he Water-Cooled Overclockable Server! What?? #Helpful Post

s this your static safe cpu storage

that is area so statically safe what is

an insulator unless it's wet in which

case it's not okay it's only like $1,000

CPU like realistically you're gonna drop

it anyway so like so inside this box is

one of the most bizarre products to ever

land in our inbox I think both Jake and

I had exactly the same reaction gigabyte

sends out this press release they're

like you guys we have water-cooled

overclockable servers and we were both

like we need that well no I think the

first thing I said was but why I

definitely just wanted it and if you do

have that can we use it to replace our

networked video transcode server so

we're gonna answer all of those

questions and more after this message

from our sponsor pulse wave who you can

use to monitor your servers with pulse

video description

okay uh who's taking it

I was just gonna hear it's all you

classic you take it I got it yeah yeah

go for it

I believe in you okay that's not too bad

so the first thing we notice about this

after that it includes some handy tool

estrellas that's nice is that this is a

1u server so this is as slim as you

would expect something like a like a a

router or a network switch to be except

that this thing can handle do I

understand this correctly up to a 70 900

X oh no claims 77 gigahertz 79 80 XC or

a 79 80 XC at they claim 4.6 gigahertz

that is a lot of performance to squeeze

into a form factor like this one so

going over the outside of the server the

first thing we notice is a really thin

honeycomb mesh over here that's for

pretty obvious reasons this thing's

gonna need some serious air flow we've

got those aren't supposed to be swimming

are these I did that you did that so

this is just to look cool are they all

okay there are some of the men measured

we're all say - yeah I'll say - all

right so weird it's like they let

someone like me onto their product team

it says two times u dot - 2 times SATA

hot swappable SSD based there you go

maybe they were color coded back playing

up here it's not all plugged in and

there isn't enough cables to plug them

in so all right well we'll have a lot of

a look at it here first we can check out

the back so we've got one management

port two gigabit network ports that was

a little disappointing 10 gig would have

been nice

serial as well as VGA and then these

these are interesting check this out

so if I were a betting man and someone

said this is a 1500 watt power supply

how many watts do you think this one is

I would probably say something along the

lines of well if this is a per volume

calculation

I don't know 250 or 300 no no no this is

an 1100 watt 80 plus Platinum power

supply that is cooled by this van

and there's two they are redundant so in

the event that one of them fails the

system will continue to run and

basically I expect these to be

incredibly loud wow what the hell

there's 20 fans there's 20 I think these

are like the 23 thousand rpm ones and

these might be the trickiest radiators

I've ever seen these are one new

radiators and they're different sizes -

yeah because this is highly custom so

let's have a look then at how this

closed-loop cooler goes so check this

out we can easily see what the flow path

is gonna be so cool water marked blue

comes in to our CPU where the pump is

also located and then the hot water

comes out goes to this radiator comes

out of this one and then back around

here and then cold goes back into the

CPU so we're actually using both of

these rads to cool just the CPU in terms

of the rest of the specs we've got eight

memory slots so that's quad channel

we've got a single PCI Express slot

which there is no obvious way to

actually plug anything in so what we

actually end up with is oh that's an

interesting one an other more different

PCI Express slot that is broken out to -

16 X slots up here installed sideways

but then also into this one x slot so

wait wait where's the electrical

signaling actually coming from is it

this one I think it's that one yeah it

must be this might be like power or just

for stability like if you're gonna build

a custom board just for this server

right put the USB header somewhere you

can yeah what about all this space here

if you try to put a GPU here it might

even block yeah see that's so weird

because so not only are we limited to

half-height PCI Express cards which is

really gonna affect our ability to

upgrade networking or add a GPU to this

thing this is going to severely limit

the length of the cards we can install

as well when it really seems to me as an

you know a relative lay person like this

could have just been put over here look

you imagine being the engineer that gets

given this assignment I'm sorry you want

to build what yeah so if you could make

a PCB that powers over 2020 3000 rpm

fans that would be great thanks excuse

me why the power draw so gnarly that it

has an 8-pin exactly PS this is an EPS

connector that that provides CPU power

in the desktop systems for mere mortals

those are good for 300 watts I think all

right so what are we going with for CPU

choice I think we're gonna go with a 70

900 X so our current system has a 69 50

X almost dropped it there and this is

also a 10 core so it should be kind of

close in terms of performance although

we're gonna get the next generations

improvements and then we're also going

to get our overclock improvements

because this is going to overclock

better than that ugly water-cooled hood

now the weirdest thing about this

configuration is this building a server

with like Corsair gaming memory normally

you would use ECC memory in a server

because that way if there's a friggin

solar flare and a bit flip or whatever

it can automatically be corrected and

the system can keep running without

interruption but there's a couple of

factors at play here one we're planning

to overclock the bloody thing anyway it

wasn't gonna be it wasn't gonna be have

the same kind of stability you'd expect

from a normal server and to because

we're running an overclockable core i9

processor it actually doesn't even have

support for ECC memory so with that said

we couldn't just choose any old gaming

Ram because it doesn't fit it's even on

like the exact same plane as this

bracket here so it just barely fits

that's nuts I mean the funny thing about

this too is that can't see I've wanted

overclockable servers for as long as

I've been a computer enthusiast but now

that someone actually made one I'm like

experienced enough to know that it's not

like that not have been the greatest

idea what is that so this is a 1050 T I

had to do a little modification we took

the shroud off but there's gonna be

plenty of airflow so it shouldn't be a

