DaySky D-Book Pro - GPU Overclocking & Fix Thermals For 36% Performance Boost


DaySky D-Book Pro - GPU Overclocking & Fix Thermals For 36% Performance Boost 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 sogreat on it got up to 80 degrees and I've done some investigating herebecause normally these companies will put on some really cheap zoom or pasteand just take a look at this I'm gonna pull up now this is the heatsink for theCPU and they've used some like putty style almost like a thermal pad therethat is absolutely horrible what they've used is so no surprising that thisreaches 80 degrees it should actually be a lot less than that considering its fancooled and normally this processor is just passively cooled so in this videoI'm gonna repay stit i'm not going to repay the GPU which is right here to theright of the screen and we're going to have a look at the thermals once I dothe reap aced and also I'm gonna do a little bit of overclocking too now weirda warning when you're cleaning it just be careful with those resistors allaround the sides that you don't want to damage them if you damage one of themthen it's game over for the CPU and also make sure you're not touching your catyour dog and if you can and use a static anti-static bench there so you don't runinto any problems with that earth yourself as well so touch a computercase or something like that as always handy so I'm gonna use a little bit ofArctic's mx4 on this then you don't need to use a high quality compound becausethis is only gonna reach about 10 watts without the integrated GPU if you wereusing the integrated GPU and you don't have any power limits which I haven't atthe moment set I've got them disabled so yeah I've got a little bit too much onthere really but it doesn't matter now any excess there you can see I spilt alittle bit this is quite a poor sloppy job but I'm gonna use what's called thebegi method I spread it out now just with a little bit of a plastic bag on myfinger there just to make sure that it's gonna cover that die nicely there andwe've got full proper coverage of that because I mean you can put a pea-sizedon there in the middle and it'll spread out evenly but like this I know that atleast I've got full 100 seen coverage right there and contact when I put theheatsink back on and screw that in place so now get that heatsink back in placeand simply just place it on top of course and then we're gonna screw it inso you go from one end to the other diagonally to make sure you get evenpressure then so screwing one slide you can see I'vegot the upper left hand to unscrew turn no more screwing this right one here andnow I'm just putting in that last screw so hopefully this will drop temperaturesmaybe about five to ten degrees or so with this reap paste but that's not themain concern the main concern is the GPU which I'll move on to nets because thatgot up to 90 degrees in my testing after gaming for a few hours so with the GPUhere you can see the one gigabyte chip and another gigabyte chip there of theSamsung Ram we've got two gigabytes in total double data rate three and we dohave this ribbon cable that is covering one of the screws that we need to getaccess to now these ribbon cables the plugs are very delicate and I don't liketo touch them but of course we have two here so you have to live up lift up thislittle plastic tab and just be real careful about that see how I lifted thatup right that and then just slide that out and you just move that up and nowwe've got access to that screw we need to get off to get the heatsink off okayso let's have a look and see if they use that horrible thermal paste or that padjust like the CPU I know they've actually put some proper thermal pasteon this one which is good now because those GPU is getting up to almost 90degrees I'm gonna add a little bit more copper here I think that's the only wayreally to try and lower those temperatures and perhaps for somethermal pads on as well so I have a shim here that's 20 by 21 millimeter thicknow okay it does get a little bit close to those resistors either side but Ihave done this before in the past and I've had systems running for years likethis without any problems without it shorting out any of those littleresistors either side so that's my plan there that will go on the top and thenthe heatsink this will screw back on and it should apply even more pressure to tothat so hopefully that'll keep that on there nice and firm and hopefully lowertemperatures about 10 degrees so I've used the bag method again so the plasticbag has smoothed out that threw more paste on there giving a perfect niceeven layer there you can see and I didn't go overboard this time as I tookthat off camera so now to put this on top so you need to really position itright in the middle there just give it a tiny little wiggle edgestay there now I don't believe that that is going to slide around or move ifyou're worried about this then use some thermal adhesive between these two herebut I'm just going to go with the thermal paste as well because itnormally tends to stick it down and glue it in there quite well then it shouldn'tshift around as mentioned so I've got some thermal paste now on the heat sinkyou can see right there so again I've just used a plastic bag there to spreadit out nice and evenly and I'll put this on top now and screever II think inplace okay so it's a bit of a squeeze getting this on but I did some chicksbefore actually screwed it all in place that the lids still gonna fit on but itwill be now in contact with us touching and putting a little bit of pressure onbut that's good it's good to have that pressure as well flying down the topjust to make sure it's got even better contact there now to get this ribbonback and you simply have to just place it in there so slip it back in and it'sa little tricky to do you just got to try and get it and like about there soyou can see it's now in place you can push it in any further and then that tabjust clip it down so I'll show you a quick before-and-after so we got up to88 degrees in fact it was 90 degrees the maximum the GPU would get up to is now81 degrees max so we've improved it by about 9 degrees which is not a lot butthat's going to give me a little bit of headroom here to do some overclocking infact I'm already running an overclock and that temperature I showed you beforethe 88 degrees was with the clocks at stock so the more you overclock the CPUor the core of the GPU sorry then the hotter it's going to get there of coursenow this next part here is for really experts only and those that want to getmaximum performance so what I'm going to do now is show you how to flash a editedbios with overclocks onto it because you cannot change theclocks through something like afterburner msi afterburner I do havehere running but you cannot change the GPU clocks and video locked us out ofthis on the 9000 series I think that's the reason why now you can overclock thememory which I recommend to do to find out where a stable memory overclock isand you can