  • CAS LatencyCL15
  • Voltage1.2V
  • ECCNo
  • 16 GB capacity for smoother multitasking

HP ProDesk 400 G3 490 G3 600 G2 compatible DDR4

This 16GB DDR4 2133MHz CL15 module is built for HP ProDesk 400 G3 SFF, 400 G3 Tower, 490 G3, 600 G2 SFF and 600 G2 Tower systems. It delivers a straightforward capacity increase for everyday office workloads. The unbuffered non-ECC design matches the factory memory specification for these platforms.

Capacity headroom for multitasking and larger files

The 16GB capacity lets you keep more applications and larger documents open simultaneously without hitting the system limit. Performance scales smoothly until the memory ceiling is reached, at which point the OS must swap to storage.

JEDEC compliant upgrade

The module meets JEDEC standard specifications and is ROHS compliant, ensuring a warranty-safe installation. OWC provides a limited lifetime warranty with free technical support and an advanced replacement programme. No heat spreader is included, keeping the profile low for small form factor chassis.

Questions about this item

Will the 16GB DDR4 2133MHz CL15 1.2V 288pin UDIMM run alongside my existing DDR4 2133MHz sticks in an HP ProDesk 400 G3 SFF?

Yes — the module is JEDEC-standard DDR4 2133 PC4-17000 CL15 1.2V unbuffered non-ECC, so it will match the speed and timing of identical DDR4 2133MHz memory already installed in the ProDesk 400 G3 SFF.

How can I confirm the 16GB DDR4 2133MHz CL15 1.2V 288pin UDIMM is recognised at full speed after installation?

Enter the BIOS or use CPU-Z; the memory should report 16GB capacity, DDR4 2133MHz (PC4-17000) and CAS latency 15 at 1.2V.

Does the 16GB DDR4 2133MHz CL15 1.2V 288pin UDIMM ship with a heat spreader or any tools, or must I buy them separately?

The module has no heat spreader and no tools are included; only the UDIMM itself is in the box.
