Ok...so my question before about whether a 1.2ghz Tbird running at 266fsb would run on my KT7-Raid without the KT133a chipset might not have been specific enough. After ordering the CPU I realized "it might work, but what is the 1.2 gonna run at?". So my question to you is: am I going to be screwing myself and having a 1.2ghz Tbird that is underclocked to 900mhz because my board can't support the full 133mhz FSB? I should have made the question more clear before...so it's my own fault if not. Might just have to upgrade my moboard after all? Final draft form of this question: "With the KT133 chipset will a 1.2ghz 266FSB Tbird run at it's clocked speed of 1.2ghz? or is it going to be stuck at 900mhz unless the multiplier is unlocked?" Thanks
