random crashes from watching Quicktime/HD video i5/P55-UD3R

[hjmm]

TonyMac - your guides are awesome!

After weeks of work, I have finally gotten to a fairly stable situation. Using BootCD method, installed SL off retail DVD and Win7 too. My GA-P55-UD3R / Core i5-750 now has dual boot OSX/Win7 - installed OSX 10.6.2, sleep works. I even got audio after installing my Mobo-specific DSDT and replacing the 10.6.2 AppleHDA.kext with the older one from TMX's web site, as recommended for UD3R.

OSX stayed up for 8 hours (light web browsing, mostly idle) - I thought I was golden.

First thing I do is to go watch Steve Jobs' iPad keynote in HD - within about 20 min, OSX crashes, hard, no warning, no messages. I tried again, and it happened again, at about the same time.

In another post, there was a recommendation to use iStat Pro to monitor CPU temperatures, which I have done. The CPU temp varies between 30-39 degrees C, which seems like it should be OK. Hard disk temp stays below 34. CPU is very lightly loaded, never above 9% busy.

In order to try to eliminate the hardware as a problem, I used my dual-boot and launched Win7 to watch the same video. It played for over an hour with no issues.

I tried to rollback to the original 10.6.2 AppleHDA - reproduced the crash immediately the first time, but the second time, it played for over 20 min.

Help!! any suggestions?

p.s. a few days ago, F5 BIOS was released - might there be any benefit?

If you go to your dashboard and add a widget, does it ripple?

If not, post a SS of your system profiler with Graphics/Displays selected.

I'm thinking that the one on there was bios version F4, since the F5 one came out recently. I think you're probably best to update to the latest bios- stability for your mobo is key. Also, did you replace your DSDT with the one from the DSDT Database? And post your /Extra folder contents as well.

I absolutely have BIOS F4. I guess I will give F5 a try, meanwhile, here are my configuration details. Thanks for your help!!



QE/CI is enabled - yes, I get ripples when I add a widget

/Extra/Extensions contain the following files:
Ev0reboot.kext
fakesmc.kext
JMicronATA.kext
PlatformUUID.kext

I did indeed get the GA-P55-UD3R custom DSDT from your DSDT database. it has a date of Jan 31, 2010 7:28am and filesize of 25kb

Upgraded to BIOS F5

I have played the entire iPad keynote successfully. Problem solved.

p.s. Is there a battery of stress tests that you can recommend to increase confidence that the system is stable?

Some people say to sleep/wake 100 times. Don't know if it's an urban legend, but there's a script on the Insanelymac forum that sleep/wakes your system 100 times automatically. Other than that, I can't recommend anything. Glad your issues were solved with the bios update!
