Trouble with Radeon 5770 in Mac Pro 3,1

Ever since I put an Apple supplied Radeon 5770 in my 2008 Mac Pro (3,1), I've been getting random system hangs. The hangs have generally occurred when using Safari or Mail, though yesterday I got a hang when I tried to loan a Juniper client to go VPN. I see a "flash" just before the hang. I have run Apple Hardware Test (extended)and Tech Tools Pro and can find no problems in the card or the Mac Pro. I've been looking also at the system logs but can't find anything definitive. I was running an ATI 3870 before this and never had any problems, which leads me to think it's the 5770. Can anyone give me a clue how I might pin down the problem further? Thanks.

2.8 GHz 8 Core Mac Pro, 2.53 13" GHz MacBook Pro, Mac OS X (10.6.4)

since MAC OSX 10.6x I observed very frequent random hangs of Safari together with Mail. It often happened just after system wake up. Followed a restart required. I have done almost everything I could found out in tech supports, or chats. Nothing helped untill now. Although I use Belkin 7x USB hub (connected to one iMac port), with various current consumpting devices attached, I never connect external power supply to the hub. All hardware basically worked well. Just foe fun, two month ago I joined the hub to external 5 V power supply and mirracle happend! Two month I am living without any hangs and restarts. I do not any idea how Safari, or Mail both checks slightly overloaded USB port, I can only say, I just solved my big problem.

Start your own thread rather than try to jump on and expect answers to your own questions buried here.

To anyone who hasn't and won't - all I can say is Disk Warrior works and #1 for ten years at fixing disk directory and some of the odd behavior and should be mandatory.

This IS a Mac Pro forum, not iMac, so if you have a question about hubs and 10.6.5, maybe the Using Snow Leopard forum section.

No joy with Apple, so they just took my $250 and ran with it. Kinda short-sighted if you ask me because it eliminates a 27 inch Apple LCD monitor purchase. With Apple's growing tendency to only support their latest and greatest, this makes this the last Mac Pro I'm going to buy.

For anyone buying a 5770 to use with anything other than the 2010 Mac Pro, best to buy it somewhere else. Several other vendors are selling it and they won't refuse a return because it's not the "supported" machine.

Sorry to hear about your result.

Applecare told me Customer relations was a hit or miss. Maybe the person that took my case was in a good mood that day?

I turned my back, and my Mac Pro, into Windows workstation, and just for testing and playing with OS X from time to time, out of the same limitation and frustration.

A pair of 5770s work in Windows, and so I presume will your 27".
