VRIN setting in XTU

[cold0904]

Hello

I'm in the process of undervolting my CPU (and have successfully done so, my i5-4460 is now 0.95 volts instead of the initial 1.03 volt at load).

I was told that VRIN (Cpu input voltage) should be ideally 0.4-0.6 volt higher than the V-Core, and anything higher than 0.6 volt is not good for the long-term durability (stress on the component).

However unlike other settings, i cannot find VRIN adjustment inside XTU. Does anyone know where it can be found ? In my bios of my MB (Gigabyte H97N), i cannot adjust my VRIN lower than 1.7volt, so thats why i was looking for XTU

Also, is there a tool that displays my VRIN in windows ? None of my utilty (CPUZ,HWmonitor,COretemp), seems to be displaying the VRIN....

Thx

I don't think that will hold true, as stock VRIN is about 1.8V. So, even at stock no undervolting, your at nearly .8V difference.

I totally agree with you, normal PC will have a 1 - 1.8V gap. Then, i don't understand why people say that 0.5 V gap is the optimal gap... i understood that unnecessary higher gap adds nothing to stability, but only to temp and lifespan.

Very interestingly, at stock (before undervolting), i cannot manually set my voltage at 1.7V, even if my stock voltage is at 1.02V.

Maybe some kind of minimum margin requirement for voltage. By lowering to .95, 1.7 became available. Could be that .8 is the minimum allowed.
