i2500K OC with auto-voltage

[Heligrin]

Im curious how efficient/effective it is to use "auto" vcore voltage when OCing an i2500K? I left everything at default and upped the multiplier to 45. I prefer auto because of the benefits of low vcore while idling.

Vcore whilst running prime95 = 1.28 volts (When i was at 4.3 with auto (1.24 volts) i was perfectly stable)
Max temps ~63C

Is using "auto" reliable for ocing? Is it always stable? (Passed IBT and 2 hrs prime (need to go longer))

Thoughts?

No it feeds it too much voltage on auto. Best to use "offset" mode and then set a negative value in offset. You get all the benefits of "auto" including the low idle vcore and it wont overvolt the chip.

Say for example auto gives it 1.5v at 4.5ghz 100% load, thats too much. Using offset and setting offset to say -0.2v will give a voltage of 1.3v at 4.5ghz 100% load which is much better, you can adjust the offset to your liking to get it stable, offset can also be a positive value if needed.

If those voltages are true then I see no issue with you running it on auto.

What are you using to monitor your voltages?

Depending on your MB choice you sometimes have the option of offset voltages which let your chip throttle voltage/speed at idle.
