CloverLeaf Posted August 23, 2022 Share Posted August 23, 2022 (edited) Hello hackintoshers This is not intended to be an installation guide but rather sharing my feedback on hackintoshing hardware leftovers as my mom said. A few words... Long story short - old parts found in a box while cleaning my cabinets. I was not sure what is working and what not so I decided to give it a try. It's nearly 8 years old hardware but works great under MacOS! Hardware Motherboard: Asus H81M-K CPU: Intel Xeon E3-1226 V3 @3.3-3.7Ghz (no iGPU) + intel stock cooler Socket: LGA1150 RAM: 2x4GB DDR3 @ 1600 Mhz GPU: Sapphire HD 7750 Ultimate 1GB Fanless (1x DVI , 1x HDMI 1.4a , 1x DisplayPort 1.2) SSD: Samsung 840 EVO 250 GB PSU: Fortron ATX-300PNF (to be replaced? - NO ) CASE: Dispersed on the table (to be fitted in a new case soon) Segotep Prime-V BIOS Settings Enable: EHCI Hand-off Intel xHCI Mode Sata Mode: AHCI iGPU Memory: 64MB (if using iGPU only) Execute Disable Bit OS type: Windows 10 UEFI mode Intel Virtualization Disable: Fast Boot Secure Boot Serial/Com Port VT-d Parallel Port What is working? Everything I tested! Sleep, restart, shutdown CPU - Speedstep and power management dGPU - Fully working QE/CI , Metal support + audio over HDMI (radpg=15 used for propper GPU initialization) USB2.0 , USB3.0 Audio - ALC887 LAN - Realtek 8111 What is NOT working? So far everything is working correctly. Not tested iGPU - my CPU doesn't have iGPU so I am not able to test it. MacOS Version Current: MacOS Monterey 12.6.2 Also tested: Mojave, Catalina and Big Sur OpenCore Version OC 0.8.8 Additional Notes Kext signing is disabled so I can use chris1111's web drivers for my TP-Link T3U adapter - https://github.com/chris1111/Wireless-USB-Big-Sur-Adapter MacOS Monterey will only boot with model Macmini7,1 !!! All other OS versions will boot normally with both Macmini7,1 or iMac15,1 Please generate your own SMBIOS!

CloverLeaf Posted January 16, 2023 Author Share Posted January 16, 2023 UPDATE! System updated to the latest MacOS Monterey 12.6.2 USB Ports mapped using https://github.com/USBToolBox/tool.

My first task is to work 4 Monitors on HDMI, Unfortunately i cant use native HDMI monitors to those ports, Works only HDMI to VGA Host : HP Z800 Workstation CPU : 2x Intel(R) Xeon(R) CPU E5620 @ 2.40GHz RAM : 48 RB DDR3 MACOS : macOS Monterey Version 12.6.2 (Build 21G320) SMBIOS : MacPro7,1 GPU : Cape Verde PRO [Radeon HD 7750/8740 / R7 250E] (No IGPU) GPU Device id : 0x683F1002 -Bootargs : v keepsyms=1 -no_compat_check radpg=15 ioregistry & EFI Atteched here with 1658605270_HPsMacPro.zip EFI.zip Edited January 17, 2023 by datafeedexpert Added GPU-z image Link to comment Share on other sites More sharing options...
CloverLeaf Posted January 17, 2023 Author Share Posted January 17, 2023 (edited) Hey @datafeedexpert. I am afraid I cannot help with ports patching but hopefully some of the experts here can give us a hand ? @Allan , @MaLd0n , @Slice , @miliuco , @Cyberdevs , @deeveedee Edited January 17, 2023 by Jazzoo 1 Link to comment Share on other sites More sharing options...
deeveedee Posted February 1, 2023 Share Posted February 1, 2023 (edited) @Jazzoo Nice work! Sorry I didn't respond before. Somehow, I missed the notification of your "ping." @datafeedexpert I don't have any experience with patching the ports of an AMD dGPU. I see in your config.plist that you have a disabled kernel patch (below). Without any experience and just guessing, that's how I'd attempt the patch. I would also first attempt to get video working on the last version of macOS natively supported by your hack (a version that does not need '-no_compat_check') to eliminate variables.

deeveedee Posted February 1, 2023 Share Posted February 1, 2023 @Jazzoo - I was reading the specs of your rig and now I'm jealous. I wish my hacks had an 'Excuse Disable Bit' ! 1 Link to comment Share on other sites More sharing options...

HD 7750 Connector Patch Hide contents @deeveedeethe above Connector patch was created by my self using old RAMPAGE guide but it was not worked so just disable it,,,BTW way I am unable to show Opencore boot Picker at any of the HDMI port , while if i use HDMI to VGA converter on first HDMI & native HDMI on second port then only i can show boot picker & after booted macOS i have to use only second native HDMI monitor otherwise both screens blank / flickering Link to comment Share on other sites More sharing options...

Somehow, I missed the notification of your "ping." Hide contents Thank you @deeveedee. It was really fun to play around with the old hardware. All the components can be found really cheap on ebay now. It's amazing how smooth it works, everyday tasks like browsing, music, documents just works great! I even did a short video edit in Adobe Premiere and Logic Pro X project with 26 tracks. It was so nice! I didn't see your message earlier. I gave the computer to a friend of mine as a gift already so I cannot test stuff anymore, but if I can help with something just ping me! As I stated before GPU patching is something that I never did before and cannot help much Sorry... PS - That's how it looked like after I put it in the case: Edited February 1, 2023 by Jazzoo 2 Link to comment Share on other sites More sharing options...
deeveedee Posted February 1, 2023 Share Posted February 1, 2023 @Jazzoo I'm a firm believe in extending the life of old hardware. Nice work! 2 Link to comment Share on other sites More sharing options...

I think an 'Excuse Disable Bit' would be much more useful than an 'Execute Disable Bit!' 1 Link to comment Share on other sites More sharing options...
CloverLeaf Posted February 6, 2023 Author Share Posted February 6, 2023 Quick update from a user reported to me that he used my EFI directly on his Asrock H81M-VG4 build and it worked right away with the latest MacOS Monterey 12.6.3. All usb ports recognized correctly, sleep/wake, audio, power management, etc. For those of you interested in the exact specs - he is using Intel i7 4770 and Sapphire RX 580 4GB. I helped him with some quick fixes. Old Asrock boards, specifically H81 has the annoying finnicky UEFI and often struggles to find the EFI. This was easily fixed with Linux Live USB using efibootmgr Cheers! Link to comment Share on other sites More sharing options...
