Apple Mac Pro 4.1 CPU Upgrade Guide | 6 Core Xeon X5675

Apple Mac Pro 4.1 CPU Upgrade Guide | 6 Core Xeon X5675


welcome back guys to part 6 of my
tutorial series on the Mac Pro 4.1 5.1 the so called cheese grater
Mac Pro and maybe if you look in the navigation below you can see what we
already upgraded inside this Mac Pro first we did the Bluetooth fix for the
Bluetooth laggy Mouse issue then we created an installation media and I
showed you how to install mac OS high sierra on this 4.1 mac pro which
officially apple doesn’t support but which i already did and tested and it
works really really fine just by doing the firmware update then in part 3 i
showed you how to put in a 1 terabyte solid-state drive with full SATA speed
with this Other World Computing Mercury Accelsior adapter then we talked about
graphics cards and as you can see then we did the memory upgrade the memory
is already in this is the old 2 gigabyte modules which i replaced against 8
gigabyte modules server grade modules which worked really really well hey by
the way boosted my performance and is really really quite nicely really made a
huge difference to have the 6 gigabyte replaced with 24 gigs and maybe as you
can see here now in episode 6 we’re gonna tackle the processor and yes for
this i had to do some waiting and buy a special tool you will need like a
special tool like that and i’m gonna show this to you in a second and the cpu
the upgrade that i have here i bought on ebay and I’m gonna take this out of the
box for you guys in a second but let me tell you this is a 6 core cpu and in the
Mac Pro right now it’s a 4 core and also this has faster clock speed and the
interesting part about the CPUs is also that depending on which CPU you use your
iMac can support different types of memory the CPU that’s currently in my
iMac I believe only supports 24 gigs of memory but this CPU
supports considerably considerably more and I’m going to show this to you in a
second we’re going to head over to the Intel website and looking at
specifications and the real difference is that the old CPU I think when it came
on to the market was like worth five hundred dollars and the server grade and
it has the designation W and the server grade CPUs with the designation X first
of all there are dual dual CPU capable so if you have a Mac Pro with the dual
processor board that supports it but all these more expensive X CPUs besides the
supporting more memory also had a much higher price when they hit the market I
think like the one that I have in right now was 500 and this is what this was I
believe like 1500 so like these CPUs I think had triple the price I think we’re
just gonna get started right now here in a second I have prepared everything you
know where we are in the in the time in the progress line of the tutorials if
you want to see another tutorial just click on the on the links below and it
will lead you to the corresponding tutorial and now let’s change the camera
position and I give you a close-up shot from above I’m cleaning up the CPU
and then I’m showing you how to install it and what you pay attention to and
then we’re going to do a performance test I already did the geek bench
scoring and then we’re gonna compare the old geek bench score with the new geek
bench score to see what performance gains we got by following all these
steps in improving our 2009 I have the 4.1 so that’s an early 2009 Mac Pro so
it’s 9 years old but I think it performs really really great because of the
upgrade ability so let’s get started so guys before we actually start obviously
we need the CPU and also like I told you earlier we need this special tool to
remove the heatsink and maybe you want to have a little bit of microfiber cloth
and then also what comes in handy is this arctic clean the terminal remover
and the surface purifier now I bought the CPU on
eBay and what I immediately noticed and I hope this shows up on here when I take
this out of the box by the way this is the Intel Xeon X5675 with
3.06 gigahertz and there is a particular reason why I picked this one over the
faster ones because I went on the intel page and I saw this has a way lower power
draw then some of the other models so the benefit is that I will not only get
six cores a faster clock speed but also reduce power consumption which i think
is a good good good value and if you pick the top of the line module sorry
the top of the line processor obviously it’s going to have a higher clock speed
but it’s gonna cost twice as much and consume considerably more power and I’m
gonna after I’m installing this I’m gonna I’m gonna show this to you on the
on the intel page but what I wanted initially to say it’s like when I
ordered this on eBay obviously it’s the used one but you’re gonna be really
careful like because the guy who sent it to me there is still some compound on
the CPU and obviously on the heat spreader I don’t really care much about
it because I can just remove it but obviously it’s not so good if it’s on
the bottom side so I’m always a little bit nervous getting like a used CPU
and putting it in because I’m really afraid of ruining my system I saw
some videos online some people they did the CPU replacement and in the process
potentially permanently damaged their system and maybe I think this was like
two two dudes somewhere in a sound studio upgrading to faster CPUs so
that the sound engineer could run like these crazy effects at crazy effect apps
and that was like a really cool tutorial so maybe I put the link below the video
below in the video so that you can watch this too because the guy explains how on
I think this did pertain to the dual-processor mac pros that when
screwing back on the heatsink you could potentially if we screw it on too
tightly squeeze some pins if I’m not mistaken my the single processor Mac
pros are not affected by this as I’m going to show to you in a second but
yeah so what I’m gonna do is I’m gonna use the thermal purifier and this
