Server ECC Registered DIMM

This is a single 32GB DDR4 2400 PC4-19200 CL17 2Rx4 288-pin 1.2V VLP ECC Registered DIMM module. It is built for Supermicro SuperServer F628R3 series systems and will not work in standard desktop computers. The module uses registered buffering and ECC for data integrity in server workloads.

Build Integration Requirements

The VLP height allows installation in dense 1U and 2U chassis where standard DIMMs cannot fit. Registered signalling requires a motherboard chipset that supports registered memory; mixing with unbuffered or load-reduced modules is not supported. One module adds 32GB of capacity without occupying additional DIMM slots.

Suitable Use Cases

Suits administrators upgrading Supermicro F628R3-RC1B+, F628R3-RC1BPT+, F628R3-RTB+, F628R3-RTBN+ or F628R3-RTBPT+ servers. Not for desktop builders, gaming rigs or any platform that requires unbuffered non-ECC DDR4. Buyers needing higher per-slot density or different registered speeds should verify their motherboard qualification list.

Questions about this item

How many ranks does the 32GB DDR4 2400 CL17 module use and does that affect maximum capacity per channel?

The module is a 2Rx4 dual-rank design; each rank counts as one electrical load so a channel populated with dual-rank DIMMs reaches its rank limit with fewer modules than single-rank ones.

What is the operating voltage and does the VLP height change airflow or thermal limits in a 1U Supermicro SuperServer?

It runs at 1.2V and the very-low-profile height keeps it below the CPU heatsink clearance in 1U chassis, so standard front-to-back airflow handles the heat without extra cooling.

Which specific Supermicro SuperServer models must the system be to accept this ECC registered DIMM?

Compatible systems are Supermicro SuperServer F628R3-RC1B+, F628R3-RC1BPT+, F628R3-RTB+, F628R3-RTBN+ and F628R3-RTBPT+.
