Kinda depends on your motherboard. If it only supports 100Mhz you'd end up with 512Mb. If it supports 133Mhz I'd stay where you are with the 384Mb.

hello yes you should be able to conect them all how ever the ram will only run as fast as the slowest peace of ram witch apears to be the old one at 100mhz rather than the two new ones at 133mhz. try thisee how much improvement there is. than just try the two new ones alone and decide for your self if the system is a lot faster with the 133mhz. if your system only uses 100mhz as it max tham it will be quicker with all three as they all will only run at 100mhz. have a nice day
