Supermicro MEM-DR412L-SL01-ER29 128GB DDR4 2933 ECC Registered server RAM

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.
