SuperMicro 2933 MHz DDR4 Kit

This 32 GB kit contains two 16 GB unbuffered UDIMMs built for the SuperMicro MBD-C9Z490-PG motherboard. Modules run at DDR4 2933 with CL21 latency at 1.2 V. The 288-pin DIMMs use major OEM Samsung, Micron or Hynix chips and ship as a matched pair for dual-channel operation.

Builders upgrading that specific board

The kit targets owners of the SuperMicro MBD-C9Z490-PG desktop or workstation platform who need a straightforward capacity increase. Systems requiring ECC, registered modules, speeds above 2933 MHz or capacities beyond 32 GB will not be served by this product.

32 GB dual-channel capacity

Two ranks of 1Rx8 memory deliver 32 GB total, enough for typical workstation workloads and moderate multitasking. Headroom ends when applications demand more than 32 GB or require ECC error correction for data integrity.

Questions about this item

What motherboard must I already own for this 288-pin DDR4 kit to be compatible?

The kit is validated for the SuperMicro MBD-C9Z490-PG motherboard.

Can I keep my existing DDR4 modules and add this 32 GB kit alongside them?

Yes, provided the board has free 288-pin slots and you match 1.2 V DDR4 2933 CL21 timing.

How do I confirm the 2x16 GB kit is running at 2933 MT/s after installation?

Check BIOS or CPU-Z — the memory tab should show DDR4-2933 (PC4-23400) at CL21 1.20 V.
