hey run welcome back to another ask GN we're getting down to the wire the last probably handful of videos we'll be shooting here before moving over to the office for shooting and this one we've got some good questions including one asking out when a trip LTT two who might happen so we talking about that today and as always leave your questions in the comment section below and we'll try to get to them for next week we also have a patreon bonus episodes that we're shooting three today two will go live on the main channel third one on patreon.com slash gamers Nexus if you want a bonus ask GN episode before that this video is brought to you by NZXT is new h 500 case which we recently found to have an impressively effective cooling setup that is entirely negative pressure when stock the H 500 is the successor of the s 340 and s 340 a lead offering high build quality that's all steel and glass and kale management features that are also a top class for the $70 compact mid tower case H 500 is a part of NZXT Zanu H series lineup which also features options from Mini ITX micro ATX and full ATX builds learn more at the link in the description below so the quick update before beginning this one as usual we saw have mod mats in stock getting a little low now probably gonna be placing another order pretty soon but if you want one place your order because we typically have about a month hold time while we wait for production once they run out so we still have them now they're on stored at Garren's nexus net as are the restock shirts and most designs and we have the video card Anatomy poster there as well so let's go to the first question first one is from budget gaming PC who asked any news on the hashtag rip LTT challenge or ice he said hashtag rip llt but really it's all the same at this point so I spoke to them about that LT AK seems like a good opportunity went up to Alex who's on minuses team and is the one who originally did the overclock that we beat so alex is the one who was really the Challenger and the challenge e in this scenario and one up to heaven as are you guys you guys gonna respond or like you know what's going on so they they actually do have some responses planned but I don't know it'll happen so we'll see I did talk to Alex a bit about it it sounds like it'll be a lot of fun if he can do what he wants to do it's just a matter of making sure the timelines work with all the launchers coming up like thread referred to for example so everyone's got a lot going on with that and other CPU tests things like that going on so we'll see it seems like they have a rough idea and desire to respond they just haven't prioritized it yet so if you want to encourage Alex to work on there rip LT or the RIP GN I guess response then I think you just probably tweet at Alex a great ish I think that's his Twitter handle and let him know you're interested all right so next why I definitely want to do a repel tt-to but it's not that much fun if I'm just one up in myself so next one is from Zeno nuke who says ask GN any update on the limited edition foil shirts can't remember if a timeline was given yes so those were pre-orders the update is that we have just we're in production so they're gonna be shipping to us soon and we'll be shipping out to all of you so I don't have a hard time line but they're in production now won't take too long to make them and they'll be going out soon if anyone has questions on that by the way email support at gamers Nexus net that's what the support accounts there for and he can help out further next one is from m3 ll0 who says I know you can't address every question so I'm going to repeat my last one I was wondering how different workloads on GPUs can cause different power consumption and temperatures all of them while showing 100% usage for example my overclocked arts 480 super position pulls about 170 watts according to GP z while fer mark just gets about 150 watts on CPUs ik clearly is related to the instruction set like a vxf MA or there are also different instruction sets on GP 3d loads so similar ideas as far as temperatures temperatures more or less correspond with power consumption but there's one instance here that's a bit different with GPUs GPU temperature can be influenced by a whole lot of things since the there's so much variance between the actual cards that are made so the vr m as an example on GPUs whether it's a good or a bad one will heavily dictate thermals in general including on the GPU because the vr i'm surrounds the GPU it also dictates efficient see for the just for 12-volt power as far as what causes the power consumption differences instruction set matters but also things like memory consumption so how memory intensive an application or a task is will impact how much power is being used because each of those memory modules takes couple watts or more depending on what it is if it's h BM or GG gr 5 or whatever so each of those modules takes power HP m a bit less per gigabyte than gddr5 anyway and if it's memory intensive then you've got that consideration if it's not memory intense if you have to figure out where's where's the load coming from typically it's the core but there are power virus scenarios as well so fir mark would be a great example of power virus where the clock rates are actually much much lower than what the card