DDR2 667MHz kit for Asus P5 series

This 4GB kit contains two 2GB DDR2 667MHz modules built for Asus P5N-E SLI, P5N-D and P5N-T Deluxe motherboards. It suits owners of these specific boards who need a matched pair to run in dual-channel mode. The 240-pin DIMMs operate at 1.8V with CL5 timing and use major-brand chips without ECC or heat spreaders.

Matched pair enables dual-channel operation

The two sticks are sold as a kit because the target boards require modules to be ordered and installed in pairs for dual-channel mode. Using the matched set activates the board's dual-channel architecture, which the single-module alternative would not provide. No extra software or accessories are included beyond the two DIMMs themselves.

Check board model and OS before ordering

Verify that your motherboard is exactly one of the three Asus P5 models listed, as compatibility is guaranteed only for those. A 64-bit operating system is required to address more than 4GB of memory, and the system may report only 3.5GB usable when 4GB is installed depending on configuration. The board has four sockets supporting up to 8GB total.

Questions about this item

Will the 1.8V DDR2 modules need any periodic cleaning or replacement under normal use?

No scheduled maintenance is required; the unbuffered non‑ECC DIMMs have no moving parts and are designed to last the lifetime of the system.

What limits how long the kit can run at its rated 667 MHz speed without throttling?

The motherboard chipset and BIOS memory‑controller settings determine the maximum sustained frequency; the modules themselves are rated for continuous operation at 667 MHz.

How much heat and power do the two 2GB sticks add when the PC runs all day?

Each stick draws 1.8 V at standard DDR2 current levels and has no heat spreader, so total thermal output is low and easily handled by normal case airflow.
