2006 mac pro CPU upgrade: where can i get...

[Sweetfeld28]

Thanks for the info.


Well, my order fell through for the X5365's. The company I bought them from just sent a email stating that they sold out of them, and won't be reordering them.

So, I jumped on eBay, and bought 2 of the X5355's [SLAEG (G0)] instead for $300. They are used pulls from servers, so I'm hoping they don't have any issues.

Update

Ok guys, I updated my processors yesterday, and so far have been running without any issues.


I did want to ask however, what are your temps at during normal usage? I just noticed that with the Quad 2.0 my temps were in the mid to upper 80's on both processors.

Now, with the Octo 2.66 setup, my temps seem to be around 86 on processor A, and 90 on processor B. When under full load while folding@home, temps are in the 110-120's range. I'm just wondering if i'm in the normal range, as far as temps are concerned?

Unless those are Celsius values you should be absolutely fine.

X5355 running at 35ºC (94ºF) so you are okay.

They are actually Fahrenheit measurements. Here are my temps, as of right now from iStat Pro.


Thanks for the input guys.

Thanks for the videos.


I'm a little late to this whole thing of upgrading my 2.0 MP, but I just wanted to ask some questions before going a head and buying my processors.


1. Has anyone upgraded to the X5365 Xeons running at 3 GHz? I just recently found these pretty cheap, and am considering buying a matched pair for around $500.

2. Has anyone ran into issues besides running hotter?


Hopefully this will revive an old thread, and maybe some people could share the performance they have had since doing the upgrade.

I have a 2006/2007 Mac Pro (build date Sep 2007) that came with 3.0ghz 5160s, I replaced them with 5365s last Monday and they're doing fine. Cost for the two processors was $500.00 including shipping.

Before the CPU swap the heat sink temps were: CPU A - 32ºC, CPU B - 30ºC, ambient temp was 23ºC. I had these temps by running the CPU/RAM cooling fan at 1000 rpm, which is not very noisy and I like the notion of longer component life.

After the swap, with the cooling fan at the same rpm, the temps are: CPU A - 28ºC, CPU b - 27ºC, ambient 21ºC. I regard the smcFanControl app as a next to necessary addition to the whole computer longevity thing, it allows a lot of experimenting with temp control based on the environment in which you run your machine.

I also ran the ROM updater which enabled the CPUs to be recognized, now I have a Mac Pro 2,1 according to "About this Mac".

I flashed the firmware, and added the text to change the processor name; however neither of these changed the status of my MP 1,1 to being a 2,1. Anyone know why?

I'm upgrading the processors in my Mac Pro 1,1 to a Xeon 5160. I've been looking on eBay for a deal and I've seen ones that say "SLABS" and ones that say "SLAG9." What is the difference between the two? Does it matter which on I get?

In general, it doesn't matter. All steppings do work in 1.1, you can even mix them.
SLAG9 is latest stepping rev. and (according to some people here) it has little lower power consumption when idle.

Quoted from another thread. Interesting to me is the last part: I'm in a similar boat, could get a good deal on two X5365 3GHz QC for my MP 1,1 2.66. They have the SLA4P stepping though, instead of SLAED which should be also more desirable with regard to less power consumption from what I've read.

Is that correct, and could this be fixed – maybe flashing the MP's firmware to 2,1 would do the trick? Thanks.

Anyone familiar with the Clovertown series of Xeon CPUs?
