For reasons apparent here I am attempting to underclock my AMD XP3000+... I moved the jumper that the mobo manual says should allow this, but BIOS still does not permt lower Vcore, although documentation says 1.5 should be dooable.
Now Sazar kindly explained I can monkey with my FSB to achieve this which makes sense.... I have done this and yet am not really sein gmuch change in CPU temps! ASUS probe also shows the voltage remaining at 1.68, is this right? I assume it is, but had thought maybe changing FSB caused voltage change.
Lastly I was being a bit ad-lib and did not make notes of my bios settings etc... Anyway - currently system info for my machine shows my XP3000+ as clocking 1.33 GHz - methinks I have overdone things! I would have thought at that humble clock temp would drop (measuring with folding driving CPU to 80% BTW).
What gives? And anyone care to give me suitable numbers to reset the system if underclocking is just shooting myself in the foot here.....
