Compatible Supermicro Server Memory

This 16GB DDR4 2933MHz ECC Registered RDIMM is built for Supermicro motherboards X11DSN-TS, X11OPi-CPU, X11QPH+, X11QPL and X11SPA-T. It targets administrators upgrading workstations, servers or NAS systems that require registered memory with error correction. The module operates at 1.2V with CL21 latency and a 2Rx8 rank configuration. It will not work in standard desktop computers or alongside unbuffered DIMMs.

JEDEC Compliant Registered Design

The registered buffer reduces electrical load on the memory controller, allowing larger total capacities in multi-slot server boards. ECC circuitry detects and corrects single-bit errors to protect data integrity in critical workloads. JEDEC and RoHS compliance ensures a warranty-safe upgrade path for the listed Supermicro platforms. No heat spreader is fitted, so airflow in dense chassis remains unimpeded.

16GB Capacity With Backward Speed Support

Each DIMM provides 16GB of capacity at the rated 2933MHz speed, and will also run at 2666MHz, 2400MHz or 2133MHz when installed in slower systems. This headroom suits virtualisation hosts, database nodes or file servers that benefit from maximum registered DIMM populations. Builders needing unbuffered memory, desktop compatibility or speeds above 2933MHz must choose a different module type.

Questions about this item

Will the 2Rx8 registered DIMM need any firmware updates or periodic re-seating during its service life?

No firmware updates or scheduled re-seating are required; the module is a standard JEDEC DDR4 2933MHz CL21 1.2V registered ECC DIMM that operates without user maintenance once installed in a compatible Supermicro X11 board.

What electrical or thermal limit will appear first when the module runs continuously at 2933MHz in a populated server chassis?

The 1.2V DDR4 specification and registered buffer keep power draw within JEDEC limits, so the first constraint under sustained load is typically the platform memory-controller thermal budget rather than the DIMM itself.

How much heat and acoustic noise does the bare 288-pin module add when the system runs 24/7?

The module has no heat spreader and no moving parts, so it contributes only the nominal DDR4 1.2V heat load and zero acoustic noise; overall chassis thermals and fan speed remain governed by the server platform design.
