1. dik za info našel sem od Eagla:
Na A64 se do pamětí nesmí dávat 2.8V nebo víc, protože pak už je značné riziko zničení řadiče, čili i procesoru (viz. fórum XtremeSystems). 2.8V je podle datasheetu procesoru absolutní maximum pro paměti.

a na foru XtremeSystems:
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 ?

takze 2,8V je ok
