OWC 4GB DDR4 2400MHz UDIMM for HP Pavilion 570

This 4GB DDR4 2400MHz CL17 module is built for HP Pavilion 570-p019nl, 570-p020, 570-p020ns, 570-p021nc and 570-p021nf desktops. It installs as a standard 288-pin UDIMM and runs at 1.2V without ECC or buffering. The stick is JEDEC compliant and backward compatible with 2133MHz systems.

Who this suits and who should look elsewhere

Owners of the listed Pavilion 570 models who want a simple, warranty-safe capacity boost will find this module a direct fit. Builders needing ECC error correction, registered buffering, higher frequencies, larger single-stick capacities or support for platforms outside the named HP models should look elsewhere.

Deciding specification: 4GB capacity per module

The single figure that determines fit is the 4GB density per 288-pin UDIMM. Verify your motherboard accepts this capacity per slot and that the total installed memory stays within the system limit before purchasing.

Questions about this item

Does this 288-pin DDR4 UDIMM fit the HP Pavilion 570-p020 desktop?

Yes, the module is listed as compatible with the HP Pavilion 570-p020 and the other four Pavilion 570 models in the compatibility list.

What is the common mistake when installing this unbuffered DIMM in a Pavilion 570?

Not pressing the module down until both side clips snap shut; a partially seated stick will cause a no-post condition.

Will this 1.2V CL17 stick need a firmware update or paired module later?

No firmware is required; it runs at 2400 MHz or downshifts to 2133 MHz automatically, and can be used alone or added to existing memory.
