System-specific DDR2 upgrade kit

This 4 GB kit contains two 2 GB unbuffered DDR2-800 modules built to the PC2-6400 standard with CL6 timings and 1.8 V operation. The 240-pin DIMMs use major-brand chips in a 2Rx8 configuration and are validated for Intel DG33FB, DG33TL, DG35EC and DG45ID motherboards. No heat spreaders are fitted.

Suited for legacy Intel desktop repairs

The kit matches the exact density, voltage and timing required by the four listed Intel boards, making it a direct drop-in for restoring or maxing out those systems. Builders working on platforms that need registered or ECC memory, or boards that only accept a different DDR generation, should select another part.

240-pin DDR2 form factor decides fit

Only motherboards with DDR2 240-pin slots that support PC2-6400 at 1.8 V can use these modules; the physical keying and signalling prevent installation in any other memory generation.

Questions about this item

Will this 240-pin DDR2 kit work in a board that currently uses 240-pin DDR2 modules?

Yes, the kit uses the same 240-pin DDR2 form factor, so it fits the same slots as your existing DDR2 memory.

Can I add this 4 GB kit to the Intel DG33FB alongside the original memory?

The DG33FB has four slots and supports up to 8 GB total, so adding this 4 GB kit leaves room for the original modules if they are also DDR2 800.

How can I confirm the system sees the full 4 GB at 800 MHz after install?

Enter the BIOS or use a tool like CPU-Z; it should show 4 GB total and a DRAM frequency of 400 MHz (DDR2 800).
