What I was asking about is the possibility of installing more than the stated max, because apparently some have done it with no trouble (?). I don't want to put my computer at risk, but if it's possible to install more RAM without compromising the overall functionality, then it seems like a desirable thing to do. I've been running into some situations lately that point to a deficiency in that area for me. -- / dave /
