The worlds current number 2 extreme overclocker and all-around outspoken guy Xtreme Addict has created a brand new guide for those specifically for overclocking Samsungs B die memory on the ASUS Z170 Maximus VIII range of motherboards.
“BIN MOTHERBOARD! I binned overall 10x M8E and with Uncle Mad around 15x M8I. Board matters, believe me even though IMC is inside CPU. IT WAS SAME WITH MANY VENDORS AND MANY GENERATIONS. JUST ESPECIALLY NOW IT’S MORE VISIBLE AND CLEAR THAT WE HAVE TO BIN BOARDS. It’s not possible to get exactly same motherboard PCB, each PCB differs inside, copper layers which produce signals and so on. Those are very small and subtle differences, but influence OC potential a lot.”
“Note that mostly after LN2 benching, many motherboards degrade. Sadly but small sockets (BGA balls and traces under the socket) are very sensitive for full pot, especially fast temperature changes. That’s why in Asus Shamino’s/Elmor’s Z170 guide we can find tips to slowly cool down CPU in order to preserve socket. Some motherboards are “RAMBO” edition, some sadly will degrade. For degraded boards you can try to clean socket + DIMMs with aceton and dry motherboard for a very long time.”