microfiber towel clean up the rest of the compound that’s on the CPU and make
it ready to install and then I’m gonna be right back
so guys quick change of plan I decided to use some isopropyl alcohol instead of
the Arctic Clean to clean up the surface I mean – super clean surface and as you
can see it there’s no thermal compound anywhere to see anymore it looks like
brand spanking new and also here the heat spreader I clean this up as well
and there’s no compound residue left so let’s install this into the Mac Pro and
yeah obviously all we need for that is to quickly take the cover off that
should be a familiar process right now anyhow guys if you are new to my channel
and you to this tutorial series like I like I said in the beginning this is the
memory upgrade either previously this is the graphics card update and here we
have the one terabyte solid-state disk drive from Samsung that has the
sata 3 speed and so far I’m really loving the system especially because this
graphics card only draws a max of 75 watts power and the CPU that I’m
currently having in there the four core draws I believe up to 130 so I tested
this when I run the system under load it’s consuming about 200 watts of power
and yeah obviously upgrading the CPU to a more energy-efficient one will drop
that even further down all while giving me six cores instead of four and higher
clock speed so it may not be the super fastest system and it may not be able to
compete with the newest Mac Pro but still it’s a great value if you
remember these memory modules I got them for about 80 bucks and it’s 24 gigs if
you look what you have to pay for 24 gigs in a brand-new iMac you probably
know it’s gonna cost way more than 80 bucks so but I digress let’s pull out
the sport and then I’m gonna show you a shot from the top how I remove this
heatsink and yeah guys before we can start removing this heatsink obviously
you need I believe three millimeter hex screwdriver
did you call this screwdriver and I just take this out real quick and yeah you
may have to make sure that it’s a long one so if you were on the dual processor
system you gotta be careful because like I told you earlier the dual processor
system the four point on the Mac Pro 4.1 I think has delidded CPUs so you have
just the CPU right there here it should be fine and there should be a bracket
holder in there but let’s just remove this and I’m gonna show you how it looks like
so guys that was fairly easy I remove the heatsink
and yeah it looks pretty good as you can see here really it’s like a really real
mounting tray and that’s really the good thing that’s something you want to pay
attention to whether you’re Mac Pro has like a CPU mounting tray or how do you call this
bracket carefully remove the old CPU and yeah this CPU is like way more energy
hungry maybe I can give you a little bit of a close-up shot put the heatsink to
the side move this a little bit more in the center zoom in for you a little bit here
so you can see how a board like that looks when you look look at it from the
form a close-up shot and basically from all I can tell if I
operate my Mac just normally like if it’s just idling currently it’s
consuming about like a hundred watt and I think if I install the new CPU that’s
gonna drop and like I told you before under load it consumes like about 200
watts so I’m also gonna drop this because I think I wrote this down you
somewhere the the new processor consumes tops 90 watts
and has six cores and two old one has only four cores and a lower clock speed
and 130 so that should really make my system not only faster but way more
energy efficient so let’s take this out here real quick and put in the new CPU and
I’m gonna show you a trick how to apply the thermal paste and by the way guys
I’m using this MX-4 thermal compound and I believe that this has a durability
a rated durability of about 8 years so you can imagine this is a nine year old
Mac Pro so the performance of the thermal paste may or may or may not
degrade over time so it’s really good maintenance to clean out a little bit of
dust that’s here under the I think you call this ICH or IOH i always see this
can also get pretty warm because if you look at the at the Intel block sheet the
diagram of how the data flows I think there’s a lot of data flowing through
here but in any case I digress let’s just put in a new CPU and yeah guys as
you can see I really prepped the surface really really nicely so maybe I gonna
show this to you it really looks so super clean almost like a mirror you can
see like the reflections but yeah guys I digress so the important part is how you
apply the thermal compound because I looked this up in the Apple technicians
guide you have to remember that the processor unit below the heat spreader
is is shaped like this so when you apply the thermal compound maybe you also want
to apply it like in a line in this particular direction
from here to here not not sideways so that’s what I’m gonna do right now so I
hope this is the correct amount it’s always a little bit tricky you don’t
want use too little you don’t want to use too much obviously you don’t want it
to be so much that it’s like overflowing all over the place that’s not good
either but I did it sort of like it was displayed in a technicians guide
I hope it’s correct so let’s try this out put the cooler back on so guys success
I carefully put the heatsink back on while at the same time looking at the
Apple technicians manual for my Mac Pro and basically what it recommended is using a
crisscross pattern to do a few turns here then here so again this would be
one two three four five and maybe start with only two turns one two three four
five and then do another four turns one two three four five and the wording that
Apple uses in the technician manual is hand tight so that to me means when you
put this hex screw in and you carefully turn it let’s say with one finger then
