HP TouchSmart 520 series upgrade

This 16 GB kit contains two 8 GB DDR3 SO-DIMM modules rated at 1333 MHz CL9. It is built for the HP TouchSmart 520-1139D, 520-1149D, 520-1175A and 520-1180A all-in-one desktops that accept unbuffered non-ECC memory.

Check your TouchSmart model and OS

Verify the exact model number on the rear label matches one of the four listed systems. The platform supports up to 16 GB on 64-bit Windows but only 4 GB on 32-bit editions, so confirm your operating system architecture before ordering.

Dual-channel kit with lifetime warranty

The matched pair enables dual-channel operation on the two 204-pin sockets. Computer Memory Solutions provides a limited lifetime warranty when purchased directly, and the modules use major-brand chips rather than generic ICs to reduce compatibility risk.

Questions about this item

Does the 16GB kit include two 8GB DDR3 SO-DIMM sticks or must I buy a second module separately?

The kit contains two 8GB sticks for a total of 16GB, so no extra module is required.

My HP TouchSmart 520-1139D supports both 1333MHz and 1600MHz DDR3 — which speed should I choose?

This kit runs at 1333MHz (PC3-10600) and is guaranteed compatible with the 520-1139D, 520-1149D, 520-1175A and 520-1180A.

Will the CL9 1333MHz rating deliver the full 16GB on a 64-bit HP TouchSmart 520 with Ivy Bridge processors?

Yes — the system supports up to 16GB on 64-bit PCs when using Ivy Bridge processors, and this 2x8GB kit matches the supported 1333MHz DDR3 specification.