can achieve so you might see like thirteen hundred megahertz in seven mm infer mark but it's still burning really hot and that's because it's it effectively behaves like a power virus the literal power virus says in a malware that would drive power consumption to just try a component so that's that's the idea fir marks a pretty abusive program it's good for stress testing in some ways not recommended all the time but it's fine but the point is that that particular application really strains the VRMs and so all of your heat production is coming off the VRMs on that with some core and depend on other benchmarks you may have memory bandwidth intensive stuff you may have memory capacity intensive tests texture filtrations and other things so if you're working with a lot of like raw unfiltered textures or if you're working with textures that are high resolution not that compressible things like that then you get a lot of memory thrashing and that increases your power consumption on the memory where you might have less on the core if the core sitting around idle waiting for the memory to get kicked into gear so depending on which components waiting on the other one if any at all then that can impact power consumption too and then type of workload of course matters so it fur marks the best example because you can compare fur mark versus 3d mark graphics versus a game and they'll all have different power consumption despite being a high percent load and it's because they're doing different things for mark abusing the power on the power delivery on the vrm and games might be executing to working with different shaders so when you talk about driver optimization that's a big thing is it achieving its the graphics just via unoptimized brute force methods or have the drivers been optimized to leverage different parts of the GPU so for example asynchronous compute with something like Volta like the Titan V async compute those much better on the Titan V then on Pascal and whether or not that's leverage depends partially on the game personally on the drivers whatever so that's another consideration too but basically it's it's the type of instruction coming down the pipe impacts how much power is being to use just like a CPU so everything you said about CPU example if more or less applies here except we have the consideration of all the components surrounding the GPU in a really sort of tight grid so those can impact the thermals of the GPU too and I think our sustained frequency is a big one for how long a frequency is sustained fixed versus how much it's allowed to bounce up and down that impacts it vrm efficiency under certain loads voltage required to sustain that frequency versus the particular instruction being performed so fir mark again higher voltage typically to sustain the frequencies and all of those greatly impact the power consumption fan speed also impacts power consumption if you allow it to sit auto then that'll change your test your output for power consumption next one is from someone whose name is listed as a whore or I or who loses och if there's actually Thomas is how we know him so Thomas is the individual I met at LT axe the the sixth grader who said that he got bored of Linus started watching us and then said he got we were no longer in depth enough for him and he started watching builds right so he posted another question and said for the next ask GN could you explain what BC L K is and does it require a voltage increase when overclocking it so BC L K is base clock as many of you likely know you have to get a frequency for a processor when you look in BIOS you'll see the base clock you'll see them pliers and then memory also has a multiplier a couple of other things have multipliers so those multipliers are being multiplied against something and they're being multiplied against BC LK so you have a 100 BC LK and a 40 multiplier then you have 4000 megahertz frequency or 4 gigahertz so that's the basics it is what the multiplier is multiplied against and then the product is your frequency and as for what it is BC LK basically replaced the frontside bus on Intel so FSB is is gone and as been replaced with BC okay be CLK links a lot of things so if you change your BC LK speeds this is why we would recommend doing it last typically because you're pretty likely to introduce more instability just because b CL k impacts the PCIe interface speed it impacts the memory speed so if you change BC LK to something like 101 and you have memory at 3,000 3,000 megahertz when it's at 100 you increase it to 101 your memory will increase a little bit not a whole lot you're typically talking like 50 megahertz or something like that depends on what your memory multiplier is might be like 20 666 or something like that so twenty six point six six so those are some ways B CLK impacts things I it's basically i/o pulses per second for stuff like IO devices that are attached via as PCIe again as an example and then sometimes BC LK is useful because you can get half steps with the frequencies so if you're stable at 5150 but not fifty two hundred megahertz then BCL K will let you get 5150 just you might have to also decrease the memory frequency if it gets kind of tricky because if the memory is not a good bin and the CPU needs another 50 megahertz or something then you're starting to suddenly