Radeon 4850 issues after EFI Firmware 1.4?

[Hindesite]

I got my wife the new iMac with a Radeon 4850 to replace her ancient PC (and I meant ANCIENT) and she had massive issues with lockups due to overheating, especially when playing fullscreen 3D games like World of Warcraft in Mac OSX or any of her Windows XP games in bootcamp.

After the EFI Firmware Update 1.4 she's had far less issues, but she's still had 1 lockup (playing Diablo 2 stangly enough, a very old low detail game) and graphical glitches in WoW which caused her to stop playing out of fear of a lockup before it could happen.

Her computer temps are still extremely high but our house temp is only 72degrees. What gives? Anyone else having this issues still? Anyone else have a solution??


Thanks ahead of time.

The new EFI fixed these problems for most users, but it is possible that the GPU in her Mac is faulty, or that there is some other hardware component problem.

I've run my 4850 equipped iMac for literally hours on Crysis (under Win7 Boot Camp) which is one of the most demanding games you can run. The top of the Mac gets hot enough that you could probably cook a traditional American Breakfast on top of it, but I have not had one single lockup in hours of play. In fact I'd say that overall the iMac has provided me with a more hassle free gaming experience than the PCs I've owned.

I would recommend you contact Apple and explain the problems you're having, they might need to run diagnostic tests on the machine and see if something is wrong.

Alright, I'll have her contact Apple then. She got the extended warrenty so we should be good to go.

Thanks.

when i bought my imac, the efi update was on it already. i had pc version of diablo2, so i had to register an account on battle.net site, and downloaded the mac version from there. i've ran it for about half hour without problems, though i don't really play the game anymore. as for wow - never tried it, and not planning on it. i'm on 10.5.7 (combo updater)
