THIS Replaced Every PC in my House!

portions of this video are sponsored by LastPass like five years ago on the web show Luke and I made the prediction that even if cloud gaming could never solve its problems with latency and game licensing the hardware that was used to run it was gonna get so powerful that it would be feasible to use a single computer as like the computing brain of your house and run all of the gaming machines under a single roof off of a single box and my friends it has happened AMD's epic line-up of server processors are available in configurations with up to 64 processing course guys that is enough CPU resources to run 16 virtual machines each with a quad-core processor off of a single chip in a single socket and guys these are not weak course so we don't actually need quite that many of them for my house so we've gone with an epic 7502 pea that's a 32 core processor that runs that 2.5 gigahertz base and actually boosts up to 3 point 3 5 gigahertz so we're gonna be using this as well as all of this to convert all my computer's to run off of a single motherboard my personal gaming rig which I also use for streaming very occasionally my wife's rig which uses for work and also very occasionally gaming so I like to still keep it up to spec this one's not actually running right now because we got a broken Thunderbolt optical cable the gaming machine that runs the world's most comfortable gaming setup - that I use for bulk storage and as a plex media server and finally the home theater PC / vr gaming rig that's in my living room so managing credentials between all of these different machines can be a bit of a hassle thanks LastPass for sponsoring this portion of today's video that's why I use our sponsor LastPass and I've been using them for years now LastPass is browser extension and app makes signing into your accounts across all of your devices fast and easy without writing down passwords learn more about it at the link below or by waiting until the end of the video thanks to LastPass for sponsoring this portion now on to the rest of the video [Music] what does a machine that's powerful enough to take the place of four to five others look like let's walk through all this back starting of course with the processor so our seventy-five o2p here it's 32 cores 64 threads but more importantly than that it's got 128 PCI Express Gen 4 lanes on it that means that almost no matter what we plug into this thing whether it's n dot 2 drives for high-speed storage or regular SATA drives or a ton of PCI Express expansion cards including graphics cards everything is going to be getting the full bandwidth that is absolutely incredible and all while consuming only 200 watts which sounds like a lot but remember that's going to be four to five CPUs so now as for what we've got it installed on this is a gigabyte ends at 32 AR 0 this is one of the few standalone extended ATX motherboards that has full support for PCI Express Gen 4 almost across the board pun definitely intended it's got an incredible amount of connectivity including a bunch of nvme storage regular storage 7 PCI Express slots only two of them I think are even 10 3 which is unbelievable and it's got a remote management port as well as one of these OCP mezzanine card ports where we've got an Asus dual 10 Gigabit LAN card so this thing is going to have high-speed connectivity both in and out now as for our graphics cards unfortunately unless you go full enterprise Nvidia doesn't currently support splitting a GPU into multiple virtual machines the same way that a CPU manufacturer does so we've actually got four total graphics cards one for each of the gaming rigs provided by Nvidia and then of course asus rog so an RT x titan for my gaming rig a 2080 TI for the vr rig and then a couple 20 70s for the ones that just need to be like basically up to spec finally this is amazing we have 512 gigs of DDR 420 666 memory from Mikron they sent this over for this project today and it's running an 8-channel mode that means we have a ton of bandwidth each of my individual games is gonna have effectively dual channel ddr3 bandwidth I'm freakin believable not to mention that each one could have over a hundred gigs of RAM by the way if you're into tons of RAM make sure you're subscribed because we've got a project up coming soon where we're gonna have two terabytes of RAM on a single epic processor now in a perfect world what we'd really like to do is install all of our graphics cards directly in the slots put water blocks on them so they only take up a single slot and you know water cool the whole thing so you get that that density but because we're at the really proof-of-concept phase right now we're just going to use these PCI Express extenders here we go to run the cards out of the motherboard like this and then we'll run our power cables a little something like this it's not the prettiest way to do this but it's functional and you know all we need to do is plug into it so you know the card can just kind of sit there last thing I'm installing here is a couple of USB 3 cards we're gonna need to pass through USB 3 ports to our virtual machines in order to have USB 3 ports and unfortunately this