hars Posted December 16, 2013 Share Posted December 16, 2013 My system:Z87M-D3H (Bios F8)Intel 4770kGeforce 8800 ultra16mb RAM (G.Skill ripjaw)Sandisk Extreme II 120gb SSDTP Link wifi cardI have successfully installed Mavericks on it although it did randomly freeze a few times on OS setup, it took me about 5 tries until I finally completed it - that can't be good right? Used these bios settings: 1. To access UEFI Setup, press and hold Delete on a USB Keyboard while the system is booting up2. Set to Optimized Defaults.3. Set X.M.P. Memory Profile to Profile14. Set XHCI Mode to Auto not Smart Auto5. Set XHCI Hand-off to Enabled6. Set EHCI Hand-off to Enabled8. Set Intel Processor Graphics to Disabled9. Set SATA Mode Selection to AHCI10. Set PCIe Slot Configuration Gen3 11. Disabled onboard graphics 12. Turned off anything that wasnt being used I then installed Mavericks. Installed 4 kexts as per another thead on this forum and chimera. I just get random freezes. They happen if I open Safari or open maps pretty much immediately. The system won't run for longer than 4-5 mins and then the mouse just stops working. I can't see anything in console that seems to indicate a problem... I have tried: Installing NullCPU Different hard drive Onboard graphics and removing the 8800 removing the TPlink wifi card Disabling onboard audio increasing memory voltage to 1.6 (also tried 1.7) installing via myhack and removing the recommended kexts installing via tonywhatever + multiwhatever (dont hate me, I'll try anything) installing a DSDT from a thread on this forum The only thing I havent tried is replacing the RAM and replacing the motherboard. I will hopefully get a couple of RAM sticks from a friend to try tonight but if there's anything you guys can think to try I am all ears and would greatly appreciate it. It's been a week of pure frustration. I think the main reason it's so frustrating is seeing all of the successful builds with the same hardware I have! Thanks!

hars Posted December 16, 2013 Author Share Posted December 16, 2013 Well, it's not the RAM - I went to the shop and bought 2 sticks of corsair - same deal. Before I try to return the motherboard is there anything you guys can recommend I try to fix it? Link to comment Share on other sites More sharing options...
styrian Posted December 16, 2013 Share Posted December 16, 2013 If nothing is wrong with your PM, try to remove the TP link wifi. I have tried myself some times ago to get a PCI version of a TP link wifi card, with an under OSX used chip, without success to work . Have fun.

hars Posted December 16, 2013 Author Share Posted December 16, 2013 And I thought I had tried that!! I read your post and thought, f^&k it, I'll try it again and only removed the Wifi card - no crashes. I have yet to try ethernet, perhaps it may come back but I'm really hoping it doesnt. My wifi card is a TL-WN951N - has anyone got one of these working? If not, can you suggest a wifi card that just works OOTB? Thank you so much Styrian Link to comment Share on other sites More sharing options...
styrian Posted December 17, 2013 Share Posted December 17, 2013 I have this one oob working since 10.6 without any problems til 10.9: D-Link Wireless N DWA-556, 300 Mbps. I think, that it has nothing to do with the vendor himself, it seems to be in any case the PCI-bus version, that is causing the freezes on OSX. Have fun.
