Different amount of ram in motherboard slots.

[KEN]

I have 1 gb ram in one slot of my motherboard and want to upgrade to 3gb ram but i heard from some people that if i use different amount of ram in another slot then it will make the ram not work.....so i have to use 1 gb in another slot too.....is that true?

Well there's no problem at all if you want to add 2 more GB RAM on other slot - it will work :)
However, you won't be able to use the dual channel function, which is a disadvantage.
If you want to have dual channel you should have 2 equal ram modules in 2 ram slots with the same colour.
Mind that in both cases your ram modules should be the same type.

so i should use 1gb ram on second slot????
and about the colour i will paint them with same xP jk

Yes, if you want to use dual channel.
Just be sure that your motherboard supports it.

yes my motherboard supports dual channel

i have also 2 + 1 and works fine, however my friend had problems with it. older motherboards don't like this combination, but with newer ones there should be np.
note that i don't have same RAMs, they are totally different.
tried to look, but everest does not appear to show what RAM i have, it just says DDR2, but won't give specific info about RAM sticks.

i have a intel g31 motherboard and also when i scan it online it show that i have 4 ram slots but when i open my cpu there is only 2 slots available.....

i have 4 ram slots which support 8Gb in total and im using up 2 slots with 512MB in each and in the other 2 i have 2 x 2GB modules. works fine for me.
different manufacturers too. all ddr2 though

that is different case, 2 + 2 slots on motherboard are different. if you have 2 x 512mb and 2 x 2gb, then it works, but if you would swap one 512mb with 2gb, then it might not anymore.
all depending of the motherboard.

yes sethioz is right.....512mb in 1 slot and 2gb in another slot might not work but now i have 1gb in 1 slot and 2gb in another slot and its working fine for now.....
