ok, From reading different reviews, specs, and forum conversations i've made the assumption that this will work. can you guys tell me if it wont.. thanks ok what im going to try to setup is.... a intel celeron 2.6ghz @400mhz on (any motherboard with 800mhz fsb) with 1 stick of 256mb 266mhz ddr ram and 1 stick 512mb 333mhz ddr ram with windows xp, nt or 98se now the motherboard that im planning to use says it works with 400mhz ram will it also work with the 266 and 333mhz ram and just downclock to 266 and also the motherboard is suposed to automatically downclock to 400mhz and match the cpu right? so if it works the system will run at 400mhz fsb, and the memory will run at 266....right?? will this work??
