16GB DDR4-2400 UDIMM for desktop upgrades

This 16GB DDR4-2400 UDIMM module operates at 1.2V with a PC4-19200 speed rating. It uses a 2Rx8 organisation and non-ECC error handling for standard desktop platforms. The part is built to match OEM part number A9321912 using major brand components from Samsung, SK Hynix or Micron.

Simple UDIMM installation with OEM validation

Installation follows the standard UDIMM procedure of aligning the notch and pressing firmly until the retention clips engage. The module is 100% tested and validated for compatibility with the target OEM systems, reducing the risk of POST failures or instability. Matching modules are supplied for each order to avoid mixed-kit issues that can cause boot problems.

Suits desktops needing OEM-matched DDR4 expansion

This module suits users upgrading or repairing desktops that require DDR4-2400 non-ECC UDIMMs matching the A9321912 specification. Buyers who need ECC error correction, registered DIMM form factors, or speeds beyond DDR4-2400 should look at different memory types. Systems limited to lower DDR4 speeds or different voltage requirements will not support this module correctly.

Questions about this item

How can I confirm the module is running at DDR4-2400 after installation?

Check the memory speed in your system BIOS or a tool like CPU-Z; it should report 2400 MHz (PC4-19200) at 1.2 V.

What comes in the box and do I need anything else to install it?

The package contains the 16 GB UDIMM only; no extra cables, brackets or software are required — just a free DDR4 slot.

Should I choose this 16 GB stick or a different capacity for my upgrade?

This part is a single 16 GB module; add a second identical stick for dual-channel 32 GB or populate all slots for maximum capacity.
