This is interesting, my motherboard (Intel DP965LT) seems to suffer from the same problem: putting 4GB of memory in it makes it dog slow, while putting 2GB in it makes it lightning fast... I've just given up trying to put 4GB of memory in this machine, but I believe this may help... Please, keep me posted if the BIOS update fixes it for you. Regards, -- Rink P.W.
