hey Ranjit ICI 2018 by now by the time the video goes up probably over but I wanted to show off some high-end compute stuff that we don't normally talk about because there's actually some pretty cool cooling solutions in here from ek water blocks and there's of course other high-end things that are interesting but this is the old one now I guess DG acts Station one they have some DG x twos out here as well that we'll look at briefly although we have another video on that either way though what I mainly wanted to point out was the ek cooling solution just because it's not like something we typically see in the enthusiast space before that this video is brought to you by EVGA and the X 299 dark motherboard for the Intel high-end desktop CPUs the X 299 dark is one of the only motherboards on the market with proper vrm cooling we've tested this and found significant performance increase over those without active cooling on the BRM this board was used in our recent attempt to set a top 10 record in fire strike and you can learn more about the x9 and dark at the link in the description below for the basics this system is basically assembled chip sold by Nvidia and its partners like PNY for example but for the cards in it it's got 4 Tesla V 100's so it is obviously a high-end workstation system or scientific compute system and the 4v1 hundreds are connected into an open-loop cooling solution that's graphics only so the CPU is cooled independently by a closed loop as shown over here that's either one of eks closed-loop or an ASA tech six gen I'm not positive which either way that's we can kind of ignore the closed loop the open loop is where it gets interesting because there is a special block in the front up here towards the front of the system where there are two pairs of pipes for each cards they've got in and out obviously and those are connect to be a quick release which makes them a little bit easier to maintain in the field if something were to happen if one failed or if you had some kind of issue with the cooling solution so quick release setup in the front for the Block in and out for each one those feed into the cards obviously and then that gets piped up here to be a just the block to a three sixty millimeter radiator in the top so the 360 right on top has three EK Vardar fans I believe well I'm positive and there are three borrowed ARS 120s each obviously I'm not sure how fat the radiator is because I don't know how or if we're allowed to take this top part off it's probably online somewhere someone's torn it down by now but the top part as I understand it is not officially part of the cooling solution but I don't know depending on which marketing materials you believe this sort of fake fabric up here is a metal it might be an aluminum for example and I guess theoretically that breathe is a little bit it's kind of mesh like you could get air through there if you really wanted to theoretically you could connect to it conductive Li and move heat through it I don't think that's how it's being used but I'm not sure there's the first time I've seen one in person either way though cool incision from ek is pretty neat just cuz it's not like the solutions we see from them in our line of work and if you're curious about the rest of specs 256 gigabytes of system memory has a twenty core CPU in it one of the Zeon's I think it's a twenty six ninety eight twenty nine sixty eight version four and I think that pretty much wraps up the dgx station so now we can move on to some of the newer stuff on the other side of the booth over here okay so now we've returned to the DG x2 this is something we looked at a couple of days ago after Jensen's keynote we showed the basics of it externally but now we've got one that's actually opened up a bit more for us so we can get a closer look at how things are working first of all I had a couple of questions answered from the first coverage of the DJ x2 if you remember I showed some of the cooling solution on it there are copper blocks along the front in front of the aluminum fence tax and those copper blocks which are located up here they're actually sitting on top of env switches so that's what those are for I was curious earlier if got the answer any switches for those and then these are just on top of the GPUs as noted previously the Nvidia embellishments here on the top primarily for looks but underneath that you've got a standard aluminum fin stack standard heatsink application couple of screws some thermal paste nothing unfamiliar to you all ask for the copper block though the reason they've used it so the NV switch I don't have an power output and heat number or anything like that however it will get a bit warm by nature of being cooled by warmer ambient air relative to itself because the front of this system behind me over there the front of its pushing air obviously through everything it's going through one fin stack for GPU one second fin stack GPU 2gb one and then three and four for GPU two after it goes through those it's going through the fin stack the copper one for n V switch at which point there is pretty warm so there's a reason it's there behind it this sort of set of almost golden connectors in the back is what connects everything together into the front of this so this actually closes and sockets for what is effectively this I guess we'll call it a blade although I don't let the correct technical term over here there are a couple of exposed dies we didn't have this the other day but we have some shots of the NV switch which has got the thinner piece of silicon on it centered surrounded by a couple of SMDs pretty simple looking underneath the copper block and then the V 100 with 32 gigabytes of memory as you can see by four stacks of HP m2 so that's the main change there up from 16 gigabytes previously for the HP m to the front of the system just has some fans in it pumps the air through and then back here we have the power supply so there is some redundancy and rollover and I don't know how many can fail not really the most relevant for our audience but in terms of the power supplies there are I think six of them total so it's three on each side they all plug in it can consume up to ten kilowatts under peak performance and then there's some kind of redundancy rollover failover for when one goes down if one goes down beyond that the CPU is a dual socket single board I think is what's going on and the CPU trays down here along with all the memory so there's one point five terabytes of memory that's all situated down here and basically 1.5 terabytes of memory system 512 gigabytes of memory for he HBM to your cost goes quite high because memory prices right now are absurd the whole unit $400,000 as I joked previously half of that's holy memory I don't think that's too far from the truth but either way that's most of it so I think now you've got more of an in-depth run-through of everything I don't think I've missed much basically the things I was curious about before again envy switches up front connectors here that socket into everything this kind of clothes is pretty cool mechanism actually just pushes like that couple more things quickly so we were given information on the front and the front is about 90% air flow going through it so you lose about 10% air flow he's stuck an anemometer back there that's what you would lose on the front special mesh which is some kind of alloy or nickel or something on the front so that's kind of cool not a ton of blockage looks good all that stuff and also for the env switch is the enemy switches produced about 50 to 100 watts of heat output depending on what kind of load they're under with the GPUs doing about 300 watts and then the front of the box is connected by PCIe to the front of the unit and that's the DG x2 and previously the DG x1 station which is more of a workstation application so that's the high-end stuff from nvidia for GT c 2018 thank you for watching go to patreon.com/scishow his next helps that directly and stored on cameras nexus dotnet to pick up a hoodie like this one I'll see you all next time