problem it's even got its own duct like

it's perfectly fine all right so we're

gonna have a slight issue here - so you

have to take this thing out together

here this connector is actually so close

that it hits it and I'm gonna have to

bend it down while you stick the card in

there it looks ghetto but it's really

not that ghetto what did I catch it I

think I'm in no you cut all oh but it's

in Oh God good enough screw all right

you win

oh so we're gonna put a headless

HDMI thing in here too so when we're

remoting in you get the full resolution

you know honestly I don't even feel that

bad about our get honest here because if

you look at like how the server was

actually designed they literally just

took like a piece of foam here and cut a

hole in it I think that's like and put

it there to keep the airflow going

through the radiators that jank it's

like nice foam at least it's not like

it's styrofoam

it's probably like electrically apple

hitting do it this way

oh well man if Apple starts making

servers again they're gonna have dongles

on their servers you're just gonna see

like a thunderbolt hanging out of the

front of the server with like get your

fiber line and your whatever like okay

should we plug it in there so that's it

yeah let's let's plug this top back on

because I think the airflow is pretty Oh

put this on the right way hold on I can

do this Shh

I believe impressive taking your server

for a walk yeah all right let's go we

got to take care of them otherwise they

get out of shape stuff okay so we just

found a spare spot in our server room

just about we let it sit there yeah just

slide it in there I mean the rails are

really only designed for one server but

like whatever yeah it's not like that's

a really heavy one anyway that is really

really loud like honestly here hold on

can we close this door for a sec yeah

yeah clearly even with all the sound

deadening that we put in this room which

people mocked me for but actually works

for it works phenomenally thank you

what's that yeah yeah it penetrates like

I'm over by the green screen now that's

an actual problem like ya know I don't

know if that's gonna okay it just dialed

it back a little yeah okay right now

it's fine so

process of overclocking this thing was

actually kind of a nightmare but we're

there and our CPU is running at a cool

4.7 gigahertz now it wasn't actually

that easy to get it here gigabytes

manual for this server doesn't exist yet

yeah and there's some extra steps so in

addition to setting your core voltage

and setting your CPU multiplier like you

would overclock you on a desktop board

you have to key some magic value so

let's go ahead and hit it with a stress

test that 65 watts that I don't know 69

69 yes

no bad all right so let's start a stress

test make sure she holds 100%

utilization 4.7 gigahertz what kind of

temperatures are we looking at 62 1750

75 degrees heck yeah so we loaded some

stuff on here we've got regular

Cinebench which we're gonna run real

quick here and by real quick I do mean

literally real quick this should be very

fast and then to address that Cinebench

has actually gotten to the point where

very high-end processors run it too fast

to use it as a reliable benchmark we've

got the new unofficial it's called

Cinebench extreme extreme we're gonna

try that out as well so kicking things

off we got ourselves 2500 points which

is pretty good now let's try extreme

which is basically just four times the

resolution this one first

whoa look at those temps yeah they're

starting to get up there that is quite

the load Wow

we are above ninety degrees on a handful

of course here you might say that this

benchmark takes a hot minute okay I'll

give you that one oh we did detect some

overheating but our throttling

percentage is zero and it finished so

she seems to be 656 which I have no

context for because this is a brand new

benchmark I've never used before so why

don't we go ahead and shut all of that

down

let's do our our network network render

okay so I got just down there that is

one of Adobe's sample files sure so

we're just open up final one and we're

gonna export this like we would an LTT

video so the 60 megabit per second and

then 75 cool at 4k and it is fully

utilizing our CPU so one thing that we

observed about our network render server

way back when I had intended to use like

18 cores eons in it or something was

that there's a limit to how many threads

media encoder can actually use so it's

better to have fewer higher clock

threads than it is to have many many

threads in a lot of cases which is how

we ended up with an overclocked render

server in the first place so this looks

like it could be a viable replacement so

the results are in and Cinebench both

Cinebench and Cinebench extreme gave us

20% increases in performance that's

actually quite a bit more than I was

expecting right so the increase in clock

speed is 17 and a half it's still 20% so

we're getting in like what 3% increase

the IPC but then in Premiere we actually

got a 30% uplift going from what it

doesn't that thing having it a GTX 980

and a 16:9 50 and this 6:9 50x not

frickin bad but the problem is it's loud

the other problem is that this whole

this whole experience still hasn't

really enlightened us as to what that

crap this thing's actually for so Jake

intrepidly sent an email to gigabyte

asking them what is this for why does it

exist why did you build an overclockable

1u server can't even put a GPU like that

doesn't really have networking like what

would you even use this for and the

answer is the finance industry high

frequency trading so you would take this

server you need the highest possible

freakin performance you need something

that's air-cooled so it can just be

slotted into your existing server room

you throw one of these puppies in or

maybe even a newer one so this is a 100

gigabit InfiniBand card so super low

latency

yeah wire that up to your net

and the difference in these like what

are like milliseconds maybe five

milliseconds the difference there could

be hundreds of thousands or millions of

dollars in that industry

a couple hundred traders over a year

like it can be a big increase for a

small amount of money so the investment

in one of these servers makes a ton of

sense there but for us I'm not running

out and recommending that everyone go

and buy one of these it's just too

freaking loud it's it's very loud

otherwise it'd be pretty sweet though

yeah like maybe we should just

re-inflate whatever like the second

layer or we could even just put like

more sound deadening around that box or

we could just upgrade the server that's

in there right now but we won't be able

to do that without getting paid by our
