Computer Memory Solutions 4GB DDR3 1600MHz CL11 1.5V DIMM memory upgrade

System-specific DDR3 upgrade for HP Slimline

This 4 GB DDR3-1600 module is built for HP Pavilion Slimline 400-314, 450-134d and 450-a10na desktops. It runs at 1.5 V with CL11 timing and uses a single 240-pin unbuffered DIMM. The kit contains one stick and is sold new with a limited lifetime warranty from the manufacturer.

Drop-in installation with standard DIMM slots

The memory fits directly into the two DDR3 slots on the supported Slimline boards; no tools beyond opening the chassis are required. Because the systems accept a maximum of 16 GB across two sockets, adding this 4 GB stick works best when the second slot is empty or already matched. Mismatched capacities or mixing ECC and non-ECC modules will prevent boot.

Ideal for restoring or modestly expanding Slimline

Owners of the listed Pavilion models who need a replacement stick or a simple capacity increase will find guaranteed compatibility. Builders targeting higher capacities, faster speeds, ECC support or a different form factor should look elsewhere, as this module is locked to DDR3-1600 non-ECC and the named chassis.
