Building a MacPro, Yes, a MacPro not a Hackintosh Options

[nagal]

Get this book and check out www.osxbook.com . The author is brilliant.

I just spent $782 on a logic board, I can barely afford to breathe right now let alone buy a book It does look like a good book though.

Early 2008 Mac Pro still ship with ATA 133/EIDE Superdrives ( Sony, Optiarc, Pioneer ). It has the same 6 SATA as the older MP's, 4 HDD 2 ODD.

New logic board in. Some success...





I am a bit baffled as to why the CPUs still are reading 2.13 GHz @ 1066 FSB. They are the correct engineering samples for 2.4 GHz and they are BSEL modded. They should be showing up as 3.0 GHz @ 1333 FSB.

I have not tested the Apple fans to see if they still run @ full speed, that will be next.

That was extremely fast! Nice...which revision of the logic board is this again? Can't wait to see the bench results as well

[nagal]

Fans still run fullspeed due to the thermal sensors I got not working. I wonder what kind of sensors Apple used.

Here are the Geekbench scores. No idea if they are good but I assume they are good for an 8 core 2.13 GHz machine. I am going to tear everything down again tomorrow and re-apply the BSEL mod.

Nagal, you may want to run MacCPUID to verify the actual processor profile and speed after you do your BSEL mod.

Yo yo yo... just stepped in after a wonderful night of band practice... well anyway... FRICKIN Awesome Nagal, you are fast. I'm also really spoofed at the fact that your board is showing up with a FSB frequency of 1.06Ghz. Logic Board Version 2. should have a FSB of 1.33Ghz; the former, probably due to your xeon's FSB forcing the logicboard down to 1.06Ghz? Your engineering sample has a FSB of 1.06Ghz right? Does system profiler register the Xeons specs from encoding on CPU or from actual computer calculations? My board is on it's way and once I get it all running I'll print my stats.

System profiler and other utilities read CPU_ID strings to show processor type and bus speed. To see actual speed after a BSEL mod a utility that calculates speed is required, such as MacCPUID.

GeekBench 2 is no more accurate than xBench 1.3 ( surprised ) my GB scores are all over the map ( low 7698, high 10122 )

Nagal has the installation of the new logic board fixed the firmware update problem? Can you now get updates from Apple?

Also I might be in contact with you soon via PM to see if the components I have in mind will all be compatible (the right board, processors, etc)

[nagal]

newtech,

Thanks for the link to MacCPUID. According to it, the BSEL mod is working as it reported a FSB of 1333. I am still curious as to what clock multiplier my CPUs are at. I think I will install Windows tonight and use CPU-Z to find out. I briefly looked into that sensor you listed but what I need to find out is what kind of sensor plugs into the jacks by the cpus. Its does not appear to be the typical temp sensor used in PCs as I have tried those and got nothing. As for Geekbench, someone asked for the scores only reason I posted them. I do not take much stock in Geekbench or Xbench either.

Kimosabe,

I still have no idea if I can get updates as the board came with the latest update it seems

digitalperformer,

cool your board is on the way! I did not have time to do any pinouts on the PSU wiring and looks like Saturday might be the soonest I get to that.

[newtech]

Nagal, here is an application note that may be the CPU sensor arrangement you are looking for. The two pin header(s) is the heatsink/CPU ambient sensor. The SMC sets fan speed based on output from sensors in each core and the heatsink/CPU ambient sensor or defaults to minimum speed stored in the SMC Firmware if below threshold temp. In the absence of a valid heatsink/CPU ambient input fans go to max.

Fam 6 Mod 15 stp 4 is an very early stepping for Clovertown that is like A2 or A3. B3 and C0 are the retail/producton steppings ( SL9xx=B3, SLAxx=C0 ).

[nagal]

Awesome info on the sensors! I am going to hunt down some 2N3904 diodes and hook them up and see what happens.

The cpus are ES so that explains the stepping

Yes I recall that you had ES processors, I was saying that is even a very early stepping for ES, scarcely beyond prototype.

Probably want MMB3904 or SMB3904 transistor if you are looking for reasonable thermal accuracy. T0-92 case 2N3904 likely has to much bulk to read accurately, base tab on surface mount component should be in direct contact with heatsink.

I agree about the T0-92 being too bulky. Mouser has MMB3904 at 3.2 cents each when you buy 10 or more but of course its going to be like $7 shipping and I have to wait till tomorrow to order them because I am so broke right now

[newtech]

Halted Specialties ( 3500 Ryder Ave Sunnyvale ) may have MMB3904 in stock. could be more like $0.50ea but no shipping if you buy in-store.

That would be awesome if it was local to me I'm in SoCal and where I live the only choice for electronic components is Radio Shack and that really isn't a choice. Even if I was to drive somewhere that had them, I'd spend more in fuel than what Mouser is going to charge to ship.

My bad, I forget I am at the center of the ( semiconductor ) Universe here in silicon valley.

BTW and OT

Boo to Intel for scheduling closesure of their last chip fab in the USA ( Santa Clara ) ( I ran fire alarm in the DI water plant and HQ 4 years ago and Ethernet adds in the fab 2 years ago )

Don't apologize for being in Silicon Valley must be nice! and yes boo to Intel!

It would have been nice if IBM and Motorola kept it together for Apple and really crafted their PowerPC Chips to greater heights. Ohh well... I would love to see Gate's face when Jobs unveils the official Mac OS X - lock free. I predict Microsoft will lose 50 percent of their market share within 8 to 12 months. Anyway, good news, talked to the guys at applepalace... package to arrive monday. Logic board, PS, and card risers. The rest from newegg... two quad xeon 2.5 Ghz, 4 gigs of ram, coolers, and some other miscellaneous crap... So far... still undercuts apple's near equivalent by 1000+ bucks. Im going thermoelectric water hybrid to cool system.. plans in development; going to implement custom temp controllers that monitor, compare, and takes action to preset and actual values... interesting part will be condensation control... first home computer encased within inert gas or vaccuum? Nitrogen? Got tons of cylinders at work. Let's do this shhhiiiiittttttttttteeeeeeeee

What model Xeons and ram did you get? I did not know Newegg sold FB-DIMMs with the super beefy heatsinks.
