[cite] agrafuese:[/cite]Usually the number of cores reported in System Profiler doesn't mean anything, unless you have "cpus=1" in your boot.plist. If you run Activity Monitor and see two CPU graphs moving, then you have two cores running. Although, my System Profiler is reporting both cores and I'm running the latest Netkas version of AppleSMBIOS. Maybe that could be why you're only seeing one? Anyway, that shouldn't be any reason for your system to act up. But actually, you may want to try that "cpus=1" flag instead of the "idlehalt=0". I've heard it has the same effect, but it probably reduces performance on your machine, since you'd only be running one core. It's worth a try. Certainly wont heat your CPU up like idlehalt does.
How you getting on Agrafuese?

Well, I don't smell any smoke yet, sooooo...I guess I'm fine for now. Ask me in a couple of days, haha :D Seriously though, the temps are high, but the system has never been this stable. I was thinking...I believe the kernel I'm running (Netkas 9.2.0 w/ shutdown fix) has a speedstep function in it. I am wondering what my system would be like if I went back to the version before he implemented the speedstep. My theory is, if idlehalt deals with energy saving and turning it off helps me, maybe using a kernel without speedstep would help me just the same, and perhaps even without the heating up? I don't know if I'm on to anything, but I'll give it a try.

It sounds like I should be asking YOU how you're doing with the Intel...any persuasive words for us? :)

well although I think things got a little worse after I had installed that same kernel, but before then firefox would randomly crash it didn't at all after the idlehalt thing.

I don't want to blow smoke in anyones face but I tell you if you can afford it I'd definatly go intel. I just wish apple had partnered up with amd.

Well, there seems to be a lot of talk about it in rumor circles, but for me it'll be quicker to save money and buy an Intel than it will be to wait for Apple to cozy up with AMD. I'm still tortured by the fact that we've got these issues in Leopard, but not in the old Tiger releases. I really wish I could understand how that would be possible, but I have neither the knowledge nor the time to spend investigating it. Maybe we should be harassing Netkas instead of Zeph. Anyway, I'm doing some tests right now, so I'll be back with reports.

ok, small update:

apparently, there is a newer non-speedstep kernel by Netkas that i never knew about. i'm trying it out right now with some torrents and i'll let everyone know how it works after some hours of monitoring. i checked the idle temperatures on it, and it's waaaay lower than my previous kernel with "idlehalt=0". it's a difference of about 12 degrees. so that voids my theory that idlehalt is the same thing as speedstep when it comes to temperatures. definitely not :P so we'll see what happens.

which kernal does 10.5.2 include??? (of 9.2.0)

agrafuese 03-27-2008 09:54 AM

@mrburns05: not exactly sure. i think rev1 uses the original 9.2.0 non-speedstep kernel that netkas first released. i don't know which one rev2 uses...possibly speedstep kernel with shutdown fix. the kernel i am using right now is neither of the two. and while i'm here, how about an update:

the newer netkas 9.2.0 non-speedstep kernel didn't help me. i've been running torrents for about 5 hours now and the jerky mouse is back. so it looks like idlehalt=0 is the only solution for me...although, the +12 degrees on my CPU that it brings is definitely not fun or exciting. so once again, case closed for me with no "real" fix. just a "hot" fix ;)

mrburns05 03-27-2008 04:08 PM

okay now i left azureus on all night downloading a 6gb file, conections limited @ 250/300 peers, no crash!

System: using whatever comes on 10.5.2 rev1 disk

only things ive changed:

Disabled Indexing, turned off time machine, turned off screensaver, and in bios set cpu fan from 90% to full speed ( i believe at idle im around 32-33 Celcius)


I am over clocking (64 X2 3800+"2Ghz" OC'ed @ 2.2Ghz) DDR400 running at 440mhz

Hi All, Does anybody actually have a full working leopard install on AMD, ie without the bugs listed here. My system randomly crashes using torrents or just heavy workload. i have tried all suggestions here and on insanelymac to no avail , although the cpu=1 is the closest to a fix for me (takes about 8hrs to crash). Is there any point continuing on the AMD platform for Leopard or should i just get and Intel setup. It would be a shame to go Intel given all the hard work done by Zephyroth and others, but for me i cant live with random crashing and the mad mouse problems.
