OWC 4GB DDR4 2133MHz CL15 1.2V 288pin Non-ECC UDIMM memory upgrade

SKU CH-1DA8-DA0P0

4GB DDR4 2133MHz CL15 UDIMM upgrade for HP ProDesk 400 G3, 490 G3 and 600 G2 desktops

  • Capacity4GB
  • Type288-Pin DDR4 Non-ECC UDIMM
  • SpeedDDR4 2133 (PC4 17000)
  • CAS LatencyCL15
  • Voltage1.2V
  • ECCNo
  • 4GB capacity lets you run more applications simultaneously
  • DDR4 2133MHz speed with CL15 latency delivers responsive system performance
  • 2V low-voltage operation reduces power consumption and heat
  • 288-pin UDIMM form factor fits HP ProDesk 400 G3, 490 G3 and 600 G2 desktops
  • JEDEC and RoHS compliant for a warranty-safe upgrade

Targeted HP ProDesk Upgrade

This 4 GB DDR4 2133 MHz CL15 module is built for HP ProDesk 400 G3 SFF, 400 G3 Tower, 490 G3, 600 G2 SFF and 600 G2 Tower systems. It suits owners who need a straightforward capacity increase for everyday multitasking. Buyers whose machines require ECC or registered memory will not be served by this non-ECC unbuffered DIMM.

Simple Slot-In Installation

The 288-pin UDIMM drops into a standard DDR4 desktop slot and runs at 1.2 V with no extra configuration. Alignment notches prevent backward insertion, and the lack of a heat spreader keeps the profile low for tight SFF chassis. The main risk is exceeding the board’s maximum supported capacity per slot, which this module does not guarantee.

Verify Slot Count And Maximum Capacity

Confirm how many DIMM slots your specific ProDesk model provides and what total memory the motherboard and BIOS will accept. The 1Rx8 organisation works with typical consumer chipsets, but some OEM boards limit rank population per channel. Check the system manual or vendor documentation before ordering.
