Exact-match DDR4 upgrade

This 16GB DDR4-2933 (PC4-23400) module is built for desktop systems that require a single-rank 1Rx8 Non-ECC UDIMM at 1.2V. It uses the precise timing and voltage the memory controller expects so the full capacity is recognised at the rated speed.

Replaces slower or smaller DIMMs

Upgrading from lower-capacity or slower DDR4 sticks is worthwhile when the motherboard supports DDR4-2933 and the existing configuration leaves free 288-pin slots. The jump adds bandwidth and capacity without changing voltage or form factor.

Check motherboard manual first

Verify that the Supermicro X12SCZ-F or X12SCZ-TLN4F board accepts 16GB Non-ECC UDIMMs in the planned slot order and that the BIOS is current enough to initialise the modules at CL21. Confirm the system does not require ECC or registered memory before ordering.

Questions about this item

Will this 288-pin DDR4 UDIMM fit the memory slots on my Supermicro X12SCZ-F motherboard?

Yes, the module is a 288-pin DDR4 UDIMM, which is the exact form factor required by the Supermicro X12SCZ-F and X12SCZ-TLN4F motherboards.

What is the correct way to install this 1Rx8 UDIMM, and what step do people often miss?

Align the notch on the module with the slot key, press down firmly until both side clips click shut, then consult your motherboard manual for the approved DIMM population order.

Does this non-ECC DDR4 module need any firmware updates or component replacements over its lifetime?

No, the memory has no firmware and no moving parts; it is a passive component that does not require updates or scheduled replacements.