at some point there is going to be resistance and right now you know I
cannot turn it anymore so you will feel the resistance so just like make sure
you use this crisscross pattern one two three four five and don’t turn on one
corner all the way down right away maybe just do do it like two or three times so
that you’re gradually lowering it so that it’s not like imbalanced one side is
lower and one is higher that way it’s it’s gonna be very easy to put this back
on so next up I’m just gonna slide the board back in and yeah I mean like I
really love these Mac Pros because like just look at how it’s designed that’s
such a such a futuristic state-of-the-art quality industrial
design um I think I’m not really sure why Apple stopped producing mac pros
like this actually I’m a little bit sad about it why not make a new Mac Pro
that looks like this but with the up-to-date hardware that wouldn’t be too
bad and yeah essentially even this tray it
has these guide rails so you can just slide it in how awesome is that for
maintenance you can access everything easily the drive bays your components
and slide in the processor tray in the memory it’s it’s really ingenious design
and you can really look at the details if you already have a Mac Pro or when
you buy one if you don’t have one yet and notice all these little details so
they’ve really tried really really hard to make this like a special machine so now that that is back on let’s put
the panel back on and I’m like guys I’m really nervous right now
I really hope everything works fine I forgot someone recommended not to put
the panel back on but to leave it open on your desk and then to see whether the
CPU light comes on so let’s let’s do it that way I think that’s better actually
yes you can imagine I’m super nervous I hope everything worked fine in just a
second I’m gonna push that one button and I really hope that it works
correctly so let’s check this out and yeah guys as you can see how I’m
really really nervous so let’s check it out moment of truth and I’m surprised it
took a second long a little bit longer than I’m used to but as you can see
there is no red check CPU light and the display came on just fine so let’s maybe
jump to the desktop and run a few speed tests so guys in fact I have used my
upgraded Mac Pro for quite some time a funny thing happened the despite the
fact that I have the early 2009 Mac Pro you can see it detected as a mid 2012
because I upgraded the CPU which is kind of funny so basically what I did I used
it for a while I run a total of the benchmark three times with different
configurations with the old CPU with the new CPU and the upgraded memory at the
slower speeds 1066 I believe and then with the PRAM rest it detected the
full memory speed so I’m just gonna quickly show you the test that I saved
in my geek bench account and as you can see the performance in and of itself
when you buy like this four hundred five hundred dollar Mac Pro used from eBay
with the Xeon W3520 CPU was about 8000 after upgrading the CPU to the Xeon
X5675 which is the server type CPU we are reaching almost 1400 oh excuse me
14000 so all I can say it’s like I really feel the performance increase if
I run apps if I export video and I think the most noticeable thing is really that
this Xeon X series CPUs they don’t seem to get nearly as hot as the W
series so let’s quickly go over the performance review that’s the basically
the most that I could get out of the system
for me that’s perfectly fine some people might opt and get like the dual CPU
system which i think is personally it’s a little bit overkill so maybe let’s
just quickly scroll down here I mean like you can you can look up similar
similar tests online on the Geekbench browser so maybe that’s not
that interesting maybe more interesting is to you to explain why this CPU is
really faster despite that and okay this has four cores and this has six cores
and guys maybe you see already I have to stop the recording for a moment and do
some digging but what I found is a really really good explanation and I
hope this shows when I compare these both to CPUs and their characteristics
site by site I mean the first thing that you can already notice is Intels
website is a great tool if you’re planning any CPU upgrade if you plan to buy
or purchase a old CPU make sure you do a little bit of research before you do
so you can see that this old CPU has a lower data transfer lower clock speed
and only four cores versus six cores down here and this is like immediately
reflected in the price like the old CPU was considerably more affordable than
the more expensive server kind of grade CPU so basically the W designation are
from what I understood is like more workstation and the X designates it as a
server product although it says here server on both so for me the W is more
like a workstation now when I looked at the performance listing here one thing that
I personally noticed at first was that the new CPU despite having six cores
draws significantly less power and a second thing that really caught my
attention was looking at the memory specifications and granted I did this is
a little little bit after the fact because I just curiously I wanted to understand
why is the CPU making my system so much faster and one explanation is simply if
you look at the maximum memory bandwidth I mean I put in 24 gigs of memory so
this quite a lot of data when I edit video so increasing the memory bandwidth
from 25.6 to 32 was really significant and basically the way that is done is
that both these Intel CPUs the W3520 and the X5675 they both have what I
understand it build a memory controller and this more expensive CPU over here
can address ginormous amounts of memory I’m probably never gonna put that much
memory into my system I think the max I can put in is 48 or 64 but I said this
earlier in my memory video this the CPU has basically both CPUs have a three