put more strain on the memory as well so it's not a good bin memory then now you have to step down your memory clock to accommodate the extra whatever megahertz increase from the BCL K multiplied by the memory multiplier and suddenly you're doing a whole lot more tuning to just try and get 50 mega it's in a lot of cases now there are instances where you get far more than that but for a lot of people I think that's how BC LK is typically used and it depends on the board partly and depends on everything else but the board especially depends on how far you can push BC okay a lot of the time 101 is pretty achievable you start pushing like 103 104 is suddenly it's not really that doable with a lot of tweaking and/or with a particular set of hardware that just happens to work well with it and that's because again you have stuff like the PCIe bus falling off or memory having issues with stability so it might not even be a CPU issue anymore so BC LK replaces FSB and is basically a it's the the clock that all the multipliers get multiplied against and you can get a bit more frequency out of it as far as voltage sometimes we've found that increasing BC LK and decreasing the multiplier allows us to keep a lower voltage than just going straight multiplier and sometimes just going straight multiplier doesn't even work at a certain point and you have to do VC LK so the answer is yes sometimes you can keep the same voltage and drop your multiplier but end up with a slightly higher clock just because of how the math works out next one NNN SSS says how exactly do video card driver updates improve performance on games over time especially considering the fact that hardware stays exactly the same what kind of instructions are added or amended to peace FPS or improve stability so this is a great question I have an answer on this but I'm going to expand on it so the reason I bring it up here is just to let you know like we talked about with the 10 nanometer question that videos done should be live by the time this one's live we're gonna push this off to an expert actually driver developers at Nvidia and hopefully I get AMD 2 comments as well and if we can then we can get people who actually do driver development or manage it in the very least and and talk about what they do and probably have medium depth I don't think they're gonna go too deep on it but they'll give us they'll give you more than I can from a technical perspective so I want to push that question off the experts hopefully we get an answer for the next either if not next weeks then maybe the one after that it just depends on timing for everybody next one Swift says do your motherboards that matter anymore back in the day if you had a budget motherboard and an expensive one your performance would differ but is that the same with today's motherboards example budget be through 50 board vs. high-end X 370 board so yes they matter a lot there's the issue of the vrm it was the issue of overclocking at all on Intel so Intel locks down their non Z board so if you're playing on overclocking then obviously you just can't so that's that's pretty easily answered there if we assume you're not overclocking or you're using AMD where you can overclock on beat 350 and X 370 you have a vrm concern so there's an issue of the motherboard vendor cheap out on the VRM on their lower end board and so that may constrain you at some point with your overclock so there's a huge potential for difference let's say you have a really good bin CPU on a good board versus a super cheap board you might lose a hundred megahertz 200 megahertz off your achievable maximum clock depending on how good the motherboards BIOS is but how could the vrm is the BIOS has probably the biggest impact on everything these days so a bad BIOS will limit you severely if it's really truly bad for the most part the kind of average to above-average and up boards for I think the average beginner overclocker it's not gonna make a huge difference but you'll start seeing differences if there's no vrm cooling there's a bad v around the heatsink and you're using a case where you don't have a lot of airflow near the v RM then you start having issues with potentially v RM thermal throttling we've demonstrated it in the past on an asus board that had no v RM heat sinks you run into like SPID issues with intel platform s PID on Intel platform starts coming into play where you have a protocol between the CPU and the v RM components how they talk to each other so MOSFET talking to a CPU says it's getting too hot I got a down clock and then you can get down clock in there so here's another thing there's more to this than just FPS a lot of people think of performance as strictly one number which is frames second that's a little flawed because there are other aspects of performance like power consumption so a motherboard for actually he plays with power consumption directly so here's an example that when we reviewed one of gigabytes a z2 seventy boards I think when they first came out we ended up actually really liking the particular board later the gaming seventy two seventy board but when it came out it had some issues where the auto v core was just crazy high like it was R was one point three or something like that can't remember exactly we had a video in an article on it but it was something