System-Specific DDR2 Kit

This 4 GB kit contains two 2 GB DDR2 DIMMs built for the Intel DG31PR motherboard. Each module is a 240-pin unbuffered non-ECC stick rated at 667 MHz with CL5 5-5-5 timings. The set targets owners of that specific board who need a straightforward capacity increase.

Thermals Noise Power

Standard 1.8 V DDR2 modules without heat spreaders run cool and silent in normal desktop workloads. Power draw stays low because the chips operate at the native DDR2 voltage and the board’s memory controller manages the two ranks without extra buffering. No active cooling is required.

Deciding Specification

The kit is validated only for the Intel DG31PR platform, which supports a maximum of 8 GB across four sockets. Builders using any other motherboard or needing ECC, registered or faster DDR2 modules cannot use this memory.

Questions about this item

How do I install the 240-pin DDR2 DIMMs in the Intel DG31PR and what step do people often miss?

Align the notch on each 240-pin module with the slot key, press down firmly until both side clips click, then verify the BIOS shows the full 4 GB at 667 MHz; the step often missed is seating both sticks fully so the clips engage.

What maintenance or replacement will the unbuffered non-ECC DDR2 kit need later?

No scheduled maintenance is required; if a module fails, replace it with another 2 GB DDR2 667 MHz CL5 1.8 V unbuffered DIMM to keep timing matched.

What limit appears first when the Intel DG31PR runs this memory under sustained load?

The board’s four-slot, 8 GB maximum capacity is reached before the memory’s own speed or voltage limits become a factor.
