is 1.35V @4.8Ghz on a i7 4790K on water okay?
If the temps are good, then yeah.
at 100% its like 88C
A bit high for me, but anything under 90℃ should be fine for regular use, because you're probably not likely to max it out a lot.
It'll probably become unstable eventually, though.
What cooler are you using?
88°C on 100% load is a bit high.
However, how often do you realy put your cpu under 100% stress in the real world?
almost never. unless im using softwarfe mode on PCSX2 (because the graphics are better on software)
usually im only using 1 or 2 cores so yeah lol
then there is not realy much to worry about i guess. ☺
okay :) i was just worried that 1.35v in itself was dangrous
No i think its fine.
maybe you could try to lower it a bit, untill the point your system gets un-stable.
Then you know what the best voltage is for your chip at 4.8Ghz.
is it possible that some cores are better at overclocking than others? becuase it seems like core 1 and 2 can reach 5Ghz, but 3 and 4 can only reach at the most 4.9Ghz
