OWC 4GB DDR4 2400MHz CL17 1.2V 288pin UDIMM for HP Pavilion 570

SKU CH-XRA4-X5YBP

4GB DDR4 2400MHz CL17 1.2V UDIMM upgrades compatible HP Pavilion 570 desktops

  • Capacity4GB
  • Type288-Pin DDR4 Non-ECC UDIMM
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.2V
  • ECCNo
  • Designed for HP Pavilion 570 series desktops
  • 4GB DDR4 2400MHz CL17 module runs at 1.2V
  • JEDEC compliant for warranty safe upgrade
  • Backward compatible with 2133MHz systems
  • Unbuffered non-ECC 288-pin UDIMM for easy DIY install

Targeted upgrade for HP Pavilion 570 desktops

This 4GB DDR4 module is built to OEM specifications for HP Pavilion 570-p017na, 570-p018na, 570-p018nb, 570-p019na and 570-p019nb systems. It adds capacity to compatible desktops, workstations and NAS units that accept standard unbuffered UDIMMs. Buyers needing ECC error correction or registered server memory cannot use this kit.

Standard 288-pin UDIMM form factor

The stick uses the industry-standard 288-pin DDR4 layout with no heat spreader, so it fits directly into any matching desktop DIMM slot. JEDEC and RoHS compliance ensures a warranty-safe installation without BIOS conflicts. Backward compatibility with 2133MHz platforms allows use in slower systems without configuration changes.

Low-voltage operation at 1.2V

Running at the standard DDR4 voltage keeps power draw and heat output minimal inside the chassis. CL17 latency at 2400MHz delivers responsive multitasking for everyday workloads. The module is tested in-house to verify stability under normal operating temperatures.

Questions about this item

What DDR4 speed does this 2400MHz PC4-19200 module actually run at in a HP Pavilion 570?

It runs at 2400MHz CL17 at 1.2V; if the system only supports 2133MHz the module will downclock automatically to that lower speed.

Will this 288-pin UDIMM fit the HP Pavilion 570-p018na motherboard?

Yes, the 288-pin unbuffered DIMM matches the desktop DDR4 slots used in the 570-p017na, 570-p018na, 570-p018nb, 570-p019na and 570-p019nb models.

What is the correct way to seat this 4GB DDR4 stick so the system recognises it?

Align the notch with the slot key, press down firmly until both side clips click shut, then power on; the most common mistake is stopping before the clips engage fully.
