128GB DDR4 2933 ECC Registered Module

This Supermicro server memory module delivers 128GB of DDR4 capacity at 2933 MT/s with ECC and registered buffering. It is built for enterprise platforms that require large memory footprints and data integrity. The 4Rx4 organisation and Samsung chipset support dense configurations in qualified systems. Buyers needing non-ECC or unbuffered DIMMs for consumer boards cannot use this module.

DDR4 2933 Bandwidth and Platform Limits

The PC4-23400 rating sets the maximum transfer rate at 2933 MT/s, so total throughput is bound by the memory controller and the number of populated channels. Registered signalling adds one clock cycle of latency versus unbuffered DIMMs, which the platform must account for. Quad-rank density restricts the number of modules per channel on many server chipsets, limiting total installable capacity. Systems that only support lower DDR4 speeds will downclock the module automatically.

288-Pin Registered Build and Daily Handling

The 288-pin DDR4 form factor fits standard server DIMM slots and operates at 1.20V for efficient power draw. Registered buffering reduces electrical load on the memory bus, allowing more modules per channel than unbuffered alternatives. ECC circuitry corrects single-bit errors and detects multi-bit errors during operation. The module is new and intended for installation in compatible server motherboards that explicitly support 4Rx4 registered ECC memory.

Questions about this item

Should I pick this 128GB 4Rx4 module or a lower-capacity alternative?

This module delivers 128GB in a single 288-pin DDR4 stick, so you reach high capacity with fewer slots; choose it when your board supports 4Rx4 registered DIMMs and you need maximum density per slot.

What does the DDR4 2933 (PC4 23400) rating mean once installed in a server?

The module runs at 2933 MT/s with a 1.20V supply, giving the bandwidth and latency specified by the PC4 23400 standard when the memory controller operates at that speed.

How does the 288-pin DDR4 ECC registered interface affect what the system can use?

The 288-pin DDR4 registered ECC interface requires a server platform that supports registered modules and ECC; it will not work in consumer boards that only accept unbuffered non-ECC memory.
