I bought a few brand new T-bird Slot-A's in the hope of upgrading mine and my fathers PC and now plans have changed. I upgraded mine but he is not keen on upgrading. The CPU is great and overclocks well. I ran 112 mhz Front Side Bus to obtain 950 mhz. I only used in my Asus K7M for a month with 106 mhz FSB though Here are the motherboards it works with. Asus K7M and K7V-t NOTE:"Asus K7V-t. That "-t" is very important. Check AMD website for full motherboard compatibility as listed here:" FIC SD-11 Freetech P7F200 Gigabyte GA-7IXE Microstar MS-6195 Shuttle AI61 Soyo K7AIA $60.00 USD plus shipping. This is a good upgrade if you have a slower Slot-A and want more speed by simply swapping the CPU. Comes with dual-fan CPU cooler (sounds cheesy but it works as good or better than my Golden Orb for Slot-A). With golden fingers you might be able to overclock more.
