Hey how's it going Dave QD here so we need to preface this video with a pretty big disclaimer everything I talk about in this video you kind of do it at your own discretion because opening up your computer fiddling with stuff playing with software that affects like under volting and bios and stuff like that you kind of do that your own risk because there's always an element of risk to err right I think it's safe I created this video I have experimented with it extensively but it is at your own risk okay this video is about two powerful tweaks that can greatly improve the performance of your laptop and there's two parts to it first is a software it's a relatively easy tweak super safe and then the second part involves opening up your laptop to apply thermal compounds it's something a little more dicey but it should keep your warranty intact as long as you don't tell anyone about it okay the first thing we're going to look at is the software and this officer will give you tremendous control over your CPU and if you just start clicking things randomly yeah you can mess things up but we're going to be dealing with one thing which is under bolting and it's super safe under bolting is a process where you reduce the voltage that's going to the CPU but it doesn't affect performance at all and the reason why you can do this safely it's because CPUs are fed more voltage than they actually need it's just a matter of finding that sweet spot the two more popular apps that people use for this are XTU by Intel and throttle swap both are free both are good but for beginners I would recommend X to you because it has all the basic components you need to properly under volt this is XTU when you first load it up I know it looks crazy complex lots of numbers but we can ignore most of it first let's adjust the graphing monitor to show 30 minutes of data we're going to stress test your CPU at its baseline without any adjustments just to see what numbers were getting so this is the XPS 15 95/60 it's running a KB Lake 7700 HQ the during the stress test the CPU is running pretty much Full Tilt occasional dip and the temperatures are going up and down as a fan turn on and off at its hottest it's 88 degrees and at the coolest around 75 76 degrees now the way to undervolt properly is to throw out the voltage run a stress test and if it checks out drop the voltage again and repeat you're basically starving the CPU more and more and so to do that in XP you you go to advanced tuning and on the score tab you click on the core voltage offset and you want to scroll upwards from 0 to see negative numbers remember we're under vaulting here so you want to choose a negative number so we're going to start with an under volt of 50 millivolts so I'm going to reduce it by 0.05 zero volts and when I run the stress test now we're getting a max of 83 84 degrees for a couple of clicks not bad right system is still completely stable we're getting full clock speeds and to step in the right direction ok then we're going to kick it up a notch and I'm going to reduce it by a hundred and twenty millivolts which is negative zero point one two zero volt and I'm cheating here because I know this is near the limit for this particular CPU you should reduce it one increment at a time and test a bit but for the sake of speed I'm cranking that knob to ten so at this under volts when we stress test and activate the graph we're getting even lower temperatures maxing at around 77 degrees so a good 10 or 11 degree drops from the original unaltered voltage so just to demonstrate I'm going to drop my voltage to negative 130 millivolts I know it's going to freeze because I've done this before my even blue screen and when it does that's when we know you hit the under volt limit and when you're there reboot go back into XTU and go back to the last voltage that worked and for me that was negative 120 and that's your limit to really test the stability you want to run something like prime95 overnight just to make sure it's all good if it doesn't last overnight bump up the voltage now every CPU is different so it's tough for me to tell you exactly where to start but I would recommend looking up your CPU or your particular laptop and seeing what other users with that hardware have been able to unravel to and just kind of use it as a starting guide for the KB Lake 7700 HQ I would start around 100 millivolts so that's negative zero point one zero zero volts for the skylake 6700 hqi under volts at around 150 millivolts so that's negative zero point one five zero volt and when you're done you can close X Q down the settings apply even on reboot you don't have to keep the front end application open so under bolting laptops can give you better thermals but in my experience the best results come from something called repay Seng okay when a laptop manufacturer makes a lot op there comes a point in the manufacturing process when someone or something usually person has to apply a thermal paste onto the CPU and the GPU and usually they don't do an amazing job usually in a rush it's like a person who's doing like hundreds of laptops I just made that number up but they're doing a lot of laptops every day and they're just squirting pay so they don't really give that much attention to each CPU what ends up happening is the application is imperfect usually there's too much and there's a good chance they're not using the best quality thermal paste there's nothing super terrible about this the laptop will perform to spec but it'll run hot to resolve this we're going to reapply that thermal paste and we're going to use better quality stuff which results in lower temperatures so for the uninitiated thermal paces of goopy stuff that you apply on to CPUs or GPUs to help transfer heat away from it and the better quality paste that you use and the better the application process the better of a job that it does again every laptop is different so you'll have to search around to see if people have done it on yours but the more popular laptops tend to have some kind of guide or tutorial as to how to do it for the XPS 15 once you're inside carefully unplug the battery loosen up the screws here carefully remove the heat pipe assembly and then clean off the original paste using alcohol or arctic cleaner or whatever you want and then apply some good thermal paste so I tend to do a small blog for the GPU and then a small line for the CPU just use good quality paste I like arctic filter 5 you don't need a lot but you're better off using too much then way too little on some laptops you'll see thermal pads you can swap those out for better quality ones or potentially dictor ones basically you want the thermal pad to eliminate any kind of air gap and then when you're done place the heatsink back on but don't lift up to check how you did just trust because if you lift it up you can put air bubbles into the paste and that's no good one other thing was kind of unique the XPS 15 this area here has voltage regulator modules that get pretty warm I've always put throne pads over this area just to help transfer the heat to the aluminium paneling and in the end the reap Aysen gives you a further drop in temperature better battery life fans that come on less and most importantly no more CPU throttling your laptop will be able to run at maximum clock speed for as long as it wants and if you play games render videos or just do anything that pushes your laptop hard you're going to get some nice performance gains from this the thing is some people going to watch this video and they're just going to jump to conclusion that this is the best thing ever it's cool it's awesome but it's not for everyone if you've never opened your computer before if you don't know what thermal paste is you've never used it before you can still learn and figure out how to do this stuff and it's great once you do but take your time do the research understand what you're doing before you do it because there is an element of risk to this I really don't want you breaking your laptop's just because you were a little overzealous take your time do properly hope you guys enjoyed this video thumbs of you liked it sub CB loved it see you guys next time
