copperboy Posted April 24, 2013 Share Posted April 24, 2013 [updated]: I am thinking that Apple is doing something special to make the graphic performance of hackintosh staying half. I don't have many cards to prove this. If you guys are interested, please post CUDA-Z screenshot compared to CUDA-Z in Windows. CUDA-Z can be found here: http://cuda-z.sourceforge.net/ [Old Post] I thought I had built a perfect mackintosh, but I was wrong. The GPU kept running at half speed I changed smbios from MacPro 3,1 to iMac 12,2, and I noticed that AppleGraphicsPowerManagement.kext was loaded, but the GPU was still running half speed no matter I kept AppleGraphicsPowerManagement.kext or had it removed. Please see the pictures. Performance in Windows 7 is much higher than that in OS X. === Software === OS X: Mountain Lion 10.8.3 Method:Un1beast + Mu1tibeast + DSDT CPU Speedstep: Perfect Sleep, Wakeup, Restart, Shutdown: Perfect LAN, Audio: Perfect (Yes, even recording from mic) === Hardware === Gigabyte GA-EP43-US3L Pentium Dual Core E6300 Nanya 2GB DDR2-1066 *2 Gigabyte GeForce GT240 with 512MB GDDR5 WD 320G SATA HDD Link to comment https://www.insanelymac.com/forum/topic/288112-hackintosh-gpu-half-speed-proving-needed/ Share on other sites More sharing options...
copperboy Posted April 24, 2013 Author Share Posted April 24, 2013 I re-flashed the bios of GT240, nothing changed. I removed AppleGraphicsPowerManagement.kext in order to keep the gpu running at full speed, but it kept half of the speed it should be. I edited the plist file in AppleGraphicsPowerManagement.kext, the problem still exists. I am thinking that Apple is doing something special to make the graphic performance of hackintosh staying half.

Rogiervd Posted April 26, 2013 Share Posted April 26, 2013 Mine isn't running as fast on my ML drive as on my windows. But it isn't so noticeable like your's. http://postimg.org/image/l40o2s2jl/ http://postimg.org/image/wp363pn0t/ Don't know how to attach it like you did.

copperboy Posted May 7, 2013 Author Share Posted May 7, 2013 Congratulations. Your GPU works just right both on Windows and Mac. I think it might be the problem that GT240 is not compatible enough with OS X. Mine isn't running as fast on my ML drive as on my windows. But it isn't so noticeable like your's. http://postimg.org/image/l40o2s2jl/ http://postimg.org/image/wp363pn0t/ Don't know how to attach it like you did.
