ASUS P8Z77-V Deluxe Overclocking

Overclocking greatly varies due to what hardware is being used and who is doing the overclocking. Always remember that no two pieces of hardware will perform the same, so our results will differ from what you might be able to get.

ASUS P8Z77-V Deluxe CPUz 1.6

The Intel Core i7 3770K utilizes a Bclk of 100MHz, under full load the Intel Core i7 3770K uses a multiplier of x35 to achieve the final clock speed of 3.5GHz. Since we are using a K series processor which has an unlocked multiplier we will be able to increase the default x35 multiplier to achieve our overclock today. We can see in the above CPUz 1.60 screen shot that with the Turbo mode engaged we are cruising along at 3.9GHz.

ASUS P8Z77-V Deluxe 'Ivy Bridge' Autotune Overclocking

The ASUS P8Z77-V Deluxe has an ‘Auto Tune’ feature within the UEFI BIOS. Once enabled the system will reboot and ramp up the multiplier and Bclk to a predetermined level. We can see in the above CPUz screenshot that we are running at 4223.82MHz thanks to a x41 CPU multiplier and a Bclk of 103.2MHz.

ASUS P8Z77-V Deluxe 'Ivy Bridge' Autotune Overclocking

When I engaged the ASUS auto tune feature I had the memory set to 1600MHz with 9,9,9,24,1T timings. Taking a look at the memory settings after running auto tune, we can see that the memory was backed down to the 1333MHz memory divider and 2T timings.

ASUS P8Z77-V Deluxe 'Ivy Bridge' Intel 3770K Overclocking

Despite our best attempts we weren’t able to push our Intel Core i7 3770K beyond 4.8GHz with any stability. We were able to boot into Windows as high as 5GHz but as soon as we tried to put a load on the 3770K the system would crash.

ASUS P8Z77-V Deluxe 'Ivy Bridge' Intel 3770K Overclocking BIOS Settings

The above UEFI BIOS screen shot shows the CPU Multiplier at x48.

The only other setting that we had to adjust was the CPU vCore was set to 1.35 Volts.