motherboard only has three of them one of which is going to be taken up by this USB drive that we're installing our OS on I'm gonna be using on rate just because I'm most comfortable with it and also because I use on raid for my personal NAS at home so if this works amazingly and we end up deploying this in the long term that is how I would end up using it just with a bunch of hard drives connected as well Oh actually wait I forgot about the internal USB 3 ports deter there we go we can use that for our lesson so now that our machines assembled we've got all this power but we don't really have a solution for how to pipe it around the house so to speak now we used to do this with Thunderbolt back when I set up my gaming rig in the next room over along with my wife's but between the reliability issues with the Thunderbolt 2 optical cables random we're like displays - look at this this has been sitting here since we started filming this failing to go to sleep and the lack of especially server motherboards with like four or more vulnerable ports on them we needed another solution now display was easy this is a 50 foot light link DisplayPort connector from Sewell direct that they sent over actually for an unrelated sponsor spot a few months ago hey these are finally come in handy but USB 3 was shockingly difficult until we found this this nondescript brown box is from icrons-- technologies who are shockingly headquartered about 30 minutes from my house that's super cool this is the Raven 31 24 USB over fiber extension and this is the only USB 3 extender on the market that uses multimode fiber with backwards compatibility for both USB 2 and even USB one trust me guys we looked everywhere they have extremely low latency on the order of microseconds which is very important for our VR gaming setup and thanks to their extreme USB technology funny branding aside they can go up to 200 meters with complete transparency that means no drivers and no funny business whatsoever the problem is that this right here is a connector that you are unlikely to find in the average house so Colin hasn't actually said much up until now in this video and you're probably wondering why he's here oh you're probably not wondering that because you haven't seen him he's gonna be running these what are these and what's special about them so these are fiber optic cables we have two different ends here strictly because we want to connect them into these well plates oh okay small plates the only option was an SC connector so we're taking this SC connector nope I broke that good thing we don't need it anymore not anymore and everything with fiber optics has little on it because we want to keep these fibers really clean and so we will plug in the SC connector on one side yeah over bucks and then on the other side we're gonna plug in the same SD cable and that leaves us with two LC ends and these LC ends are what interface with our boxes and now it's as simple as that plug and play it's not that hard just don't break these cables they're very fragile and expensive and expensive well in the context of how much this cost yeah they're not that bad these are really cool plates where did you get these so these are data Pro they're a company down in the states somewhere might be Canada I can't remember honestly but they do custom wall plates and you can get them laser etched and you can get whatever you want they have a real cool configurator on the website you can just plug in all the port's you want and even send in the the keystone connectors so we plug in like our fiber optic DisplayPort into here and then we just have a port and then in normal plug so we just throw this Linus in yvonne's machines we throw that in the wall there we just plug in normal cables bippity Boppity off you go so this is the one for the VR machine and then this is the one for world's most comfortable yeah that is sick we're gonna start with a VR system run so what challenges are we expecting so the hardest part of this whole ordeal is keeping these cables from breaking we have to be very gentle it's it's just a glass fiber so we're going to gently attach them to this fish cable and we're gonna fish it all the way to the server room and then we're going to drop some down to the VR setup and then bring some all the way around to here by the way if you smell pee around here it's because our old cats used to pee here so it's pee so in order to get access to the wall here careful careful it's it's cable man it's real tight back there so you want to just spot me while I pull it out okay we good we good okay so to get access to the to the wall back here we're just gonna need to pull the media console is that enough yeah I think so okay and what we're gonna do is we're actually gonna use the same wall box from the existing Ethernet run except this time we're gonna bring it down with fiber and DisplayPort and then we're going to use that USB extension which conveniently also has ether yeah pipes are right through to go ahead and provide Ethernet for the rest of the devices here now it's not ten gigs so at some point I'll probably run another one you know just do the thing it's only five gig for now weird no no the