System-specific DDR2 kit

This 4GB kit from Computer Memory Solutions contains two 2GB modules built for Intel D946GZAB, D946GZIS, D975XBX2 and DB43LD motherboards. It runs at DDR2 800 (PC2 6400) with CL6 6-6-6 timings at 1.8V. The unbuffered non-ECC DIMMs use a 240-pin layout and major-brand chips.

Upgrade path for legacy Intel boards

Owners of the listed Intel desktop boards who need to reach the 8GB maximum across four slots can use this matched pair. Builders working with any other chipset, laptop, server or later DDR generation should look elsewhere because the pin-out, voltage and timing are specific to these platforms.

240-pin DDR2 800 interface

The decisive specification is the 240-pin DDR2 800 interface; only motherboards that accept PC2 6400 unbuffered non-ECC DIMMs at 1.8V will recognise and run these modules correctly.

商品問答

What speed does the DDR2 800 interface actually run at in this kit?

The two 2 GB modules are rated for 800 MHz DDR2, which is the PC2-6400 data rate.

Will these 240-pin DIMMs fit the four slots on an Intel D946GZIS board?

Yes, each stick is a standard 240-pin unbuffered DDR2 DIMM and the board has four such sockets.

Do I need to change any BIOS settings after installing the pair, or is it plug-and-play at 1.8 V?

The kit runs at the standard 1.8 V DDR2 voltage, so most boards will detect the correct 6-6-6 timings automatically.
