Hello, Firstly, my system specs: ASUS Sabertooth Z97 Mark 1 Intel i7 4790K Nvidia Geforce GTX 980, reference model 16GB RAM, 1600 MHz 512 GB Samsung 850 Pro SSD (OS X) 256 GB Samsung 850 Pro SSD (Windows) LG 31MU97 (Monitor)(via DisplayPort for 4k @ 60 Hz) Side note: I will be referring to UEFI as BIOS in the following quandry. I have a bit of a problem... Allow me to get straight to the point. I have an ASUS Sabertooth Z97 Mark 1 mobo. I purchased it to start building my first Hackintosh. As many of you may know, in order for a Hackintosh to run correctly, there are certain default settings in BIOS that must be changed. I had no problems doing this initially, and therefore, I was eventually able to get my Hackintosh up and running, however due to my limited knowledge at the time, I had some clover bootloader issues that I believe to be outside the scope of this question. Just for the sake of clarity, my Hackintosh was set up for dual boot. One SSD for OS X and another SSD for Win7 64-bit. Until now I've not really had the need to access OS X which is why I was semi-content with the aforementioned clover bootloader issues, wherein the clover bootloader would actually fail to post at all despite me setting the drive where it was installed as 1st boot priority. I would always boot straight into windows. Now, I've said all that to say that to get everything working correctly I have basically decided that I will have to start over and install everything again on freshly wiped drives. As said before, I am very aware of the changes that must be made to the BIOS in order correctly run OS X. Unfortunately that is where I'm having a bit of a problem. Every time I boot up and press del and actually manage to get through to BIOS(sometimes it just boots straight into Windows even though I'm pressing del like a maniac), everything just freezes. All I see is N/A everywhere, the names of my drives, the incorrect time and date, along with some mysterious and horrible video distortion(video does not distort at windows login). Any keyboard input results in nothing, and the mouse is just frozen in the middle of the screen. I also noticed that the "BOOT_DEVICE_LED" debug light is lit up on the mobo when the BIOS is in this frozen state, although the computer boots to Windows just fine(and even OS X when I disconnect the Windows SSD). So needless to say there is no way I can change the settings I need to for this Hackintosh to work properly. It is also worth mentioning that my monitor(LG 31MU97) is plugged via displayport in a Nvidia Geforce GTX 980 reference model, on water. I shouldn't have to plug my monitor directly into the mobo when trying to access BIOS, right? Per some experiments, Ive noticed that the video does not distort when using HDMI on the GTX 980. So maybe there is something about displayport? Normally I wouldn't really care if I had to use HDMI, but I need 4k at 60 Hz pretty much all the time when on the computer, so it'd be pretty inconvenient just to have to plug in an HDMI when I'm changing BIOS settings. I don't want to overload this thread with another drawn out question, so I'll post another question here about my Nvidia Geforce GTX 980 displayport issue. Ive tried everything I know. Flashed a BIOS update(multiple times) using BIOS Flashback, reset CMOS, re-flashed GPU BIOS. I want to get the ball rolling for my Hackintosh, but it seems I'm at a standstill until I can get this BIOS situation figured out. Sorry for my long-winded question. I just don't want to leave out any details. Anyone have suggestions? Thanks in advance:) Distorted Frozen BIOS - DisplayPort->GTX 980 Not Distorted Frozen BIOS - HDMI->GTX 980 BOOT_DEVICE_LED debug light
Hello all, Here are my system specs: Mobo: ASUS Sabertooth Z97 Mark 1 CPU: Intel 4790K GPU: Nvidia Geforce GTX 980 reference model, on water RAM: 16GB 1600 MHz 512 GB Samsung 850 Pro SSD (OS X) 256 GB Samsung 850 Pro SSD (Win7 64bit) Monitor: LG 31MU97 I am having problems with my GPU(or at least I think the GPU is the problem). I am using DisplayPort to connect to my LG monitor. It is very important that I use the DisplayPort connection. I need the 4k resolution at 60 Hz at pretty much all times for the work I will be doing. Therefore HDMI wont cut it. The problem I am having, however, I believe lies with the DisplayPort. Just as an example, whenever I boot to BIOS I get a horribly distorted image(see image below). Whereas if I use HDMI, there is no distortion. As you can see from the specs above, my system is a Hackintosh, but up until now I haven't really used the OS X drive much. So much of my explanation pertains to my experience while in Windows 7, although when testing out OS X I had many of the same problems. It was not very easy setting up my GPU when I first got it. After I installed the drivers and essentials for operation, and plugged into the monitor via DisplayPort, the image on the screen was distorted and stuck on a nasty resolution of 640x480. I was able to quickly fix this by creating a custom resolution at 4096x2160 in the Nvidia Control Panel. However, the Nvidia Control Panel actually still recommends the 640x480 resolution for my 4k monitor for some reason, but only when I am plugged in via DisplayPort. When plugged in via HDMI it picks up 4k resolutions with no problem(but only at up to 24 Hz). I am not sure if there is something I can do to make the card automatically identify the LG monitor as a 4k monitor and not have to rely on software. At present I am not sure if there is anything actually wrong with the card, or if it may even be the monitor. I have no other DisplayPort monitors to test it on at the moment. So I need help figuring out a solution to this. Ive re-flashed the BIOS for the GPU with no result, but other than that I'm not really sure what I should do. Any help is appreciated.