use that later on so first off we have to get this right here whichis gpu-z now take a BIOS dump so you're going to save the BIOS tofile right here which I'm about to do now you can see and this will cause thescreen to probably freeze for a second now well thereby are saved we can nowedit it so we're going to do now is just get this program here now give you allof these files there's a link in the description this is called Maxwell toBIOS Tweaker and it's basically just an editor so we want to open that bar thatwe just dumped cuz this is the one we're going to flash right here I've actuallygot one that I've already done some edits on so this is for my own systemnow I tried the memory at - sorry 1215 you know this memory clock for me hasbeen perfectly fine and stable testing out all games for a couple of hours noartifacts no glitches this is really good now my clock I've got a boost clockhere of twelve thousand and twenty five that's what I'm gonna test out andthat's all I have changed he's saved save it once you do the edits to theboost clock right here and then the memory clock the power table I think youmight actually need to adjust this as well sorry not the power table the boosttable this one here I've set that to the max clock of what my max boost is goingto be right here so that's that there then you tap on save BIOS and now we'regonna flash that over so this part is risky and I don't remem in doing this ifyou don't want to take this risk if you don't want to accidentally end upbreaking the 940m then please do not continue with this here this is all atyour own risk but this is getting the maximum performance out of the GPU and Iwill show you the results afterwards that it does boost it up quite a bit sonow we need to head to the device manager so right click the Windows Startbutton device manager and we're going to basically disable the GPU so we canflash it this has to be done otherwise you will not be able to flash it so yougo to display adapters and then click on the NVIDIA GeForce and sorry I have thistouchpad it's such a pain to use and right click it and then disabled deviceso once that happens it will be then disabled we're ready to flash and now weneed to go down to the command prompt and we need to run this as admin so justtype and see him in the search bar this is the easiestway to do this and then right-click that and run as administrator' so with thefiles I have to download and the description of there's the link therethe download extract that to your C Drive which I have already done and it'sa folder called MV flash this is the program used to flash it so I need tothen move over to that folder so I've already got some commands here just tomake things a little quicker for this video so I'm going to paste that in hereso what I'm doing else is changing the file over to NV flash and now I'mrunning this command here so this command basically what it's doing isindex 0 is going to be the NVIDIA GPU because we do have two GPUs on thesystem the integrated Intel one and now it's gonna select that and now it'sgoing to flash my rom called ROM now how original ROM ROM so that's going tostart to flash it now you can see it come up now it'll tell you the boardversion all of this should be the same the IDs if there's any difference in itdo not flash them update this play adapter so you hit yes you'll hear alittle bit from the speakers and now it's telling me that it is flashing thatokay so that's it it seems so simple of course I'm making this process look alittle simple here so it's now flashed those custom clocks over to the GPU youwant to go back into the device manager now and just right-click this of courseand enable the device again we want that GPU back on line and now reboot your PCand those clocks should take if you didn't run into any issues but make sureyou got that backup of the original bios just in case you do something wrongthere now we have a look at the performance difference from stock tooverclocked now to get a gauge on what kind of improvements we can't expectwhen you do a little bit overclocking so I always knew that the Maxwellarchitecture in the past that it does overclock quite well especially on thedesktop cards so this is the stock score here of the heav'n benchmark that Ishowed in my full review now with my overclock with 1300 on the core clockthat I flashed that BIOS and 1250 on the RAMcheck out this difference so it's gone up now to 452 so what does that meanthat's actually about 36 percent improvement there on that score so thatis massive huge difference there gained from overclocking so this is nowGeekbench 4 this is the default score again no overclocking here 22,000 verylow not very good at all and then with my overclock it's almost hits now 30,000so that is a big improvement that is around 25 26% increase there not as goodas heaven so it's going to vary but I will check this out now we'll take alook at Grand Theft Auto 5 and see if the framerate has also improved there sowe run it with these same settings I did in my review so 720p on the lastsettings here and performance to me has improved around about 3 to 4 frames persecond see I'm getting about 34 frames per second at the moment the problemwith this game here like most modern titles as it needs a lot more powerfulCPU in it the system is bottlenecked by of course the CPU you can see it'srunning at 100% and the GPU is not even running at maximum capacity it's onlyabout 50% there so it really hasn't made too much of a difference the game isstill playable of course it's 720p it's just that problem there with the GPUreally maxing things out you can see outside here now 34 or 35 frames persecond this is actually not bad at all and I would say yeah about 4 frames persecond more and after my overclocking you can see that the rise of the TombRaider this school has increased quite a bit as well giving us about an extraseven or eight frames per second in 720p on the lowest settings which is quite anincrease so there we go you can see that a repast and adding that extra copperhas made a huge difference to the thermals and I was able to do quite abit of overclocking here and reasonably good results out of that I mean it'sboosted the performance around 25% for the GPU but the problem with this laptoplike I mentioned in my review is that a lot of these games the newer titles willbe limited in bottlenecks by that weak cell run in 3450 CPU so that's the main problem with this laptop here but good to see that wecan at least increase the performance now I didn't really comment much on theCPU dermals because it doesn't actually go over 60 degrees c now with me applyingthat repai stew it so definitely recommend that if you are going to getthis laptop or you have one then at least do a repostand a little bit of caution there with flashing the bios to the GPU because ifthings go wrong you could end up with having a completely bricked and video940m which wouldn't be great thanks a lot for watching this video and I dohope to see you back in the channel bye for now .
