Extremely Fast CPU Clock

31 December 2013 - 11:41 PM

Hey everyone,

 

Specifications:     Aspire V5-473G-6814

* Intel i5 4200U 1.6GHz with Turbo Boost up to 2.6GHz

* Geforce GT 740M (2GB) Optimus with Intel HD Integrated

* 8GB DDR3

* Qualcomm Atheros AR5BWB222 Wireless Adapter

* Realtek PCIe GBE Family Controller Ethernet

* Synaptics Touchpad

 

So the laptop came with Windows 8 pre-installed, and I partitioned by shrinking the existing partition and installing Mavericks 10.9 using Chameleon using a flash drive with the patched kernel for Haswell to prevent the kernel panic from occurring. Mavericks was installed successfully and could be booted into using Legacy Boot and Chameleon using the -x flag to boot into safe mode as the Geforce graphics card prevents the OS from booting. Upon the first boot, all of the graphics kexts were deleted to allow boot without the -x flag. It was now possible to boot with Chameleon into MacOSX. I was told to try out Clover as a bootloader which allowed a UEFI boot. 

 

By using Clover the resolution and QE/CI for the Intel Graphics was fixed and I was able to boot into both Windows and OSX from the boot menu without breaking neither of the installs. The only problem is that by using Clover the clock of the CPU is running extremely fast (This is seen by the clock running for a minute every 5 seconds). This makes it extremely hard to use the system as all keystrokes are being input many types in a second. The graphics become extremely glitched and the entire system becomes unusable.

 

Since Clover is relatively new for me I haven't figured out how to use much if it yet, and I haven't seen anyone else having the same problem that I have.

 

I would also need to disable the Geforce in the system to save battery life, get audio, ethernet, and maybe wifi running as well with speedsteps and sleep support, but initially I would like to solve the problem of the fast clock.

 

I've also noticed that in Clover the specifications of CPU might be incorrect but I am not sure.

 

Anyone? All and any help will be appreciated!

Thanks and have a Happy New Year!
