Hello, i would greatly appreciate it if anyone can help me with this problem(s) that iam facing with a mac pro 1,1 (upgraded to 2,1). ** Sorry for the long post, but i would greatlt appreciate any feedback. THANKYOU*
I received a mac pro 1,1 from a friend a mine with 10.7, nvidia 7300 gt and around 5 gb of ram. i decided to mac this a project system and make it run a much newer operating system. I would have to admit iam still new in the world of macs, but iam been trying to learn along the way. I upgraded the unit with 2 xeon x5365 and i also upgraded to 32 gb of ram. I then decided to upgraded the gpu to a xfx 5770 HD-577A-ZNFC pc card. I knew that some cards theres no boot screen, i so waited for a long time and no screen showed up. i connected it with dvi- hdmi connection and hdmi and no signal. Tv does pick up the ports being used but no signal. I then decided to flash the card to have mac bios, i installed it back and i get a boot screen and it loaded to 10.7. however i would get a flickering screen/black bars for a few seconds before login screen and after login screen. I had previously tested the card on my old pc and it worked, so i dont think its the card i hope. after researching, i decided to upgraded to EL capitan. After installing el capitan and changing the boot.efi, i see the loading apple loading screen, but the bar stops half way and stays like that. i tried reinstalling el capitan several times and same issue. I got tired, and decided to connect the 7300 back to see if something happens, well it loaded the whole bar. however, its doing the same flickering/black bars for a second before and after login screen. I also notice that the launch pad lags alot and when i put a video in full screen. i suppose that anything in fullscreen lags, because it looks fine in the desktop. I tried using a power color hd 7750 with the 7300 and i see the boot screen from the 7300, but the bars also stays stuck in the middle with the 7750. Sorry, i made this post in a hurry but i can answer any questions. i will upload some diagnostic files i found.
