okay so we built seven Gamers one CPU a
$30,000 computer running unraid as an operating system and using it and some
really cool open- Source virtualization technology to run seven discret gaming
virtual machines at once all fully capable of like high performance gaming
so that was cool $30,000 computer two thumbs up very awesome 10 out of 10 IGN
Etc then what we did was we showed it off at CES okay so we got that out of
the way the world was able to see it in person then after that we brought it
back to the office converted our entire conference room here into a land Center
and had an inter office gaming competition complete with tan being
terrible at video games yes the very worst one here except he did kill me
once and you can check that video out here so you might be asking yourself why
is lion is still milking this damn thing what could possibly be left to do and
the answer is of course we're going to overclock
it Intel brings ddr4 to the mainstream
with their core i7 6700 K and core i5
6600k processors check out the link in the video description to learn more so
the first step anytime you do any Performance Tuning is to get a baseline
measurement because if you don't then you have no idea if the dials you're
turning are doing anything at all so I'm
going to introduce you guys to the benchmarks that we're going to be running cinebench R15 is going to tell
us what we need to know about CPU performance we are going to be using
Crystal dis Mark to tell us what we need to know about our SSD array performance
IID to 64 cash and memory Benchmark is going to be interesting especially once
we run it on all machines at once more on that later and we're going to be
using fire strike extreme to see how our
gpus are doing some of the stuff that's open is just tempor monitoring and stuff
like that and finally we're going to be having a look using our handy dandy wall
power meter dudad here at what kind of power consumption we see when we're
hitting the whole system at once but let's start with a single VM Baseline
with all the other ones sitting idle and I'll show you guys on screen hopefully
right now how I plan to go through this entire test suite and show you guys the
scores so here we go we're getting a cin bench score of around 600 we're getting
Crystal dis Mark scores in the uh area of sort of you know two uh gigabytes per
second reads and around 400 megabytes per second rights to our array our
memory scores we're seeing about 5 GB
per second so on average reads and wrs to our quad Channel ddr4 memory and our
3D Mark fir strike extreme score is 6148
so the next test and this one I will
need some helping hands for is going to be to hit all 7 VMS at once for our
Baseline score to see what happens when they have to actually share resources
which especially for things like memory it's not very pleasant sometimes okay so
I've assembled a crack Squad of helpers whose intelligence and physical
coordination uh lead me to believe that it is probable nay likely are both kind
of the same thing that they will be able to perform the skills that I set out for
them today task actually not skills don't worry too much about that basically what you guys have to do is
all press a button at the same time oh that's that's not not going to work okay
Colton you're fired again thank you okay
so two of you will have to press two
buttons at once at the same time Johnny
you got this okay Johnny you're on machines one and two yvon you're on
machine three Colton you're here Nick you're here and I'll go over there and I
will tell you which button to press and you will all press it at the same time
you're going to click the button that says Run next to CPU in the cinebench
R15 program has everyone got your cursor positioned yes okay so I'm going to say
don't do it yet I guess teran's not here I don't have to give instructions like
that okay it 3 2 1
go okay so you can see here with our seven instances of cinebench running we
are actually pinning the entire CPU here
at 100% usage that was exactly our intent and will tell us without any
extra a turbo boost for only activating a couple of cores at a time how all of
our VMS can run in a worst case scenario where they are sharing as much resources
as possible okay so we're scoring around 500 points which is about 100 lower than
we did when we were just running it on a single VM fascinating okay everyone
ready 3 2 1 go okay so this is
interesting on the read side of things really there wasn't much an effect from
the numbers I've looked at so far but on the right side of things some of our VMS
were so starved for disc time that they
actually timed out on their sequential right Benchmark very very interesting
this isn't something we're going to retest after we overclock because we can't overclock storage but uh I just
wanted to have this as just a for my information sort of number Ida 64 cash
and memory Benchmark it's a gray window this one I'm really interested in
because desktops really don't care much
about their memory bandwidth these days I mean dual Channel quad Channel DDR3
ddr4 it's all fast enough but if you're trying to hit
something with s VMS at once I'm
expecting the performance to be affected somewhat it's this is really interesting
so you can actually see the systems are running the benchmarks at different
speeds NX VM over here so this is player
number five is actually still running
the memory benchmarks or at least at least it was before I uh and mine is
almost done running all of the level one and level two cash benchmarks so it does
seem like their ability to even run these tests is affected by the fact that
we're hitting them all at once here we go last one position your cursor over
Run 3 2 1 fire strike
extreme thank you for that clicking like random times like okay I guess that's it
3 two one f with extreme okay you guys are dismissed for
now thank you I'll call you back once I overclock the system so check this out
this is what our uh memory and cach
benchmarking looked like this is what our benchmarking looks
like in fir strike extreme so with seven
instances of it running we're actually getting up near 100% utilization closer
to like 90 here
okay very interesting so 3D Mark scores not affected much by our CPU and RAM
sharing because 3D Mark is mostly dependent on the graphics card and each
VM has its own R9 Nano so all that's
left now to do is to record our score so we can create some average score graphs
for you guys and establish our Baseline so that we can find out if our
overclocking helps now most Server Motherboard makers
do not have any overclocking features but this is a Seuss and this is
