Mi Notebook Air 13 2017 CPU Undervolting & MX150 Overclocking if you've seen my review of the Xiaominotebook 13 this is the 2017 model would have seen that I could not install thelatest Nvidia graphics driver but I've been onto it they've released an updatenow and in the changelog it says it now supports installation of the newestdrivers on this right here so it's the MX 150 with 2 gigabytes of dedicated ramand it is pretty basic aliy the same as the 1030 now the new driver is installedhere as you can see which is now three eight five point two eight so I've gotthat in there running and then we have a quick look at what kind of difference itmakes and then follow up on a few requests I've had people ask me if I canoverclock the GPU and undervolt the CPU which I will do later on so at themoment the CPU you can see here as at the stock voltage I'll change it soon soI'm going to run Tomb Raider here so this is the benchmark I've been using soto gauge the performance it's just easy for me here so I'll run it first andwe'll see if the driver and proves anything and then we'll have a look atdoing a little bit overclocking on the GPU so just to show you that thesesettings are the same as before it's the lowest preset 720p run that benchmarknow and see the kind of results we get from the driver update there's a resultso nothing has really changed 58 frames per second is the school thatI got on the older driver so the drivers has not really given us any boost therewhatsoever now that's fine so what I'm going to try now is to just do a littlebit of overclocking on the GPU I'm going to under volt also the CPU so to do thatI'm using intel extreme tuning utility and I'll see here the core voltageoffset for me on my system this is a stable undervolt now if you go anyhigher it will just give me a blue screen now that's going to vary from CPUto CPU so if you're going to be testing this out on your model just keep goingup in increments of 0.0 0.8 do some asteriskin here as well that you have built into the extreme tuning utility now you canalso increase the turbo power limits that I wouldn't touch that actually cuzthat's not the aim here the aim here of under vaulting is just to try and lowerthe temperatures a little maybe it'll tip up a little bit highernow the overclock on the GPU here I have discovered that putting more clock onthe GPU the core is really pointless because it's never going to get up tothat boost speed so helpful up the information here you can have a look onsystem information so the maximum boost speed it will go up to while here it is936 but it never gets up to that because it just doesn't have the the thermalHeadroom to do this so it's pointless to add any clock to it but what I'vediscovered that the memory clock this is going to seem crazy I can put a wholewhopping gigabyte more of speed on there and that is perfectly stable so it seemsthat what Nvidia have done or probably show me has under clocked the ran therea little bit so having that bonus here let's now run that test again and seewhat kind of results we get keeping an eye to on these thermals so it has given us a little bit of aboost I can see already 96 frames per second this is just the start of thebenchmark but I'll skip ahead now to the results so the GPU Ram overclocked hasgiven us approximately 5 frames per second average booster which isn't toobad that's not a bad gain there so I will actually try putting a little bitof higher clocks on the core clock here of the GPU so and tweak this up now Ijust put first even though it's probably not going to allow me to do this on manyof these key data in 50 megahertz more on the clock and we'll see what happensfor some reason that's not sitting there we go ok so that's given a tiny littleboost more you can see it's just gone up a frame or two more so it's not bad butlet's have a look and see if I can even push that further now I was thinking ofthe CPU GPU clock sorry was completely pointless tweaking that but I'll trythis as high as 70 because the thermals are actually still quite good we're notgetting too hot on there so far I can see the maximum GPU temperature has been70 degrees here which is fine so we'll try plus 75 hopefully it's not going tolock up on me now if you see any artifacts or things like that then youknow that you're overclocking too much and you really need to tweak back thosespeeds that you're putting on here of course you do all of this at your ownrisk so there we go that actually loved thiscaused a little so boosting that GPU clock really isn't that beneficial atall but you can get a little bit as you've seen from tweaking up the RAMthere so now to have a look at thermals I do have HW info running in thebackground here and oh actually no I don't that has closed itself off forsome reason but I can check here you can see that the CPU package temperaturemaximum temperature is 75 degrees so that is perfectly fine and now if we goback and have a look in MSI Afterburner the maximum GPU temperature is 70 to 72degrees so those temperatures are perfectly fine where it does getof course like I pointed out in my gaming review and my full review of thislaptop is just here just above the vents that gets up to actually go there we go47 almost 48 degrees so very toasty to the touch there it's almost getting upto it feels like it's going to burn new kind of material there so that's why Ialways recommend with this laptop if you are going to be gaming for extendedperiods get yourself a laptop cooler that's probably going to help out a lottoo with just improving performance maybe but I won't actually be testingthat myself because I really do not like laptop coolers I like Portability and amachine that I can just pack up and put in a bag and I'll have to lug around anextra accessory for it so there you go you can see that the drivers madeabsolutely no difference in performance but we can do a little bit of undervaulting and overclocking there of the GPU to boost things up around what isthat about eight or ten percent performance which isn't too badconsidering that's free performance there that we're getting and I'll runthat for a couple of days now with zero problems I haven't noticed any artifactsfrom the memory so it seems to handle that extra 1000 mega Hertz on the memoryclock perfectly fine thanks for watching this video and if you haven't alreadycheck out my full review of this model Bye for now .
