Mac pro 2006 hd 2600 xt should work in bottom slot?

I was using a 3rd party hd 4870 in the bottom and was working fine. Now I was thinking of selling the machine but when I put the older hd 2600 in the slot there is nothing. All of the other slots work fine, I have yet to see if the 4870 will work if I put it back to test. The old one should work though? I did think though that the 4870 would register as x16 but always has shown x8 in the bottom. Would that indicate that there was a problem in the slot, that it was going out?

An excellent question ! Yes, the X2600 should work in slots 1 or 2, but I'm not sure about slot 3
see this entry at Everymac.com on PCI-E bus lanes
http://www.everymac.com/systems/apple/mac_pro/faq/mac-pro-pcie-architecture-lane -configurations.html
as far as I know, graphics cards go in slots 1 and 2, not so sure about 3 and 4. as you can see by the above entry, slot 1 has double width 16 lanes, slot 2 has 8 lanes, and 3 has 4 lanes. there may not necessarily be a problem in the slot, but that the 2600 XT likes to be in slot 1 or 2, and the 4870 could be a little less picky. The only way to tell if it is going out or not is to shut your Mac Pro down, take off the side panel, change graphics cards,including hooking up the power cable as needed, putting the side panel back, rebooting and checking under "About this Mac" then more info, then System report where it should show up as a PCI card in whichever slot you have installed it. Should you have hooked up the power cable and reinstalled the graphics card correctly in the correct slot and it doesn't show up in the system report at all, that could indicate a problem. just FYI, the 2600 XT isn't considered to be that great of a video card any more and may get clogged up with dust . You may be able to bake the video card to get a few more months' use out of it but this is a temporary fix only, and is not endorsed by anyone. if you could find an 8800GT mac version for a reasonable price, that might be a better solution

Mac Pro 2006, no display, TDM works. Video uploaded. Been to Apple.

Hi,
I have a Mac Pro 2006 and it's ben broken for a little while now. I tried all I could to fix it, reset everything, pressed all reset buttons on Logic Board, changed GPU. But the problem remains. When I start it the mac chimes, as usual and starts up in Target Disk Mode if I hold T (as it's obviously supposed to). The video shows you what happens when I start it up in regards to diagnostic LEDs.
http://youtu.be/jCMPG7Be9WE
Back in the Autumn I took it to an Apple Store. They said it needs a new Logic Board. I don't believe they are correct. If it starts in TDM and starts in alternative boot mode (holding alt key) but does not display anything surely it is a different issue and I shouldn't have to pay for a new LB, which they quoted me £300 ($500US) for?
Can anyone offer any suggestions?
Thank you.

My MacPro 3.1 (QuadCore 2.8 GHZ, 8 GB RAM, ATI X2600, Mac OS X 10.6.1) has the same Problems for some days.
At first I thought it didn't boot up at all, just after several trials....
Then the screen kept blank for several days....
Today I realized that it was booting and kept running until sleeptime.
Via remotelogin I can see a smaller desktop, Aperture tells (my iPhone has new Photos and Aperture is my default for iPhone synching) me the GPU is not supported and SystemProfiler reports that the GPU is not recognized.
I don't know what's happening, I had some graphical faults in the past week (the space for the fast-user-switching-name was blank for a few days and so on, reboots helped)...
Then the disks (booting Leopard from a 2x500GB RAID-0) were just recognized after every 4th to 5th reboot...
Seems to be really a GPU Problem, will try to swap the ATI X 2600 from one slot to another within the next days...

Mac pro 2006 won't recognize ram

Hey Everyone.....I'm not a giant techie, but now my way around a computer more than most I guess...here's my question...
I have a Mac Pro 2006 running 2ghz dual core xeon processors and with 2gbs Ram (2GB x 4).....I just finally upgraded my ram and purchased 8gb's (4GB x 2)!
I installed the new ram in Riser A in slots 1 & 2, and moved the old ram all to Riser B in slots 1-4 but I think I screwed something up. I booted up my machine and it recognizes the 8gb modules (whew!) but doesn't recognize the old 2gb's. I don't know what configuration I should use.
Should I have Riser A full with slots 1-4 occupied by my new 8gb's and a pair of the 512's, putting 9gb's on Riser A?? Then I would put the second 512's on Riser B?? 9 on Riser A and 1 on B??
8GB Ram is making such a great performance upgrade, but 10GB's of Ram would be pretty sweet too!! :)
Thanks for any and all help.

