Normally on when DIAG_LED button is pressed. To press the DIAG_LED button, use the nylon probe tool (Apple part number 922-5065). To read LEDs 1, 2, 7, 8, and 9, you must press the DIAG_LED button, which is adjacent to the LEDs. LEDs 3, 4, 5, and 6 are normally off and will automatically illuminate if an error occurs. The LEDs are located on the logic board between the two DIMM riser card connectors.

The Mac Pro (Early 2008) logic board includes a set of LEDs to help service providers troubleshoot the computer. The memory riser card diagnostic LEDs will also flash briefly when the computer is started up or shut down and when it goes in and out of sleep mode. Do not count this light as one of the diagnostic flashes. *Note: The status LED lights up when the power button is depressed at startup. Check memory installation instructions for proper installation order. Troubleshooting: Try reseating the memory DIMMs. An LED will light up on the memory riser card corresponding to the affected DIMM. An LED will light up on the memory riser card next to the affected DIMM or empty DIMM slot.ģ Flashes: A RAM bank failed extended memory testing. If the test detects a problem, the status LED located above the power button on the front of the computer will flash in the following ways*:ġ Flash: No RAM is installed or detected. Power-On Self Test: RAM and Processor VerificationĪ power-on self test in the computer’s ROM automatically runs whenever the computer is started up after being fully shut down (the test does not run if the computer is only restarted). Unplugged everything and restarted.still nothing.Īndrew Taylor, here are a couple things that may help to further trouble shoot:" Then ran OS X installer and installed Yosemite on the newly-formatted HD in the MP. I immediately got the "The disk you inserted is not readable." dialog on the MBP and used Disk Utility to format it. Today, I connected my MBP to one of the machines via Firewire and started the Pro in Target Disk Mode.

Is it because there's no drivers on the brand-new hard drive?įor what it's worth, I opened up the case and started each machine, and I see no LED indicator lights anywhere inside (I think there are supposed to be some, but I don't know where). I don't understand why I'm not getting any video (and no video is making it hard to troubleshoot anything else). But I get no video from either machine (I have two monitors plugged into each - one via HDMI and one via VGA). I bought a couple of new hard drives and a couple of new (MSI F5450 MDIGH) video cards, installed one of each into each of the two Xeon machines, and pressed the button.īoth machines turn on and the power lights are on steady. None of the machines had hard drives or video cards. The Xeon machines are the ones I'm trying to resurrect. Of the three I picked up, one turned out to be a dual-processor G5 machine, and the other two are dual-processor Xeon machines.

But it also requires a lot of tinkering, and I've never done it, so I can't tell you precisely what tinkering.I recently came across what seemed like a good deal on a handful of 2008-era Mac Pro desktop machines.

You could buy a PC power supply for $50-100, thread power cables from that through the back of your Mac, and still be under $800 even with the higher-end Vega 64s.

If you have free drive bays you can use the power from the drive bays to get some extra wattage. The Vega 64 is, but that's got even worse power consumption then the 56. None of these is anywhere near your budget. The really high-end AMDs, which are definitely supported, are even worse: The next one up (the 590, which has not been confirmed as working in Macs) is more like 300 watts:

The 8 GB 580 seems to be fine unless you're doing torture tests, at which point you max out at 234 watts in Boost Mode, so I'm pretty safe. To figure out the power draw on an actual card you should probably google the card name and "power draw." This is my card: If the card tries to draw too much power one of three things will happen:ġ) The card will not be able to function and it will crash, forcing you to restart the machine whenever you're about to get the performance you paid for.Ģ) the card will function fine, but it won't be able to go into TurboBoost mode (or whatever the equivelent is) and nothing crashes but your performance is limited.ģ) the motherboard will try to send more then 75 watts on one of those three circuits and something will burn out. 75 from the slot, and 75x2 from the two six-pin connectors on the motherboard. Your issue is going to be that the MacPro only really supports 225 watt video cards.
