hey everyone welcome to another episode of ask Gianna I think we're on episode 41 as always if you have questions leave them in the comment section below I've given up on a foot down both I'm just reading through all of them again because YouTube doesn't work properly but before getting to that this content is brought to you by catalyst gaining immense and energy boost designed for gamers to

business there's a different shirt I actually have many shirts you might not know that I think there are two instances ever we're in a gamers Nexus video I've not had a GN shirt on one was an interview with Kent Smith three years ago in California about SSDs and preconditioning and then and write amplification factor the other one was with Jim Vincent recently when we were at CES and did a look at his poor man's laptop setup which was actually a really fun video speaking of CES there the first question I should mention by the way we're playing around with certain designs so this might be something or something similar to it anyway that we end up using as a reward for patreon backers so folks who contribute to patreon in the future will probably add more shirts than the main one that I normally wear just have to work out which material to use and stuff like that this is a much nicer shirt material so CES questions the one I wanted to get to John Adamson asked what was the mic that Steve used during CES and I actually saw several people ask this while we were at the show in comments for multiple videos so this is not a secret I've talked about this mic before I've had it for several years now this was the first piece of audio equipment that I bought when I was still setting up all the film and audio and everything myself so this is at least three years old now my before I think it might be four and there's a son Heiser md 46 when I got it cost me $200 we've improved it since then by adding a wireless transmitter for our fairly expensive Sennheiser g3 wireless transmitters and receivers but it's been the same mic the transmission has changed the mic itself is what you'd call a reporter mic or a stick mic I bought it originally because I was looking at I wanted to know what was a good reporter Mike we could use with decent audio quality for a loud environment so actually what I did was at the time I went and I looked at photos of presidential conferences and looked at the microphones they used for when the president spoke because I figured well that should probably be pretty damn good because it's an important thing and actually surprisingly several news outlets used this one and when I looked at the price was 200 bucks that was an easy buy because for audio equipment that's really not bad and it's obviously lasted a long time and it sounds pretty good which we're recording both tracks right now so this is how it would be talking at CES or something like that and you can hear the audio difference between the lab and the reporter Mike when I switch between them and Andrew will of course unfortunately have to silence or whatever to work with the tracks but that's the idea so this has really good quality when you're in a loud environment which we're obviously not in right now and on a convention floor with ten thousand people around us it isolates pretty damn well every pax our coverage from the floor there it's really noisy there we basically have to yell at each other to hear each other with the interview subject but the mic makes it so it all picks up really well without any of the background noise being making everything else inaudible so that's the mic the receiver transmitter set up is the g3 sort of bundle I think I paid $600 per unit for those and the transmitter was something like 150 and then it's all plugged into a recording device that we've also shown in the past and that was another four hundred dollars or something like that so it does get pretty expensive pretty fast but that's the basic setup fun fact about this microphone it is now famous because Linus from - tech tips came over to borrow it during an AMD video we were in the AMD suite at the same time at CES and we finished shooting our video he came over and said we are our transaction no I write but you have the receipt as well what he was like no I just just all of it I'm sorry I let him borrow all of it because they had think they left one of their things in the room so that Mike is now famous if you look at his video with Roger Kaduri about Vega you'll see that blue fuzzy faint on the mic and now you know you know the secret next question oh by the way I'll just point out of course we work with Amazon Newegg like most other outlets do if you do like that mic and you want to buy it you can hit the link in the description below I'm a big fan of the mic I really don't really sort of talk about things like that but it's audio equipment it's not part of our core coverage so that is what I like next question was from Nome Fick she o Fichte Co no I'm Fichte CEO says SG and hey Steve love the work never leave us please so how does RAM frequency affect CPU overclocking I read that having a more direct multiplier say 10 X 4 20 66 2666 instead of 2800 for instance could result in an easier time getting those last few megahertz out of the CPU due to more stability is that so with XMP how so why you know the drill so memory overclocking is not somewhere I'm an expert in that is of course plenty of places that's true because computers are hard and there's a lot of parts and there's a lot to know so I did want to answer the question though because I like the question and wanted to learn more about myself I sent the question over to build Zoid who he runs actually hard core overclocking and we've recruited him several times for videos so he knows what he's talking about builds I'd said first of all the question the asker said something about buying the Patriot kit and feeling some regret and maybe wanting a g.skill kit instead so I passed that along to builds right as well he said there with those specific kits it doesn't really matter but some Ram multipliers are just completely broken on some platforms like x99 lots of boards can't do X 28 or x 28 on the RAM so you're stuck with 2666 or 3000 it's pretty much tied to the cpu memory