Socket LGA 775 platform

This motherboard uses the Intel P45 chipset on an ATX form factor and accepts LGA 775 processors. It supports up to 16 GB of DDR2 memory across its slots. The board is intended for builders maintaining or repairing legacy systems that require this specific socket and chipset combination.

Sustained operation on older hardware

The P45 chipset and DDR2 memory subsystem deliver stable throughput for period-correct workloads such as office applications, media playback and older games. Thermal characteristics reflect the original design envelope, so long sessions remain within the limits defined by the platform. Builders should verify that their cooling solution matches the board's original specifications.

Sixteen-gigabyte DDR2 ceiling

Maximum memory capacity is capped at 16 GB, which determines whether this board can handle a given workload. Systems needing more memory than this limit will require a different platform. The ceiling is fixed by the chipset and cannot be exceeded with any DDR2 module configuration.

Questions about this item

How much power does the Intel P45 chipset draw when the board runs all day?

The Intel P45 chipset is designed for standard desktop thermal limits; pair it with a conventional ATX power supply and case airflow to keep temperatures stable during continuous operation.

Which DDR2 memory and LGA 775 processor must I already own to use this motherboard?

You need DDR2 modules up to 16 GB total and a compatible LGA 775 CPU; the board also requires an ATX power supply, at least one SATA drive and a chassis with an ATX back-panel cut-out.

Will my existing SATA hard drives and DDR2 memory work with this P45 board?

Yes — the board provides SATA ports for current drives and four DDR2 slots supporting up to 16 GB, so older SATA storage and DDR2 kits can be reused directly.