like one point three volts to sustain more or less stock and in that scenario your if your stock you're still going to get the same frame rate for the most part as the MSI immediate equivalent like getting a pro carbon or something like that you're gonna get the same frame rate more or less as the Asus boards but the difference now is you're chewing through way more power your temperatures higher so suddenly you have to run your fans at a higher speed make sure system louder it means that you have to and more power there to means you might have to upgrade your cooler and in general just kind of wasteful so and also you'll feel like you have less overclocking Headroom if you're not particularly skilled with overclocking to spot that Auto V core is blasting through so much power so that was solved with a BIOS update to be clear on gigabytes on but this still happens regularly with motherboards all the time and there's more to performance than FPS you could be wasting a lot of power you could be running hotter than anywhere you're close to reality should be for the CPU so seventy seven hundred K in that instance was something like 90 plus degree Celsius or thereabouts with the stock settings with Auto V core on that board whereas any other board that used a same V core like one point two to one point two seven or something like that those at one point actually one point one eight to one point two is about what we found others were running at four first stock those would be running significantly cooler so that's a big consideration to so you have BIOS you have things like Auto V core you have other auto voltages you have limitations or actually the opposite you have sort of hidden I don't know benefits of MCE which isn't really beneficial but if a vendor decided to turn MCE on by default it would look like the board's performed better than it does it's a trick that motherboard vendors play to try and look different from each other like superior I'm not presently aware of any better that I've worked with lately that are shipping with MCE enabled by default seems like they've all turned that off but I haven't worked with every board I'm sure there's one out there somewhere but those are some of the things to consider pyramid quality is a big one to really sum this up though the difference is motherboards it is something you should care about if you're not going to overclock in a somewhat serious fashion then you don't need to stress too much about all the small details because ultimately there are a lot of small details and unless you're really really serious about overclocking getting like an X 299 dark as great as it is might not be something you can appreciate unless you're really using it and especially on like the memory front where it's a really strong motherboard so there are absolutely differences in boards whether or not you'll ever see those differences depends kind of on how observant you are of things like power thermals overclocking and things like that there are instances where boards out of box will appear faster or slower than the other a lot of the time it's because of either something like MCE or they're kind of cheating or it's because of something like the BC LK which we talked about earlier in this video so BC LK on some boards just as an FYI you'll see it bounce between like 98.5 and 101 maybe 101.5 depending on which motherboard you're looking at so it doesn't hold steady at 100 you will have performance fluctuation if you ever see like a 5 percent change between two boards and it's not margin of error that's probably what it was one probably went down to 99.5 and the other one probably held a hundred so there are lots of ways motherboards differentiate themselves and yes they do matter next one I'm an e 99 said in your videos you have suggested better tester for going the application of silicon between IHS and substrate after deleting a CPU one of the points made with other deleting videos where so it's it's silly so cone with an e at the end not silicon where silicon is applied is to leave a gap to allow for hot gases to escape is that a non issues and not applying the silicon means completely closed space yeah it's not really issue your biggest concern is not having an air gap because an air gap will create these hotspots between the die and the IHS underside and air is less than 1 watt per meter Kelvin at 25 °c and coppers 400 so having any kind of hot spot between the die and the IHS is undesirable even if there are other theoretical benefits like allowing venting of hot air in reality what matters most is having contact and adding silicone adhesive increases the risk of a gap significantly and also increases the the chance that it doesn't settle quite right a lot of the time when I delete it and leave the lid loose 100 percent of the time these days it's fine I can use it straight away when I deal with it and try to reseal it like we do for other use here whereas it normally takes me two tries with a lot of testing to really get it the way I like it and you're always going to be a bit hotter than if you don't reseal it next one is from we have two left Galia says will there ever be a CPU cooler that comes in one piece with the IHS so all the ladies to ask bien you basically said that the fewer layers there are between the cooler and IHS the better