ethernet is probably one game which is like realistically fine yeah okay go do this okay ah bike bike on ye also there's definitely something actively in here what yeah there's like wet spots my roof is leaking no it kind of smells with pee I wonder if the cat got in there who the cat or something like there does the Sun hurts oh sorry it's okay I just have to wash my pants wash everything wash all the things yeah so whole cell really need this to boot up like no I have drilled a hole in line with this pot light and I'm really hoping that the fish tape that I shoved down that hole into the wall is going to line up with the plate here I kind of doubt it it's it's like a foot too far in but worst case scenario I'll go back drill into their hole and just try to get in the next wall space so this is the ethernet that was run outside so I can't really use it to fish my fiber optics back up the hill so to speak all right so I think what we're gonna do is unplug all the graphics cards get this booted up and then start plugging them back in one at a time we've seen this before with six workstations one CPU and the good news is because we haven't water-cooled it all together and created a custom chassis there's plenty of time to sort out these kinds of issues the big thing we're testing today is whether the fiber optic USB and DisplayPort solution is actually any good yeah dead squirrel what what it's a dead squirrel in there oh my god that's disgusting yep okay it's not moist anymore if that's what you're wondering okay sorry I've shoved the fish tape all the way down but there's no C in it so and I'm in line with this box I think so I'm in the next wall space over so I think I'm going to mark out poke a hole and pray we're gonna see if we can find the tape in there I get to wreck lionesses house yes I think I have like a 50% chance of finding it in the wall since 70 I did say 70 earlier I just dropped it down to be realistic so I found the edge of the next stud yeah and so that's where I think I am in the wall given the pot light so I'm ready to poke a hole I just need to kill the power okay and then we can fish the cable down and hope we find it okay well there's nothing powered up over here that matters so go ahead and start flipping breakers I they're sort of labeled Oh what helps why did I drill two holes because I should have put the first hole on the edge of where I need to cut so I can get the saw in there so I think I know what the issue is this board is still running the release BIOS from four months ago so there's a new one that apparently fixes blue screen issues with graphics cards apparently fixes issues with Intel network cards which is exactly the kind of NIC that we had plugged in so CD FS 0 current directory not specified what does that mean so we've put a hole in the wall this guy fits quite nicely if they do say suing myself and I'm gonna go up to above this and just try and shove the fish tape down there and see if I can find it like a fox nice this SC connector is too big to fit in the hole that I drilled in the joist upstairs so we're gonna run the LC connector which is what actually plugs into the devices this guy will screw on to the and here I'm probably doing this wrong so any electricians or people who pull data lines professionally don't at me we are going to take the actual USB fiber not just the DisplayPort fiber this nice small end that I can actually fit through the hole I drilled try and pull mostly from the plug in the jacket got a nice little missile drag up okay so BIOS update seems to have worked I am in under 8 everything is behaving as it should but I have a couple problems to solve one is that my old Vee disk so with a Windows 10 install on it it doesn't seem to be booting for some reason not sure why I think we're stuck at a boot loop you've got to be kidding me I think we're stuck in a boot loop you've got to be kidding me I see that that's the same thing you've got me last time oh there's a pattern in there where'd you get that from my chair what the heck please just take these graphics cards to show up Wow I still need a few more things to go right there okay so devices that we need to plug in then oh here's something I really didn't think of ah Colin yes sir how many display ports did we run down here just one missile you said to run thinking yeah there's no way to like get another one down here quickly and easily we don't have another one hmm thank you okay I have an idea we are going to plug the primary display in upstairs we will plug the VR headset in down here oh why how did I not think of this let's try it just with the main TV first then okay so things we need plugged in this that's our keyboard mouse dongle doodad is there a front one no I guess they're all in the back okay that's fine and I pulled the plugs off we're connected and now we have the correct connector to go into the back of the extender pull the little plug send it - oh is that hdmi displayport no signal should we just test with something that we know works yeah sure why don't you go ahead and plug it into the blue one over there yeah okay yeah I got to be that contortionist again hold on a second what did you unplug it no just