Assuming that the new RAM is for Mac Pro and "look the same"
Sometimes two brands or different sets from the same make don't get along.
Where you installed is fine.
I didn't understand what it was, and what it is now.
You have:
4 x 512MB for 2GB
4 x 2GB
2 x 4GB
Ideal would be
Riser A: 2 x 4GB
Riser B: 2 x 2GB
See if that works first.
Run Apple Hardware Test
The math and figures you posted don't add up for me.

How can I connect older Mac Pro (2006) to my network wirelessly?

I just got a new (2012) MacPro that I can connect wirelessly to my network. I'm moving the old Mac Pro (2006) running OS 10.7.5 that had been connect via ethernet cable to the other end of the house. What do I need to get to connect it wirelessly?
Thanks,
Carmen

Carmen,
Since the Wireless card was optional back then, you may not have gotten it in your original config?
You can verify if the hardware is installed several places, as Bob mentioned, do you have the option to enable wireless under your System Prefs \ Network (I would imagine not, since your asking). However, while very unlikely, it may be installed but your not able to see/select it for some reason?
So, just to make sure, you can also verify via looking under "System Information" (you'll want some info from there anyway).
"Apple Menu : About This Mac : More Info : System Report : Network : (look for Wi-Fi etc.)" if it exist you'll see the card and info about it.
If you don't have the option nor see a card was installed you can go about this a few ways.
1. The absolute easiest route (to NOT have to deal with 3rd party drivers or possible 3rd party issues when you upgrade your OS etc) is check out places like Macsales and see if they have any of the original Air Port extreme cards available and install yourself. - http://eshop.macsales.com/item/Apple/BCM94322MC/
2. You could talk with Macsales and ask which external USB wireless card works best with your rig (least fussy) and go that route. While several brands work just fine, you just never know when something changes in an update and then your faced with the old pointing fingers thing. Rare, but still....
Also, while your in the System Information area you'll want to note your model, if it's 2006, I think that's Mac Pro 1,1 ?
Hope that helps.

After update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.

hello,
after update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.
the used ports appear to be "killed"; the unused USB ports seem to work, but the Mac works in slow-motion.
The only "solution" is to restart my Mac.
- SMC-reset, PRAM-reset or repairing user rights had no positive effect; what is the solution - a bug-fix-update???

I have a mac mini (A1283) with OS 10.7.4. Upon upgrading to 10.7.5 it did not start up again. Instead, the light was on and the hard drive did not start up. The light on the connected USB mouse was not lit.
My solution:
Cold start with Command-v pressed.
This should start Verbose mode (see http://support.apple.com/kb/HT1492 ).
What happened on my mac mini was that the grey startup screen with the Apple logo appeared for a long while before the login screen came.
Maybe Cmd-v set open firmware params and fixed some corruption.
Anyway: my mac mini works again.

MAC Pro 2006 PSU test

I'm hoping sombody can help... My MAC Pro 2006 model just died... completly dead I believe it to be teh PSU but need to test if with a multi meter.
Does anybody know which pinouts need to be jumpered first from teh J1, J2, J3 and J4 plugs?
As all wires are black and no info on the web I'm at a loss without just buying new bliend.
Thanks in advance

They work off a fixed price list, not time&materials. So call or visit them and ask.
Have a defibrillator nearby.

You can write to Apple with the serial number and they can tell you exactly when your MacPro (as opposed to Mac Book Pro) was manufactured.
And in the Apple menu > about this Mac > more info > there should be sufficient detail to narrow it down.

Mac pro 2006 won't boot after lion install

hi,
under 10.6.8 everything worked fine. All adapters and peripherals were functional.
After a normal looking lion install my mac pro 2006 will not make it past the boot screen (Grey Apple logo with spinning wheel). After a while the spinning wheel stopped spinning but I hear disk I/O continue for some time. A verbose boot lists the usual output. The last line visible has a mention of macos_swapon or something like that. I do note the first couple of lines specify a 64 bit kernel is booting. I was under the impression that this machine cannot run the 64 bit kernel from snow leopard discussions.
The video card is an upgraded one (i.e. not the stock card that came with the machine). However as I said before it was working fine under snow leopard.
Any ideas?

I have the same problem. I did a clean install of Lion and created a temp account. I was able to use Lion for a bit, then I used the Migration Assistant to bring my regular accounts back in from an external drive. When that completed I logged off of the temp account and into my main account (without restarting). Still no problems, Lion was working fine. I shut the Macbook down for the night. Now that I'm powering it on the next morning, I only get the Apple logo and spinning wheel.
I tried a PRAM zap, but it didn't help.

Mac pro 2006 dont boot but fan's running like ****.

guys, my mac pro 2006 starts with the fan loud , seems running at total velocity. The video card doesn't show nothing. The usbs dont work. when i extract the video card , the problem is the same. I take the memory too, and the hd . The problem keeps going on.
The fan start's from zero to a million rpms.
The check leds on the motherboard are ok, no one of them are lighting. If i take every part of the machine and i put them outside, the same thing happen.
can you helpme?

