes, if the installed DIMMs are also DDR4 2400 ECC Registered 2Rx4 at 1.2V; mixing different ranks or unbuffered modules is not supported.

How can I confirm the 32GB DDR4 2400 CL17 2Rx4 VLP ECC RDIMM is running at the correct speed and ECC mode after installation?

Enter the server BIOS or use a tool like dmidecode; verify the module shows 2400 MT/s, CL17, 1.2V, ECC Registered and 32GB capacity.
