I have to stick with at least 8 cores 16 threads, because I plan to use it as Multiseat-PC. 4 x Monitor, Keyboard, Mouse. The Blink refers to RGB. Not necessarily colorful disco lights. I got a Deepcool Matrexx 30. My glas panel case.
I did only once overclock an old AMD Athlon II 3X, by increasing the base clock speed. After I faced blue screen once in a while I increased the voltage. Then it happened rarely, so I gave it a tick more core voltage. Then it stood stable.
