Guide to Overclock Intel Core i5 4200U

First of all U series is solid on the motherboard so no *easy* upgrade for this CPU.

Things you'll need:
1. A laptop with the SAME CPU as above
2. Mac installed on you HDD
3. USB (Pref 16GB+ ) stick with install Clover inside
4. VirtualBox is *required* to install Clover
5. Unlocked BIOS version for you Laptop *CARE, do not mess with BIOS by yourself, it may brick your motherboard *

First step:
Install any Mac OS (Pref. Yosemite + ) to your VirtualBox
Install Clover on your USB *Link: http://cloverboot.weebly.com/install-clover-to-usbhdd.html
Install Mac on your pendrive with VirtualBox ( Search Google )
After all these step, boot at your pendrive and just install Mac
Finish your settings with Mac and shutdown
Finally boot Clover from USB and adjuct your CPU *Do not overclock too much is may fry your CPU*

G50-70 i5 BIOS




















Well tried on many windows platform without success and now I successful overclocked it on Macintosh Yosemite

Yes, U series overclocked successful!

I didn't had the time and now am at work so propably in about 3-4 hour's i will upload the guide.
Awesome! Really interested in this guide.

Nice guide, and benchmarks/does it feel any faster. I will try this over the weekend (not that I have the same laptop as you, so it might not work for me).

Thanks!

Actually the truth behind this is that the whole Clover overclocking thing doesn't really work. One can set virtually any value for the bus speed, which doesn't set it for the hardware but makes the system think it's running faster.

For example you can get it to 400mhz as you can see on the screenshot but in reality it's still running on 100mhz, but the system will be running terribly slow with the 400mhz bus clock.
So basically this doesn't yield any real-life improvements, just makes cheating in benchmarks possible.

First thing, it's from your CPU. For example, if you have Intel Core i7 XXXXQM you can overclock it without clover, just with XTU.
Second with clover i can set whether my CPU can double first P state (which is worth it for perfomance).
Third, yes with high cpu bus it goe's laggy!

So, "fake" bus or not Benchmark's say's the true my friend.

All best IFI5

Sorry to say, but it doesn't really work that way. I have an i7 4720HQ CPU which doesn't allow me to overclock it past Intel's +2 turbo bins limit, and it should be quite similar to your CPU.

Let me explain it - basically you are slowing down time on the laptop when you set the bus to higher values than nominal. So, the laptop thinks the time goes slower, so when it does its calculations at the same speed as always, it appears to be way faster. The reality is kinda different - the real performance is still the same - it only hinders UX because everything is proportionally slower to the percent "OC" applied to the bus.
So benchmarks definitely say it's faster, but I have a simple task for you - measure seconds in benchmark runs in Geekbench and Cinebench with an external stopwatch(don't use software on the laptop itself). You will see that there's no difference between the runs, so no real increases in performance.
Or just set the bus to say 500 mhz and check the benchamrk scores and CPU clocks - I reached 11 Ghz with my i7 and 400 mhz, but what's the point of this if the system is running 4x slower and only benchmarks show an artificial increase of 400%. 2400 fake points in Cinebench is a better result than the 6 core desktop CPU's achieve, but what's the point of this if it's fake?

The real BCLK OC would only give you 3 to 5 percent increase, but it requires a certain chipset and requires modding of the ME region to even allow it, so the amount of work to get it done is improportional to the gains. It's definitely not as easy as writing a random number in Clover options
