Overclocking in Mac OSx (Mountain Lion)

[ebkevinlee]

Thank you nate and ToastyX! I have it running at 84hz and I do notice a difference.

Thanks again.

Here's my settings and they work at 84Hz. I only checked the box to override the frequency range and then created a custom resolution:

120Hz would look amazing in OS X.

It really would. I'm trying to hold out on installing Windows. Thanks for the pic. Btw, what are your hackintosh specs?

[NateZ28]

I'm dual booting with Win 8, for gaming. I have:
i7 2800k Overclocked to 5Ghz
670 GTX
8 GB of DDR3 1600
Western Digital Black 1 TB drive.

I really want to Try OS X running off an SSD. That's my biggest performance limitation now.
Someone help us get 120Hz running on this please.

I'm currently running OS X on a Samsung 840 Pro, and it's amazing. I highly recommend the switch. Looks like a great hackintosh system...it'll be an ever better experience with 120hz . I think we'll have to get our hands on an Nvidia driver for mac before we see any refresh rates past 84hz.

Great news for anyone who wants to remove artificial driver limits in OS X.

I made a patch that removes the 165 MHz pixel clock limit. I can now output 3840x2160 @ 31 Hz from HDMI on my 15" RMBP.

I will be releasing it soon. :-)

Has anyone had any success with getting past the pixel clock limit? I'm dying to get my IPS monitor to run past 84hz refresh rate!

I think he released the patch here: https://code.google.com/p/mac-pixel-cloc...umentation
