System-specific 2GB DDR2 module

This 2GB 240-pin DDR2 SDRAM stick is built for Asus and Asmobile P5 motherboards including the P5Q SE Plus and P5Q SE/R. It runs at 800 MHz with CL6 timing and 1.8V unbuffered non-ECC operation. The single-module kit targets owners of those legacy boards who need a direct replacement or a matched pair for dual-channel mode.

Capacity and headroom

Each module provides 2GB using a 2Rx8 organisation, and the supported platform offers four sockets with a 16GB chipset ceiling. A 64-bit operating system is required to address more than 4GB, and configurations reaching 4GB may only report 3.5GB usable due to system memory allocation. Builders planning larger arrays must populate all four slots in matched pairs to stay within the validated topology.

Build and daily implications

The stick uses major-brand chips without a heat spreader, keeping the profile low for tight CPU cooler clearances. Gold 240-pin contacts match the standard DDR2 DIMM keying, so installation is a simple press-in action with no extra cables or brackets. Because dual-channel operation demands paired modules, buyers should order two identical sticks at once to avoid single-channel bandwidth limits.

Questions about this item

Will this DDR2 800 MHz module run in dual-channel with the existing 2 GB stick I already have in my Asus P5Q SE Plus?

The motherboard has four sockets and supports up to 16 GB total. For dual-channel operation the manufacturer states modules must be ordered and installed in matched pairs.

How can I verify the module is running at the rated 800 MHz speed and CL6 timing after installation?

Open the system BIOS or a utility such as CPU‑Z; the memory tab will display the active frequency and the 6‑6‑6 timing values.

Does the package include any extra brackets, cables or thermal pads, or is it only the memory stick?

The package content lists one 240‑pin DDR2 memory module and nothing else.