Make sure your Ram is paired correctly when you install it --
And the long boot time is due to the previous reply. If you don't set a 'boot drive' the mac pro will look everywhere before selecting the OSX installation.
I've got the dual 300GB Velociprators in raid 0 with 80GB Intel ssd boot drive in my mac pro (same as yours). You can also boost your clock speed by a software trick .. I can get mine over 2.9 MHz before errors start popping up in console.
(problem is it screws up video playback and time)

Mac Pro 2006 won't display anything

Hi
My mac pro won't display anything. I've had a look at this http://support.apple.com/kb/HT1573 and one of the first things I did was reset the PRAM & NVRAM. The 10.6.8 install is fully updated. The startup chime plays and fans run normally.
I have:
re-sat the RAM,
cleaned the RAM
cleaned the inside
removed all the HDDs except the main one
and even used another Raedon 4850 in place of mine.
It starts up in Target-Disk mode fine, I am using it with my iMac now but it is not the same (iMac is only dual core andhas half the RAM) I've tried several screens; DVI, VGA and HDMI all without luck. It's obviouslt out of warranty and I don't want to take it to a Apple store anyway as I ocassionally build & repair computers myself so am fine with trying anything out.
Thanks in advance,
Eric.
Things I could do/ haven't done:
Remove/ replace the Logic Board battery?
test the power I/O?
start in Safe Mode?

Whoa there, sparky !!!
Is there something you aren't mentioning?
Since there has never been a Mac Pro 4850 and you have mentioned this number twice I would like to ask...what aren't you telling us?
Did this computer work fine until one day it quit? Or did you buy/inherit/find it broken or in an unknown state?
Any GPU used in a Mac Pro needs to have EFI on it to do this basic debugging stuff. While PC WIndows BIOS cards can be used if the system is A-OK and gets to desktop, it is basically impossible to use them on a system with issues.
So, if the 4870 has a DVI and a MDP port it is real Apple one and SHOULD work.
If that card died and you have tried replacing it with a WIndows/PC 4850, then you have broken the scientific rule about only changing one thing.
Ideally you would have another Mac Pro to test your GPU in and another KNOWN GOOD GPU to test in your Mac Pro. The EFI thing greatly complicates things, unfortunately. Even a "Mac Pro" video card won't necessarily work if it is for "the other" series of Mac Pro. Ther have been in effect, 2 different Mac Pros as far as video cards go. EFI32 and EFI64. ATI/AMD cards have been largely unaffected by this but Nvidia cards MUST be for right series.

Lion install bricked my Mac Pro (2006 model)!

Hello,
I apologize for the inflamatory title but I figured the problem I have is real and Apple engineers are more likely to notice the issue with this title. My apologies if you already noticed my other post.
My Mac Pro 2006 (first Intel model - dual Xeon 2.66GHZ 8GB) was running fine under 10.6.7 and 10.6.8.
On the first reboot after the Lion install starts I get the boot screen with the Apple logo and the spinning wheel. After a while the spinning stops. The screen stays this way. Disk IO continues for a little longer but then stops (mostly). I can ping the machine (DHCP server providing a fixed IP address for the Mac PROs MAC Address) so I know it is somewhat functional. On another Mac the Lion install went fine. On that Mac the first thing that happens after the spinning wheel stops is the screen goes into GUI mode. So I surmise my problem has something to do with graphics.
When I power cycle and boot with verbose mode I notices a few items of interest:
1) 64 bit kernel (I thought Apple only supports a 32 bit kernel on this vintage of machine)
2) A couple of unrecognized device line items. (I took out a Sonnet expansion Firewire/USB PCIe card and one of the messages went away on a subsequent try.)
3) The last message I see says something about macosx_swapon (or something close to that). After that no more screen messages even though disk IO continues.
I rebooted the machine with an external firewire drive running Snow Leopard. Everything worked fine. I went into system profiler and retrieved the info on the video card.
NVidia GeForce 8800 GT
Vendor: 0xde
Device ID: 0x0600
Revision ID: 0x00a2
Rom Revision: 3233
While the Lion specs do not call out specific supported video cards/chipsets, they do mention this card is supported for openCL under Lion so it sounds like the card is supported.
What I request is a patched Lion installer kit. I can run this from said external drive after copying the patched installer from my functional Mac. I'd also strongly suggest the installer thoroughly interrogate the hardware to determine if there are any incompatibilities before the installer triggers the reboot.
Is there a way I can determine more diagnostic information to subsequently post in this discussion? Maybe there is a command I can issue in single user mode?
Thanks in advance!

