4GB DDR3 SODIMM for HP TouchSmart 520

This 4GB DDR3 module is built for the HP TouchSmart 520 series. It runs at 1333MHz with CL9 latency and 1.5V operation. The 204-pin SODIMM fits the factory memory slot in these all-in-one systems.

Suitable for restoring or expanding original memory

Owners of a TouchSmart 520 using DDR3 can install this single stick to replace a failed module or add capacity. Systems that require ECC, registered DIMMs, or a different DDR generation cannot use this memory.

Handles everyday multitasking and larger files

The 4GB capacity lets you open more applications and work with bigger documents simultaneously. Workloads that need more than 4GB of total system memory will run out of headroom on this module alone.

Questions about this item

Does my HP TouchSmart 520 need a free 204-pin DDR3 SODIMM slot to install this 4GB module?

Yes, the module is a 204-pin DDR3 SODIMM, so an available DDR3 SODIMM slot in the TouchSmart 520 is required.

Will this PC3-10600 CL9 1.5V stick run with the original DDR3 memory already in my TouchSmart 520?

It is designed to meet OEM specs for the TouchSmart 520 series, so it should operate alongside the factory DDR3 at the system's supported speed.

How can I confirm the 4GB DDR3 1333 module is recognised correctly after fitting it?

Check the system BIOS or Windows Task Manager — both should show the additional 4GB running at 1333 MHz with CL9 timings.
