gpu failure

I know this is probably the faulty GPU, but just wanting some answers behind it or if it is the faulty GPU. So I have this 2011 15 inch MacBook Pro with a defective AMD GPU. I have disabled it using the PowerPrefs command in Single User Mode and the Terrascale 2 Accel is off for OCLP so it does...

I have a 2015 15 inch MacBook Pro, the Radeon M9 370x model. If anyone has any expertise with the below I’d be very grateful for help! Please see all facts and testing so far: It started turning off to a black screen with the fans high. When it rebooted it would give an error log, panic(cpu 6...

I posted before that I had managed to bring a late-2009 iMac back to life after a thorough dust clean-out and system update, in the thread 'Brought a 2009 iMac back to life - now what?' https://forums.macrumors.com/threads/brought-a-2009-imac-back-to-life-now-what.2296404/ Sadly, that didn’t...

(This was supposed to be a thread for sharing some good news. That good news will probably have to wait a while longer.) Anyhow, if you’ve read this far, I’m thinking this board will have to come right back out and be returned to the seller. I hope I can share much better news sooner than...

I bought a Mac Pro with 16 core about 2 months ago, it came with a Radeon Pro W5700X. I upgraded to a Vega II card so I coud have rendering of video done faster using the GPU of the card. At first it worked fine and Final Cut pro was using about 80% of the GPU when rendering and exporting file...

Hey all, I have an old Macbook Pro Late 2008 (5,1) with dual GPU. One of these GPUs is broken. Nvidia 9400M is default graphic card, so my mac keeps rebooting and I can boot it only in Safe mode. Is there any way to set 9600M gpu as default? By terminal or something? I've been trying with gfx...

Hey all! My mac has been a rockstar since I’ve owned it! A couple days ago it was working fine, I left to go make dinner, came back and it was in a reboot loop. It would display the apple logo, start the progress bar, load 1/2-3/4 of the way, flash to a grey screen, and reboot. Once I saw it...

Hello everyone, hate to be a bother, but my first post is one asking for help troubleshooting a peculiar issue I am currently having with a 2010 Mac Pro I picked up. Other than missing ram (which I have replaced with a random stick I had laying around, and some dust, it seems to be in complete...

Hello all, Shot in the dark here but, I use a Mac Pro 3,1 (2008) with FCP 7 and have been experiencing some upsetting issues with the entire system and machine freezing and becoming unresponsive. The issue has only been taking place while I am editing or playing back HD clips or video. After...

Recently tried to install a GTX 980Ti in my 5,1 MP, but not getting any signal. I ordered a GT120 off eBay so I could install the needed drivers for the 980. Is there anything I can do in the meantime? Is there a chance it is not a drivers issue? Thanks in advance!

So I got my hands on a 5,1 Mac Pro with dual x5680, and I put in a 980Ti, but I don't seem to be getting a signal on my monitor. From what I understood, the new gpu isn't initialized because of missing drivers, so I went ahead and purchased a GT120 off eBay so I will be able to install the right...

When I purchased my new Sapphire 11265-05-20G Radeon Pulse RX 580 8GB GDDR5 Dual HDMI/ DVI-D/ Dual DP OC W/BP (UEFI) LITE (from Newegg) I only made a cursory investigation into the necessary Dual Mini 6 Pin to 8 Pin PCI-E Power Adapter required to power the GPU. Now that the card is kaput after...

Back in June 2012 when I gazed upon the newly released MacBook Pro with Retina display, I know that it was the machine I wanted to purchase. It ticked all the boxes; had good battery life, great screen, CPU, GPU and all I wanted back then. Sadly the demand was rather strong and I waited for 2...
