CInebench OpenGL is heavily CPU-biased. Don't use it, or at least don't think it means anything other than you have functional OpenCL.

No. I'm using iMac late 2013 (with Clover).

As far as I know, EA244uhd is a typical MST display. I wasn't sure if what my monitors shows in the menu (3840 x 2160 @ 60Hz) is really true. But interface operations, mouse cursor movement are absolutely smooth. Ocean Wave benchmark shows something like ~59... fps (almost 60).


It means one of these two options:

1) depending on MST implementation, MST may or may not work with NVidia or stock drivers;

2) EA244uhd uses SST.


By the way, Anand says that EA244uhd uses MST:

"One difference with the NEC EA244UHD compared to other UHD monitors so far is that it defaults to MST being enabled for DisplayPort 1.2"


Read just below that--it uses SST whenever it detects a problem with MST. You do not have working MST in 10.9.5.


Great to hear Rominator!

In Topic: Ozmosis

I have read the first 50 pages or so and am running a modified ozmosis BIOS on my ASUS X79, but have some questions that have hopefully found answer in the pages since then: 


1. Is there any way to alter an ASUS BIOS to allow you to write to NVRAM within the OS when the current the BIOS does not already support this feature? I have an ASUS X99 Deluxe that does not have writeable NVRAM with any of the three BIOS releases available for the motherboard.


2. If there is no way to add this module to the BIOS, is there a work around that can provide equivalent functionality?

I've just connected a new NEC EA244uhd to my hackintosh system with GTX 760 video card. Three OS X versions were tested - 10.9.4 (web driver), 10.9.5 (native and web driver) and 10.10PB2 (web driver). In all cases HiDPI mode @ 60Hz worked perfectly with no additional patches/hacks. 


The key to these problems are the actual monitors chosen. 


MST is not working under OS X in 10.9.X or 10.10 so far with stock or web drivers. Until Nvidia drivers enable MST you will not be able to get 60Hz @ 4K with an MST only monitor.


The sidestep is to make sure that you purchase a display that supports SST instead. The Samsung U28D590 is one such display, as is (apparently) the NEC EA244UHD.


As far as IPS-level displays, there are these two that *appear* to be SST, but the lack of widely available North American releases make it difficult to confirm:
