idlehalt=0
totally fixed my system apart from temperature issues, but I decided to go intel anyway, its just easier!

Hi lanxxx, I tried idlehalt=0 but my system would reset itself after 30, 50 mins. mouse would freeze then the busy cursor then mouse would dissapear then i would get the spinning logo on desktop and after a minute or so system would reset. so far ive had best results with the cpus=1 command (still results in reset but atleast i can use it for 4-5 hours). Do you know if this problem is purely AMD related as i dont want to buy all intel to hit the same wall again..

AMD OS X has been fun though..

As far as I know its only amd, I wonder if your system was overheating with idlehalt=0 sounds to me like that might be the case. I now have a gigabyte ga-p35-ds3l and I can tell you everything is spot on the only "negative is two channel audio" other wise, everything seems perfect, updated using software update etc etc.

If you think your system might be overheating then I found this temperature monitor

Hi lanxxx, Thanks for the link, although it only shows temps for my hard drives..with the cpu=1 command my system has been running since 9am this morning uk time. so far my uptime is 5.3 hrs with no probs..still gonna look at intel boards and cpus though..

Yeah, that app doesn't work for AMDs...tried it some time ago.

So Ianxxx, you went with the DS3L??? I thought you were gonna go with that other cheapo board? That's good news though, because that's the board I want. Glad to hear another account of the DS3L working great. IMO, 2-channel audio is fine. It's all I use. Besides, I've never had anything more than that with my AMD anyway!

Oh, but AMD users may still have a fighting chance to have a stable system! Did anyone see that JaS is back on the scene?? Check it out: http://forum.insanelymac.com/index.php?showtopic=92524

I was all smiles when I read the news, but he wont be making an AMD release for quite some time it seems. Still, it's something to look forward to!

Are you OC'ing at all? If so, try setting everything in your BIOS to default and then try idlehalt=0 again. In my case, I have no more headroom for any kind of tinkering with OC because if I did it, my system would definitely fry. At this point, I'm at about 52 degrees at idle and I'm worried enough about the ambient temperature going up in my house. :\ I may even have to look into more cooling - if I don't get an Intel system first, that is. Oh, and also try not using forcedeth.kext, just to rule it out. Then let us know how you're getting along.

Hi agrafuese, i dont overclock my system so bios is set to defaults, cooling shouldnt be a problem in the antec case i have there are two big 3 speed exhaust fans right next to the cpu. i cant check cpu temp as i havent found a proggie for it, but if i open system and touch the heatsink when running its cold to touch (i know its stupid sticking your fingers in live hardware, so i dont recommend anybody doing this). my record uptime has been 8.5 hours (not good for me).

i am at a loss , will keep researching and testing and let you know how i get on

P.S upon checking i dont have forcedepth.kext installed in extension folder,(isnt forcedepth for nvidia based gfx and network) if so my gfx are ati and network is gigabit.

ah yeah, forcedeth is for nforce lan. very strange...i haven't a clue as to why you're experiencing those issues. we should all just have a "switch-to-intel" party. anyone in? i'll bring the chips and salsa

I don't want to stress much about this, but I had the same issues as you with torrent and amule and now I'm 3 days stable 24/7. I founded that the APIC setting in BIOS was the matter. Plus I set the IRQ not being assigned automatically. I think this is a problem related to 2 core AMDs. Nobody told me to do this, but after month of trying everything possible this was what kept me from buyng another system. I also used the idlehalt=0 fn=3 parameter.

so are you still using idlehalt=0 now? and what does fn=3 do?
what did you do with your APIC setting? on, off, ?
