everyone welcome to another ask gene episode I think this is our last one we're shooting here we're in Tokyo right now we were in Taiwan previously and we have a rapid-fire Computex ask Jia and that'll go up shortly we also have a patreon Bachrach Deanna's always on patreon.com slash gamers next is if you want access to that content before that this video is brought to you by us and the gamers Nexus anti-static mod map the GaN anti-static mana is a four foot by two foot surface 2 millimeters thick of high-quality industrial grade anti-static material and it includes a common ground point for earth a grounding wrist strap and it has on its electrical wiring diagrams that may prove useful a GPU silhouette and grid for your teardown efforts and other useful items go to store documents Nexus dotnet to pick up a GN mod mat today so for this week we have a couple good questions one of them the first one I'm about to read some answers from builds IDE for because I wanted to make sure I really got a good answer on it referenced a minutes from pretty good to hear ketchup is his name who asks some power supply manufacturers including EVGA have in their product descriptions and advertising for helping you achieve higher overclocks what do you say that this is fundamentally true so I did I spoke with builds right about this I think to an extent it can be true for sure it depends on kind of what you're talking out for overclocking though certainly a really cheap bad power supplies growing impact just about everything but once you get into decent and above how much does it really matter so osep limits are something to pay attention to at the very top level if you have for example multi rail without a single rail toggle or function that can be a limiter where we've run into that in the past with some of our power supplies where they're multi rail and they don't allow single rail toggling and you can't change our CP so it was something like a 79 80 XC it's not hard to trip OCP at like 50 amps or something like that so that can be a limit but to get to the more serious part of the answer it kind of comes down to potentially impacting how much voltage you have to apply to the core or whatever you're overclocking in order to maintain a stable overclock which can impact thermals and the current and stuff like that so for builds ODEs answer what he said was power supply output ripple is relative to power supply output power if you have a power supply that has terrible ripple at full power and you're see polls the power supply rated max output you're gonna have worse voltage regulation on the output of the vrm you know it's also on video cards have current based power limits so if you run Pascal on a power supply that slides from twelve point three to eleven point six volts you will boost slightly lower than on a twelve volt power supply or a twelve point three to twelve volt power supply and power being a he said to function this overclocking for Pascal specifically is a function that's slightly limited by current depending on what you're working with so and with wattage being by the way a multiplication and product of current and voltage so bill toy continues and says if a power supply has bad transient response it will make the output of the vrm worse and notice that with 79-80 axes on liquid nitrogen the main concern is having the power supply not trip OCT when you go from idle to full load the vrm needs to quickly pull itself from pushing say two point three volts 40 amps to two point three volts 400 amps and that causes a massive current spike further continues the vrm may well just turn on all of the high side FETs at the same time to try and maintain the output voltage because vrm output voltage is tied to current flow through the inductors and at idle the inductors have very little current flowing through them they will drop voltage in order to maintain the same level of current flow again they're a function of the two when we talk about power and in order to increase the current flow through the inductors you need to apply 12 volt on the phase side of them and then if during one PWM cycle you have 30 millivolts or more than on the next at random for ripple it just makes the output of the BRM that much noisier so that's most of stuff to consider that's from Build Zoid if you don't know who he is good actually hardcore overclocking on YouTube that's his channel he does work for us as well here on gamers Nexus x1 Jeff M says are you looking at getting any fan text cases for testing this year in my opinion the evolved X seems to be a solid contender for the best high-end case this year and I'd love to see it put through its paces with your thermal sizing answer this in the rapid-fire copy text video where we talked about fan tax and three questions and to just recap it again fan tax was unable to accommodate a meeting after multiple attempts at Computex so we will instead be purchasing the the Senate's available to give it a look through our testing as usual because I didn't get to see it in person so well look at it that's fine not everyone can accommodate a meeting that trade shows there they're very busy with a lot of people and they have to meet more than just media they're meeting all of their channel partners and stuff like that as well and no big deal I suppose that is we got turned away several times so whatever we'll we'll figure it out well by one next question is from a Tallis recreational nooks who has the best name says why and power are some RAM gives off optimized for Intel and some for AMD how would this bidding process work it's actually not a bidding process so much as it is the motherboard support so with x4 70 a lot of the updates were just improvements to memory profiles over X 370 with chipset updates being functionally zero and it comes down not to bidding of the memory dies or the quality of the ICS but rather to the the validation of those chips those dies on the different AMD boards and it just so happens that samsung be thy works very well with AMD in an easier fashion you can get the other stuff to still work it's just B dies more or less plug and play as long as it's been validated on the board so it comes down to memory is very manual the vendors have to test it and that's why we recommend especially with rise and when you buy a motherboard go to the supporter memory kit and make sure or the list rather and make sure that the kit you want is on that list that they validated it it actually matters it's not just plug and play sure that'll work but if you really want performance that's what you have to do because there is testing involved and they basically the vendors go through and they manually tune all of those sub timings that they can anyway so when you plug the kid in it's not just picking timings at random which is what will happen if they're not manually tuned on the board it'll just it'll keep retrying failing to boot retry and that's called memory training so the fewer timings that are needed in need of manual tuning by you the better and that's going to come down to the motherboard vendors more than the memory chip makers although the memory chip makers work with the vendors to make sure that it's all on the up-and-up next one is from GGC HB who says Steve would overclock and be easy in space if the PCB were outside the ship for spaces negative 273 Celsius