Hi ive got a ryzen 5 2600 and been testing overclocks and seen that they easily overclock to 4.1-4.2 with decent cooling, I have mine cooling with a kraken x62 and cant get it stable past 3.95ghz and I have to give it a lot of voltage which in turn creates too much heat im on a aorus x470 gaming ultra not the best board I know, but it was the same on my old b350 board. also ram is just set to xmp profile of 2666mhz have just lost the silicon lottery and got a dud chip? also I only game and web browse so overclocking I wont see much benefit? also this board doesn't have precision boost over drive im on latest bios.Thanks