sitting there oh did you not plug it in plug into the 28 ET I then I guess 20 80 yep no signal that's heartbreaking okay we're locked in DisplayPort so hopefully at some point it'll just go nothing yet but the little light at the bottom is flashing orange wait what am i plugging in the wrong thing these are directional I didn't realize they were directional oh wait wait wait got it okay new plan since we had to rerun it anyway we're gonna run the two here so we can have the TV and the VR setup running at the same time I mean hey look at that it's up yeah yep oh okay honestly I think we gotta call it here today and pick this up again tomorrow with GPU pastor working now we can focus on setting up all of our VMs and getting our peripherals working as you guys might be able to tell I was up for quite a few hours last night getting this all configured so not really feeling my best anymore but the good news is we're ready to show you guys all four machines are running super smoothly right now I'm just extracting a copy of the Cinebench mark the only real way to tell the difference between them is to fire up task manager and look at their different specs so this one's got 128 gigs of ram 6 cores I actually have SMT disabled on the CPU due to a BIOS irregularity on our motherboard so those are 6 true cores and these are 8 true coarse as opposed to you know a virtual core in a true core so a true cores and finally what's this a true course now remember guys individually these scores might not be crazy impressive or anything but you gotta remember that this is for instances running off of a single chip so let's go ahead and go run run run and we are two cores short because I've reserved two of them for our virtualization hypervisor they are all lit up right now ladies and gentlemen this thing is working hard now let's just see how they do in terms of performance here we come in at anywhere between around 2700 and 2000 but that's without having our SMT enabled and that's with all of them running at the same time so what I'm expecting is that even without altering the core counts and run one of these again we would actually get a higher score if not all machines are going full-tilt at the same time which would be a pretty unlikely scenario and as expected we got 2900 points without changing any configuration just thanks to our CPU being able to boost higher so that's great everything is performing as we would expect so it's time to throw some GPUs back into the VMS and try and light these monitors up ok in theory everything's linked up so now it's just a matter of unplugging my Thunderbolt dock here and switching over to optical DisplayPort and optical USB Oh execution error oh crap okay I'm gonna please eight peripherals lit up so our USB to backwards compatibility is running okay so now what we need to do is get Yvonne's turned on this is great so we had a connectivity issue there our USB three was flashing all we needed to do was unplug and replug our fiber pass-through and we're good to go Oh 150 gigs of ram ladies and gentlemen so uh this is it Colin and I are gonna try and game on both of these machines at the same time over fiber optic connections you might say we're gonna game at the speed of light you were waiting to do it if I didn't in case you're wondering why it's rise of the Tomb Raider and not shadow of the Tomb Raider I set up the VMs with really small virtual disks and shadow didn't fit and I could have expanded them but then it would have taken longer to copy them back and forth over the network and stuff so this isn't overdoing and the craziest thing about this kind of virtualized setup is that even though we're using the same machine we don't have to both play the same games some not some game console you know I want to do some you know 3d rendering or some crap on my CPU Colin shouldn't feel it at all in his game while I crank the 8 cores that are assigned to me pretty sick Hey so for world's most comfortable gaming it's about to get uncomfortable because we actually totally forgot I forgot this doesn't have DisplayPort so our wall jack is kind of useless we pulled that out and then this was the only long HDMI cable we had on an the three hundred footer and we couldn't get it on spool to get you know what just whatever don't worry about it fiber optics are so cool like that is a 300 foot HDMI cable and we are at 4k 60 frames per second right now is that not freaking awesome and of course guys just you know proofs in the pudding right we are not running off of this PC now something I haven't tried yet is whether we can actually run 120 Hertz 4k or oh wow that was quick and works just fine all that smooth is freaking awesome 50 feet of 120 Hertz 4k oh and our control panel showing up now okay let's play game man I really hope this works so this is the twenty ATT I equipped machine so theoretically performance should be flippin awesome so far everything just works you just plug stuff in and USB to USB three this is 4k 120 Hertz over long distance we're running it like 80 FPS yeah it's a bit of an older game but this thing is freaking cranked guys and that's my gaming PC right there look ma not actually hooked up this is cool too so