I have a throughbred athlon xp 1800. As you know, it is default at 1.53Ghz and 133 fsb. Right now, i have it at 1.66 Ghz and 166 fsb. I dont know if this is a tbred A or B, but i here some of you guys getting 2300 mhz out of 2100s easy, my question is, Im using stock cooling, what do you think my chances are of reaching 2 Ghz on my 1800, remeber its a tbred, and seems to be running really well at 1.66 ghz.
