#2127781 Asus X99 Deluxe + 5960x - Stuck, please help!

Posted by SoundForSoul on 13 April 2015 - 06:39 PM

IMPORTANT UPDATE: I got my 5960x overclocked at 4.16 Ghz (as seen by iStatMenu only by adding a 42 cpu multiplier in bios, with a 1.2 vcore temperature but - very important, by disabling speedstep and enabling turbo. If you don't enable turbo mode, nothing above the base multiplier (30, in my case) will be recognized by clover / osx.Also, disabling Xhci got me a 10% improvement in cpu performance, but lost all the usb 3 ports ( I guess I have to install generic usb kext  for those to come back).33000 in geekbench at 64 bit with 10.10.2 with cpu temps at around 50 celsius (fractal design  s36  water cooler - awesome one !)

Just wanted to check in again about my overclocking progress... Here is what I discovered: -OS X flat out refuses to go above the base multiplier, which in my case is x30. If I don't use NCPM, it APPEARS as if it's going above x30, but it's actually not based on my identical benchmark results.-Intel Power Gadget reports incorrect readings. When it reports your clock speed in GHz, it assumes you are using a 100 MHz bus speed, so if I have my BCLK set to 125, it will show "3.00 GHz" when it's at 3.75 GHz. This happens in the Windows version as well.-The only way I am able to get OS X to successfully use my overclock is by overclocking the BCLK. Currently, I've got a 167 MHz BCLK and x29 multiplier so I'm at 4.34 GHz. Thanks @schumlav for suggesting overclocking the bus.I got my 5960x overclocked at 4.16 Ghz (as seen by iStatMenu only by adding a 42 cpu multiplier in bios, with a 1.2 vcore temperature but - very important, by disabling speedstep and enabling turbo.
