this motherboard here is the z4 90 horas
Pro ax now I think this is the best z4
90 motherboard coming out of gigabyte
norris's whole lineup in the z4 90 stack
and I've also tested the Auris master
here as well as the gigabyte vision G
and this one here the reason why I'm
going to be picking it out of the other
two motherboards against those is that
it's the better value option I feel that
it's loaded with features and it does a
really good job of overclocking where
it's coming in at a price point of 270
US dollars but then also in Australia
it's coming in at 477 AUD so if you want
I believe what is a top-tier board and
handles of 5.2 gigahertz ten 900k
overclock with doing so with pretty good
efficiency levels then this would be the
board to consider and the first reason
for this is that they're using a 13
phase that's twelve plus one phase where
twelve phases are dedicated towards the
CPU and this is direct drive MOSFETs now
when we tested out the ten 900k at 5.2
gigahertz this was scoring 264 watts
which was actually coming close to that
of the Z 494 Lawson 2 which I tested
here on the channel as well as the MSI
Zi 490 Meg ace and we've got a Z 490
comparison coming up we're going to
round up all these boards in a video but
these are some pretty good numbers as
well as the temperatures themselves
where we saw a maximum surface
temperature of 85 degrees and then on
the vrm readout in the software we saw
85 degrees as well and 63 degrees on the
heatsink surface temperatures of course
out of the box if you just want to run
it at 4.9 gigahertz all cores on 10
cause this will juice it to around 197
watts anything over these levels you do
start to lose a lot of efficiency with
the ten nine hundred K but this board
definitely makes up for a little bit of
that using a very quality good vrm
solution you've also got tantalum caps
on board which is something that I do
really like however with the heatsink
design it weighs in at roughly 175 grams
so it is a little bit lighter than the
other solutions and that does leave the
temperatures to go a little bit hotter
than some of the other boards here but
anything in my opinion under 90 degrees
20
4:7 is a good choice and they've done a
good job of implementing that we've also
got an eight plus four pin connectors up
the top here but even for my testing
here I'm only using a single 8 pin
connector and we don't go anywhere near
that because we've got thick gauge
wiring on a HX 1,000 watt power supply
so for the vrm they've got an excellent
implementation here which is slightly
more efficient and better than that of
the Vision G but they've also included
features on the back here like Wi-Fi 6
and Bluetooth 5 they're moving through
the onboard audio here we've got a
frequency response curve that's pretty
much completely flat - 2.3 decibel
drop-off with 10 Hertz and under so
again we'll power those mid-range cans
absolutely fine with a pretty clear
signal and in terms of crosstalk that
was - 89 decibels which is excellent and
then for noise suppression on the mic
they do have this and it's very tricky
because this is the first time I've
noticed it's a what I would call active
noise suppression I actually haven't
seen this before this board where it's
tricky to actually find out that it's
using noise suppression where I only
found out by plugging in my old Japanese
1980s vintage mic and you can see once
you unplugged it it then had to readjust
and in that time it was learning the
noise profile and cancelling that out
even while you talk the words so it is a
better generation and reiteration of
noise suppression but that being said it
still is noise suppression so it will
lower the quality of your voice by a
little bit but the benefit of that is
your friends you're gaming with online
and people you're just talking to online
are going to get a very clear voice
coming through it's just in the quality
of things noise suppression does take a
frequency out there that will affect the
quality of the voice recordings so the
onboard audio checks out absolutely fine
now moving through the BIOS this is
another thing I like about this board in
particular was that it was a good
experience
I couldn't fault anything from the
baseline it's very simple to use
overclocking was a breeze and there was
no problems like I actually found on the
vision G when I was checking out that
BIOS so they've implemented a more
stable BIOS at this time around with the
Auris pro a
and also in the bias itself you've got
the smartphone utility which can tune
each of the total eight PWM fan headers
and their speeds now that being said I
would like to see RGB control within the
bias itself and you've also got a five
and twelve volt RGB headers down the
bottom and up the top four four in total
they're running through the PCIe slots
we've got three 16x slots where the top
one is actually only the true 16x and
then the one below that 8 X and then the
one at the bottom four X and then the
two in-between One X slots are also
there and in terms of m2 connectivity
we've got three M 2 X 4 slots though the
