Unless your main workflow is running benchmark, or copying large files to / from SSD. So, the sequential read / write speed is quite irrelevant most of the time. The difference is well within normal error, and actually negligible. The boot time with a SSD installed via a SATA 2 is almost identical to a PCIe SSD. SATA 2 bandwidth is not limiting anything. Even PCIe SSD cannot achieve >200MB/s for random 4k read / write.

I just get a cheapest unknown brand 120G SSD to speed up the OS and apps loading in Windows (small files read write). I think it depends on what you use it for. If you get AHCI mode enabled successfully, installing MAC Fan Control is a must. With the absence of sensor, OSX assumes that the sensor is faulty and ramps up the above Hard Disk fan to full 6000 RPM as a safety feature. The only way out would be a fresh Windows install.Īpple has custom sensor over their stock hard drives to control fan based on the disk's temperature. This patch can completely break Windows on unsupported systems. People are free to try this tutorial out on their other models but do that on Fresh Windows install where there is no user data or important documents. Display falls on inbuild Intel HD graphics which has poor performance. These iMacs and MBPs cannot run correctly under EFI mode due to missing display and Audio hardware. OP had mentioned, this tutorial works 100% on 2011 iMac and MBP models which have Sandy Bridge CPUs. Under EFI mode, you will have AHCI mode as default and Sleep function will also work. I read that most Mac Pros can be booted directly into UEFI mode by pressing some key combination at the time of booting.

I am not sure if your Mac Pro 5,1 is supported under this. I guess I'm not seeing a huge difference between what iMac users are running and what I am running, both intel chipsets, same hard you manage to get the patch running? I guess i am not sure what hardware would be unsupported? When i check system report in my Mac, it shows all the drive functioning under AHCI. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Iastor " are nowhere to be found HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV KEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci What i find weird is when I try another method to manually change the register, I do not have any of the values that they say to change from 3 to 0. It does not let me install intels latest chipset drivers. It was originally what the OP Posted (IDE) and then converted to this after I installed the bootcamp support and restarted. Thanks, no it does not, it switched to SATA after i installed the bootcamp drivers.
