Tenchusatsu (edited)- here's the post Message 17813182
Also read the responses.

and here's the link linear.com

and the key sentences:

The LTC3719’s 5-bit VID code corresponds to the core voltage range of AMD’s Hammer CPUs. Core voltage range is from 0.8V to 1.55V and core current can range from 15A to 40A.

From that, its hard to believe that the spec Vcc is more than 1.4 volts. They have to allow a little room for the overclockers. Although the chips max rating is 45 amps, 40A appears to be the max for any Hammer chips they know about.

I would guess code 0=0.8v
32 steps of 0.025v would give a max voltage of 0.8+31*.025= 1.575 volts.

Re: 40 amps at 1.5V seems rather miserly. Maybe it's the SOI

The light begins to dawn.

What have I been saying for a year, now?