channel memory controller the difference is that this more expensive one can also
run the memory at a faster speed and basically what that means at least from
my understanding and what I could research is that you get different data
rates based on the frequency the megahertz frequency your memory runs at
so I maybe I can quickly show you this in a calculation because here in the
table it’s not as obvious but yeah looking at it here I’ve written this
down and 100 at 1066 you basically get a data transfer rate of 8.5 gigs that’s my
understanding I mean please correct me if I’m wrong I am I don’t know all the
answers but from what I can see it appears to get three
8.5 gigs times 3 it gives you exactly the 25 gigabytes per second that we
could see over here it’s the maximum memory bandwidth so yeah and then
obviously it’s logical if you have a bigger CPU a bigger CPU a more
powerful CPU like the X5675 then yes surprise surprise if you run the memory
at the max speed which is now faster than the old CPU you get a bigger memory
bandwidth so each ddr3 memory module can now
deliver 10 point 6 gigabytes per second multiplied by a whoops by 3 the number
of channels you get a higher data rate so that I feel really contributes to the
fact that when I use the system for video editing it’s just it can just suck
up all this data from the solid state disk drive dump it into the memory and the
CPU can access this really fast with bigger data transfer rates
and that results in a really really super fluid system only thing that I
noticed you really need to make sure that when you upgrade the CPU and when
you upgrade the memory that obviously if the previous CPU would would be able to
address 24 gigs but the previous CPU from my understanding would not be able
to address the 48 gigabytes so if you had 16 gigabyte sticks you would have 48
and total that you can only do with one of these more modern CPUs and then to
get the full speed I also had to do the PRAM reset because once I the
memory I put in first with the old CPU then I upgraded the CPU but the speed
would still stay at the lower speed so not utilizing the full memory bandwidth
that the CPU can carry and the modules can deliver so and I saw actually I saw
that in the forum’s people say like wow I have the right CPU I have the right
memory why is the speed not at this 1333 megahertz well the answer is because you
should to the PRAM reset and then it should
work just fine so guys I really digress um that should sort of conclude my
tutorial series of how to get the most out of your Mac Pro 4.1 and 5.1
and I think I have sufficiently answer the question whether it’s worth to buy
an old Mac Pro from 2009 as I’ve shown you it’s really possible to work with
these machines in 2018 and beyond and just a quick recap maybe I can show this
in the navigation here below you just have watched part 6 if that’s the first
video that you watched you may also want to consider making sure you have looked
at each of these individual videos I had a basically I had an introduction of the
project then I showed you the Bluetooth fix I showed you how to install High Sierra
on the unsupported Mac Pro 4.1 I showed you how to do the firmware
update I showed you how to create like this installation medium that you have
high sierra on USB stick you don’t have to download it each and every time you
do system your installation I also showed you how to use a one terabyte
solid-state disk drive while getting the full speed out of it with this adapter I
showed you I told you a lot about graphics card I showed you how watch
what graphics card I pick what performance I got out of it which other
faster models you can use I told you everything about memory and the pitfalls
how to choose the right memory what to consider what my experience was and I
finally showed you in this video the CPU now should they still be for some
mysterious reason unanswered question about the Mac Pro 4.1 and 5.1
then maybe just use the spot in the navigation and leave it under the
corresponding video if it’s something about graphics cards post below in a
graphics card section or if it’s about memory in the memory section I’m really
curious what you guys think about this tutorial series it’s the
first lengthy tutorial series I produced previously I always did more like a
shorter standalone things like for the iMac for example maybe I can show this
to you here the iMac tutorial that I did where obviously you have to be a little
bit careful with the power supply the only thing I could not think about is
maybe how to do a fan replacement in the Mac Pro because I noticed my
power supply fan is a little bit on a noisy side so I actually I looked at how
to fix the fan on the Mac Pro maybe replace it with a Noctua fan
because they’re supposedly are so quiet but it’s a little bit of a tricky job
because the way the cable is routed but ya guy said let me know in the comments
below if you want to see a video of how to make your Mac Pro quieter if the Mac
Pro if your Mac Pro is so loud that the fans are loud I mean obviously if you
have a computer from 2009 the fans have run for nine years so it is
understandable that they might become a little bit noisier over time and it
would be for me personally it would be interesting because I like super quiet
computers so obviously the Mac Pro it’s a big machine so it’s not super super
quiet but I also don’t find it very very noisy so that concludes this video I see
as a subscribe on my channel all the best to you take care and yeah guys now stay
tuned for the secret follow-up episode where I show you how to make your Mac
Pro’s fans much more silent or how to replace the fans and with the Noctua
fans so more and more people have already subscribed to my channel because
of the useful content that I produce and if you also want to learn how to become
successful online then I see you as a subscriber on my channel or in one of my
online courses all the best to you take care
