eep357 Posted July 24, 2012 Share Posted July 24, 2012 Also have found that adding USBBusFix=Yes to your boot.plist will improve your scores by around 7 fps, and improve in Novabench too. Have confirmed this on a few x58 systems, not sure yet about some other mobo chipsets, so please feel free to test and let me know.

dtrvndrn Posted July 30, 2012 Share Posted July 30, 2012 Hi people, thanks a lot for the info here. Here's my experiences on the subject. I have an XFX HD6870 2GB version, GA-Z68MA-D2H-B3 mobo, i7 2600k (non-oc), 8GB RAM (clocked at 1600mhz). I used to have around 48fps/7pts in Cinebench on OSX 10.7.2, Chimera/###### (don't remember the version), SMBIOS macpro3,1, graphicsenabler=yes. When I checked again the other day I got less than half, 21fps/3pts, no matter what. Not sure at what point I did something that killed the performance but I wanted to fix it. Needed to update to 10.7.4 anyway. With this config AGPM is not running. First I updated to Chimera1.11 / Multibeast4.6.1. Same results. Then I changed SMBIOS to macpro5,1 (had to delete appletymcedriver.kext in the process to prevent KP). Results back at 47fps/7pts. AGPM running (without editing anything). Happy. Then I updated OSX to 10.7.4 and the results are back to 21fps/3pts. AGPM still loading though. Not Happy. Any ideas on this? NB: Unigine seems to run the same on all these installs... Edit : installed HWmonitor and my CPU seems stuck at 1600Mhz (x16) so looks like I have some work to do...

dtrvndrn Posted July 30, 2012 Share Posted July 30, 2012 Alright, that was easier than expected! I fixed it with ###### settings: patched appleintelcpupowermanagement & SSDT i7 and in BIOS (F10 firmware): 'realtime CPU control in OS' disabled . CPU now goes up to 3500Mhz dynamically and Cinebench stats are back to 47fps/6.5pts. * Edit: it even gets better, now getting 51.89fps/6.70pts Geekbench 32bit = 11866 Luxmark CPU = 450, GPU yields error, seems to be a Luxmark issue from what I read Oceanwave = 341.4 fps * Edit#2: toyed some more in BIOS, set CPU multiplier and turbo ratios, installed i7-overclocked SSDT. CPU now boosts up to 4.2GHz. Cinebench: 58.15fps/7.40pts (runs damn hot though!)
