Capacity and form factor

This A-Tech module delivers 4 GB of DDR3 memory in a 204-pin SO-DIMM package. It operates at 1333 MHz with a PC3-10600 rating and CL9 latency at the standard 1.50 V. The stick is unbuffered and non-ECC, making it a direct drop-in upgrade for compatible laptops and all-in-one systems.

Compatibility and exclusions

The part replaces HP part numbers including AT913AA, AT913UT, 536726-652, 575480-001, 621569-001, 577606-001, AT913ET and VH641AA. It suits owners of those HP models who need a single 4 GB upgrade. Builders requiring higher capacity, ECC error correction, registered modules or a different DDR generation should look elsewhere.

Deciding specification

The 1.50 V operating voltage is the single figure that determines whether this module will work in a given system. Only platforms specified for standard-voltage DDR3 at 1.50 V can use this memory reliably.

Questions about this item

Does the 4 GB DDR3 SODIMM arrive as a single stick or a kit, and is anything else required?

It ships as one 4 GB module; no extra parts are needed for installation in a compatible laptop.

Should I pick this 1333 MHz CL9 module or a faster DDR3 SODIMM for my HP laptop?

Choose this 1333 MHz CL9 part if your system specifies PC3-10600; a faster DDR3 SODIMM will simply down-clock to 1333 MHz.

What does the 1333 MHz rating mean once the stick is installed in my machine?

The module operates at 1333 MT/s with CL9 timing at the standard 1.5 V DDR3 voltage.
