if you've seen my review of the Xiaomi notebook 13 this is the 2017 model would
have seen that I could not install the latest Nvidia graphics driver but I've
been onto it they've released an update now and in the changelog it says it now
supports installation of the newest drivers on this right here so it's the
MX 150 with 2 gigabytes of dedicated ram and it is pretty basic aliy the same as
the 1030 now the new driver is installed here as you can see which is now three
eight five point two eight so I've got that in there running and then we have a
quick look at what kind of difference it makes and then follow up on a few
requests I've had people ask me if I can overclock the GPU and undervolt the CPU
which I will do later on so at the moment the CPU you can see here as at
the stock voltage I'll change it soon so I'm going to run Tomb Raider here so
this is the benchmark I've been using so to gauge the performance it's just easy
for me here so I'll run it first and we'll see if the driver and proves
anything and then we'll have a look at doing a little bit overclocking on the
GPU so just to show you that these settings are the same as before it's the
lowest preset 720p run that benchmark now and see the kind of results we get
from the driver update there's a result so nothing has really changed
58 frames per second is the school that I got on the older driver so the drivers
has not really given us any boost there whatsoever now that's fine so what I'm
going to try now is to just do a little bit of overclocking on the GPU I'm going
to under volt also the CPU so to do that I'm using intel extreme tuning utility
and I'll see here the core voltage offset for me on my system this is a
stable undervolt now if you go any higher it will just give me a blue
screen now that's going to vary from CPU to CPU so if you're going to be testing
this out on your model just keep going up in increments of 0.0 0.8 do some
asterisk in here as well that you have built into
the extreme tuning utility now you can also increase the turbo power limits
that I wouldn't touch that actually cuz that's not the aim here the aim here of
under vaulting is just to try and lower the temperatures a little maybe it'll
tip up a little bit higher now the overclock on the GPU here I have
discovered that putting more clock on the GPU the core is really pointless
because it's never going to get up to that boost speed so helpful up the
information here you can have a look on system information so the maximum boost
speed it will go up to while here it is 936 but it never gets up to that because
it just doesn't have the the thermal Headroom to do this so it's pointless to
add any clock to it but what I've discovered that the memory clock this is
going to seem crazy I can put a whole whopping gigabyte more of speed on there
and that is perfectly stable so it seems that what Nvidia have done or probably
show me has under clocked the ran there a little bit so having that bonus here
let's now run that test again and see what kind of results we get keeping an
eye to on these thermals
so it has given us a little bit of a boost I can see already 96 frames per
second this is just the start of the benchmark but I'll skip ahead now to the
results so the GPU Ram overclocked has given us approximately 5 frames per
second average booster which isn't too bad that's not a bad gain there so I
will actually try putting a little bit of higher clocks on the core clock here
of the GPU so and tweak this up now I just put first even though it's probably
not going to allow me to do this on many of these key data in 50 megahertz more
on the clock and we'll see what happens for some reason that's not sitting there
we go ok so that's given a tiny little boost more you can see it's just gone up
a frame or two more so it's not bad but let's have a look and see if I can even
push that further now I was thinking of the CPU GPU clock sorry was completely
pointless tweaking that but I'll try this as high as 70 because the thermals
are actually still quite good we're not getting too hot on there so far I can
see the maximum GPU temperature has been 70 degrees here which is fine so we'll
try plus 75 hopefully it's not going to lock up on me now if you see any
artifacts or things like that then you know that you're overclocking too much
and you really need to tweak back those speeds that you're putting on here of
course you do all of this at your own risk
so there we go that actually loved this caused a little so boosting that GPU
clock really isn't that beneficial at all but you can get a little bit as
you've seen from tweaking up the RAM there so now to have a look at thermals
I do have HW info running in the background here and oh actually no I
don't that has closed itself off for some reason but I can check here you can
see that the CPU package temperature maximum temperature is 75 degrees so
that is perfectly fine and now if we go back and have a look in MSI Afterburner
the maximum GPU temperature is 70 to 72 degrees so those temperatures are
perfectly fine where it does get of course like I pointed out in my
gaming review and my full review of this laptop is just here just above the vents
that gets up to actually go there we go 47 almost 48 degrees so very toasty to
the touch there it's almost getting up to it feels like it's going to burn new
kind of material there so that's why I always recommend with this laptop if you
are going to be gaming for extended periods get yourself a laptop cooler
that's probably going to help out a lot too with just improving performance
maybe but I won't actually be testing that myself because I really do not like
laptop coolers I like Portability and a machine that I can just pack up and put
in a bag and I'll have to lug around an extra accessory for it so there you go
you can see that the drivers made absolutely no difference in performance
but we can do a little bit of under vaulting and overclocking there of the
GPU to boost things up around what is that about eight or ten percent
performance which isn't too bad considering that's free performance
there that we're getting and I'll run that for a couple of days now with zero
problems I haven't noticed any artifacts from the memory so it seems to handle
that extra 1000 mega Hertz on the memory clock perfectly fine thanks for watching
this video and if you haven't already check out my full review of this model
Bye for now
