HP Pavilion 570 DDR4 upgrade

This 4 GB DDR4 2400 MHz UDIMM is built for HP Pavilion 570-p044nz, 570-p045ng, 570-p045xt, 570-p049 and 570-p049ng desktops. It targets owners of those systems who need a modest capacity boost for everyday multitasking. The module follows JEDEC specifications for a warranty-safe upgrade path.

Tool-free DIMM installation

The 288-pin unbuffered stick slots into the motherboard without extra tools or cables. Align the notch, press until the retention clips click, and the system recognises the memory on next boot. The only common issue is leaving a slot partially seated, which causes a no-post condition.

4 GB single-rank headroom

CL17 timing at 1.2 V handles web browsing, office suites and light media playback comfortably. Capacity runs out when multiple large applications or virtual machines are open simultaneously, forcing the OS to swap to slower storage. Backward compatibility with 2133 MHz platforms is supported.
