I have an old (but very stable) A7V8X-X system that I use for Photoshop CS. I want to add more memory. I would like to add three 1 gb (modules) of pc2100 266 (matched or at least the same). The manual says this is the max amount of pc2100 266 that can be used. My question: is it stable to max out the memory with this board? I seem to remember reading a thread (many, many years ago that maxing out the memory on a board 'may' cause stability problems. Yes, I searched and did not find the answer(s). The Asus.com site appears to be 'under construction'.
