sori i guess i was tryin 2 say few things at once:-
1)is my voltages quite high for 3.82ghz on i3 530?
2)wat is pch and cpu pll voltage?
3)my rams are 1333mhz on stock, now running at 1730mhz how far more can i push it?
Wasn't able to find what your voltages are, so I can't answer #1. Number 2, I leave stock. I don't quite understand them, so I leave them alone (but manually enter in stock values). Number 3, they will go as far as your IMC is willing to allow them.
I've had 1333 ram running 981mhz/stick (1962mhz) on some-what high dram voltage.
