So, avoided in the case that you want to be running everything at its best, then yes. Avoided to prevent permanent damage, not necessarily. You might check the docs for your specific motherboard to see the max amount of RAM it can use (and max speed rating), in many cases for desktop boards with 64bit CPU, it is 8GB or 16GB. Server rated boards can get into some big numbers such as 128GB etc. In any case it would make sense to get rid of the older slower sticks and put in newer faster higher capacity sticks. Something to look for, if/when shopping for new RAM, there seems to be a good deal of savings when buying them in pairs, such as 2 x 1GB sticks, or 2 x 2GB sticks etc. At least I usually see this on places I shop such as Newegg.com. I just bought a pair of 2GB sticks which will be going in to my wife's computer. > > And let's face it more RAM is always a nice thing to have ;). > > Indeed.
