Okay, so I'm trying to have my cake and eat it too. I want to build my first box and I thought that the ka266 supported both sdr and ddr mem. Sooooooo, I was going to get a 850 t-bird and cheap pc133 mem, use it for a year and then upgrade to a 266 fsb cpu and ddr mem. I just read a review of the board in overclockers mobo reviews and it said the mb only supports ddr???? Does anyone know, I thought the Ali Majik1 chipset supported both sdr and ddr but I'm a newbie and probly got it screwed up. Thanks,
