Targeted System Upgrade

This 2GB DDR2 module is built specifically for the ASUS/ASmobile M2N32-SLI Deluxe motherboard. It addresses owners of that platform who need a straightforward capacity increase without compatibility guesswork. The stick delivers 2GB of non-ECC memory in a single DIMM.

Build Integration

The DIMM uses a standard 240-pin DDR2 interface and runs at 1.8V, matching the electrical requirements of the target board. It occupies one of four available memory sockets and leaves the remaining slots free for further expansion up to the board's 8GB maximum. Unbuffered operation keeps the signal path simple.

Sustained Operation

Rated at 667MHz with CL5 5-5-5 timings, the module maintains its specified latency and bandwidth during extended workloads. Major-brand chips provide consistent stability without a heat spreader. The 2Rx8 organisation supports steady throughput for typical desktop tasks on this legacy platform.

Questions about this item

Will the 667 MHz DDR2 speed hold steady during long render jobs?

The module runs at 667 MHz with CL5 timing at 1.8 V, and the unbuffered non-ECC design keeps latency consistent under sustained load.

How much heat does the 1.8 V DDR2 stick produce when the system runs all day?

Operating at 1.8 V without a heat spreader, the 240-pin DIMM stays within standard DDR2 thermal limits for continuous operation.

Does my ASUS M2N32-SLI Deluxe need a BIOS update before installing this 2 GB DDR2 DIMM?

The stick is validated for the M2N32-SLI Deluxe and M2N4-SLI; the board supports up to 8 GB across four sockets with no extra hardware required.
