mixing DDR ram, ok or no?

Do you guys think I will have trouble mixing a 1GB DDR 400 {Corsair}, with a 512 Crucial, or a 512 nanya.

Computer currently has both those 512s in it, I want to take one out and add the 1gig stick to make 1.5gb ram...

Thanks

It will not hurt it, but you cannot run in dual channel mode, and if stick A and stick B have compatibility issues between them, it won't work at all. However, it should not harm your system granted you take all the safety precautions of installing RAM. Like proper grounding and ESD safety and such.

If they are different speeds and they do work together you will run at the lowest speed regardless.
 
well I did figure it would not hurt the computer. I was trying to ask if there was a way to tell if I would have compatibility issues. and if so what are my chances. Because I am buying the 1gig stick...

Try it and find out, it is pretty obvious if you have issues. You will get memory dumps, blue screens, boot issues, etc. It may not even POST if it is 100% incompatible, but the only way to know is to try it.

While, the chances of having data loss occur may be slim, always back up data that is crucial before doing such things.
 
As long as the timings match it should be okay. Bear in mind if a few sticks are DDR400 and one stick is DDR333, they will all run at DDR333 by default
 
voltage, could be an issue too. You want to make sure they match otherwise (or are very close) because it creates issues at times.

Example: mix gaming ram with value ram etc.
