Socket LGA 775 DDR2 platform

This ASUS P5QL PRO motherboard uses the Intel P43 chipset and accepts LGA 775 processors with up to 16 GB of DDR2 memory. It suits builders maintaining or repairing legacy ATX systems that still rely on this socket and memory standard.

Thermals noise and power

The board draws power typical for a P43-based ATX design and runs with standard air cooling in a ventilated case. No liquid loops or specialised heatsinks are required for normal operation at stock speeds.

Upgrade context

It replaces a failed or missing LGA 775 board in an existing chassis and restores SATA connectivity with the included cable. The jump is worth it only when the current board is dead or lacks the 16 GB ceiling this model provides.

Questions about this item

How is the LGA 775 socket installed and what step do people get wrong?

Align the processor notches with the socket keys, lower the load plate, and lock the lever; the step often missed is removing the protective cover before seating the CPU.

What maintenance or replacement will the board need later?

The metal battery on the board will eventually lose charge and should be replaced to keep BIOS settings and system time.

What limit shows up first under sustained use on this P43 board?

The DDR2 memory ceiling of 16 GB is reached before the chipset hits thermal or bandwidth limits during heavy workloads.
