Ohh yes, I'm having loads of problems with my KK266 review. I want to run my 800MHZ Duron at 6x133mhz, but because there is no jumpers for multiplyer, the setting 8x133 is being taken for a split second, and that is just too long... Anyone got a cheap cpu that I can run at 133mhz FSB no problems? or a great heatsink? I'm very low on cash now. Thanks for your help.
