The POWER5 MCM you are showing here has four CPUs and four L3 caches with anywhere from 36MB to 144MB each. A single POWER5 CPU has two cores and two independent L2 caches. The number on the side of the MCM is actually the serial number. The green coating on the cache chips is actually a passivation coating, something other than the silicon nitride more commonly used for passivation; I wouldn't know why they would had used a different passivation material. That MCM has 4,491 signal I/Os and the CPUs have 89 metal layers.
Impressive build and teardown, as usual on this channel! What I'm still left wondering is how the ceramic substrate for the eight dies is constructed. The dies seem to be flip-chipped, but are they soldered or glued? And how is such a massive ceramic substrate made? Would be interesting to see a cross-section of it under a microscope...
I wouldn't mind having a POWER5 system one of these days; around the last couple years of production of the POWER5 line they made some workstations based around one or two CPUs which ran either AIX or Windows NT.
It would be interesting to see the power supply from these servers, also the connections from the PSU to the processor. The Z9 had a lot of capacitors on the mainboard, on this one I didn't see.
I love the mainframe videos, they are astonishing :) A quick question: what are those 3 huge contacts (seen at the left) at 10:21 ? are they power connectors for the book ? thanks.
If I remember right, these are the power contacts to the CPU power converter. 1.5 Volts and a hundreds of amps. There are also other power contacts but they can't be seen so well.
It's a Multiplexer (MUX) card: www.ibm.com/support/knowledgecenter/en/POWER5/iphau_p5/partssystem.htm#partssystem__partssystem_memory. I guess like a multichannel bus controller.
Wow man, there are some bucks in copper and aluminum in there... You should start storing these... And is really cool to play with magnets if you got copper that thick :p
Omega Speedmaster Automatic.... not the watch Dr.Forbin wore but almost the model of the Apollo 11 astronauts. Did you know they're planning a "Colossus-Forbin Project" remake? With Will Smith? I bet that will get awful..... It's one of my favourite SciFi movies.
@@PlaywithJunk Dr Forbin wore a speedmaster? I did not know that. In fact I have a speed master. If you give me your email I'll email a pic of it. As for remake. Leave it alone. The remakes only show how out of ideas Hollywood is.
we had them as spare machines for our customers. Customer kicked them out and we didn't need them anymore. There is no market for 10 year old systems of this kind. It is more work than income if you try to sell them.
At first, I was disappointed because , to me, "IBM Mainframe" means old 360s, 370s and stuff like that. But after few seconds watching this I was dissapointed no more because these put the "big" into "big iron".

That's what I call useful information.... thanks!
I keep coming back to your videos because there's nothing like these servers today. The spare-no-expense build quality is so impressive.
Watching your videos is like a drug or unwrapping a Christmas present when I was a child.

What do you think how I feel when I disassemble that thing...? :-) :-)
Old computers like these are such a piece of exotics stuffs they are valuable even as they are decommissioned
Very interesting, very rare that us normal people get to see inside these machines. Thanks again!
I wonder so much about mainframes. Thanks for this look into what's inside!
I must tell you Sir that I am very jealous of you for having access to such interesting equipment to disassemble. Good job on the videos!

fascinating.. what kind of company are you working at ? is it like specialized on recycling computer hardware ?
Wo sind die CPU's denn hin gekommen?
have you ever seen one fully loaded with 4 books maxed out on everything? how powerful it is?
Thats a nice Power5! Where do you find all this staff?
+chrigel1234 Do you still have one of these CPU chip's left? I realy would love to buy one!
Hi, what a beauty of CPU, is there any posibility to donate me such a thing if those equipments are disposable? Regards!
write ma at playwithjunk@gmail.com ...I'm sure Ican do something for you :-)
that middle card might be the voltage regulator for the ram
+Cpt. Snow No, no switching devices are on that board, neither inductors.
+Gatea Catalin I've just barely noticed two chips there which looked like some Altera FPGAs...

This is the kind of job I'd love to do
Is that at your work? If so it looks like a dream job!
+Jay Walt
My job is actually to repair stuff like that... and sometimes we have to clean up our stock.
Fajną macie zabawe.
Don't people collect those machines for museums?
+Coolkeys2009
Some do... but to ship that ton of material anywhere you have to invest some $$$. Nobody wants to pay much.
@@PlaywithJunk Sad that EMP in Seattle and Other History of Industry Museums can not get more funding, to move, display and store some of these units.
Wow man, there are some bucks in copper and aluminum in there... You should start storing these...
And is really cool to play with magnets if you got copper that thick :p
I can find even bigger bucks for aluminum just by crushing aluminum cans. There's so many of them.
I bet just the waste heat would keep a multi-story office building warm in winter.
What kinda of watch to do have on your arm?

@@PlaywithJunk You In Deutschland or Switzerland?
I wrote NOT the watch Forbin wore... I just wanted to point out that I know what your logo and name means :-) btw: Switzerland
@@PlaywithJunk One of my best friends is from Switzerland. Wonderful place. Not like shithole U.S. What watch did DrFlorbin wear?
Beautiful chip :)
Das wäre ein Traum wenn ich so was geiles an Technik auch mal zerlegen könnte.
You can film in your work ?
Yes, why not? We are not the CIA :-)
Part 2?
-> PWJ33 is part two
it seems 7744 pins per module
Hi there how do get these mainframes ?
You must make alot of money from these ?
we had them as spare machines for our customers. Customer kicked them out and we didn't need them anymore. There is no market for 10 year old systems of this kind. It is more work than income if you try to sell them.
Echt geiles teil😍
i would be very interested in the chip. and i could come and pick it up as i am based in zurich. name a prize. 😃

Mainframes are still mainframes :-)
Skookum build quality.
I bet you were secretly saying 'focus you fack' too? Lol
IBM knows how to collect extra cash...
