5.1

Hello MacRumors, Ran into an issue yesterday after installing High Sierra onto my 5,1. I upgraded my 5,1 to HS as a part of my journey to Mojave, installation was fine and easy. My machine was previously running Sierra and Windows 10 on separate SSDs and I was able to switch back and forth...

Ihave a Mac Pro 5.1, 12-core 3.46 Westmere. I just bought 128gb of 1333 ddr3 ram for it, but it shows as being 800mhz only. I contacted the seller of the ram. Read what he said below. Is this correct and is there a way I can bring it up to 1333mhz? I took out half and it still says 800. I took...

Hello all, I apologize in advance if this has been asked in another thread but I can't find one that matches my setup. I have a 2009 MacPro 4,1 that has had the firmware flashed to become a 5,1 and allow the install of High Sierra. I was using it with the stock Nvidia GT 210 and then with a...

Do the RX Vega cards need to be flashed to work with the old Mac Pros? I've done a lot of research about Nvidia cards, but I don't really know how it works with the AMD cards. I've seen some stuff about editing kext files. If you do that does it work with the EFI, or would it need to be flashed...

Hi. First post so don't beat me up too much. My mid 2010 5.1, 4 core running 10.11 El Capitan has developed a constantly flashing power light. It won't boot. Fires up with fans & drives kicking in, but after a few seconds the power light flashes & that's your lot. I'm sure this has been...

Hey everyone, so I purchased a 2009 4,1 Mac Pro (Dual x5550) on Craigslist a couple weeks ago for $150. Honestly insane deal for how good of condition it's in. I painlessly flashed it to a 5,1, installed High Sierra, upgraded to 32gb of RAM, and installed a GTX 1070. I've had absolutely no...

Hello! I'm asking for a little help troubleshooting a Mac Pro build I am doing for a friend. He wanted something to help him with rendering 3d stuff his macbook was lagging with. I am not an expert but I have built many PC's and tinkered with upgrading many macs over the years. I personally...

Hello, My ATV4 is connected to my projector to the ceiling via HDMI. I then send the audio to an Airport Express across the room and my speakers are connected via Optical to the Airport Express. My current speakers are stereo and I want to buy a 5.1 Home Cinema but if the ATV can only send...

Hi I have a old Mac Pro 5.1 and I got a Gtx 980 (not flashed for mac). After I installed the webdriver for Mac OS 10.12.6 and Cuda and installed the gpu all my screens are black. I get no signal out of the gpu. I already tried to screen share with my MacBook to check if the driver jumps back...

Hi all, having some pretty big issues with my new 1080 8GB (purchased from Macvidcards). Have been getting no response from their support email which is a bummer so was hoping someone here might have a clue what could be going on. Im running a late 2010 5.1 Mac Pro with 64GB RAM, a 12 core CPU...

Good morning all, Like a few others here I didn't check the power requirements before buying the 1080Ti for my Mac Pro 5,1, and have been scrambling to find a solution for powering it which doesn't involve a secondary PSU or overtaxing the 2x6pins. I still have 1 PCIe slot available, and it...

Not trying to get too far ahead of myself here, but it does seem quite likely that I will get either the next Mac Pro or possibly an iMac Pro to replace my current mid 2010 Mac Pro. I really don't know much about GPUs, but I heard that NVIDIA now supports Macs and I wonder if it would be worth...
