Hi Guys,

I just bought about 2 days ago a motherboard Gigabyte G1 Sniper B5 and a processor Intel i7 4770k @ 3.5GHz. My goal here is to overclock the processor to at least 4.2GHz and I spent my entire day yesterday trying and so far, no lucky at all.

I was looking on the web about informations and how to overclock this processor with this motherboard but there is just a few posts about it.

I have updated the BIOS to the last version avaiable on Gigabyte website, the F8a that as informed by Gigabyte now has support to the "K"s processors.

Then I start my journey, under UEFI BIOS I went to Performance -> Frequency and there I have changed only the CPU Clock Ratio to 42 (the Default value is 35) and left all the rest as it is. I save the profile, exit BIOS and reboot the system.

On Windows, I have downloaded the CPU-Z and indeed the system was overclocked but after the first stress test with Prime95 the screen freezes and the system crashes.

I have tried with Clock Ratio 41 and 40 as well but in all cases the system keeps crashing.

The temperatures aren't exceed 69ºC degrees, I am using the aftermarket aircooler Coolermaster Hyper TX3.

I have no more ideas on mindabout how to proceed with this.

Do I need to change any another settings on BIOS to achieve the 4.2GHz clock speed?

If someone has the same board with the same processor and achieve any good results overclocking, could you please help me?

Thanks in advance.

Right, but have a look on this guide: http://www.guru3d.com/articles_pages/gigabyte_g1_sniper_b5_review,9.html

The guy was able to achieve the overclock. I've tried to follow those steps below:

1. Leave baseclock for what it is right now
2. If optional, increase the TDP limit of your processor to 200~250 Watts
3. With a 4770K change Turbo multiplier to 44 initially and gradually work your way upwards. With each stepp stress test the CPU with software like Prime95.
4. Increase CPU voltage, though setting AUTO might work fine, we think 1.35~1.40V on this motherboard is a sweet spot.
5. Make sure your processor is properly cooled with enthusiast grade heatpipe cooling or liquid cooling
6. Save and Exit BIOS / UEFI

But I didn't found the option to increase the TDP limit on BIOS...
