Ok here's an alternative step-by-step guide for El Capitan on x58a-UD3r with Clover, including working speed-stepping, sleep and better geek bench scores .
See this guide for more detailed instructions for step 3 and 4
http://www.tonymacx86.com/el-capita...-el-capitan-any-supported-intel-based-pc.html.
1. Update BIOS to FH. This is necessary to us the attached DSDT.aml and have working sleep and stepping. If you're updating from version FF or lower, you'll need to use @BIOS app to do the update as the BIOS size goes from 1M to 2M so Q-Flash won't do it. You'll need some kind of Windows install to do this.
2. Standard BIOS stuff.
Optimised defaults, 64-HPET, AHCI for all SATA controllers are the main ones.
Use the XMP profile for your memory if it supports it, clover can detect correct speeds from here later.
Make the drive you are about to install El Capitan to top of the Hard Disk Boot priority list.
**
note: if you have an SSD or other drive that supports SATA III, remember to put it on gSATA6/7 as they are the 6Gbps ones. Also, if you're not using eSATA, and nothing connected to gSATA8/9 ports, disable them both for faster booting.
3. Prepare Unibeast stick via a previous install, or another Mac. Repartition the USB stick first as MBR scheme with Disk Utility and give it a name like 'El Capitan Installer'. You'll need latest Unibeast (clover version) and El Capitan from the App Store. Run Unibeast and choose Legacy Mode as these boards don't have UEFI. If you have an older GFX card, you may need to select the appropriate 'Inject'. (See Step
2 in the guide linked at the top of this post for more details.)
4. This step may be optional, but it doesn't hurt. Copy the attached DSDT.aml to EFI > EFI > Clover > ACPI > Patched on the USB stick that was just created by Unibeast. You'll need to mount the EFI partition first using either Clover Configurator or EFI Mounter (in the downloads section)
5. Reboot and punch F12 on BIOS screen and chose to boot to the USB stick. Select your 'El Capitan Installer' USB at the clover menu. Prepare your target drive with Disk Utility. Easiest way is to 'erase' the physical disk. The default settings should be correct, but you want GUID partition and Mac OS Journaled. Name it 'El Capitan HD' . Install El Capitan. ( See Step
4 in the guide linked at the top of this post for more details.)
6. After installing and reboot, punch F12 again and boot from USB. This time select 'El Capitan HD' and follow steps to set-up El Capitan. (If you get black screen here with new nVidia card, you may need to boot with nv_disable=1 for now) Download El Capitan Post-Install Tools (Tonymac) and install Clover_v2.3k_r3320-Legacy.pkg and CustoMac Essentials.
7. Remove the Unibeast USB so as not to confuse EFI partitions. Download and open Clover Configurator. Mount the EFI partition from the HD and copy the attached DSDT.aml to EFI > EFI > Clover > ACPI > Patched. As our DSDT patches are already done in the DSDT file, we don't want clover to do anything on the fly. So on the ACPI page, make sure 'DSDT name' is DSDT.aml and uncheck everything except 'Generate PStates' and 'Generate CStates' in the SSDT section. In the Boot section, fill in the name of your default boot volume (will be 'El Capitan HD' if you followed me) and select 'XMPDetection=Yes" if you used your XMP profile in BIOS before.
8. In the SMBIOS section, click the wand, the Mac Pro garbage bin, select MacPro4,1 and make sure to shake the week of manufacture and unit number a few times to get a unique serial number. These boards have the SId bug so open a terminal window and type 'uuidgen' and hit return. Past the number it generates in SmUUID. This helps with iMessage.
9. Graphics options will depend on your card. You may want to inject Intel/ATI/nVidia for older cards, or for Maxwell nVidia cards, you'll need to use nv_disable=1 to boot until you can install the nVidia web drivers, then switch to nvda_drv=1. You can do this by ticking the boxes on the Boot page, or adding the boot arguments temporarily from clover at boot time.
10. Save and reboot. With any luck you should have El Capitan with working
Sleep / stepping / iMessage and full performance.
--- Optional ----
HWSensors: To check that the DSDT and clover settings are working properly, you'll want to download HWSensors
(
www.hwsensors.com) and copy all files to EFI > EFI > CLOVER > kexts > 10.11 except HWMonitor.app which can go in your Applications or Utilities folder. This won't work at this stage because there is another incompatible version of FakeSMC.kext in /Library/Extensions put there by Customac Essentials. Navigate to /Library/Extensions and delete FakeSMC.kext and use Kext Utility to Repair Permissions and Rebuild Cache. Upon reboot you should be able to run HWMonitor and see the CPU multipliers changing i.e. Speedstep.
Audio: I don't use onboard audio so haven't tested but apparently the Toleda script works nice. Only use Voodoo as a last resort, it's a big hacky mess.
