32 GB DDR4 ECC UDIMM kit

This 32 GB kit contains two 16 GB DDR4 3200 CL22 ECC unbuffered UDIMM modules. It is built for Supermicro X12 series server and workstation boards that accept 288-pin DDR4 ECC memory. The modules run at 1.2 V and use 2Rx8 organisation with major-brand DRAM chips.

Compatibility and use cases

Suitable for administrators upgrading supported Supermicro platforms that require DDR4 ECC unbuffered memory. Not suited for systems that need registered or load-reduced DIMMs, for boards limited to lower speeds, or for any platform that does not accept 288-pin DDR4 ECC UDIMMs.

Deciding specification: DDR4 3200 CL22 ECC

The memory operates at DDR4 3200 with CL22 latency and ECC error correction in an unbuffered layout. This combination determines whether the kit will post and run stably in the target Supermicro motherboards; verify the board's qualified-vendor list before purchase.

Questions about this item

Which Supermicro motherboards must I already have for this 288-pin DDR4 ECC UDIMM kit to be supported?

The kit is validated for Supermicro X12SAE-5, X12SCA-5F, X12STD-F, X12STE-F, X12STH-F, X12STH-LN4F and X12STH-SYS boards.

Will the 3200 MHz CL22 modules run stably beside older DDR4 sticks I keep in the same server?

Mixing speeds or latencies forces all channels to the slowest common timing; for best stability populate every slot with identical 3200 CL22 modules.

How can I confirm the 32 GB kit is operating at 3200 MT/s with ECC active after installation?

Check the BIOS memory information screen — it should report 3200 MT/s, CL22 timings, 1.20 V and ECC enabled for each 16 GB module.
