what's up guys Jays two cents here let's talk hypotheticals for a second let's just say you got your brand new fandangled graphics card AMD or Nvidia doesn't really matter this one's not new but you kind of get the idea right it's visual aid any been pretty content with it and you decide you want more performance but there's a there's a catch you're not willing to over volt or overclock because that's just scary and even though I've shown you it's easy and it's very safe and almost nothing can go wrong you're still not willing to change any of the core clock speeds on this thing but you want more performance can it be done yes it can and that's what we're going to talk about today how to get more performance out of your graphics card without actually having overclocked today's video is brought to you by mass drop and right now they have a drop going on the minivan custom mechanical keyboard kit featuring customizable key layouts tons of key cap choices extremely sturdy metal construction and all at only 40% of the size of a standard keyboard over 500 units have already sold so don't wait if you want to take advantage of this exclusive mass drop pricing now what I'm going to show you today actually applies to both AMD and NVIDIA well about 80% of it how's it going to apply to AMD well I'll explain why it's at 80% a second but I don't want any of the beginners or the newbies here to get left behind so if this sounds a bit redundant I apologize but you've got to understand some basics before you can actually understand what it is we're doing so you know how it works if you know how it works then you can actually play around and get some better results now Nvidia uses what's called GPU boost to allow the graphics card to self overclock as far as it can that's was considered reasonable and safe so the nice thing is you are usually going to get higher than advertised speeds within video graphics cards it's cicely GPU boost works now AMD also has a boost clock but it doesn't have a perimeter in there that allows it to go farther than what the predetermined boost clock is so whereas an Nvidia graphics card may say it has a seventeen hundred and sixty mega Hertz boost clock you might actually see eighteen hundred or higher on that because it realizes that hey we've got some Headroom here let's go farther so you can actually get higher than the advertised boost beats but AMD will go up to its boost clock and stay there it won't actually push itself any farther so that's why I say 80% of what you're going to see here actually applies to AMD because we're not going to be getting better than boost clock performance on AMD but NVIDIA you can see a benefit to that extra Headroom available to it with what we're going to do today now both AMD and NVIDIA use two key factors to control the clocks in their graphics cards and those being both temperature target which says don't let the graphics card exceed a certain temperature that we consider safe and the other being power limit or how much power this graphics card is allowed to draw at maximum now either of those two things can cause the graphics card to slow down if they start to approach that threshold both temperature and TDP independently now the nice thing about AMD and NVIDIA is both of them allow us to adjust the temperature target and the power target giving us more Headroom now why we want more Headroom even if we're not already hitting those limits well because as the temperature and the TDP start to approach those limits they will start to slow down that way it doesn't just suddenly bang its head against the roof of those limits so we'll start to kind of slow down that way we don't hit that limit really hard and abrupt because if it hits it really hard and it has to suddenly pull back power and frequency to keep from going over that's going to be noticed in a very jarring gaming experience of a sudden decrease in fps and that would be very very intrusive to your gaming experience so that's why things will kind of slowly start to kind of equalize as they get towards those limits fortunately we can adjust those and that's what we're going to do here today and one last thing I want to explain before we actually get into the demo here is the reason why you would actually want to increase the TDP and the temperature limit if you're not even already hitting those limits is because how the clock adjusts itself is not only dependent on how close it is to the actual limit but how much farther it can go before it hits that limit so if it sees there's a bigger gap between where it is and the limit it won't adjust itself nearly as much because it goes Wow we've got a long way to go so if we're at 16 we can go to 90 it goes well we've got 30 see here before we could have to start messing with ourselves so we can go a little farther so let's go ahead and turn here let's get into some testing and show you guys exactly what kind of tangible differences there are by adjusting just those two things now this is EBG a precision I'm using it because I have an Nvidia graphics card we're doing this with a 1080 founders edition right now if you have an AMD graphics card installed you can do what you're going to be seeing here with global wot manager inside of the Radeon settings application so you would go into games and go into global then go into the top tab and go to global wot manager I don't know if MSI Afterburner works with aim the new AMD with our X 480 stuff but you can also use msi afterburner on the older AMD graphics cards so this is what everything looks like by default and you can see the top two we have right here is power target at 100% and temp target at 83 see this little arrow here points to the prioritization this says base your your dynamic control on either power target or temperature now right now we're just going to leave it as is it's completely defaulted there's no change whatsoever and so we want to do is kind of get some baseline tests here so that we can see just how much gain we're going to get after all this video is not about necessarily the starting point or the particular graphics card or the cooler type it's about seeing how much gains you can get by adjusting these different settings right here so I'm going to be using Metro last light I'm running it in 1440p because I want to put a decent load on the graphics card we want to see you know we don't want to be too easy 1080p is a little bit too easy for this card 4k is still not really the norm for more most people so we'll be doing 1440p I'm going to run the test three times and we're going to because that's plenty of time to let the graphics card get hot and then we'll come back and we'll talk about the results see what kind of drop-off there is because of temperature limits and power targets adjust those settings and then see how much tangible gain there really was this Metro last light benchmark is extremely violent I don't condone this level of behavior although fun and in semi glorious it's very violent Wow who the hell my kidding I approve all right so here's the test right here and when this is all said and done put up graphs that way you guys can eat more easily see kind of the tangible differences here so our first run member we did three runs in 1440p ninety-nine point Oh frames per second average and then we came down to a ninety seven point nine frames per second average so one FPS drop and then a ninety seven point eight FPS average again I want like a point two FPS drop so our average across all three was 98 so we want to see if we can get this number right here the average across all three up now let's take a look what what's actually happening here on the chart I know that this is going to be like impossible for you guys to see but I'm just gonna have to kind of relate to we