  1. Thank you very much, that seems to be the hint I needed. I have modified AGPM according to the instructions found on rampagedev, but I still could not manage to get the kext loaded. I have been trying several SMBIOS (every time modifying the kext accordingly) with no success though.
  2. Well, I have a rather old graphics card, an nVidia 480 GTX, which although still serves me very well as I do not game. I do use Cinema 4D, and so performances on the viewport (which could be referred to the Cinebench GPU score) are very important to me. My GPU scores a respectable 82.23 on Windows 8.1 , while a meagre 28.54 in OS X. I have installed the last nVidia Web Driver, and in Clover Configurator I have checked "inject nVidia". Then I have nvda_drv=1 on my boot arguments, yet nothing helped to solve this problem. QE is working well, except few random times when invoking launchpad. In the past I had another installation, not with clover, and, gpu-performance-wise, it was performing better than this, so I am sure it is just a question of configuration to solve the problem. The rest of the system is a 2500k, 32 GB Ram on a Gigabyte z68mx-ud2h-b3 , SMBios is iMac12,2. Thank you in advance!

    Memory issues with 32GB on z87 and z97

    I can't tell how common these problems are, although I had a similar experience with RAM related problems on a Gigabyte motherboard as well. In my case the motherboard is a ga-z68mx-ud2h-b3, which RAM capacity I maxed out with four Patriot RAM sticks. At first I tried to over volt the RAM, up to 1.64V, without results. At the end, I "solved" the problem lowering the RAM timings, from the original 9-9-9-24 (for which those modules are certified), to 11-11-11-30. I hope a way or the other can help you as well!

    Workstation GPU on Yosemite

    You are right, I was assuming X99 to work with Yosemite, which may cause instead several problems as well. Yes, the 2013 MacPro is not expensive for what it offers, and I am anyway thinking about a similar price range for my eventual build. The point is that it does not offer what I exactly need, as I would prefer a single GPU with plenty of VRAM. The applications I use (like Maya) would greatly benefit of a FirePro Wseries compared to Quadro or GTX 780Ti or Titan, while the rendering software I have chosen, Maxwell Render, is CPU-based and it would doubtless speed up thanks to the double threaded 8 cores of the 5960X. To buy the components I exactly need and to work in Windows would be then another option, although I really like OS X, which I have been using for years both on legit iMacs, MacBookPro and hackintoshes..

