Hello,

I previously had 2 sticks of 256mb pc133 DIMM CL3 RAM in my computer.

I recently got 2 sticks of 512mb PC133 DIMM CL2 RAM.

I have 3 available slots in my computer so I put the 2 sticks of 512 in leaving a spare slot. Is it wise (will it increase performance) if I add one of my 256mb in the remaining slot or will it actually slow my computer down as it either isn't

• the same mb as the 512s
• or he same CL? as the 512s

What is the best combination for me? thanks in advance

Its not really wise to mix ram. Each brand of ram has different timings, so if you mix they default to the lowest speed. (I may not be entirely correct about that) Most people will tell you to not mix and match. If I were you, just go and get another stick of the same stuff you just bought and put it in the third slot. Man looks like you need an upgrade of a computer though. :)

I wouldn't recommend it.

lol - yeah you are right I do need an upgrade. a little short on money at this minute though. I think the motherboard is as old as I am !! Still, it does the job for me right now.


Out of interest, can you mix the quantity of RAM and get away with it if the speeds are the same?

I have mixed sizes in the past, 512s with 256s and it's been stable.

I don't see any real reason not to mix sizes, though if you mix speed then you will be running at the speed of the slowest ram, so you would be losing out, if you get me.
