How To Flash Ati Radeon Hd 4870 X2 For Mac Pro 4,1
I just got my ATI Radeon 4870 a few days ago for my Mac Pro '06. It works great. I am running 2 24' Dell monitors, one through DVI and one through a the minidisplay port with the mini to DVI converter I bought at Apple, and they run flawlessly. I run World of Warcraft at full setting without a hitch. 0) DISCLAIMER: don't do this. You will probably brick your video card and start your Mac Pro on fire. My information applies ONLY to a Mac Pro 4,1 running 10.8.0 with a stock GT120 in slot 1, and a Sapphire HD 6750 Vapor-X 1gb DDR5 card in slot 2. My Apple/ATI Radeon 5770 goes from my 2007 Mac Pro 1,1 to my recently acquired 2009 Mac Pro 4,1. My OEM Apple/NVIDIA GeForce 7300 GT comes out of storage and back into my Mac Pro 1,1, as it gets repurposed to a Backup Server and then, the OEM NVIDIA GeForce GT 120, from my ’09 Mac Pro 4,1, goes into storage. It’s an ATI Radeon HD 4870. Trying to do as much research as possible before contemplating the firmware upgrade. I use this computer quite a bit for work so don’t want to end up with a very large cheese grater that does nothing. As Peter Cohen reported earlier this week, Apple is offering up a ATI Radeon HD 4870 Graphics Upgrade Kit for Mac Pro (Early 2009 or Early 2008), and the company has now released information on.
Two days ago i was using my PC, then it suddenly shutted down. When i tried to restart it most of the time it won't showed me nothing on display, then, sometimes it worked well and showed me the normal pc boot with BIOS display etc etc, but after some time it rebooted itself. I opened the case the see what's was happening at PC's boot and one of the GPU's light was cheked, precisely that: 'D1601 - Red LED On, shows critical temperature fault'. The problem is that the -RED LED- light on at PC start, even after some hours of no pc-using. I thought there was some dust inside the GPU or maybe thermal paste completely dry, so i opened the GPU to clean it and to change thermal paste; doing so, i checked for some dust even on other computer's parts like PSU and CPU: they were clean! I tried to reboot the PC but the problem wasn't solved: in like 20 times i rebooted the PC only 2 worked well so i downloaded SpeedFan to watch my PC's temperatures and the only component listed 'hot' was the GPU at 60° (that's strange 'cause it's not a really hot temperature for the GPUs); so i manually increased GPU speed fan to lower temperature but after some minutes, PC always restart. I double checked everything, but now, after two days, PC won't boot: it start 'working' (fans and everything) but the LED D1601 on GPU always stay red and now sometimes even the LED D601 flashes!
