    MSI R9 270x Twin Frozr 2GB

    For sale, a MSI R9 270x Twin Frozr 2GB, immaculate condition, bought 5 months ago BNIB. I will be sending the invoice along with the GPU. I had no problem installing macOS El Capitan, Sierra & High Sierra with no patches whatsoever applied to the card. Price 130 euros, I can send photos if needed.

    MSI Twin Frozr 270x 2G

    Greetings everyone, I recently purchased a MSI Twin Frozr 270x 2G as new, and while I don't modify at all the config.plist, it is identified as AMD Radeon HD 7xxx 2048 MB and utilizing AMDRadeonX4000.kext as AMDPitcairnGraphicsAccelerator. Is there a different configuration I should be following like Inject ATI and using a different FrameBuffer? I tried using Futomaki FB, but I get black screen after the Apple Logo loader.
  3. Hi, Here is my experience with this setup: - ASUS X99/A USB3.1 Mainboard - i7 5820k processor - Radeon R9 270x - SAMSUNG M.2 MZHPV256 storage - ASUS PB287Q 4k display (Display Port connector) Since I had to go through a lot of different resources to have it working properly, I wanted to share all the info in a single place. Following the guide from http://www.rampagedev.com, and with the help from Slice, Mieze and Vlada from http://www.insanelymac.com/forum/topic/308025-no-graphics-usb-audio-after-wake/, the info from Stinga from http://www.insanelymac.com/forum/topic/309717-haswell-e-5820k-5930k-installation-guide-with-full-speedstep-working/, El Capitan USB threads from Rehabman and constant updates from Pike's blog https://pikeralpha.wordpress.com we can get a really stable build based on X99 chipset with the following features: - Speedstep working - Audio through DP - All USB2/3 ports working (USB3.1 ports disabled in BIOS) You can find a screenshot attached List of steps to be performed: Disable Serial Port in BIOS (I cannot boot the system with Serial Port enabled), disable ASMEDIA USB 3.1 controller Strictly Follow the installation guide in Rampagedev.com Follow the X99 guide from Ramapgedev (except for config.plist) for 10.10 using the following files: SSDT.aml in ACPI/PATCHED (rampagedev) AppleIntelE1000e for ethernet support (rampagedev) FakeSMC (currently using SLICE 3.x version) http://www.insanelymac.com/forum/topic/296460-amdcpumonitor-and-hwsensors-331/page-1 X99_Injector modified kext (attached) to load AppleLPC kext only (credits to PJALM) config.plist for Clover (attached here) config.plist probably has redundant info, but basically provides the following features: Rename EHC1, EHC2, XHCI in order to have USB fully working use xcpm for power management Patches AppleUSBXHCIPCI to remove usb port limit Forces a fake processor ID to enable xcpm and speedstep There is NO need for a specific processor P-states SSDT, but if you want to get no errors on boot you can create one following the details in the threads above. That's it. Attached mine, in case you want to use my configurations (47x max multiplier, 100Mhz BCLK) BIOS configuration (for my setup): Speedstep enabled Turbo states enabled Max CPU multiplier 47x as you can see from the xcpm info - I would suggest to start with "AUTO" for all CPU-related settings BCLK 100 Mhz Memory set to 2133 Mhz - If I increase memory speed to the upper 2k range or set the BCLK to higher freq. the system is very unstable and reboots without notice (this happens in El Capitan only, Yosemite works perfectly!) Other: M.2 disk does not require ANY specific action on BIOS or OSX USB does not require any specific kext apart from the config.plist patches OSX Sleep/Wake is NOT working properly - Radeon times out In order to use Display Port I had to modify Rampagedev SSDT GFX0 section from: "@0,connector-type", Buffer (0x04) { 0x00, 0x08, 0x00, 0x00 }, "@1,connector-type", Buffer (0x04) { 0x00, 0x08, 0x00, 0x00 }, "@2,connector-type", Buffer (0x04) { 0x00, 0x08, 0x00, 0x00 }, "@3,connector-type", Buffer (0x04) { 0x00, 0x08, 0x00, 0x00 }, to: "@0,connector-type", Buffer (0x04) { 0x00, 0x04, 0x00, 0x00 }, "@1,connector-type", Buffer (0x04) { 0x00, 0x08, 0x00, 0x00 }, "@2,connector-type", Buffer (0x04) { 0x00, 0x02, 0x00, 0x00 }, "@3,connector-type", Buffer (0x04) { 0x00, 0x02, 0x00, 0x00 }, In order to fake MacPro6,1 AMD FirePro300 Video card you can add the following item in clover Info.plist under the KextsToPatch section: Hope this helps!!
