Fixing stuff, myself included…

2009 Mac Pro 8-Core to 12-Core

What? Seriously? I thought you were happy with what you had.

Yes, delidding and all that frightening stuff. The 2009 Mac Pro 8-Core is the only Mac Pro that shipped with delidded processors. I couldn’t resist an 8-Core on Ebay for $227 with local pickup.

What the hell is delidding?

The integrated heat spreader/sink (IHS) is removed from the chip. Overclockers are familiar with this processes. However, what makes it more difficult is the particular Intel Xeon in the 2009 are soldered to the chip; it’s not just thermal paste. There are various methods on the internet, ranging from a using a vice to “pop” it off, to a small torch applied directly in the chip area of the IHS. After watching lots of videos on youtube, I did it using a hot air station. It took longer than 30 seconds, more like a minute. The temperature was at 400 C.

So it “went off” without a problem?

Not really…

Okay, do tell… what the hell happened? 

Well I didn’t burn the house down, but I started off with the wrong  CPUs (kind of like starting on the wrong foot). which I didn’t find out were wrong until trying to boot the machine. Both CPUs delidded  and solder cleaned from the chip, thermal paste applied, both heat sinks tightened and press the power button = chime then kernel panic.

Oh no! Now what?

Remove heatsink B and CPU in B socket and boot with only new CPU in A socket = capable of boot. Sooooo remove heatsink and CPU in A socket and put in the CPU removed from B socket = second CPU in A socket also capable of booting. Put both back in respective sockets (reapply thermal paste), press power button = chime then kernel panic related to CPU again!

So what’s up? 😡

Well, according to Macrumors, I’d gotten the wrong CPUs. The Xeons that begin with a W are fine for the single processor 2009 Mac Pro, but not the dual processor 2009. The dual system requires the Xeons that begin with an X.

OMG what did you pay for those little bastards?

🙁 $85 for both and now I have to get the X Xeons. So I listed the delidded CPUs on Craigslist, and ordered what I should have gotten in the first place. Lesson = you can never do too much research before beginning a new project. Took a couple of days for the correct processors (X5675 @ 3.06GHz) to arrive. Since I already had two successful delid experiences under my belt, this time it went off without a hitch. Yeah, I maintained my balance without dropping a shoe.

 

Waiting For The Latest…

Not a Joke

Words do matter. Facts Matter.

Almost 80 Years Later…

Oh no, it’s not time travel again, is it? 

No, time travel would be much easier to talk about.

So about 80 years ago, was World War II. Why talk about that now? 

I watched the movie, “The Pianist” yesterday. Set in the Warsaw ghetto, = witness the survival of the Jewish pianist against all odds. The cruelty and death in the ghetto foreshadow our world today. As I watched, I just kept thinking/feeling, the horror over and over, the horror. And so in 80 years only the targets of hate and fear have changed. Muslims, Syrians, refugees, people from “shithole” countries are not welcome here. Many Syrian cities are rubble. Those who can get out are fleeing, some with nothing more then the clothes they are wearing. Just as we stood by while Hitler and his henchmen murdered the Jews, we have done little to stop Bashar al Assad from murdering innocents. The world is still a dark place for so many. I can’t say anymore about it.

Why not?

It’s so terrible; in truth it was very hard to watch the movie. I had to watch, I think we all should be reminded not to forget history. Although it’s in the history books (except holocaust deniers), it doesn’t seem we learned how to avoid being cruel and hateful human beings.

 

 

Now What?

Yeah, that’s right now what? You’ve got the “machine” all tricked out; what you gonna do with all that power?

Going back to some tutorials for Blender. I was making progress last spring, before my dad went on the downhill slide. Too much time has gone by for this old mind, and I’ll have to begin again! Downloaded the current version yesterday, and so begins the play.

 

Geekbench Scores

Geekbench sees my 2009 Mac Pro as a 2010, because of the firmware hack. More than satisfied with this machine as it stands now.

CPU Replace = Success!

So… how did it go?

Not too scary. The new/refurbished 6-Core processor arrived yesterday, and I put it in the Mac Pro today.  The Northbridge heatsink is under the the giant processor heatsink, and the plastic rivets on it the were holding fine. The sink was; however, full of dust; a good blow out with compressed air has the Northbridge Chip running 10C cooler! With not much going on the chip reads 53c instead of 63c.

What about the Geekbench results on the cpu?

The multi-core score did almost double and the single-core rose somewhat. I’ll post the particulars tomorrow.

Stuck…

Yes, I’m stuck trying to implement a jQuery toggle for comments. Unless you want to leave a comment, you shouldn’t have to see that form under every post! Had plumbers in the house all day; spent a lot of time trying to figure out comments.

So did you get it done?

Plumbing work got done, but I gave up, after fiddling for hours with various scripts for making comments act the way I wanted them to. Removed the numerous changes I made in several files, and now have no comments. That’s fine.

Whew… lots of WORK to do
Broken links, irrelevant links, linked blogs that have disappeared, software that is way outdated, missing flash files. Where the hell are they?

Ha I knew you couldn’t resist asking a question.

So where do we go from here?

Waiting for New/Old Refurbished 6-Core CPU

So which one did you get? 

I got an Intel Xeon W3680

6-Core

Hex Core 3.33GHz LGA1366 Processor on Ebay for $77.00. Already have a long hex screw driver for removing the heatsink, from working on the Northbridge sink in my 2008  Mac Pro (MP)3,1. Previously I noticed via Hardware Monitor, the Northbridge Chip in the 2009 MP5,1 seemed to be running hotter (68c) than it should at an ambient temp in low to med 20s Celsius. So I was planning on removing the processor heatsink anyway, to check on the plastic clips that hold the Northbridge heatsink which is under the processor heatsink. If I am removing the processor heatsink, I figured I might as well go for the processor replacement at the same time.

Hmmm, that’s some gobbledegook if you ask me? 

Nobody’s asking you! Remember you’re the one who asks questions, not the one who answers. The “gobbledegook” is for my record, of what I hopefully can accomplish without any mistakes.

Geekbench scores before the switch: 

single-core = 2513 and multi-core = 8601 and openCL = 16147

The big difference should come on the multi-core score; it should nearly double. Little to no difference will occur  on the single-core or the openCL score, because it still testing one core for single, and the video card, which is the openCL score will be the same (ATI Radeon HD 5870 1 GB) Won’t have any results till next week when I make the switch. Fingers crossed!

By the way if you click on the cpu photo, you can see the metal casing/lid I was referring to in the February 8th post. De-lidding is the removal of the casing via heat to reveal the naked processor.
