I have a DDR2 1 GB RAM installed into my system and it's bandwidth is 266 MHz now I am planning to insert another 1 GB RAM with a different bandwidth this RAM has 400 MHz. So can I have 2 RAM's of different bandwidth? But their size is same i.e 1 GB.

My motherboard supports upto 4GB DDR2 RAM of 600 to 800 MHz.

Is the other stick DDR2 as well?

 

If so, this probably will work (unless they have different timings) but both sticks will operate at the lower speed (the 266 MHz) since they are different speeds.

 

I would strongly recommend getting a stick from the same manufacturer and model if you are adding another stick.

@gigawert
The new one which I am trying to install is also DDR2 but it is 400MHz.

Also tell me whether the bandwidth makes a lot of difference. Isn't it only the size which has to make the difference? Or is it both?

Also note the manufacturer of my old RAM is no more available.

Since those sticks are pretty cheap you could probably get 2 sticks of 2 GB DDR2 that are 800 MHz. Yes, it is both.

No sorry I can't afford for 2GB. But I can afford for 1GB only.

So please tell me whether both the RAMs will work together and if yes then will they increase my speed at least by 50%.Currently I don't have any speed problem with my Windows 7 ultimate it's only when I do my Windows update I do encounter speed problems.

You may run into compatibility problems IF the two sticks do not have the same timings. May want to take it out and see if the timing matches with the new one.