or would lack of air prevent conduction of thermal energy away from the core so this is a really interesting question I saw some comments talking about how cold space is or isn't and whether or not it would actually be negative 273 I don't know what what temperature of different parts of space are but let's just kind of assume that you are actually at basically absolute zero or very very cold temperatures like you're suggesting a couple of problems here one of them is cold bugs so actually being too cold can be a problem and with the scenario you're talking about because there's no air there's no air flow there is going to be a problem where dissipation is not really possible you're actually gonna do better with radiation and heat than with normal conduction and dissipation because that's that's the most you can do at a temperature like say that on a three Kelvin or something like that or 5 Kelvin whatever it's basically sub 10 K radiations what you're dealing with for the most part rather than airflow because there is none so that's going to limit things but before that's a problem because that would be a heat problem not a cold problem because you can't get rid of the heat fast enough before getting rid of heat is a problem you have to turn the system on and cold bugs are free let's take Titan V for example the Titan V has a lot of trouble below 10 degrees negative 10 that is Celsius for doing much of anything HBM 2 has a whole lot of problems with negative temperatures Celsius where it can just become unstable has cold bugs doesn't boot we saw this with Katyn pens Robo clock or where if 10 his his man on the keyboard basically setting the target temperature if he set the temperature to low before the system turned on it would just not boot and that's problem that's a cold bug so that's why they have things like socket heaters on the back as well sometimes the heaters are to prevent things like condensation but other times it's actually to prevent a cold bug where the silicon just bugs out just stops working below a certain temperature and so that's that's probably a bigger problem you won't be able to even turn the system on but if you can then getting rid of the heats going to be a big challenge as well because there's no just dissipation via air flow and conduction it's gonna be relying on radiation next question is from actually the same person I think GGC hbu says is there a good alternative to liquid metal for deleting long term most people recommend replacing alum every nine months I'm too lazy is there a high qualit so speaking from personal experience now we've had a high-end CPU running liquid metal for several actually a year at this point our slightly more than a year and haven't had to replace it thrown performance is more or less the same as it has always been and that's conduct or not so speaking with thermal grizzly they are a biased source keep that in mind they have tested up to two years as far as I'm aware and say that two years is fine for conduct or not so I haven't tested beyond the year or so that we've done the system we're running for this long-term endurance test but it's still doing just fine so I don't think I think with a quality liquid metal you don't have to replace it quite as much as for Tim's yeah I just you want something that is not going to cure in the same way that stuff like the stock case that compound it's pretty good but it cures and becomes hardened after a while and that's a bad thing to put under the die so it's something like cryo not where it doesn't cure and there are other ones gelid extreme stuff like that would be fine to just if it's conductive be very careful and make sure you mask any SMD so you don't short them but anything that doesn't cure quickly or at all would be ideal and actually Intel stock pastes if you want lazy is a good route to it's just not particularly conductive but it does last a long time so that's the easiest thing to do of course if you want to deal it though get something that doesn't care too much and has a high thermal conductivity next one is from wormwood who says there's a quick one any idea when an 80 86 K review will hit the answer is probably never because it's an 8700 K that's been overclocked and it's priced too high and it's kind of a dumb thing to buy so next next question from silk monkey who says with the trade shows combi ducks III etc going on I was wondering what was the best gimmick you saw at a booth at a show and what was the weirdest the best I'll say gimmick was probably dare Bowers cooler and I the only reason I'd even apply the word gimmick to it as it's a functional thing it does cool the product is his face change cooler so it's not 3m Novik but it's another fluid so it does actually cool the product it's functional but it's not going to be a standard solution you would put into your system you typically go with the CLC or an air cooler so we really like what he's done with the phase shift cooler it's just that it's something that gets a lot of attention and it'll be low product volume very interesting product might be good we haven't tested it but the end of the day it's something that he's done to get some some marketing buzz as like a halo product and we've looked forward to it we gave an award all that stuff but yes I would ultimately say that it is somewhat of a gimmick because is it necessary no of course not you could use propylene glycol and distilled water but it's cool this he's only different nonetheless the weirdest was probably a she's a separate separating MITx case because it was very odd implementation it separates to allow airflow but there's no ventilation on either side of the separating joints so it actually doesn't allow air flow but that's their plan I guess after some revisions last two inks says where did you or do you learn about the business side of what you do here on the channel marketing how to sell ads best way to approach companies and so on behind the scenes to run the channel Chen the answer is doing it for like 10 years basically on the website side doing YouTube bit later and kind of trying things until they worked is really the answer that's the only way to do it I think and being in front of people at trade shows as much as possible next question el Pye says how do you feel after heat torturing the poor HUD Matt so it was I mean it was pretty cool it was cool to see how well it held up to things like soldering and the heat gun for tube bending stuff like that holds up super well because it's not a soldering mat and as long as you're okay with the a singe mark it was really quite good with soldering so silicon Matt would be the best if you want something that's like really really resistant to soldering irons at a high temperature but we were very happy with the results of our my Matt even though it's not marketed as a soldering Matt and it did very well with to bending temperatures as well so as far as how I feel about it I'd say it was justified and we can still use it in our lab even though it's it's a bit scarred at this point so as always if you're interested in one of those go to store tech here in a second yet to pick up a mod Matt they are on the way now so you can backorder it make sure you get one otherwise patreon.com/scishow and exits to watch our bonus episode subscribe for more thank you for watching I'll see you all next time
