You really don't want that much ram.....There is reason why buffers and ECC are mandatory on sticks above 512 and on servers. It's because, the more Ram you have, the more errors your going to get.....errors equals crashes/freezes/Crash to desktop. It has to do with solar flares from the sun, or something...I don't know.
Also....Sticks with Buffers and ECC are slower than the smaller, non-buffered sticks.
Me, personally, I not that intrested in fast computers, anymore...I'm sticking with my 1.2 Athlon, G2, Win98SE. There is just not much software that I need or want for it, anymore....I'm talking about games, of course. The only one I'm interested in is Halflife2.....and even that doesn't get me as excited as StarOcean3 Xenosaga Ep2, or MGS3.
