Exact-match 32 GB DDR4-2933 UDIMM

This 32 GB DDR4-2933 (PC4-23400) module is built for desktop systems that require a 288-pin unbuffered non-ECC DIMM. It operates at 1.2 V with a CL21 latency and a 2Rx8 rank configuration using major OEM DRAM chips.

Builders upgrading Supermicro X12SCZ-F

The kit is validated for those specific motherboards and will not suit systems that need ECC registered modules, SODIMM form factors, or a different DDR generation. Buyers who want more capacity per slot or registered server memory should look at other options.

Verify manual for population rules

Check your motherboard manual for supported DIMM capacities, approved population order, and installation steps before ordering. Confirm the board accepts 2Rx8 unbuffered non-ECC UDIMMs at the rated speed and voltage.

Questions about this item

Does this 288-pin DDR4 UDIMM need an open DIMM slot on my Supermicro X12SCZ-F motherboard?

Yes — it installs in any free 288-pin DDR4 UDIMM slot on the X12SCZ-F or X12SCZ-TLN4F board.

Will this CL21 2Rx8 module run alongside my existing DDR4-2933 sticks?

It will; the board will train all modules to the lowest common speed and timing, so your current DDR4-2933 kit stays stable.

How do I confirm the kit is recognised at 32 GB and 2933 MT/s after install?

Check the BIOS memory summary or OS task manager — both should show 32 GB total capacity and a 2933 MT/s data rate.
