I did not know that this was possible with such old hardware or DVI in general. #2008 mac pro 3.1 specs install#One last observation for the night: spun up a clean install of High Sierra and the 8800GT can push a 4K monitor at 30hz. #2008 mac pro 3.1 specs pro#Overall pretty slow pace here, mainly due to shipping speeds to HI though I’ve also just been too busy to give the antique Mac Pro more proper maintenance. All told I’m about $300 in parts into the restore and probably a bit over 8hrs now. Later next week the second CPU ($12) and another set of new RAM will be here along with a spare PSU for bench testing and possible swap out. I ordered a replacement EVGA 4GB card to reduce that variable. #2008 mac pro 3.1 specs Pc#It does boot out through DVI-1 only in a spare PC though shows in all three latest MacOS builds as an unnamed Nvidia 6Mb card. The GTX 680 that I received today had been improperly flashed and the seller killed the card. I’ve stripped the machine down to the logic board, well almost, as I wait for the second CPU and some deep reach Allen keys to arrive, then I’ll reseat the CPU and go from there hoping that the PSU and logic board aren’t shot. Most importantly is that I can’t get the machine to boot. I had a few hours to tinker this morning before the day got hectic and made some findings. I wish you the best and would recommend you do take your Mac Pro apart annually to remove the dust it excels at accumulating. I do not remember how much RAM I have at my disposal currently as I haven't committed those upgrades to memory. I used to boot from my RAID 5, but that became a headache for reasons I don't now remember. I boot my Mac volume from here and utilize the RAID above as a form of "internal / external" storage. I have a Sapphire HD 7950 Mac Edition installed along with another SSD connected to the last remaining PCIe. I do know that I replaced the secondary Super Drive with an SSD installed using a special mount and connected that SSD to some unconventional part of the logic board this SSD houses my Windows volume and is accessed by bypassing Apple's RAID Card which would otherwise prevent windows from booting. I'm away from my Mac Pro at the moment, so I'm straining my memory to recall how exactly I "modified" it. I can't offer any substantive advice with respects to your 3,1, but perhaps the PSU might warrant some attention, if not now in the future. From what I read at the time I was trying to have it addressed (and when the issue was plaguing me the most), I had come to understand this issue to be endemic with other Mac Pros. My early 2019 Nehalem 4,1 Mac Pro has some issues with its PSU. OK, more soon, this will be checking off a bucket list item for me and hope that you’ll enjoy my enthusiasm as the build unfolds. #2008 mac pro 3.1 specs upgrade#It looks quite easy to upgrade the wireless chip though that’s expensive for what you get in return and I’ve got LAN nearby. It’ll be my new shop toy and will mostly serve as a terminal to login to the home NVR, view files, regular work communications, and of course to pump out optically perfect Toslink to the shop AV. What will the computer need to do? Not much, it’s a piece of jewelry. ![]() #2008 mac pro 3.1 specs drivers#That’s mostly SSD theft, though I might try out the GTX 1060 from it and say an install of a High Sierra to leverage that GPU (still no sign of drivers from NVidia for Mojave and 10xx cards). Other plans: merge my shop computer’s guts with this. So dual boot in the end, and the early OS will require that I track down a working older GPU as the 680 requires 10.8 or later. To that end I’ve got a GTX680 on the way so that I’ll be able to run Mojave on it, though my stronger interest is in restoring a fully classic install of 10.6.8SL as that was my favorite Mac OS. Even the mainboard’s battery still has over 3V. Specs as I can tell are a single 2.8Ghz QC Xeon, aforementioned dead GPU and good RAM, the mainboard appears to be working perfectly, and we’ll see about the optical drives as I get it to boot. ![]() Power Supply checks out, fans all spin up, RAM riser LEDs all go blinkers blink at power on. The verdict is that the OEM 8800GT graphics card is shot, and that there are four good chunks of 1TB spinning rust in the sleds, and 4GB of DDR 667 EC-RAM. ![]() Tonight I had the energy to take apart the machine for testing. With it I obtained the original box and keyboard/mouse combo. It lived in a climate controlled environment since being deployed in ‘08 though the business was shuttered for three years. The MP that I’m working on is a pull from a small audio production business. Gonna just drop this topic here for now while I’m waiting on parts to roll in as I’ve always wanted one of these machines but could never justify the expense.
