IMac :: Won't Work With Radeon 4850 After EFI Firmware 1.4
May 30, 2009I 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.
IMac :: It's The Radeon HD 4850 Better Than The HD 5670
Jul 27, 2010Who are well aware of the difference but video cards is something that i am not familiar with. I'm deciding between i5 refurb or the new i3 i am more interested in graphics power than cpu btw

Mar 3, 2009I'm going to be ordering my new iMac within the next couple days but need a little advice first.
Obviously, the 4850 is more powerful, but if these two cards had the exact same specs, would ATI or nVidia be the better choice?
Which company is Apple leaning towards, which company produces better Mac drivers, how will OpenCL play into this, etc.
IMac :: ATI Radeon Hard Drive 4850 GPU?
Oct 25, 2009Loving the new iMac revisions and have placed my order for the Core i7 configuration with 8 Gigs of RAM, the only thing that slightly concerns me is Apple putting the ATI 4850 GPU in this machine as this card has been around for well over a year. Having a young family my iMac really has to last me (current Mac is my old but faithful 800Mhz G4 Angle Poise 17" screen iMac) so don't want to get caught out with an "old" GPU that within a 2-3 years won't be able to cope with current day demands placed on it. My usage is photo manipulation, a bit of FCP and I want to be able to play some 3D games etc. but I'm by no means some games enthusiast who requires the highest frame rate, highest settings. Figure I have two option:
A. Bite the bullet now - this iMac has almost everything I want - been waiting for Quad Core desktop chip and LED screen but icing on the cake would have been better GPU and Blu-ray option.
B. Wait yet another update (figure March / April 2010) in the hope that Apple put in a more current GPU and possibly Blu-ray option. HOWEVER I figure that this is probably a fools game as who knows regarding Blu-ray and obviously a more current GPU will be fitted but probably won't be the most extreme one as Apple tend not to figure that this is a priority on the iMac.
My inclination is that this update will probably be absolutely fantastic and my GPU worries are probably unfounded as I'll never want to push it to gaming extremes but interested what others may think.
IMac :: 4850 EFI Firmware Update To Fix Freeze Ups
May 2, 2009It's avihappy again and I have another survey for you all. As you can see, there is now an iMac 4850 EFI firmware update available via software update. So can you: Find a test that will cause the iMac to freeze up. Do the update. (make sure you actually run the firmware updater tool, it may not run automatically when you install the update from Software Update.) Switch to WiFi. Do the test again. See if the iMac freezes!

View 8 Replies View RelatedMac Pro :: Radeon 4850 Power Connectors?
Aug 10, 2008I have bought a Radeon 4850 graphics card to play some games in Windows under boot camp. The card comes with a mini 6 pin power connector that connects to the graphics card and supplied lead has at the other end a 4 pin power connector to go into the computer's power supply by the looks of the diagram in the box. My question is do I need to connect this to the Mac Pro power supply? The ATI 2600 card in the machine doesn't look like it connects to another power supply.
If I do need to use this then I can only see two small power connectors on the motherboard near the fan, does anyone know anywhere in the UK that would sell a compatible power lead?

IMac :: ATI 4850 - Desktop Or Laptop?
Mar 17, 2009I wrote it in another thread, but maybe I went OT, so...Does anyone know for sure if the ATI 4850 is the desktop version or the laptop version? I'm going to order the iMac24 but I want to be sure that the ATI card worth the money.
View 24 Replies View RelatedIMac :: ATI 4850 - Old Leopard Installation
Apr 15, 2009this is my first posting but I am desperate and need some help Apple could not provide. Here is my situation:
- new iMac 9,1 2,93 GHz, 4 GByte, ATI Radeon 4850
- pre-installed OS: Leopard 10.5.6
I have access to a MBP and an older iMac. The MBP had a defective logic board some months ago so I decided to copy its content (after repair) to an external hard drive. I used this hard drive as my primary OS and used it with the MBP or iMac and did have the same data all the time - excellent time-saver for me. Now the new iMac was shipped yesterday. I tried to boot it from the very same external hard drive as well. It worked but there are some annoying facts I need some help to deal with: I cannot activate sleep mode with the new iMac. The graphics card seems not to work well: stuttering screen saver, slow high definition video playback, slow spaces etc. I cannot dim the monitor's backlight with F1/F2 keys nor the monitor setup. All these problems disappear when I boot from the internal HDD but that is not an option for me. It looks like the "old" Leopard installations lacks of some drivers. Is there a way to add them, is there another solution or will an update of Leopard 10.5.7 - at least most likely - solve the problem? Apple support did not feel the need to help for "exotic configurations". I was told a fresh installation of a retail Leopard copy on an external hard drive COULD work (no guarantee) but it would take me too much time to re-configure and I don't feel the desire to set up my system fresh and new like in old Windows days.
IMac :: How Hot Do The 4850 Machines Run Compared To The 130 Or 120?
Apr 27, 2009Has anyone done some sort of a comparison?
View 11 Replies View RelatedIMac :: Nvidia 130 Versus ATI 4850
Jul 13, 2009Is there much difference from a stock iMac with Nvidia GT 130 vs ATI HD 4850 for gaming? It would be nice to be able just to buy a stock machines rather than a custom with the ATI for $50.
My real concern is overall gaming proformance and heat produced by the two cards. Current iMac has the ATI 2600 HD Pro, which I think is pretty slow compared.
IMac :: 5750 Slower Than 4850?