technically a WS or workstation board so
in the AI tweaker menu we've got their
AI overclock tuner which has two settings neither of which I have played
with at all manual and OC
tune so I'm just going to go let's OC
tune it level three and find out if the system works
there's a very good chance this not going to work I have not tested did
this at
all so this is actually a really bizarre Quirk of this system it starts up
here oh oh if it turns on at all it
starts up here oh wow yeah that's not
posting let's clear simos and then
uh we will go from there
okay something to see if that does
anything oh that was it I need this bar
to get past like
here oh that wasn't it like I I
oh I know what it is because we did a
seimos clear that bio setting that I need the 4G
decoding setting is not enabled so we
are not able to boot with all of these PCI
devices so maybe by
unplugging all the video cards I will be able to have them not
get picked up and I will be able to get into the
BIOS this is how you remove the graphics
cards from Seven Gamers one
CPU there we go okay they're out so
now can try again okay so that was
it the problem with having a system that doesn't Post in its default
configuration okay so let's try manual this time um
my understanding is that on these types
of boards you can expect somewhere in
the neighborhood of like5 MHz so just
for LS let's try 105 and see what
happens I'm guessing not a whole lot and
that's what I
got okay then okay so after four
attempts we're back in the BIOS our setting did stick but obviously didn't
work so let's try a more conservative 103 which would be a 3% overclock okay
so because we have no video card we have to use VNC to get into our VM and find
out if everything is working as intended
well that is not reporting correctly at
all so that's a thing so we're going to have
to run a benchmark and find out okay I
tell you VMS really screw up hard
Hardware reporting both CPU
Z and Ida 64 are reporting numbers that
would indicate that our CPU is not overclocked but cinebench is reporting
that it is overclocked and even though these scores are not directly comparable
because we don't even have any of the other VMS booted we're getting 900 in
cinebench which would indicate that everything's working properly at the
very least so now we can proceed to the next step and put our graphics cards
back back in okay all our video cards are showing up which basically means we
can start the array and fire up our
VMS did it just do that or did you do that hey all
right say that again so now it is time to overclock our video cards now the R9
Nano isn't uh really known to be much of
an overclocker uh but we're going to go
ahead and increase the power limit as high as it goes and we're going to
increase our core clock to like I don't know 1050 and see what happens hey
Graphics 1050 MHz just like that I guess
water cooling helps a little bit with the whole overclocking the R9 Nano
situation very nice what the hell
afterburner is detecting all seven gpus
that shouldn't be possible cuz we've passed them through
to separate VMS it's also detecting wow
afterburner doesn't know what's going on so it's got them all being used while
we're running The Benchmark so it knows there's seven but it doesn't know that
it's only using one of them and it's just cloning this core clock graph which
actually has the card not reaching uh
not reaching 1,000 mahz anyway
so I guess all that's left now then is to run some benchmarks and find out if
we got any benefit for our trouble everyone ready overclocked cin bench
Benchmark what damn it Nick if ID wanted someone to just start The Benchmark
early I'd have asked Taran to help please work please
work please work no no what no just kidding player
whatever it is so it's 1 2 3 4 5 6 7 and
then you put OC score in a bench but my
keyboard says six don't worry about that
okay actually that does seem to be
faster good yeah 40 points better on
mine 30 points everyone ready ready 3 two 1 run
it please don't
crash oh M oh
why it's okay give it
time power draw 1,600 Watts so did
everything but Nicks launch yeah okay so
after much struggling we managed to achieve whopping overclocks of anywhere
from zero to 70
mahz on our graphics cards you building
fire strike extreme scores in the very
very close to what we were already getting range leading us to believe that this
whole thing was a terrible idea but I'm really glad that you guys got to come
along for the adventure with us because um that is what we do on this
channel that is what we do this is a
sponsor spot I have been looking forward to for quite some time we recoverd
dat.com what they do is pretty obvious
they recover data and why we're affiliated with them will be pretty
obvious if you checked out the data recovery Vlog which if you haven't
already is a pretty uh pretty exciting
piece of content as far as they go on this channel anyway they gave me some
bullet points to talk about and I will do that but then I'll get into why
they're so special to me so first of all they're one of the only dat recovery
companies to invest in R&D so if the technology to recover your data doesn't
exist they create it they're fast they're techsavvy they have friendly
customer service available 247 and that was indeed my experience their data
recovery guarantee policy means that if they don't recover any data there is no
recovery fee they have worldwide emergency data response options
including onsite remote and in lab that's 247 365 they've got
state-of-the-art equipment utilizing today's most advanced technology with
proprietary in-house developed tools they've got iso4 class 10 and iso5 class
100 clean rooms to enable them to provide a Optimum solution for a
recovery environment and basically what it boils down to for me is they got my
data back it was an extremely
complicated raid array not a recommended raid array so I had three raid fives
that were Hardware raid fives on separate LSI controllers and then I had
those striped together in raid zero for an effective raid 50 so three raid five
stripes in Windows I thought it should be pretty safe because I can lose up to
one SSD per controller before I should run into any issues but what I didn't
account for is losing a controller
outright so one of the controllers failed causing the array to go into an
unrecoverable State and we recoverd dat.com had me plug in all those 24
drives to a host bus adapter and they
were able to remotely using their own Linux tool reconstruct the whole thing
allow me to copy it off and basically
save my turkey which uh thanks to those
guys and if you guys have a data recovery emergency then check them out
