Server ECC RDIMM for Supermicro X10 boards

This 32GB DDR4 2400MHz registered module targets administrators upgrading or repairing Supermicro X10DAX, X10DDW-i, X10DDW-iN, X10DGO or X10DGO-T platforms. It delivers error-correcting, registered memory required by those server and workstation boards.

Registered ECC with 2Rx4 organisation

The single decisive spec is the registered ECC design with dual-rank x4 chips; standard desktop boards and unbuffered DIMMs will not work with this module. Compatibility is limited to the five listed Supermicro motherboards and equivalent server platforms that demand registered ECC DDR4.

32GB capacity at DDR4 2400 CL17

The module provides 32GB of addressable memory per slot at 1.2V, suitable for virtualization hosts, database nodes or NAS builds that fit within a single-DIMM limit. Workloads needing more than 32GB per channel or speeds above 2400MHz will exceed this module’s headroom.

Questions about this item

What does the 2400MHz speed mean for a Supermicro X10DAX server?

The module runs at DDR4 2400 (PC4-19200) with CL17 latency, delivering the rated bandwidth when the motherboard memory controller is set to 2400 MT/s.

How does the registered ECC interface affect compatibility?

Registered ECC RDIMM works only in server or workstation boards that support registered memory; it will not function in standard desktop systems and must not be mixed with unbuffered DIMMs.

What physical slot and clearance does the 288-pin RDIMM need?

It requires a standard 288-pin DDR4 DIMM socket; the module has no heat spreader, so it fits in tight server chassis without extra height clearance.