top one is reserved for PCA for then the
bottom two a PCA 3.0 and testing out the
speeds and temperatures they were
absolutely fine and we saw a maximum
temperature of 51 degrees so they're
doing a good job on the heatsink
implementation there they move through
the back of the board here we've got the
Wi-Fi 6 connection point with its own
included standalone antenna 10 USB ports
in total one of those being a USB 3
point to type C and it also got a 2.5 g
NIC you've also got a single HDMI 1.4
out and no ps2 port but manual 5.1
surround out and an optical out for your
audio and after all that it's time to
segue into a conclusion for you guys
where this board has it all the vrm
solutions really good the feature set
Wi-Fi 6 Bluetooth 5 and also the
heatsink design is a fin type design so
if you want to even go crazy on the
overclocks you can put a fan on that and
it will respond well the BIOS is also
really stable on this particular
motherboard and testing out ddr4 40 400
megahertz memory worked absolutely fine
as well as the over clocks on the 10
900k working absolutely fine too then
we've got the clean black as saying this
is another thing that I'm personally
digging about this board is that it's
just got such a nice look to it and I
think it's gonna go well with any type
of build that you're doing and of course
who can forget about a little bit of RGB
which you've got on the left-hand side
both the top and bottom so flipping the
board around now I really like this one
for that premium value if that's kind of
going to be a segment I think for me
personally that would be a segment
because
you're getting everything out of this
board that you would want on the premium
range but you're going away with things
like a fancy back plate on the rear of
the board and saving costs and so I like
the fact they've included tantalum caps
the bias responds really well to
overclocking you've got really good
onboard audio 2.5 g Nick all this other
stuff that is feature packed and it
doesn't break the bank too much 270 USD
that can handle their mainstream
flagship CPU overclock to the brink is a
really good feat but in terms of its
efficiency as well it's also coming
close to that of the Z 490 PG velocity'
which when I first took a look at that I
was really impressed with that - I'll
put a link to that review up here but in
terms of the Z 490 comparison this one
is definitely gonna be near the top of
the list I can tell you that now before
we even go into that comparison and I do
like this board against the vision G and
also the Auris master which I've already
tested both of those here in the studio
so this one is the one to get from
gigabyte it's got the hardware it's got
the feature set but they've also done a
good job this time around
with the BIOS and how they've
implemented the stability and that's
about it for today's review if you guys
enjoyed this one then be sure to hit
that like button for us or should I say
Oris and also let us know in the
comments section below that was a bad
joke wasn't it and anyway let us know in
the comment section below what you think
of the aesthetic what you think of the
results for this board and also what you
think of a price point in terms of a
motherboard what are you looking for if
you go with budget or premium love
reading your thoughts and opinions as
always just like this question of the
day here which comes from raw Denine and
they asked 1.5 volt how did it not fry
and they referring to the previous
vision G review that we did where that
was taking the motherboard to really
crazy voltages now one thing is well
with z4 naiti do not overclock the CPU
and leave the voltages on auto in the
past I've seen different motherboards
handle this all but in general z4 90s
are really just going crazy with the
auto voltages and so it will take it to
crazy levels and basically the reason
why it doesn't fry is because I identify
straight away whenever you test out any
CPU out of the box always get a baseline
with the power consumption it's using so
the
for instance the 10 900k that's using
around 190 to 200 watts at 4.9 Giga it's
all core
so there's your baseline now if you got
to 5.2 gigahertz and suddenly like some
of these bullets they're drawing 350
watts you know that that's just a stupid
amount of extra wattage for really
little performance gain so you know
straight away okay I've got to chain
this down I got to take things down and
I got to turn off the stress test
straightaway otherwise you could risk
frying your CPU and that's how simple it
is
so basically always get that baseline
and then go from there
so around 260 watts is where it goes for
5.2 Giga it's all core that's a pretty
fair level it's pretty much topping out
at that and I won't go any real that
much higher especially for 24/7 use and
that pretty much does it for today's
video if you guys have stayed this far
and you're enjoying that content and you
want to see it the moment it drops then
be sure to hit that sub button ring that
bell and I'll catch it in another tech
video very soon peace out for now be
