After a few problems updating my card I got everything working in OSX. I updated my OS first before flashing the ROM and after flashing I had severe tearing. So I did some reading and found a post that recommended using the actual downloadable combo 10.6.2 file for the update followed by installing the QE_CI_Exotic patch 10.6.2.pkg. I must note that I did follow the ATI flashing tool instructions the first time and did install the 10.6.2 from the tool itself before rebooting but that did fix the tearing problem. It was only after downloading the combo file, installing that, then installing the QE_CI_exotic file before rebooting that worked.
After doing this the screen tearing went away and everything seems to be fine in OSX...Bootcamp however is another story.
When I try to boot into bootcamp (I have bootcamp 3.0.1) I have severe artifacts when booting to windows to the point I can barely make out what is behind the artifacts.
If anyone has any suggestings to get this card working in Bootcamp let me know.
FYI the card I have is the Sapphire 4890 new edition with Hynix memory. I have tried flashing with both the E115QA1G ROM posted here as well as a newly released file provided in the ATI Flashing Tool forum. These may be the same file though as they both work in OSX and fail in bootcamp.
Hi Altimeter88,
If this could help you (mainly points 3 and 4):
In order to test Sapphire 4890 New Edition (NE) outputs, i wanted to be sure that they were running on XP, instead to remove again the GPU from MP, installed it on PC and reverse, i've installed Bootcamp (3) and XP.
XP alone can't be installed with Bootcamp (minimum required is XP SP2).
1 - Fortunately i found a tutorial (in french) "how to integrate SP3 within XP and make a bootable cd"
http://www.tutoriaux-excalibur.com/integrer-sp3-xp.htm, this tutorial is using nLite (
http://www.nliteos.com/index.html).
2 - After XP installation and reboot, BootCamp XP was not using NE, 30" ACD connected to NE DVI was black, only NVidia 7300 GT was working on 20" ACD.
3 - With 20" ACD connected to NVidia, i did install Catalyst 9.10

and open Catalyst Center,
4 - With the help of Catalyst Center, XP was running 4890 NE with a 30" ACD attached to DVI and 20" ACD to HDMI / DVI adaptor.
5 - DP to be tested may be tomorrow on OS X and XP (DP / DVI adaptor not yet received).
6 - Keyboard is apple alu wired cable and mouse is bluetooth Mighty Mouse 4 buttons.
7 - Mighty Mouse was not working, i've been obliged to connect an USB one.
8 - The problem for the mouse IMHO is that XP didn't scan for bluetooth equipment, i've opened Config Panel, Bluetooth, asked XP to be detectable, Mighty Mouse was detected, paired and is working very well.
9 - I'll try again with Magic Mouse if she likes to visit my house a day, shipped on 28th Oct, not yet arrived, she has, may be, crossed Oil Can Harry's path
