Max 4790k cache voltage?

[UltraNeonGaming]

I am over clocking ATM, currently I'm playing with voltages, CPU voltage is set to offset (-) with offset being 0.048 volts this results in a total voltage of 1.2volts or 1.219 depending on how intense the stress test is.

I have also changed the CPU cache to a max of 45 (Same as CPU multiplier).

I am wondering if I should mess with my cache voltages, or leave them on auto? My cache voltage is at 1.293V in the BIOS, this looks pretty high too me, what should I do?

Thanks!

they generally dont need to be that high for a stable overclock as long as temps are fine you wont have any issues just try and bring the voltages down when you get the desired overclock.

What should my cache voltage be? My core voltage seems good, I am only worried about cache voltage

enough that it does not cause stability issues.

What should the max be?
