I was wondering what would happen if I took a ram stick for a desktop computer and put the wrong PC number in?

Like if you Put a 1024 MB ram stick with PC 6400 into a motherboard with PC 3200.

    It might not work. Get the correct RAM. Go with a vendor that will accept the return, and guarantee that it works! Visit

    Good luck and Happy Computing!

    In many cases it will work, but some makes and makers of memory seem to have a way of setting their memory so that the conflict will cause a blue screen... had a colleague had this happen with Kingston and Centron memory. Usually works best if you can do a best match.That way it will optimise the PC function. Unless you feel like gambling... for example some memory at 6400 requires a different voltage than a 3200, and like my friend discovered, you have to go back to exact match for a functioning PC.

    The ram that has been put in computers for the last few years is keyed, so that only the right type can go in. Also, *most* motherboards will use whatever speed you put in. For instance, if your motherboard is rated for PC2100, you can put in PC 2700, 3200 or PC4000 and the motherboard will use it as if it were PC2100. (A few cheaper motherboards dont like this and will not boot, but no harm will come to the board or the ram.)

    DDR2 is likewise keyed and you can safely use any speed that will fit.

    it would slow the 6400 down to 3200 speeds. (800mhz down to 400mhz)

    memory speeds are simply ratings. they tested the 6400 to work at 800mhz, stable, then stuck a pc6400 ddr800 sticker on it. the next batch may have had the same exact chips, but lower yields, so they tested lower at say ddr533. same sticks of ram, but one has a ddr533 sticker and one has a ddr800 sticker. so if your motherboard wants ddr400 ram, and you give it ddr800, it'll run at ddr400.

    and if you put a slow stick and a fast stick next to each other, the motherboard runs them all at the slower speed.

    however, mixing and matching different ram speeds/brands can make dual channel not work so well (ram errors, slower performance) or not work at all (motherboard reverts to single channel, or doesn't post). even non dual channel boards may not perform as well with different sticks.

    most motherboards these days have qualified vendor lists of ram that they have specifically tested to work. these have the highest chance of working. also sticking with very good brands tends to work the best, crucial, corsair, etc...

    in lots of circumstances it is going to artwork, yet some makes and makers of memory look to have a fashion of putting their memory so as that the conflict will reason a blue reveal reveal... had a colleague had this ensue with Kingston and Centron memory. in lots of cases works ideal in case you're arranged to do a ideal adventure.That way it is going to optimise the laptop function. different than you experience like enjoying... working occasion some memory at 6400 demands a different voltage than a 3200, and prefer my pal got here across, you will desire to bypass lower back to ideal adventure for a functioning laptop.
