    I have 2x512 sticks of DDR which run as dual channel - speed rating is PC3200. Am thinking of increasing RAM and wonder should I get a stick for the 3rd slot, which means the existing RAM will then only run as single channel, or should I replace both sticks with a 2GB dual channel kit - motherboard will support up to 4GB. Am fairly early on with my A+ so please excuse me if this is a silly question::unsure

    Depending on your motherboard it could cause instability, or you may have to swap the existing dimms to another channel.

    I recently upgraded my ddr2 RAM which I had 1GB installed I bought 2 1GB ddr dimms with a different latency I put the two new ones in the first two slots and the old one in the 4th slot as my 3rd slot doesn't accept single channels but the othe slots accept both.

    It doesn't matter if you miss out slots they should still be reconised if the dimms are correct for your mobo.

    Hope this helps

    Edit: The original RAM was a 1GB dimm on its own not 2 512s

    Best thing to do is to read the manual for your motherboard...they normally state the best configuration for RAM...however...I dont always follow them but its best to do so...it gives you an idea on what to do...so yeah best option would be to get the same sticks u already have or swap them for 1GB sticks...no scratch that...stick to 512MB sticks...the 1GB these days cost u about £30 a stick...

    Have read the motherboard manual and checked again, and hidden under a layer of dust (oops!) and a ribbon cable was a 4th RAM slot, so I can just add 2 more 512s in the unused slots as noelg24 suggested.
    Thanks guys!:thumbleft

    I would clean out the dust with a good air duster before doing anything so your new RAM has good contact with the slot.

    I once covered three slots with premium Corsair memory and it still functioned dual-channel. As stated, read the mobo manual.
