Hello.

I have a strange problem with my GT240 on SL (10.6.5). Actually everything works like changing resolution, 25fps at Cinebench test... and the graphic card is shown right in system profiler. But some desktop animations feel a bit laggy. For example expose, or the animation of the application-Folder coming up from the Dock. Also some web pages feel laggy when scrolling. The strange thing is, after the monitor goes to sleep and wakes up again, then suddenly everything is working very smooth and it stays like that until reboot. Also when the computer just booted, then the graphics are giong fine for about 10-20 seconds, then they turn into this laggy feeling. There is also another way to put it smooth for a short moment... If i start iPhoto, put one photo to full screen and scroll very fast through the photos by holding down one arrow-key, it changes. It scrolls quite slow for about 2 sec and then there is some kind of graphic-boost... the images are suddenly giong very fast and after this moment also the Desktop graphics go very smooth for about 20 sec.

I used [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]+[url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] for install and I already tried the nVidia driver update from the tonymacx86 website.

What can I try to solve the problem?

 

Thank You!

Sounds like malfunctioning video card power management.

 

Post your CPU model+motherboard chipset and the contents of your /extra/smbios.plist.

 

I use an GA-P55A-UD4 Board with an i7-870 CPU

 

smbios.plist:

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<key>SMfamily</key>

<string>Mac Pro</string>

<key>SMproductname</key>

<string>MacPro3,1</string>

<key>SMboardproduct</key>

<string>Mac-F42C88C8</string>

<key>SMserial</key>

<string>G88451235J4</string>

<key>SMbiosversion</key>

</dict>

</plist>

 

Thanx Jonas

Does this help to lacate the issue?

Yes, it does. Did you do any forum searching using the above information?

There are plenty of posts about how to tweak nvidia graphics card power management, how it works together with your model identifier etc etc.

 

Post the contents of /Extra/Extensions as well.

 

Since you're using [url=&quot;http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/&quot;]#####[/url], you should ask for help over here:

http://tonymacx86.com/ (follow links to the forum).

 

Your MacPro3,1 smbios.plist is missing a lot of stuff. Replace it with this (add your serial if you like)

http://www.insanelymac.com/forum/index.php...t&p=1609905

 

Upgrade to Chameleon 2.0 RC5.

In Extra/Extensions i find the following:

 

ElliottForceLegacyRTC.kext

EvOreboot.kext

fakesmc.kext

JMicron36xATA.kext

JMicron36xSATA.kext

LegacyAppleRTC.kext

NullCPUPowerManagement.kext

NVEnabler 64.kext

 

I think the new [url=&quot;http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/&quot;]#####[/url] contains this Version of Chameleon, so it should be installed.

 

I did ask for help at the tonymacx86 forum, but nobody answered, so I tried here.

 

So what exactly is missing in my smbios.plist? I can´t find anotherone with your link...

 

But thanx for care so far!

 

Cheers Jonas

See for yourself.

I can´t find anotherone with your link...

Really? Here it is again:

http://www.insanelymac.com/forum/index.php...p;#entry1609905

The contents of the codebox is a MacPro3,1 smbios.plist.

 

Anyway, I don't know if MacPro3,1 is the best model identifier to use on a system with a Nehalem CPU. The MacPro3,1 has a Harpertown/Penryn Xeon CPU.

 

You should do some research.
