No, I'm not incorrect, because I didn't say that an unflashed 680 will show boot screens and kernel panics.
  • I said a GTX 680 will work, flashed or not, Apple drivers or web drivers, doesn't matter. This is true.
  • Then in a separate paragraph I provided step-by-step instructions to OP to capture his kernel panics, which will work for OP because he has a flashed card.
You merged two separate, correct points together into a third, incorrect point that I never made.
Lol not in a seperate paragraph, but in a completely new post, after the fact.. anyhows.

I didn't merge any points, I just quoted what you typed and commented on it. No biggie.

Anyways, it's all good. Thanks for the English lesson. Appreciated it.
 
Just an obvious observation, but if those blue lines are clearly visible on the screen and are not just a camera aberration, then I'd say your GPU is toast. Visual defects like that would likely be a sign of cooked VRAM and from my experience mean the end of the card's life.

Thanks, those lines come from the screen, not camera. I was thinking the same, probably GPU is almost dead

Thank you to everyone for your replies. In this link you can find the capture of my ketnel Panic.
Those blue vertical lines probably mean the card is almost dead as you said.

On the other hand, my GPU seems to be Nvidia Geforce 880 GT. I bought my Mac Pro 3.1 second hand around 3 years ago. I only opened it at the beginning to install additional RAM and extra hard disk (now I downgraded it to original condition, 2 GB RAM and one hard disk).

I tired to remove the hard disk and boot just fom DVD installation disk. Again after two minutes after selecting DVD as boot drive I got the kernel panic.

Is my GPU dead ? Need to get another one ?
[doublepost=1541329721][/doublepost]Sorry I mean "my GPU seems to be Nvidia Geforce 8800 GT"
 
ah, yes id gess it's toast

id recommend something like a used GTX 660 or gt 640 if you dont need boot display and check your display has the same cable as the gpu.
EVGA/MSI are good brands (well there who i have used :p)

on ebay the cards will be around £60 for gtx660 and less for a GT640 (buy a branded card there's a bunch of fake chines cards now)

those cards are just PC cards, iv been using PC cards since the GTX660 and then later moved to the GTX770 and now a RX 580 (you need to run osx10.12 to use an RX xxx card i think?) with no real problems for years, if anything iv been super happy to have stronger cards to use for work :D


if you need boot display look for a GT120 or try http://www.macvidcards.com/ but they will cost a tad more.
 
Hello everyone, thanks to this post I possibly debugged my startup issue. I was able to boot and flash my GTX680 but in a meantime while in and out with the card I probably remove one of the capacitor on the back. Does anyone know what capacitor shall I use? Voltage and capacity?