controller the BIOS and the board layout I asked him about z170 and C 270 and build Zoid said on z170 some of the really high multipliers are also broken on z87 and z97 if you want to go over 3000 megahertz you would generally run a high B CLK with a lower multiplier rather than trying to run 30x or higher multipliers and he had a bit more two more blocks of text to go through that are all pretty interesting depending on the platform B CLK affects literally everything Hansie 170 the BC LK for the chipset is separated from the CPU RAM and uncor base clock but in the past base clock affected everything from SATA ports to the CPU core clock and actually you can see that by just adjusting it yourself without even applying it and you'll see some of the other numbers increasing in BIOS to the nearby us and motherboard he also said also going back to the RAM it won't affect your core clock till you start pushing some really high speeds on Z 1 so on z170 that would be 38 66 and up and then further said on X 99 it doesn't do anything to core clock because the I think is talking about base clock doesn't do anything to core clock because the memory controller completely gives up before alia completely gives up before you get anywhere near speeds that affect the core so that's a problem with again X 99 we've seen that issue to where you just can't you can't push the memory that high with really specific multipliers and that's exactly what he's talking about here some multipliers just straight don't work further set z97 z87 past 24 hundred megahertz some CPUs start having issues on am3+ 21 33 can be problematic as for his actual Ram choices I would probably go for the C 1526 86 G skill kit since G skill generally has better mobile compatibility and if he decides to OC the RAM will probably go higher so there's the answer to that question I think that's kind of the quick version of it but you get the idea next question is from land strike gaming who says Steven having issues with the fans on the XFX 488 gigabytes gt-r 1338 megahertz and wot man I set the fans to turn on at 300 megahertz acoustic level and set the thermal limits at 55 C and 40 C targets the fans are not turning on to cool the card when idle my PC repeatedly displaying a heat warning at 55 C I try to adjust the settings in watt man and the fans just are not responding so I don't have that exact card but if if you are not aware most modern GPUs and the and Nvidia like depending on the AIB partner more than the GPU vendor but the AIB partner for most modern GPUs will allow for a zero rpm idle the ideas no noise and they let the temperature go up a bit with some cards like some MSI ones I've tested an EVGA you can get as high as 65 Celsius before they turn on and sometimes depending on the again the partner there might not be a bypass for that it might just be a hard 65 C it turns on or 55 or whatever the number may be and your only alternative to toggle it completely off and lose that quiet functionality altogether so I'm not sure if that's the exact issue you're talking about I think I understand and if I do that is all it is it's not a big deal the fans just don't spin up if it's under low load the card is fine it's not being actively hurt by this temperature of whatever maybe is 65 70 even it is completely fine it's just trying to run without any noise next question is from neo voodoo tech who says question for next week Steve what do you think about using a small fan or heatsink to cool routers and modems I've recently been experimenting and found some positive results for cooling your network hardware including lower pain and latency and slightly faster sustained downloads and transfers this is actually a really cool idea it's not something I've done but I have read about it in the past and so depending on your if you've got a switch especially like we use a gigabit switch for internal transfer when that starts really getting hammered by multiple computers it does get pretty hot and the internal cooling solution is not great so in that situation adding an aftermarket cooler even to our internal it would probably be pretty helpful because thermals ruin everything once you get higher heat because it's been abused for a longer period of time and it doesn't get a chance to cool down that's true with pretty much any electronic you will have performance degradation does it doesn't matter what it is and that's either because they have restrictions built in there to protect it and make sure it's not running too hard of a clock rate or whatever when it's under load or it's just because there's degradation because it's becoming unstable or volatile or whatever and then also of course it's not great for electronics on a small box with poor ventilation and a high amount of utilization to just sit there and burn themselves through years and years because eventually you're gonna have issues where it's just hot all the time because it's burned through the thermal paste or the coin components the passive components have shifted just because of heat expansion and contraction constantly I would say it's an interesting idea I haven't tried it but I kind of want to now I will say for routers I haven't had as much well I should say for for modems which isn't really what they are anywhere but you know what I'm talking about the box from ISP I haven't had as much of an issue but maybe if we started pushing the higher one gigabit per second data rates once that's available maybe that would actually a problem I don't know but with my current internet it's just not for the switch no absolutely that wouldn't be a bad thing to do because you would be able to maintain like you're saying the higher performance because it's not gonna have the down clock or throttle itself in order to keep up and keep temperatures down that's especially true if you have it in a hot environment or high ambient next question charlie lee says why do we need i HS integrated heat spreader isn't putting a heat sink dragging on to the CPU more efficient yes absolutely it is more efficient if you have no I HS that means basically anyone doesn't know it's a substrate that's the green bit and then there's a dye and then over that is the IHS for basically a piece of metal