4GB DDR3 1066MHz SODIMM for HP Laptops

This 4GB DDR3 module runs at 1066MHz with a PC3-8500 rating and fits 204-pin SO-DIMM slots. It is built as a direct replacement for HP part numbers 577780-001, 581097-001 and 510402-001. The stick is unbuffered, non-ECC and operates at the standard 1.50V. It targets owners of compatible HP laptops, notebooks or all-in-one systems who need a straightforward memory upgrade.

Single 4GB module with CL3 latency

The kit provides one 4GB rank organised as 2Rx8, delivering a modest capacity increase for everyday multitasking and faster application loading. At DDR3 1066 speed the module handles typical office workloads and web browsing comfortably. It will not satisfy heavier workloads such as video editing, virtualisation or modern gaming that demand larger memory pools and higher bandwidth.

Drops into 204-pin DDR3 slots without extra power

Installation requires a free 204-pin DDR3 SO-DIMM socket and a system that accepts 1.50V unbuffered non-ECC memory. No heat spreader is fitted, so the module stays low-profile for tight chassis clearance. The upgrade frees a second slot for future expansion if the platform supports more than one module. Buyers whose systems need ECC, registered DIMMs or a different DDR generation cannot use this part.

商品問答

Will this DDR3 1066MHz CL3 SODIMM run alongside my existing DDR3 1066MHz memory?

This module operates at DDR3 1066MHz with CL3 latency and 1.50V. For stable dual-channel operation, match the speed, latency and voltage of your current modules; the system will run at the slowest common settings.

How can I confirm the 4GB DDR3 1066MHz module is detected at the correct speed after installation?

Boot the laptop and open the BIOS or a system-information tool such as CPU-Z. The memory should report 4GB capacity, DDR3 type, 1066MHz frequency and CL3 timings.

Does the single 4GB 204-pin SODIMM come with any installation tools or extra cables?

The box contains only the 4GB DDR3 1066MHz 204-pin SODIMM module. No tools, cables or additional hardware are included; installation requires only a compatible laptop slot and a small screwdriver.
