Hey guys, it's Lance at McV Audio and today I'm gonna be installing
new CPUs into my
2009 Mac Pro 8 Core 2 point 2 6 gigahertz. I'm gonna be installing
5650
Xeon on 6 core
2.66 processors which will be upgrading me from a
2009 nellaheim to a
2010
Westmere
12 core from 8 cores to 12 cores, and here's a list of the tools you'll need to do the surgery
Just pause the video to get a longer look
The other thing that I have already done is the firmware update which you have to do before you put in the processors
This will also allow you to use faster RAM
Instead of the 106 6 you can now use 1 3 3 3
Anyway, I'm extremely nervous about this install. You are witnessing me before the surgery and
I've seen a lot of people do this successfully
And I've seen a lot of failures it takes us that he had because if you touch the side
Failures can prove to be extremely costly
You can ruin the processors. You can ruin the logic board or you can ruin both
It's more involved with the 2009 because the chips do not have the integrated heat spreader cover on them
So when you put new chips in there's a 2 millimeter difference between the original
Processor that's in there and any replacement you're gonna put in there
Because of the little silver cap on the processor, so that means things have to be done slightly differently
2010 you can just pop in the CPU and
Basically you're done. It's much easier, but 2009 is trickier, but the cost
Factor is much better
Basically, you can get the 2009 a lot cheaper than a 2010 and then you can upgrade it with used chips
I bought used chips on eBay. So there's another thing that could go wrong. I could have bought a bad chip
so
Here we go. I'm going to video it in high-speed. I'll see on the other end, hopefully
successfully with a big smile on my face
Otherwise, you might see me crying, which I really don't want you to see so stay tuned and keep watching
Its operation the wacky doctors game where you're the wacky doctor
okay, so here's our patient and
The first thing I do is remove all the RAM
From the logic board just to get it out of the way, basically
So you can see that I put tape on top of the
Heatsinks and then I just labeled them because you want to know which one is a and which one is B
They are not shaped the same
so you got to put a back in the a slot and be back in the B slot then what I'm doing is
marking the amount of
rotations it takes to
unscrew one of the screws in the heatsink and those heat sinks are
Spring-loaded the screws rather so they don't
Pop out or fall out they stay in there and then I put the hex key in and found
exactly where it locks into the screw and then I mark the tape so I knew exactly
Where I started unscrewing the screw and when you get to the end, you'll know it because you'll hear the screw click
Which means you've unscrewed it all the way they don't rise up out of the heatsink
So it was about nine and a half full rotations to unscrew each screw
Then you want to pull straight up as you pull the heatsink off and then I slowly
Twisted the processor which is stuck to the bottom of the heatsink off the heatsink and then clean the area with rubbing alcohol
and a lint free cloth and
Now what I'm doing is fumbling with a little black connector
basically
You need to remove the heatsink
Cable from its housing and then you want to cut off the black plastic tabs that keep it in the housing
So when you go to reconnect the cable back to the logic board
You push it up through the hole and it'll give you a little slack to make sure the connector is all the way in
now you may be able to get away without doing this, but it ensures that it makes
proper connection back to the logic board when you put the heatsink back on and the reason you do this is because the
Cpus are thicker than the originals and if the heatsink cable doesn't make full contact
With its connector on the logic board your fans are gonna blow at full speed and you're gonna have to remove the heatsink
Remove the CPU and start all over again and never try and put the heatsink back in when the CPU
Is stuck to the bottom of it, you have to take off a CPU clean it off
Put it back in the CPU socket put on new thermal paste
So I think it's a safer bet to do it this way
Then the next thing I did was put the mopeds on the heat sensors each CPU has its own heat sensors
So they're not exactly the same size
So CPU a you cut a piece of the thermal pad to fit
CPU a heat sensors and then do the same for CPU B
You can see CPU B is a thinner strip and the heat sinks already have thermal pads on them
But we need to add this in addition to them to make up for the difference in the CPU size
Okay, so now I'm inserting the first CPU
the one thing you have to do is make sure there's little to nukes on either side of the
CPU that have to line up with two little posts in the socket
Now I'm applying the thermal paste
I went with a method I saw a guy do on YouTube which is just to put like a pea sized
ball in the very center of the CPU
I didn't spread the thermal paste around like a lot of people do like it's frosting on a cake
I just used this method and the heatsink spreads it around onto the CPU
This is the trickiest part which is to reinsert the now loose cable from the heatsink to the logic board
it was not easy connect the cable first to the logic board and then guide the heatsink straight down on top of the
CPU so I
Reinserted the connector to the logic board from the heatsink and then I guided down the heatsink straight down unto the CPU gently
So here's a better look at the bottom of the heatsink and the loose connector
See how the loose connectors coming up through the channel now
That's the way you want it and then you have to put the wire back into the channel before you
Reinsert the heatsink, and now I'm adding another
Pea-sized drop of thermal paste onto the second processor and then I'm going to reinsert the connector first
So I get the connector in there it clicked in very nicely and then I'm gonna guide down the heatsink nice and slow on
top of the CPU
Okay, so here's the critical part of this operation which is to not over screw the heat sinks when you put them back in
And count the amount of turns that you've done as you put them back in it took about
3.5 turns on each screw till I started feeling a little bit of pressure
and I went with that for starters even though I think in the end, it's gonna be more like
4.5 turns
because you don't want to over screw them in if you over screw them in you can crush the
CPU and the logic board and all the pins on there
Ok thumbs up fingers crossed the operation she is done ok kids
Please
Please let it work. I
Have to say it's pretty nerve-wracking because there's a lot of variables. So if something goes wrong
You're not really going to know what it is
It could not be enough pressure down on the CPU could not be enough thermal paste
The little connectors that go from the motherboard into the heat sinks
so here you're gonna see my response my reaction to whether this baby is going to be a 12 core or a
No core
Please let it be a 12 core here goes it's a tea bag don't get nervous. There's the power button really scared
I'm really scared
Fans are dying down. That's a good sign. I don't know power light is flashing
We're a no-go
Well after tightening down the heatsinks another
quarter turn half turn each
She boots
But there's one problem one RAM
Chip was not showing up and slot two of eight slots. I did it. That's
$200 I'm smiling now because after a few more turns of the heatsink on the first CPU
all
Channels of memory came up. So now we got eight gigs of ram in there, which is the older Ram
I'll be putting 32 gigs ram in there
Whoo?
I'm glad it's over it took me probably two hours
all together because I was very careful and
It's really tricky
I don't think I recommend it unless you really have the balls to go for it because it's and you got to read up and
Read up and read again
Because if you over tighten those CPU screws, you're gonna kill everything your CPUs and your logic board
It takes a steady hand because if you touch the side
So anyway, thanks for tuning in
See on the next McVie audio video
Operation again for milking badly
You
