I orderd and received a new Athlon 1.2Ghz (266Mhz) from NewEgg. I also got the ECS K7VZA (KT133A) mobo. After hooking it all up the damn thing only comes up at 900Mhz. The chip marking clearly state it's a 1200. After flashing the mobo it still did it. It seems like the mobo/chip is detecting it's FSB at 100Mhz (200) instead of 133Mhz (266) with the multiplier at 9x. This mobo doesn't let you select the FSB, instead it lets you tweek it up a bit but since it's 100Mhz it only lets me tweak it up to 113Mhz, still getting me nowhere near the 1.2Ghz I wanted. I then stuck the CPU in a different mobo and sure 'nough it came up at 900Mhz too. Is my Athlon improperly marked or it's FSB inproperly set at 200 instead of 266? Am I missing something?
