8GB DDR3 upgrade for HP Pavilion P2

This 8GB DDR3 1333MHz module is built specifically for HP Pavilion Desktop models P2-1105, P2-1107 and P2-1155il. It uses a 240-pin DIMM form factor with CL9 timing and runs at 1.5V. The unbuffered, non-ECC design suits standard desktop workloads and the single 8GB stick adds capacity to compatible systems.

Passive operation with standard voltage

The module has no heat spreader and draws power at the standard DDR3 1.5V level. Without active cooling or extra voltage headroom, it runs silently and generates minimal heat inside the chassis. Power draw stays within the JEDEC specification for DDR3 10600, so the existing system cooling handles normal use without adjustment.

Single-stick kit for paired installation

The package contains one 8GB stick based on a major-brand chipset. The system board provides two sockets and supports up to 32GB total, but dual-channel mode requires modules to be ordered and installed in pairs. A 64-bit operating system is needed to address the full capacity. If 4GB is already installed, the recognised memory may be reduced to 3.5GB or less depending on configuration.
