I tried the 109 bios, but its not possible to adjust the voltage anymore. I think it stays with 1,75 and 1,80 volt, as long as you dont load setup default, else it just vanishes. Other bios from 107 on are displaying voltage
adjustment, altough the Probe programm report ALWAYS 1.5 V.
So it might be much more in this new prozessor, with an old
bios.
Please let me know, if you find a real old version.
