wow, tak skal du have, det er sq rart at vide *thumbs up* ;)

Wow.. Jo-Tak!
Havde faktisk tænk på den teori før, og havde alligevel en ide at lege med noget BH-5 Her om et par dage..
Så Takker for info.. :D

det var ham den rare gut fra madshrimps (ham der sælger cpu'er) der sendte linket med i en email ang. han ville sende min cpu, så opgav han lidt info om max vcore på den og så det link der, tænkte nok det kunne bruges :i

Det er god læsning, især dette:
First of all, the CPU doesn't have to do directly with the VDD, but with Vtt/Vref, wich should vary from 1.25 to 2V when you adjust the RAM from 2.5 to 4V. Maximum JEDEC Vdd voltage is 2.85V, and lowest voltage for A64 CPU's (CnQ activated) is 1.1V, so we know for sure that a difference of 0.325V between Vcore and Vtt is safe. This means that for a 1.35V Vcore voltage, we can have a safe Vdd of at least 3.35V, and for 1.5V Vcore -> 3.65V Vdd.
Probably the real danger is when those diodes go near the opening (conduction) voltage, wich should be ~0.6V for Si-based junction; if this is true, 1.35V Vcore and above 3.9V Vdd should kill the CPU instantly ... anyone wanna try ?
