I go so I'm back here with the DaySky D-Book Pro now if you've seen my review
of that one that the thermals weren't so great on it got up to 80 degrees and
I've done some investigating here because normally these companies will
put on some really cheap zoom or paste and just take a look at this I'm gonna
pull up now this is the heatsink for the CPU and they've used some like putty
style almost like a thermal pad there that is absolutely horrible what they've
used is so no surprising that this reaches 80 degrees it should actually be
a lot less than that considering its fan cooled and normally this processor is
just passively cooled so in this video I'm gonna repay stit i'm not going to
repay the GPU which is right here to the right of the screen and we're going to
have a look at the thermals once I do the reap aced and also I'm gonna do a
little bit of overclocking too now weird a warning when you're cleaning it just
be careful with those resistors all around the sides that you don't want to
damage them if you damage one of them then it's game over for the CPU and also
make sure you're not touching your cat your dog and if you can and use a static
anti-static bench there so you don't run into any problems with that earth
yourself as well so touch a computer case or something like that as always
handy so I'm gonna use a little bit of Arctic's mx4 on this then you don't need
to use a high quality compound because this is only gonna reach about 10 watts
without the integrated GPU if you were using the integrated GPU and you don't
have any power limits which I haven't at the moment set I've got them disabled so
yeah I've got a little bit too much on there really but it doesn't matter now
any excess there you can see I spilt a little bit this is quite a poor sloppy
job but I'm gonna use what's called the begi method I spread it out now just
with a little bit of a plastic bag on my finger there just to make sure that it's
gonna cover that die nicely there and we've got full proper coverage of that
because I mean you can put a pea-sized on there in the middle and it'll spread
out evenly but like this I know that at least I've got full 100 seen coverage
right there and contact when I put the heatsink back on and screw that in place
so now get that heatsink back in place and simply just place it on top of
course and then we're gonna screw it in so you go from one end to the other
diagonally to make sure you get even pressure then
so screwing one slide you can see I've got the upper left hand to unscrew turn
no more screwing this right one here and now I'm just putting in that last screw
so hopefully this will drop temperatures maybe about five to ten degrees or so
with this reap paste but that's not the main concern the main concern is the GPU
which I'll move on to nets because that got up to 90 degrees in my testing after
gaming for a few hours so with the GPU here you can see the one gigabyte chip
and another gigabyte chip there of the Samsung Ram we've got two gigabytes in
total double data rate three and we do have this ribbon cable that is covering
one of the screws that we need to get access to now these ribbon cables the
plugs are very delicate and I don't like to touch them but of course we have two
here so you have to live up lift up this little plastic tab and just be real
careful about that see how I lifted that up right that and then just slide that
out and you just move that up and now we've got access to that screw we need
to get off to get the heatsink off okay so let's have a look and see if they use
that horrible thermal paste or that pad just like the CPU I know they've
actually put some proper thermal paste on this one which is good now because
those GPU is getting up to almost 90 degrees I'm gonna add a little bit more
copper here I think that's the only way really to try and lower those
temperatures and perhaps for some thermal pads on as well so I have a shim
here that's 20 by 21 millimeter thick now okay it does get a little bit close
to those resistors either side but I have done this before in the past and
I've had systems running for years like this without any problems without it
shorting out any of those little resistors either side so that's my plan
there that will go on the top and then the heatsink this will screw back on and
it should apply even more pressure to to that so hopefully that'll keep that on
there nice and firm and hopefully lower temperatures about 10 degrees so I've
used the bag method again so the plastic bag has smoothed out that threw more
paste on there giving a perfect nice even layer there you can see and I
didn't go overboard this time as I took that off camera so now to put this on
top so you need to really position it right in the middle there just give it a
tiny little wiggle edge stay there now I don't believe that that
is going to slide around or move if you're worried about this then use some
thermal adhesive between these two here but I'm just going to go with the
thermal paste as well because it normally tends to stick it down and glue
it in there quite well then it shouldn't shift around as mentioned so I've got
some thermal paste now on the heat sink you can see right there so again I've
just used a plastic bag there to spread it out nice and evenly and I'll put this
on top now and screever II think in place okay so it's a bit of a squeeze
getting this on but I did some chicks before actually screwed it all in place
that the lids still gonna fit on but it will be now in contact with us touching
and putting a little bit of pressure on but that's good it's good to have that
pressure as well flying down the top just to make sure it's got even better
contact there now to get this ribbon back and you simply have to just place
it in there so slip it back in and it's a little tricky to do you just got to
try and get it and like about there so you can see it's now in place you can
push it in any further and then that tab just clip it down so I'll show you a
quick before-and-after so we got up to 88 degrees in fact it was 90 degrees the
maximum the GPU would get up to is now 81 degrees max so we've improved it by
about 9 degrees which is not a lot but that's going to give me a little bit of
headroom here to do some overclocking in fact I'm already running an overclock
and that temperature I showed you before the 88 degrees was with the clocks at
stock so the more you overclock the CPU or the core of the GPU sorry then the
hotter it's going to get there of course now this next part here is for really
experts only and those that want to get maximum performance so what I'm going to
do now is show you how to flash a edited bios with overclocks
onto it because you cannot change the clocks through something like
afterburner msi afterburner I do have here running but you cannot change the
GPU clocks and video locked us out of this on the 9000 series I think that's
the reason why now you can overclock the memory which I recommend to do to find
out where a stable memory overclock is and you can use that later on so first
