Okay. So i am planning it to combine this with a 2gb stick @667mhz. So would it work? Do i Though the clock speed and voltage are the same, it's best if the memory are also the same. Two different sticks will not always work together. Most of the time they will, but it's kinda risky since sometimes, it *DOESN'T*.
Well, it is up to you to take the risk or nah. Or just get the exact same stick you have and it should work, as long as the seller sells you the RAM in good condition.
