hi i have some news for the z390 aorus ultra. got it cheap for 200€/~225$.
first the good stuff, the vrm section has great thermal properties.
i7 8700k @ 5ghz 1.4V(yeah , lucky me...) prime 29.4 and the vrms get barely warm.
i first thought the vrm sensor was broken, but manual measurements came to this:
1h prime 95 small fft vrm sensor 47°C and a sensor on the back with 35°C(@19°C ambient)
with prime 26.6 it is even colder, like 38°C vrm sensor.
so great work
, i came from a prime z370 a which just shut off because vrm overheating.
now the bad stuff,( all [email protected]
the llc is a joke versus the old asus prime a, the prime a could rock non avx load 5ghz @ 1.325V with llc level 6(so like 1.33 idle and 1.325 under load)
but the prime is a trash board so i was quite impressed.
the aorus ultra was unstable with this settings, and even 1.4V isn´t 100% stable, so i fired up hwinfo, and holy..
@1.325V with llc extreme(!) it fluctuates from 1.296-1.368V
@1.4V the range is 1.375-1.464V
i think it´s nuts, like, ***? and i am not talking about vid of cause.
i don´t know if gb has a different sensor readout setup, but for me this explains the really bad voltage scaling.
another thing: on german/english and both chinese bios languages are no settings for vrm switching frequency or duty mode(like, how much are on and are some disabled for better efficency, sometimes you want to disable such things).
i think they are important, because the asus prime a could run much better in full phase mode, like 200mhz better.
with that knowledge you cannot recommend this board to anyone, exept someone who just wants a cool board for his ultra silent watercooling setup, as the board cools itself so damn good.
but anything oc related it is just carried by it´s vrm section to a certain degree and then the bios just says: nope!
great thanks to all in this thread it is a great read, thx(or not?
) to GBT-MatthewH and buildzoid for convincing me to buy the gb board, technically it is real top.
special thanks to alphaC, i like graphs and equations
: i dont care if i take 5minutes to find something just because i am used to asus, but, i care about missing features and even more do i care about stuff not working(llc? ***?).
do you know of a fix coming anytime soon?
it would be good to put an audio driver up with an actual GUI too, i mean i have a asus xonar d2x so i´m fine, but still no quality support feeling to have to install the driver+gui from an z370board just because there is everything available.
