ML for i7 8700k overclocking?

[lelxd]

So i understand that there has to be a specific amount of coolant in a loop to keep temps of overclocking low, but how much would i need exactly to get the i7 8700k to 4.7Ghz at a low voltage

4.7 is an easy job for 8700K, but every chip is different. try following guides and find the lowest voltage possible with stress tests

Does stress testing refer to only temperature? Im kinda new to overclocking, but ive been doing my research.

Hi lelxd,

There are different type of stress test :
- Thermal stress test like OCCT which use "abnomaly" your CPU to make him a heater.
- Non avx stress test (Prime95) that test your CPU without AVX instruction.
- AVX stress test (OCCT, Prime95) which test your CPU for the AVX instruction
- Mixed stress test (RealBench) that uses AVX and non AVX instructions.

AVX is used for scientific calculus, few games and video editing.
This instruction lead to a full usage of the processor which induce a higher voltage needed to sustain stability.
That's why you can see a lot of overclockers putting an AVX offset, to reduce the frequency when AVX instruction is detected.
