Upgrading Mac Pro CPU

Damn! Just got an email from the vendor saying they're out of stock but at the time of purchase they had plenty !?

Uuuurgh

EDIT: They do have the X5355 (2.66) but for the sake of an extra £60, i'm thinking i should wait for the X5365 to come back into stock. What do y'all think?

E5472 = 3.0GHz
X5472 = 3.0GHz
X5482 = 3.2GHz
X5492 = 3.4GHz (untested AFAIK)

All of the above parts have a 1600MHz FSB, which is one of the major advantages the Harpertowns had over previous systems.

X parts use more power than their E cousins.

I have the 2x2.8ghz cpus on my mp3,1, ive been told instead of upgrading the cpu just put more ram and update the video card, will that boost performance more than the cpu?

I just bought this MP used last week. Geekbench shows 10700 for it. HAs 2gb ram and ill be adding another 2gb to quad it.

If maybe new cpus are way to go, where would u buy them and can I upgrade them myself?
 
cpnotebook80, your situation is different. you already have 2 quad-core processors. The original poster wants to upgrade from 2 dual-core processors to 2 quad-core processors. cpnotebook80, adding extra RAM, I would recommend buying four 2BG sticks. That should give you a huge performance help coming from 2GB total.

villlagemusicman, for the price difference, if you can verify that the 5365s will be back in stock in the foreseeable future, I would wait for them.

Hi, I own a MacPro 1.1 (2 x 2.66 Ghz dual-core Intel Xeon) and am thinking about buying two X5355's to make it into a 8 core machine. I've read positive remarks about the change. These chips go for around $430 each new.

I'm wondering about buying used. Do chips even go bad? Do they were out? Any other reasons to/not to buy used?

I'm also wondering about the tools needed to do the change. Are there any good standard toolkits available?

Thanks in advance!

Where do you even find these chips new? I have been looking everywhere and have been unsuccessful. The few ebay auctions I have been involved in always ends up with someone jacking the bid like crazy in the last 2 minutes...i suspect the seller is out there doing this to raise the price. If there is a legit seller out there for these 5355 or 5365 chips I would pick them up to revitalize my 1,1.

On that point, I had put the 1,1 up for sale and received an offer from a guy in Nigeria willing to pay for shipping. It sounds awfully dodgy.
 
Replacing CPU's in Mac Pro 1,1 with E5345

I purchased from bay 2x Intel Xeon E5345 Quad Core 2.33 GHz MATCHED PAIR CPU. They were Confidential Engineering Samples and one had the markings:

Intel Confidential
QWTW ES Costa Rica
imc '05 HH80563QJ0538M
3720A955 e4

The other had similar markings.

I used them to replace the original 2.66 GHz processors in my Mac Pro 1,1 (2006). Upon startup I got a "panic" the first line of which read:

panic (cpu B caller 0x295aab): "Should have 2 Cores, but only found 1 for Die 2"
@/SourceCache/xnu/xnu-1504.7.4/osfak / i386/cpu_threads.c:1118

Any suggestions????
 
Hi Dondog,

I have heard (I made be wrong) that X5355 & X53565 were the only two possible prossesor replacements.


Good luck
 
How to swap your CPU tutorial

Just posted part 1 of a 2 part video tutorial on how to swap the CPU in the 1st gen Mac Pro here:

http://youtu.be/wmz7gPw31L0

I should have part 2 up this week-end, but this will give you a good idea on the basics of what's involved and what to purchase before getting started.

Enjoy!
 
Anyone figure how to change processor type in Lion to show what they are?

Tried to edit the plist, but it is not changing.

Tried this with no joy. CPU Injector already shows that file and date, and Kext Utility runs, installs, repairs permissions etc but no change to Apple System profiler, still reads Processor 2.66GHz Unknown' even after reboot. Any suggestions please?
 
Doesn't matter whether you're on Lion or on SL. CPUInjector.kext works on both, I think.
Delete CPUInjector.kext from /System/Library/Extensions/
Reinstall it and check again.
 
MacPUID recognises processors as genuine Intel X5355 but does nothing to change 'About this Mac' in Apple System Profiler. There must be something changed in Lion to prevent these packaging updating "Processor 2.66GHz unknown' to 'Processors 2.66GHz Intel Xeon Quad Core X5355'.

Apple System profiler under Lion is completely utility different to Snow Leopard etc.
 
Its really strange, I have the same CPU and mine is all ok. You dragged the CPUinjector.kext into the kext utility?

I had to reboot as well

Send them back and get non ES chips. The mac pro's require particular stepping (ie B1). I know 2.33 work as I did my old 2006 mac pro with them. Cant remember the stepping though.
