OK i have a Sempron 64 2600+ which it 1.6Ghz stock on an ASUS K8U-X. before i did anything but changing bios options i could get it to 2.24 Ghz perfectly stable. Now here comes my problem, when i went any higher it would say voltage selected was too low so i didn't even try any higher because the Sempron doesn't support cool'n'quiet so i can't change the voltage in the bios. So i found a link to a pin mod for 754 CPU's and i got the vcore up to 1.45 V from 1.4 V but it only got me an extra 50 Mhz, once i get past 2.27 Ghz it won't post. I have tried to loosen the timings on my ram and limit the mem clock to the lowest possibility (100 Mhz which ends up bieng more), limiting the AGP to 4x instead of 8x, and turning down the HT to a 1:1 ratio. Nothing changes it so my question is: what is my bottle neck? my ram which was only $20 so that might be it, my Chipset? which is an ALI ULI M1563, or is it my 350 watt power supply? I can't figure out what i need to get next but i have seen people get this same processor with the same stepping much higher than what i'm getting so i would like to know.