    Workstation GPU on Yosemite

    With X99 arriving soon, I am thinking about building a hi-end machine equipped with a 5960X, lots of RAM and a workstation GPU, like an AMD FirePro W7000 or a newer W8100. Since Yosemite comes with new AMD drivers, I was wondering whether these cards could work OOB or with minor tweaks to the kexts. It will be quite an expensive build, and I am considering as well as to go directly for a legit MacPro, though there are many parts of it which I don't like at all (like that I have to externalize all my ssds, hdds). Please don't come to suggest me a gaming-class GPU instead, because it is not what I need. I found almost no informations about this on the internet, I hope someone can give me a help here! Thanks in advance!
  6. The problem seems to be solved, although I am deeply unhappy with its solution. The memory is sold as 9-9-9-24, but if you pair two kits there is no guarantee of such performances. In order to install two identical memory kits and keep the system stable, I had to downgrade the timings to 11-11-11-30. Needless to say, I do regret for buying Patriot RAM and I discourage everybody to go for this brand.
  7. I have been very busy with my work so for a while I simply left my hack as it was... but then, under an extensive use of performance-demanding applications under Windows (7 Ultimate, 64bit), I started experiencing crashes of applications and sometimes of the Operating System too. Maybe due to a different memory management, the problems were much more bearable that under OSX, yet I couldn't accept the random crashes of some applications crucial for my workflow. So I recollected about the tests with the different RAM configurations I did for OSX, I simply removed one module of RAM... and voila! All the random crashes disappeared also under Windows. So what I can conclude now is that the problem is not OSX-related, and not even with the RAM itself. I guess it is my motherboard to have somehow problems when I put all the modules on it. I mailed the support of Gigabyte, I hope the can reply to me. I tried several configurations on the BIOS too, activating and dis-activating the XMP (which is supported by these RAM modules), but the problems disappear only physically removing at least one of the RAM modules.
  8. Hello, thank you for your reply. Since updating to UEFI bios, I have not been using DSDT anymore. However, today I performed several experiments. My RAM consists of two 2x8GB kits. So I tried the first kit in the 1-3 slots, then 2-4 slots. Then repeated the experiment with the second kit. In the 16 GB configuration, the system worked fine. I then added another module, and again with 24 GB I didn't have any weird behavior of the system. But then, adding the last 8 GB causes the system to be absolutely instable, with app crashing at launch and the system freezing soon after.
  9. If you can, it would be worth trying installing different RAM modules, I had similar issue due to a non compatible RAM (which works great on Win though).
  10. I agree with you that it is a waste spending time due to these problems, but I now live in Japan and I cannot have the RAM changed unless I can proof it is defective, which seems not... The BIOS is the latest version, UEFI U1E.
  11. My build was a i5 2500k on a Gigabyte Z68MX-UD2H-B3, 8 GB RAM Corsair (9-9-9-24), GeForce 480 GTX. It was very stable running Mountain Lion 10.8.4, but for 3d rendering I needed more RAM and a faster processor. First, I bought 4x 8GB of Patriot RAM PV316G160C9K (9-9-9-24), maxing out my motherboard's capacity, and that was when all my troubles started... The system immediately became unstable, and I thought proceeding with a clean-installation. However, the installation process was always failing. At first, I thought the problem to be with the usb stick, so I tried different ones, and connecting them to different USB ports. Every time it was a failure, with the installer randomly reporting errors. I decided to install back the previous Corsair RAM, and I went through the installation without any issue. I then tried to replace again the RAM, and now I am writing from the 10.8.4 with the Patriot RAM installed, however I am getting weird app crashes: notes crashes, system preference crashes... and I might get a reboot anytime. The weird thing is that I have executed the memtest utility from memtest.org and it did not report any error. The RAM itself seems working very well under Windows, where I stress it with rendering occupying around 30 Gb or RAM for many hours and the system keeps being stable. Is it reasonable that the RAM has somehow a compatibility issue with ML? Any clue to solve this eventually? Thanks in advance.
  12. One step forward.... Since BDUtility does not give me the access to the content of the partition containing ML installation, I have installed the bootloader on a 1 gb stick, then restored the ML installation to another usb stick. So, I could access to the latter and I have deleted the kernelcache reference from the Library\Preferences\System Configuration\com.apple.Boot.plist Now I do not have the previous error anymore, yet I am stuck at "driver error". Edit: I manually needed to put the Extensions folder into the Install Stick... added several kexts too but I get the error in the image:
  13. I am trying to install ML from a 8 GB usb drive that I have prepared under Windows 8 with the Boot Disk Utility instruction I have found here, under the Developer section (clover bootloader). The system is a i7 2600k on a GA Z68MX-ud2h-b3 (UEFI), 32 Gb RAM Patriot 1600 CL9, Galaxy 480 GTX. The OS shall be installed to an empty Crucial SSD. After creating the usb stick though that utility, I can boot from it and in the following menu I can see the partition with ML Installation, but soon after I select it I get the error: ..............................Error loading kernelcache (0x7) Does anybody have a clue how to solve this? I cannot access to any Mac/ Hackintosh at the moment, so I have to prepare the needed USB Stick from Windows Thanks in advance
  14. I am trying to install ML from a 8 GB usb drive that I have prepared with #####. The system is a i7 2600k on a GA Z68MX-ud2h-b3, 32 Gb RAM Patriot 1600 CL9, Galaxy 480 GTX. The OS shall be installed to an empty Crucial SSD. When I try to boot from the USB to start the installation, it seems loading all the necessary kexts, but then, when the screen refreshes to launch the GUI of the installation process, I get this: panic(cpu 0 caller 0xffffff80002b7e95) and then can't perform kext scan: no kext summary BSD process name corresponding to current thread: Unknown I have tried to boot using cpus=1 or other flags, but everything ends with the same error. Does anybody have a clue how to solve this? Thanks
  15. No, I couldn't, I get the 254 error because of Disk Utility incompatibility with ISO9660. Anyway, I solved the problem relying on a Windows laptop I have.
