Simmtec, Inc 1CA76AT 16GB DDR4 2400MHz UDIMM

16GB DDR4-2400 UDIMM for desktop upgrades

This 16GB DDR4-2400 UDIMM module provides a straightforward capacity increase for compatible desktop systems. It operates at the PC4-19200 standard with a low 1.2V voltage. The non-ECC unbuffered design suits standard consumer motherboards. It is built from major-brand components such as Samsung, SK Hynix, or Micron.

DDR4-2400 speed ceiling and non-ECC limit

The module runs at a fixed 2400MHz data rate, so the memory subsystem cannot exceed this bandwidth. The non-ECC architecture means single-bit errors are not corrected in hardware. Mixing with faster DDR4 modules will force the entire array down to 2400MHz. The 2Rx8 organisation is a physical constraint of this specific stick.

Replaces slower or smaller DDR4 sticks

Swapping an 8GB or lower DDR4 module for this 16GB unit doubles capacity in that slot. The upgrade is worthwhile when the platform supports DDR4-2400 and the workload benefits from additional memory. Identically matched modules are supplied to avoid timing mismatches. The part is validated as a direct equivalent to OEM part number 1CA76AT.
