    Will memory run at the fastest supported speed?

    I am going to upgrade the ram in my friends pc which uses DDR1. His motherboard supports max speed of pc2100. However, pc2100 is more expensive than pc2700 memory.

    Can I use a pc2700 memory and it will work but at the slower speed of pc2100?

    Thanks

    Re: Will memory run at the fastest supported speed?

    Thanks for the quick reply. I knew ddr2 memory could run at slower than the rated speeds, but just wasnt sure about ddr1

    Could anybody else please just confirm again that it should work so that I can be sure before I buy it?

    Thanks

    Re: Will memory run at the fastest supported speed?

    The computer I'm using right now has PC3200 (DDR400) running at PC2700 (DDR 333) speeds, because that's the fastest the processor supports. The motherboard supports PC3200, so I actually had to manually select PC2700 in the BIOS, but other than that, it is the same situation as yours.

    You might have probelms, not from underclocking it but from type+motherboard.
    (refureing to high density/low density memory here)

    Yeah, good point.

    What's the motherboard? You should be able to look all this stuff up on the manufacturer's website if you want to be really certain.
