Targeted Server Upgrade

This 32GB DDR4 ECC Registered RDIMM is built for Supermicro X11SRi-IF, X11SRL-F, X11SRM-F and X11SRM-VF motherboards. It serves administrators extending the life of existing server infrastructure or assembling new workstation and NAS systems. The module is not compatible with standard desktop computers and cannot be mixed with unbuffered memory.

Capacity and Speed Limits

The single module delivers 32GB of capacity at a 2933MHz data rate with CL21 latency and 1.2V operation. It provides headroom for multi-threaded workloads and virtualization tasks that benefit from registered ECC integrity. The module will downclock to 2666MHz, 2400MHz or 2133MHz when the platform requires a lower speed, but it cannot exceed the rated 2933MHz frequency.

Build Integration

Installation requires a 288-pin DDR4 slot wired for registered ECC signalling and a platform that supports 2Rx4 organisation. The module lacks a heat spreader, so chassis airflow must be adequate for sustained server loads. Using this memory frees budget compared to original Supermicro part numbers such as MEM-DR432LC-ER29 while maintaining full JEDEC and RoHS compliance.

Questions sur cet article

Will this 2933 MHz CL21 module run stably alongside my existing 2400 MHz DDR4 ECC registered DIMMs?

The module is backward compatible with 2133 MHz, 2400 MHz and 2666 MHz speeds, so it will operate at the lowest common speed when mixed with slower ECC registered DIMMs.

How can I confirm the ECC registered function is active after installation?

The BIOS memory information screen and operating-system tools such as dmidecode will report ECC type as registered and show the running speed and timings.

Does the 288-pin RDIMM come with a heat spreader or any extra accessories?

The module has no heat spreader and ships as a single 32 GB DIMM; no cables, brackets or additional components are included.
