Hello everybody,
i am quite new to the OC thematic and want to be sure to run stable, not too hot (specialy in summer) and good lifetime for Mobo and CPU of course.

My data:

Mobo Asus P8P67 Deluxe Rev 3.1 (latest Bios)
CPU i7 3770K
Cooling Noctua Nh-d14
Cooler Master Silent Pro RS-500-AMBA-D3 500 Watt 80+
Graka Nvidia GeForce GTX 1070 Ti (Core 1607 Mhz/Memory 4006 Mhz/GDDR5)
Samsung SSD 860 Pro
RAMS [RipjawsX] F3-2133C9D-16GXH
Default from Vendor settings i put
DDR3-2133 (PC3-17000)
16GB (8GBx2)
1.60 Volt

In first step i put optimized defaults in BIOS and as i use Virtual machines i enabled this too.

With this default i have a Core Speed of 3911 Mhz / 3,9 Ghz

Cinebench 1038 Ranking

Is there a default setting i should try to start? (Bios Konfig)
Important for me is that CPU and SSD doesn`t get life shorter or killed and of course Mobo gentle

Thanks for help

A good 3770K can do 4.5 GHz at about 1.35 Volts. You already have a good cooler and the VID on your CPU-Z screenshot is quite good as well (1.152 V). Raise the CPU clock slowly by 100 MHz, test it with latest Prime95 version and continue doing so until the system gets unstable. Raise the CPU voltage as well now, I recommend 0.05 voltage steps.

There is obviously much more to CPU overclocking, so read a guide carefully before adding to much volts. I would recommend to stay below 1.4 V for Ivy Bridge.

Here is our guide, it goes into detail about Loadline Calibration (you should set this right as well) and gives a step by step intro of how to overclock your CPU: https://www.overclockers.at/article...rclocking-guide (Google Translate will help)

Your PSU should work fine, 500 Watts is enough for an overclocked 3770K + 1070 Ti.

The lifetime of your CPU will not be shortened by a moderate overclock (4.5 with 1.35 Volts). Although the silicon can degrade and your CPU might get hotter and/or need more voltage to hold your overclock frequency. So even if the system is very stable for some years, it could become unstable after a while and might need further adjustment. I recommend lowering the CPU frequency if that happens to avoid additional heat.
