Has your Radeon 4850 based iMac froze more than once?

[Tymbo]

That does it. Then I am going to send mine back. Mine should not do this. Can you answer one more thing for me? When you transferred your files over to your new iMac, did you use Time machine or Mac to Mac transfer or did you do a clean install?

I am wondering if I do a clean install if that would fix things? If anyone has a answer here feel free to jump in.

I've read posts of people doing clean installs and witness it freeze on the install!

3.06Ghz, 1Tb, 4850, wired KB+mouse, Wifi via timecapsule, Bluetooth on.

No freezes for me so far.... received mine 6 days ago, used it intensively since. Played Team Fortress 2 (first via CrossOver, but that wasn't satisfying so installed Vista with Bootcamp, runs perfect now!), used iTunes, iPhoto, copied 100Gb of files, used Safari, Mail, etc. etc. All runs very fine without any hassle.

Good luck for those who have a freezing iMac. Hope issues are resolved soon.

The only thing I haven't tested is whether it locks up on wireless. Since I don't plan to use wireless any time in the near future (if ever) I don't really have any plans to test it out. I'm quite happy using my Mac on a wired ethernet connection to my very fast home network.

I did not transfer anything over to the new iMac other than manually moving over my mail, book marks and a few other things. Most of my stuff is stored on a local network storage set up so I don't have much to move around.

So basically I pulled it out of the box, turned it on, did updates and that's about it. I've only loaded about a dozen applications on it so far (MS Office, Keepass-X, True-Crypt-X, etc).

And so far, zero crashes.

So then since you are not using wireless, and having no freezes, then the wired part is your safe net. Since your machine will not be hooked up to wireless then you may never know if yours is affected or not.

In reality this situation that you are in where you did not use Wireless might be the others on the forum that are not having trouble either. This is interesting. Good for you though since you are not having any freeze ups.

I am doing a test of bypassing my airport extreme router at this time and running itunes with visualizer at full screen while surfing the internet at the same time and so far about 3 hours into this test no lock ups. I may leave it all night and see how it goes. If it does not lock up then I would have to think it is the wireless part for sure. The question is would it be my airport extreme that is causing the problem or the wireless logic card inside the machine that is causing this? Apple should be testing this not me. I am just trying to keep from sending back my machine unless i really have to.

Got my iMac 24" 3.06gHz ATI Radeon HD 4850 on monday.
Didn't have any freezes... watched some HD Movies, played Warhammer Online under Win XP in 1920x1200 witch high quality settings and tried many other CPU and GPU stressing things under Mac OS X and WinXP...

WiFi Off
Bluetooth Off
iMac Fan Control installed

I've been thinking about getting this iMac so I can play WAR at full settings. I play on lowest right now.

How well does WAR run at max settings?

I would say it runs good, not really great but it's playable... I switched to some lower settings to get better FPS

I just had the 2.93GHz, 4GB, 4850 delivered about an hour ago. I transfered 3GB of music, played a bunch (with Visualizer on), am currently doign WoW's Download/Installer, and am downloading apps for the Mac.

All on WiFi, only been an hour, but 0 lockups so far. If it makes it through the next 4 hours, including some gaming, I will relax a little bit.

 

[VulnoX]

Ok, I have transferred about 10GB now over WiFi, been installing WoW, played a half hour of HD video, and run the iTunes visualizer.

Anyone have anything else for me to use to get it to freeze? I don't want it to, but before I hand it off I want it to be working right.

Took a couple of days before mine froze, but running the visualizer full screen did the trick the first time. Second time, I was just posting to this forum.

Alright, I wasn't running it fullscreen before. I have it on full, transferring stuff over the wireless network, and installing/downloading WoW. Fingers crossed nothing happens today... or later.

I can't say I've had a lockup, exactly, but what has happened about three times now is the mouses freezing.

I can still use Safari using keys, but not the mouse.

Forces me to hard reboot the mac.

Is this what folks mean by 'freezing'?

I'm using wifi.

No. The freeze is when the whole system locks up; no keyboard or mouse ability. To verify the hardware freeze portion, try to turn caps lock on/off. there is no change in the LED for it. The screen freezes and some people have their audio repeat over and over. The only way out is to force a power off by holding the power button on the left-rear.

 

[Sir Loin Steak]

Well, while the mouse freezing is a pain, it's a bit of a relief (for me) that I haven't had a system lockup as others are describing.

I surf a bit, download from you tube, use handbrake, google earth, mail etc., nothing that demanding I should think.

well;
after reading all these posts I was really worried, see I had just ordered a iMac 24" for my dad (73 years old) to replace his 3 year old WinTel and its delivery date is Friday 5/1, I did not want to deal with this issue.

Then, found out I ordered the entry 24" for him, 2.66Ghz w/NVIDIA GeForce 9400M graphics, so appears by not getting the fastest "hot rod" specs lucked out in this situation.