Seems I'm not the only one having this issue. I installed a GeForce 8800GT in my 2006 MacPro 1,1 (2 x 2.00Ghz Xeon Dual Core) that I got off eBay recently and I've also had the same issues (freezes on Apple screen, spinning logo). I actually installed Lion before I put the card in (old card GeForce 7300GT, came with the system) and it worked OK. But when I put in the card, the problems started.
But I did get an eBay message from the seller who sold me the card, and it turns out at this stage that the Lion drivers have a problem for some reason for 8800GT.
Here's the info from the system profiler if this helps:
NVIDIA GeForce 8800 GT
Vendor:          NVIDIA (0x10de)
Device ID:          0x0611
Revision ID:          0x00a2
ROM Revision:          3233
Seems to be a widespread issue at the moment....

Can I use a Asus Nvidia gt640 with a mac pro 2006?

Just got my first intel mac! Not the newest thing but it will do. I just have a quick question, can I use the Nvidia gt640 2gb with a Mac pro 2006 with no flashing of the system or the card. Thank's. -Edward

First, you need to look at what OS version you have. Mnay people (myself included) running some of the newer OS version are using Nvidia cards not released for the Mac. OS X Mavericks for example will support these cards, but you lose some functionaility (boot screen, etc.) Once the machine is up and running they work fine.
With a 2006 model you are before the 3.1 machines and therefore limited in the OSX version you can run. I think you need at least 10.7 Lion.
So if you can run 10.7 the answer is probably, but then you will lose some basic functionality. For many this is not important.

How I connect a 27 " Mini DisplayPort Display to a Mac Pro 2006?

Dear All,
I need to know if I can connect a 27" Mini DisplayPort Display to Mac Pro 2006
Thanks a lot in advance
Subalv

You can certainly do that, the Apple Online store sells it for US$150.
http://store.apple.com/us/product/H3938LL/A?fnode=MTY1NDA5OQ&s=topSellers
I have not tested it. It is certainly good to know it exists. I hate paying the premium for "leading edge" equipment, so I am writing from my 2009 Mac Pro with used Apple 30 inch Cimena display.
If I were to pay what that new display costs, I would buy a new display card to drive it directly. My recommendation is to upgrade your diplay card for US$100 more (than the cost of the adapter) and get a card capable of Dual-Link DVI AND two Mini Displayports.

Mac Pro 2006 Kernel Panic

My stock Mac Pro 2006 just started showing the Kernel Panic screen at start-up. First saw the Kernel Panic this afternoon after leaving the system for less than an hour with a game running (EV Nova in a Pause screen). A reboot brought the system back up for a while, I was running Safari for maybe 10-15 minutes when the Kernel Panic screen showed up again.
Tried the three stock Apple-recommended reboot options, reboot with X key down, reboot with Opt key down and PRAM reset and reboot. No luck; the Panic Kernel screen came on after each one. Also tried the original OS X 10.4 install disk during and Opt key reboot; same Kernel Panic.
And 10.5 and 10.6 universal upgrade disks; the 10.6 disk got to the grey screen with the Apple logo and the spinning activity symbol which stopped after a while, the Apple logo went away and no further screen activity; the 10.5 disk actually got to a light blue screen with a cursor, but no other icons, the cursor did change to a text I-bar at certain areas in the center of the screen and the disk drive would spin up after some mouse or keyboard activity, no screen activity and no further progress.
The boot drive appears to be accessible as the OS on it shows up during the Opt key start-up. I also reset the PRAM several times, so do not think that is the problem. Could the battery need replacing or possibly I have a RAM module just go bad on me?
Suggestions? Thanks in advance.
Dave

Update: I have switched out every RAM module (4 X 512 MB) in turn and switched the two riser cards in every combination of one pair of RAM in the top riser card. After each reboot, the kernel panic screen comes back. Could one bad riser card, even if unpopulated and on the bottom cause the kernel panic? Any way to test my system more without swapping parts other than the RAM in and out?

I have an older Mac Pro (2006). I want to install Boot Camp and Windows. I have installed a boxed Snow Leapord on the machine. And it says the download of the Boot camp drivers cannot continue because they are not available. But at that point I have not inserted a windows disk, so how does it know i have XP?
So it appears I am limited to Windows 7? And where are the Windows 7/Boot Camp Drivers? On the OS disk?
Finally, since I have necer considered Windows 7 before, I assume there are no compatability issues with mainstream applications that were running in XP?
Thank you.

You're welcome
Just remember to reformat the partition (bootcamp partition) to NTFS with the windows installer, ensure to pick the correct partition.