that helps conduct the in theory conduct the heat from the dye spread it a bit and then from there the CPU heatsink should be conducting that and we talk about that by the way in our TL DR video on CPU heat sinks there's an animation everything is pretty cool check that out but that's how it works so it would certainly be more efficient if you had direct contact and that's what happens with GPUs if you ever opened a GPU or a video card I should say you'll see that once you pull out those four screws for the heatsink and pull the heatsink off it's just a straight die there's no IHS it is far more efficient to have direct contact you don't have another interface and between them and it's not just one interface by the way for an IHS on a CPU the die doesn't directly talk doesn't directly communicate its heat to the IHS it's got to be something in between it's not a perfect match and the same is true from the IHS to the heatsink it's got to have an interface between that interface is normally a thermal paste sometimes it's liquid metal found if you view if you've deleted it or not and we do by the way I have a d-league kit and I will be playing around at that pretty soon but that's the idea so if you have a die and then thermal compound which the current generation of KB Lake 7700 K thermal compound does not look at all like it's consistent we're still investigating that but thermal compound IHS thermal compound by the user or Tim and then your cold plate that's a lot of things to go through to get to the cold plate which is your highest watts per meter Kelvin conductivity so you don't want all those interfaces there so why not just sell a CPU with no IHS if Intel knows people are gonna put a heatsink on it because of course why not sell it that way the reason is strength primarily because if you have if you've ever maybe not deleted but if you go look up YouTube videos of people trying to deal with CPUs I'm sure someone's cracked either the entire thing or the die because those silicon dies are really weak they can crack on GPUs and on CPUs very easily if you're not careful either from the D LED process itself or from applying a cooler no IHS does a pretty good job of protecting that thing and strengthening it so when you go torque down the four screws for the cooler on the motherboard it's not going to crack anything in theory but the problem a lot of folks will either use sort of guerrilla force when they tighten their things down until they can't physically turn the driver anymore even though you only need one or two threads really locked to have strength and if they do that then it's just it's not gonna be good when there's no IHS Mike something will probably crack no that's gonna be pens if it's something like an AMD CPU and you've got no other weak point although that's not really something you see a lot or more likely it'll be the die if it's deleted so that's why the IHS is on there it does theoretically conduct heat but I would not say it helps conduct heat in so far as improving the thermal transfer properties it has improved only only as far as I don't know it's adding more interface is always bad that's the short of it the next question Mike or Mikkel rather Bledsoe says question for Steve say I have my wireless USB dongle plugged into the USB 3 header on top my computer but the speeds aren't consistent I've moved everything away from it have it top and Center yet speeds are still fluctuating a lot would be better to plug it back into my motherboard I've had this problem a lot we use wireless transmitters or just say the wireless dongle is just for use in other rooms where it's not hardwired although I do prefer hardwire but the the problem is either while one USB three drivers for those controllers on the boards depending what motherboard you have they aren't always that consistent connection drops all the time had the problem on most systems I've built in the last few years at some point you lose connection and that's because the controller and the driver just not being stable it could also be the key itself if it's trying to it was just not a high quality one there's plenty of $20 angles out there I wouldn't recommend but I've never had a problem plugging my wireless receivers transmitters into the back of the computer straight into the motherboard that'll be handled more directly without any external any third-party controller now with Intel and their modern chipsets is a bit different but with the older Andy stuff or stuff before usb3 was on board natively through the chipset that was absolutely a problem but yeah I tried putting it in the motherboard and then wiped the drivers as well and see if that helps next question Daniel Otis says could you tell how much power can the motherboard via Ram supplies of the CPU by a number of phases for example X amount of watts per phase 3 phase v RM is barely enough for a 95 watt TDP CPU but 5 is good enough for even a modest overclock it depends on the components used so that's what builds oh it does for this I included this question because we just posted a video on the gigabyte gaming 7v RM it's an analysis that he did on the FETs everything in there and voltage controllers things like that and you can learn more about the sort of the what the phases can handle and how many ABS can go through it and all that stuff that's all in that video the short answer is no there's no hard and fast x phases equals y amperage or watts or whatever is just it depends on the quality of component used finally this one I really only put in there to make a note oh well I'm not gonna say that name so nevermind is worse than I thought you can go look at the previous video though and I'm sure you'll see at least one dumb comment but thank you for watching as always patreon link in the post roll video leave questions below to be included in the next video trying to do these weekly as we've been doing for a while now we've got a few shows coming up but the next big one is not until Computex before that is PAX East though but we'll be at home base doing all the testing until that time so again patreon link post roll video these tight shirts might be going out in the future like for more content subscribe all that stuff see you all next time