off we have to get this right here which is gpu-z now take a BIOS dump so you're
going to save the BIOS to file right here which I'm about to do
now you can see and this will cause the screen to probably freeze for a second
now well thereby are saved we can now edit it so we're going to do now is just
get this program here now give you all of these files there's a link in the
description this is called Maxwell to BIOS Tweaker and it's basically just an
editor so we want to open that bar that we just dumped cuz this is the one we're
going to flash right here I've actually got one that I've already done some
edits on so this is for my own system now I tried the memory at - sorry 1215
you know this memory clock for me has been perfectly fine and stable testing
out all games for a couple of hours no artifacts no glitches this is really
good now my clock I've got a boost clock here of twelve thousand and twenty five
that's what I'm gonna test out and that's all I have changed he's saved
save it once you do the edits to the boost clock right here and then the
memory clock the power table I think you might actually need to adjust this as
well sorry not the power table the boost table this one here I've set that to the
max clock of what my max boost is going to be right here so that's that there
then you tap on save BIOS and now we're gonna flash that over so this part is
risky and I don't remem in doing this if you don't want to take this risk if you
don't want to accidentally end up breaking the 940m then please do not
continue with this here this is all at your own risk but this is getting the
maximum performance out of the GPU and I will show you the results afterwards
that it does boost it up quite a bit so now we need to head to the device
manager so right click the Windows Start button device manager and we're going to
basically disable the GPU so we can flash it this has to be done otherwise
you will not be able to flash it so you go to display adapters and then click on
the NVIDIA GeForce and sorry I have this touchpad it's such a pain to use and
right click it and then disabled device so once that happens it will be then
disabled we're ready to flash and now we need to go down to the command prompt
and we need to run this as admin so just type and see him
in the search bar this is the easiest way to do this and then right-click that
and run as administrator' so with the files I have to download and the
description of there's the link there the download extract that to your C
Drive which I have already done and it's a folder called MV flash this is the
program used to flash it so I need to then move over to that folder so I've
already got some commands here just to make things a little quicker for this
video so I'm going to paste that in here so what I'm doing else is changing the
file over to NV flash and now I'm running this command here so this
command basically what it's doing is index 0 is going to be the NVIDIA GPU
because we do have two GPUs on the system the integrated Intel one and now
it's gonna select that and now it's going to flash my rom called ROM now how
original ROM ROM so that's going to start to flash it now you can see it
come up now it'll tell you the board version all of this should be the same
the IDs if there's any difference in it do not flash them update this play
adapter so you hit yes you'll hear a little bit from the speakers and now
it's telling me that it is flashing that okay so that's it it seems so simple of
course I'm making this process look a little simple here so it's now flashed
those custom clocks over to the GPU you want to go back into the device manager
now and just right-click this of course and enable the device again we want that
GPU back on line and now reboot your PC and those clocks should take if you
didn't run into any issues but make sure you got that backup of the original bios
just in case you do something wrong there now we have a look at the
performance difference from stock to overclocked now to get a gauge on what
kind of improvements we can't expect when you do a little bit overclocking so
I always knew that the Maxwell architecture in the past that it does
overclock quite well especially on the desktop cards so this is the stock score
here of the heav'n benchmark that I showed in my full review now with my
overclock with 1300 on the core clock that I flashed that BIOS and 1250 on the
RAM check out this difference so it's gone
up now to 452 so what does that mean that's actually about 36 percent
improvement there on that score so that is massive huge difference there gained
from overclocking so this is now Geekbench 4 this is the default score
again no overclocking here 22,000 very low not very good at all and then with
my overclock it's almost hits now 30,000 so that is a big improvement that is
around 25 26% increase there not as good as heaven so it's going to vary but I
will check this out now we'll take a look at Grand Theft Auto 5 and see if
the framerate has also improved there so we run it with these same settings I did
in my review so 720p on the last settings here and performance to me has
improved around about 3 to 4 frames per second see I'm getting about 34 frames
per second at the moment the problem with this game here like most modern
titles as it needs a lot more powerful CPU in it the system is bottlenecked by
of course the CPU you can see it's running at 100% and the GPU is not even
running at maximum capacity it's only about 50% there so it really hasn't made
too much of a difference the game is still playable of course it's 720p it's
just that problem there with the GPU really maxing things out you can see
outside here now 34 or 35 frames per second this is actually not bad at all
and I would say yeah about 4 frames per second more and after my overclocking
you can see that the rise of the Tomb Raider this school has increased quite a
bit as well giving us about an extra seven or eight frames per second in 720p
on the lowest settings which is quite an increase so there we go you can see that
a repast and adding that extra copper has made a huge difference to the
thermals and I was able to do quite a bit of overclocking here and reasonably
good results out of that I mean it's boosted the performance around 25% for
the GPU but the problem with this laptop like I mentioned in my review is that a
lot of these games the newer titles will be limited in bottlenecks by that weak
cell run in 34 50 CPU so that's the main problem with
this laptop here but good to see that we can at least increase the performance
now I didn't really comment much on the CPU dermals because it doesn't actually
go over 60 degrees c now with me applying that repai stew it so definitely
recommend that if you are going to get this laptop or you have one then at
least do a repost and a little bit of caution there with
flashing the bios to the GPU because if things go wrong you could end up with
having a completely bricked and video 940m which wouldn't be great thanks a
lot for watching this video and I do hope to see you back in the channel bye
for now