because we're using this USB extender box it has lots of power going into it and that reboosts the signal we can even plug in peripherals with long cables like an Xbox controller or something like that boom plug and play the thing about VR is between the cameras and the extremely latency sensitive nature of it any problems with either your display connection or your USB connection are going to result in a very very bad experience so I think I found a problem generic super speed USB hub here is showing up as a yellow exclamation mark and it only happens when I plug in the index it's okay I've got an idea right now I'm using this Asus card with an AZ media chipset to plug into my optical box and I'd like to swap it out for another one but I don't have anything else handy which got me thinking what do all our TX Touring cards have a USB type-c port for that VR link or whatever it's called thing so what if I plugged in a type-c hub and I plugged into that and pass that through see what happens well the good news is it works at all I wasn't a hundred percent sure because I know that it's a slightly non-standard implementation of USB type-c but the VR headsets still not working let's go ahead and give it the all the old replug right now we've got one of two possibilities either our miracle USB box is not a miracle or there's something about virtualizing our USB controller that causes it to have virtual hubs in the chain or something that's causing performance issues so to diagnose this we're gonna take my vr gaming setup we're gonna pop it in the room upstairs and see if that works with the USB box well it picked up we're in game I will say last night I did manage to get this far connected via the virtual machine but it wouldn't go longer than about 10 or 15 seconds without the tracking going all wonky which was making me pretty sick so just because it's going now doesn't mean that we're out of the woods yet so far I've had no performance and no tracking issues which is really impressive when you consider that between the PC and the VR headset there's not only my optical links but also the long tether so what all this means then is that the concept of having our computers separated physically and all in a centralized location and then accessing them over optical fiber in our homes is found it's just a matter of the cost becoming controllable and maybe some software or driver issues being sorted out pretty freakin cool thanks LastPass for sponsoring this portion of today's video LastPass makes it easy when you're setting up new computers or when you're traveling and you want to get access to your passwords with LastPass not only can you store passwords and then recall them on desktop with their browser extensions or on mobile with their apps you can also store things like Wi-Fi access codes personal health numbers or anything else that you don't want anybody to be able to access it is so easy to reuse the same password from one account to another but if all the password leaks that we've seen over the last few years have taught us anything if that that is absolutely the worst way to go about things so with LastPass you only need to remember one password and all your other passwords can be completely different or even randomly generated using last passes own random password generator even if you're capable of remembering all your passwords LastPass just makes things more convenient because it will even autofill your username and password on many mobile apps on both Android and iOS so go check it out at the link in the video description and massive thanks to LastPass for sponsoring this portion of our video hopefully you guys enjoyed this man this was about as chaotic techie LTT as it gets but I am super thrilled with the potential of this solution if nothing else it could be used to take all the noise and heat generating components away from places like your media room where you don't want it and consolidate it somewhere out of sight and out of mind with no performance penalty that we can detect flippin sick do you guys want to see more great projects like this make sure you're subscribed and if you like this kind of virtualization stuff maybe check out our previous video six workstations one CPU where we took a single tower and edited 8k video six times off of it with six independent editors

this is lowkey a dream ive had for a long time. i want a house with a server type room. basically a closet i can keep a pc in. I want that PC to be overpowered as heck, but i want to be able to port into it from anywhere that would typically have an ethernet connection.

dont necessarily want the complicated, VM stuff he is having to do here. but i think in the future you will be able to do this much much easier

[u/YouDamnHotdog]

What would be some alternative options for Linus if he didn't wanna spend $2k on a fiber optic-USB converter?

What is the maximum range of USB range extenders?

Isn't USB-over-CAT the go-to solution?

How about USB over WiFi?

Edit: This is a USB 3 extender cable that converts it to fiber optic and back. $200 for 100 ft. Linus could have gotten just one of those for the VR headset. All the other devices are probably USB 2 spec.
