Where is the logic in triggering OVP in this situation? As far as I understand VT1165 principles, the sense of OVP is preventing output voltage from going beyond Vnominal + OVP (hardwired and defined with configuration resistors). Vnominal is output nominal voltage, i.e. the voltage VRM is expecting to see on output, this is the value you are seeing at RT's hardware monitoring graphs and this is the value you're programming into VRM. So for example if VRM is programmed to give 1.4V on output and resistors define OVP of 200mV, OVP condition will be triggered when real output voltage goes beyond 1.6V. This makes sense for hardware voltage mods, when you change the voltage without altering programmed VRM's nominal voltage. In this case you change voltage by altering nominal voltage yourself. And VT1165 supports much higher voltages than 1.37.
It sounds more like and OCP for me. Maximum current for each VRM phase is also hardwired with configuration resistors.
I've already posted it in other thread: you can "ask" VT1165 to report OCP/OVP conditions by reading its register 13. Bits 0 and 1 are OCP/OVP states. Take a note that these bits are read-only status bits, you cannot change them.
