Any news about some new NiBiTor version that recognize 32bit EFI? I have done cooler upgrade on stock Apple 8800GT (1st gen) and now I'd like to try some overclocking. Anoyone with success story?
I could use some help from the experts. I'm going to give you as much info as possible to help troubleshoot.
My Mac Pro was bought in Feb of 2007.
I bought the 8800GT card listed in the previous post, the eVGA model. It's the same part number as recommended.
I created a FAT32 partition in Vista and copied NVFLASH.EXE and the 8800GT32.ROM file from Altimeter to that drive.
I rebooted into the FreeDOS CD I created and choose the "DOS only" option, number 5.
I changed to the FAT32 partition and ran "NVFLASH --SAVE 8800orig.ROM.
I ran "NVFLASH -4 -5- -6 8800GT32.ROM". It said it completed successfully. I did a "NVFLASH --compare 8800GT32.ROM", and it said that they were the same.
I installed the 8800GT in my Mac Pro, making sure to attach the power supply from my old Radean x1900, which I removed from the system.
I started up the Mac Pro. I got the chime, and then the gray Apple screen, and then about 20 seconds later I get the transparent black "You Must Reboot Your Computer" screen (kernel panic?).
I reflashed back to the old ROM and was able to boot windows back up on my Vista machine. I retried the flash back to the Mac Pro rom and am still getting the panic.
Any ideas?
Thanks for the suggestions, guys! That's why I love these forums, everyone's so quick to help out, and they're usually right.
Waremaster has hit it on the head - I didn't install the Leopard graphics update. I'm a noob. Thanks so much for the suggestion, Waremaster, everything is working perfectly now.
hi. Pleas tell how u fix this problem: (I started up the Mac Pro. I got the chime, and then the gray Apple screen, and then about 20 seconds later I get the transparent black "You Must Reboot Your Computer" screen).
Had you read just ONE post further, you would have seen that he had fixed it.
I can't get enough power, so it won't work.What happens to the video card when you don't connect the extra power cable?
Thanks for the ROM!
Just flashed my EVGA 8800GT Superclocked and its working fine. I don't use bootcamp, so I can't report that side of things, but it's working fine in OSX 10.5.2.
This cable.What power cable do I need for the 6pin PCIE on the graphics card? Is the only option to get the ATI cable Ive seen someone on macrumors or is there a cheaper option?
Mini 6 to 6. The connector on the logic board is a little smaller. Good ole Apple.Thanks, is it a simple 6pin to 6pin or 6pin to 8pin?
Living in the UK makes that cable expensive for postage etc
How annoying, £18 for a cable for a card that cost me £55!
So instead of buying a cable I could just unplug the power from my DVDrw?
As it's not the exact same model, and from eBay, I'd err on the side of caution, and skip it. Even with the 7day return policy.http://cgi.ebay.com/EVGA-GeForce-88...14&_trkparms=72:1205|66:2|65:12|39:1|240:1318
It's N802, but it doesn't have -AR at the end, and it's also an OEM version.
thanks.

eBay just makes me nervous on certain things, and computer hardware is one of them.![]()
