i7 4790k max safe cache/vccsa voltages and others doubts

[ppdemo]

hi guys, like questions say , first, i need know max safe voltage for this options items:

cpu cache voltage
cpu system agent voltage(analog and digital I/O) is this the IMC?

i have a z97a mother, and i want to know what means vttddr option, I am confused if this is the IMC or VCCSA is?

nobody??

1.25v for skylake / kabylake - not sure that helps though.

1.25 cache or VCCsa?

VCCSA

VTTDDR has to do with the ram of course, it usually seems to be about 1/2 of the DRAM voltage.

other question, how can i see/monitor cpu analog and digital I/O Voltages? my motherboard dont show me these, only offset. What I can see is Vccsa voltage.

guys, what is max safe recomendation vccio for i7 4790k 24/7 use?

looking around the net, it looks like 1.2V seems to be the max, so a little below that.

thanks. now i need found the correspondence of hwinfo V1 voltage, I already did everything to find out which voltage corresponds, i have increased and lowered voltages of all items in the bios to see, maybe, if there was something similar but nothing, maybe a bad reading of hwinfo64, My concern is that at idle this v1 voltage is maintained at 0.981v average but to full load this raise at 1.5v!!!

thanks all, finally i have found 2 stable OC settings
1- 4.7ghz 1.272vcore 40x cache
2- 4.8ghz 1.312vcore 40xcache
maybe the second is too much and the cpu will degrade faster...i dont know if i use it.
Anyway I use IXTU to change profiles