IMac :: Finding A Quad Core Or The 4850?
Nov 17, 2009I know 300 dollars for a bump from C2D/4670 to a i5/4850 is easily one of the best upgrades Apple has offered in a long, long time.... but would I really need it?
I was primarily going to be using the iMac for everyday stuff (word/browsing/etc) and for games occasionally by others. I don't need everything running on ultra with AA on or anything, just visually comparable to PS3/X360. I will be doing a lot of Photoshop/illustrator things as well and might get into video editing.
I was thinking maybe I could hold out on going quad core for a couple years until Macbook Pro lines get it at a reasonable price then I can just use the iMac as a gorgeous led and media hub in the background as I do my work on the Macbook Pro.
I've seen the benchmarks, but how does it work out in real world situations?
What would having Quad cores do for me except help me handle files/render a few seconds faster here and there? I'm sure it's a tremendous boost in things like encoding but how would it help when it comes to image editing?
Is the 4850 a huge bump in specs compared to the 4670? Is the performance gap similar to going from 9400 to the 9600?
Mac Pro :: Won't Work With ATI Radeon 2600 XT Fan Noise
Sep 29, 2008I just received my new Mac Pro on Friday - it shipped with 10.5.4 installed. After looking at some of the new features of Leopard (had only used Tiger previously), I installed all the available updates -- these were:
Mac OS X Update 10.5.5
Aluminum Keyboard Firmware Update 1.0
Java For Mac OS X 10.5 Update 2
iTunes 8.0
Digital Camera Raw Compatibility Update 2.2
QuickTime 7.5.5
Remote Desktop Client Update 3.2.2
Front Row Update
All the updates were successful and no issues were apparent until Sunday afternoon. The fan on the graphics card (ATI Radeon 2600 XT) now seems to be running at full speed, regardless of what is running. Just idling at the Desktop the fan still runs at full speed. A reset of the SMC has been done and a diagnostic as been run (no problems found). Is anybody else experiencing this? If it helps anyone, I've also posted my temps below:
Ambient Air 24.0C
CPU A Temperature Diode 34.0C
CPU B Temperature Diode 35.0C
CPU C Temperature Diode 35.0C
CPU D Temperature Diode 35.0C
CPU A Heatsink 32.0C
CPU B Heatsink 32.0C
Hard Drive Bay 1 28.0C
Hard Drive Bay 2 26.0C
Hard Drive Bay 3 27.0C
Hard Drive Bay 4 27.0C
Memory Bank A Point 1 35.0C
Memory Bank A Point 2 33.0C
Memory Bank A Point 3 34.0C
Memory Bank B Point 1 35.0C
Memory Bank B Point 2 37.0C
Memory Bank B Point 3 35.0C
Memory Module A1 48.0C
Memory Module B1 48.0C
Northbridge Heat Sink 38.0C
Expansion Slots 35.0C
Power Supply Location 1 46.0C
Power Supply Location 2 40.0C
Also, I did some reading and it seems that this issue has happened to others after they appllied the 2600 XT update from Apple. The update put their firmware at version .252. This is the version that is already installed on my card.
What I don't understand is that why for two days the fan never ran at full speed. It just suddenly started happening Sunday afternoon while I was burning some data to a DVD - the fan hasn't slowed down since.
IMac :: Common Denominator With Lockups For 4850 ATI Version?
Apr 18, 2009I don't mean to start a new Thread but I think this one could really pinpoint the problem if we could get some good feedback on this. What is the Common Denominator (besides having the HD4850 option) that could be causing the lockups that some people are having.
Examples Is everyone who is experiencing lockups :
1.) Installed Boot Camp and using Windows with this HD4850 option?
2.) Do you use Safari exclusively and not FireFox?
3.) Does it happen only when Surfing ?
4.) Does it happen only when playing a certain game like WOW?
5.) Does it happen only after you been using the iMac for a few hours?
so on. . .
See my point? Write down or make yourself notes to as what you were doing exactly when it locked up? Reply to this Thread and lets figure this out. It will be must easier if everyone could put their situation in this Thread and maybe we can get to the bottom of this.
IMac :: 27 Inch Quad Core I7 HD 4850 Temperature?
Nov 18, 2009I just wanted to share what's been going on with my i7 which I received last Friday. Immediately I was curious about what sort of temps I was going to be running so I installed Temperature Monitor. At idle my graphics readings hover around 40C. However, when playing Warcraft 3 my Graphics Processor Temperature Diode reaches up to 84C.
I don't really know what temps are acceptable, I was just wondering what other i7 HD4850s out there are running. To deal with this seemingly high temperature I installed smcFanControl and boosted all fan speeds by 50%. Noise doesn't seem to be proportional to fan speed at these levels so no probs there. Now I run at 64C at load and I am at peace with that.
Shouldn't the OS be increasing fan speed on its own?
Would like to know what you guys think and observe in your i7 machines
Mac Pro :: Won't Work With Display 2008 W / Radeon 2600
Jul 10, 2009I have been having an issue with my display lately and think it might be because of my graphics card. The display shows a "tail" of whatever is on the screen. So if you are looking at an edge of a window, that window edge will trail off to the side, creating a sort of ghost image. So I tried disconnecting the monitor and I plugged it into the other slot. That seemed to fix the the "Tail" temporarily. But, it made certain portions of the screen blurry. There are literally blurry patches. So I tried switching the connection again, and it just moved the blurriness.
Also, this is my second ATI Radeon HD 2600! Could it be a graphics card issue and if so, should I switch to the Nvidia option?
OS X :: Won't Work With ATI Radeon HD 2600 / Screen Goes Dark
Aug 30, 2009I have been having this reoccurring issue on just one of my screens. My right screen/main screen on my Mac Pro 2.8GHz seems to go dark on me, only in a few programs though. Safari and Lightroom mainly as those are the ones I use mostly on that screen.
It seems to happen once in a while, when it has been running a good bit which is why I thought it was the video card, too hot or something.