started off 1898 megahertz but we came all the way down to 1600 and seven which is actually the base clock for this graphics card because we hit 83 C which is the maximum that's allowed I know you guys can't read I apologize this right here 83 C even though we hit the maximum temperature that was allowed we also hit the maximum TDP so because of those two things the graphics card at this point was pretty much reducing its clocks because we reached the max of both TDP and temperature which is kind of the official definition of thermal throttling so yeah we lost all of the benefits of GPU boost so in long gaming sessions uh playing games you know for an hour - obviously it's going to put more of a load on this graphics card over time than just these three bench these three tests back to back which takes about ten minutes to complete yeah so obviously we want to see if there's any sort of benefit here so there was those tests right there I'm going to clear this history and here's what we're going to do now we're going to come back over here to our precision or in your case global watt manager if you're using AMD we are going to prioritize temperature we are going to keep the power target in the temperature target linked and we're going to put the power target as high as it would go all of your graphics cards going to be slightly different the 1080 happens to have a default of and we're going to leave it at 92 C for our prioritization on temperature so we're telling it don't start to really do anything until we get up to 92 C and then we're going to leave again the GPU clock off set at zero memory offset at zero we're not doing any sort of overclocking here but what we also want to do is we want to keep the temperatures under control and at the sacrifice of a little bit of noise we are going to come over here and take a look at the fan curve because the factory fan curve is actually very very very conservative on the nvidia side they don't let the GPU go any faster than 50% fan speed which if you're willing to let the card get a little bit noisier then you can actually get much better thermals so i'm not even going to make a custom fan curve i'm just going to select the aggressive curve here from the drop down there's a drop down here if you click on will do this again here i did it kind of quickly if you click the curve button inside of precision X you can go to the fan tab come down here click aggressive click OK it's now applied apply it you can see the fan speed jumped up already so here's what we're going to do we're going to do those three tests again and we're going to see if that average 98 FPS came up or not now obviously with the aggressive fan curve it's kind of noisy as you'll probably hear on the mic but one thing to keep in mind too is the blower style colors on AMD and NVIDIA are very very noisy so if you're running some sort of a custom cooler card like AC X or something then it's not going to be nearly as loud well the reason why I came on here right now is I want to point out that we are running at eighteen hundred and twenty three megahertz pretty much constant right now with the temperature sitting right around 70 to 73 C is sitting right around that range so as long as things stay constant then the frequency won't bounce around nearly as much either which is going to give you a higher FPS average and a better gaming experience so anyway I'm gonna let the benchmark continue here and then we'll see what happened alright so the three tests are done now this is the original test we did our baseline if you guys want to talk about tangible improvements remember weighted ninety-nine point oh eight a ninety seven point nine oh and then a ninety seven point eight five if you look here for a ninety eight average now if we look at all we did all we did if we look here again is we changed power target to the max and temp target to the max and a more aggressive fan curve two teeth to keep the temperatures under control because we don't want to hit 90 to see that's terrible so if we look at the differences here we now have an average of 104 point six eight 104.3 four and 104 point four five so you see there was no change whatsoever for an average of 104 point three three so when I say no change whatsoever I mean between these three tests you didn't see a steady decrease in speeds because as it was getting hotter it was slowing down so we actually gained what what is that six point three FPS on the average just by changing temperature limit power limit and the fan curve we didn't overclock we didn't add any extra core but we gained extra performance that's pretty damn awesome if you ask me so here's how the hairs how it worked out in chart forms you can kind of see the temperature differences there the power limit average differences and then the actual FPS differences now I think something I get asked quite often is well what if I have a custom card like this with multiple fans a big heat sink and it doesn't get anywhere near 83 see it only sits around 75 or 74 out of the box well here's the nice thing about these custom cards almost all of them have an increased power limit some of them will go as high as a hundred and thirty percent and because of that that means there's gonna be more voltage available to it and that means there's going to be more overclocking Headroom available to it so even though you still might not touch the actual core clocks on those cards any additional Headroom that you actually give to those perimeters are going to allow again for a higher boost clock an automatic boost clock and it's going to keep them from dynamically adjusting the frequency nearly as much as I said by keeping a huge margin of distance between current temperature and maximum the more distance you can get between those two numbers the better and more consistent your clocks are going to be with GPU boost and on the AMD side you're going to see nearly as much fluctuation to actually go to the boost clock and just stay there it won't change whatsoever but yeah you definitely want to take advantage of the additional cooling on these cards because again these custom cards still come with a pretty conservative fan curve and you can actually get much better cooling out of these guys and still not be anywhere near as loud as you know the 747 on the test bench behind me and you're still going to benefit just as much you'll see better and faster boost clocks than you would with something like that and the reason why you want to increase the power target as well is because believe it or not even though you keep the temperatures in check you might still see the same erratic frequency behavior because of the power limit now if you up the limit past 100 it means you're telling the graphics card and the BIOS it's okay to pool more power draw than the rated 180 watts and you're not going to hurt anything by that immediate actually sets that at a limit that's considered safe as long as you have adequate cooling so if you're going to increase the power target you have to increase the fan curve with it because it's going to give a little more voltage which is going to give you more of the automatic overclocking Headroom that GPU boost is going to take advantage of so if you were to increase the temperature limit to the 92 C and increase the fan curve you would see lower temperatures but not necessarily better clocks because it won't be able to go any far there with the amount of voltage in the amount of power limit that's available to it so that's why you kind of want to do all three of those things in conjunction with each other and have them work very harmoniously is like a triangular Trinity of amazing GPU voodoo magic so yeah power target temperature target and fan curve have to work together anyway guys thanks
