System-Specific DDR4 Upgrade

This OWC module delivers 8 GB of DDR4 2400 memory tested for HP Pavilion 570-p597ng 570-p750ng 570-p751ng and 570-p755ng desktops. It runs at 1.2 V with CL17 latency and meets JEDEC PC4-19200 specifications. The unbuffered non-ECC design fits standard 288-pin desktop slots.

Build Integration

The stick installs directly into an available UDIMM slot on the supported Pavilion motherboards without requiring ECC or registered memory support. Backward compatibility with 2133 MHz systems lets it work if the platform defaults to a lower speed. No heat spreader means clearance is minimal for tight chassis layouts.

Upgrade Context

Replacing a 4 GB or 8 GB DDR4 2133 module with this 2400 MHz kit raises bandwidth for multitasking and larger workloads. The jump is worth it when the board supports 2400 natively and the user needs more capacity than the factory configuration provides. Buyers needing ECC error correction or registered DIMMs should look elsewhere.

Questions about this item

Will the CL17 latency hold steady when the module runs at 2400MHz for hours?

The module is rated at CL17 for DDR4 2400 operation and meets JEDEC specifications, so latency remains consistent under sustained load.

How much heat or noise does the 1.2V unbuffered DIMM add during all-day use?

Without a heat spreader and at 1.2V, the stick runs cool and silent, adding no audible noise or noticeable warmth to the chassis.

My HP Pavilion 570-p750ng has empty DDR4 slots — is anything else required to install this 8GB UDIMM?

The system must support 288-pin DDR4 UDIMMs and have a free slot; the module itself needs no extra cables, brackets or software.