so why not make a solution that removes all the layers someone could delete a CPU and buy a custom cooler for an already deleted CPU and just put it on top of the CPU instead the regular IHS and cooler so you it's if you're not aware of it there is actually something called direct eye cooling and it's not that common so not a lot of people use it it's more common with the high-end platforms like X 299 and their Bower makes a direct eye cooling kit for example it's it is a a low volume enthusiast part so now a lot of people talk about this direct eye cooling is basically what you're asking about except instead of attaching the IHS to a cooler it's just removing the eye adjust from the scenario completely and attaching the die to the cooler via your normal compound normally thermal paste you could use liquid metal but at that point it's not even necessary because direct eye contact matters more than anything else so direct die is what you're talking about and it requires a mod to the sockets pretty straightforward you remove the socket and then put a new one on and as long as the clearance is the tolerance is safe from a good kit you're not going to crack the dye the reason IHS there is there is to protect the dye from users installing it cracking the dye stuff like that so what you're talking out exists look up direct dye cool and see if a kid exists for the socket you're using and maybe give it a shot just be aware there's there's a bit of risk follow the instructions very carefully if it's a good kit then you'll be fine and I that more or less answers that one last one is TK 949 who said loved the video about Andrew Hans audio room that's the EVGA CEO we did a tour of his audio room if you are allowed to share or elaborate how was that video crafted where did the opportunity come from and what made you decide to do it anything else you might be able to share so I think the as far as how the video was was crafted it was basically this was I think at the end of Computex it was in his one of his apartments or condos in Taipei and it's a we basically just talked to him at the EVGA suite I had heard about the audio room before and we thought that would be a really cool video opportunity so I asked him if we could basically invited ourselves over and asked if we could check it out and he was happy to show it cuz I don't think anyone's done a video on that room before I'm not an audio expert but Andrew Hannes sure knew a lot about what he bought so we were able to just talk with him and learn about everything in the room and piece it together based on what we could what we could learn from him about the equipment he bought it's really impressive it's as again someone who's not an audiophile it certainly seems like something that everyone should listen to if you get the chance because basically it was a super directional sound I was expecting not that but it's very specific to where you are in the room so you kind of do like five rows back in the middle positioning and then you can hear the sound sort of come out in like layers because it is a layered horn so you've got the tweeter inside of the horn the horn with the I mean it goes all the way back I think 3.1 meters and a big coil as the driver at the end of it and then there's the subwoofer so it's very interesting as as where did the opportunity come from again we heard about it from people in the industry who'd listen to the room one of EVGA s employees had mentioned it to us and so we wanted to record it because it's its old very cool technology that works well and you don't find a lot of that especially in as good shape as it was there so very interesting tour to do anything else I can share on it I guess he's got a he had a couple of books so he had like a limited around 1,000 unit book that was on all the old western electric gear so I had stuff dating backs like the early 1800s pretty cool stuff and then other than that I think pretty much what you saw in the video is mostly what we had to say so yeah thank you for asking that was a very interesting tour and he seemed like he had done a whole lot of research on the audio equipment so oh yeah we also got this this plaque from from Andrew Hahn so this I think came with one of his western electric audio pieces that he purchased and I think when I researched it I'm pretty sure this is there this was their logo up until like the 60s I think it was the 30s until the 60s or something like that so it was made sometime in that time line and given on based on how it was made it looks like that's about right for the era so yeah pretty cool stuff you haven't seen that video check it out we had someone email me and they were mad about my phrasing for a few things like I guess I referred to the the the needle on the record player slightly incorrectly so if that bothers you then probably don't watch it but otherwise it's really cool stuff and as always that leave your questions in the comment section below if you have questions for next time thank you for watching go to stored on cameras nexus net to pick up at one of our shirts mod matt post or anything else we've restocked a lot of things lately we're go to patreon.com/scishow and Razak just to get the bonus episode we'll be filming in the new office soon so definitely make sure you subscribe for that I'll see you all next time
