Important question difference board

[yg604974]

What is the difference between overvolting jumper and ln2 mode jumper? Some asus motherboard supports voltage jumper
But some do ln2 jumper, but never both. Would nitrogen cooling also work on board without ln2 mode like asus x99 e ws, which
Only has overvoltage jumper? Would nitrogen cooling work on boards without any jumpers at all.
This is a scientific question and I need to know the main difference between overvolting jumper and ln2 jumper.
Which is better overall. Ln2 mode>ov mode or ov mode >ln2 mode?

You want a motherboard with the ln2 jumper if you plan on using liquid nitrogen for maximum overclocking. Nitrogen can be used on any motherboard, but the purpose of the jumper is to ensure the motherboard will power on at very low temperatures. Overvolting won't help with startup at extremely cold temperatures, but it allows for more overclocking (and possible CPU damage) if you have a good enough cooling solution. ln2 cooling is for extreme overclock contests only.

So this proves that boards with ov jumper are maybe pretty useless. Either buy one with ln2 mode. Thanks for your help

Motherboards with an ov jumper are useful to achieve a higher overclock even if there's a risk of damaging the CPU, but nothing comes close to liquid nitrogen to cool a system (it cools the CPU and the surrounding components). Few buyers will ever invest in liquid nitrogen just to win an overclocking contest; you probably don't want to use one in your home.

 

[questioncpu]

yes but when you look on hwbot benchs you will see that on ln2 mode the vcore is also very high. so for me it sounds like ln2 mode can integrate voltage stability maybe not much as ov jumper but it will also be good for high voltag i suppose.

 

[questioncpu]

by the way questioncpu is yg604974.

Correct, but isn't an issue with ln2 since the CPU and the VRM stay so cold that they shouldn't overheat even at very high overclocks. The ln2 jumper basically does what the ov jumper does (allowing for higher voltages), but it also does a lot more to ensure the system will POST when it's very cold. Several components are not identical and ln2 compatible motherboards usually are more expensive. If you want to play with ln2, then you should read this http://www.tomshardware.com/reviews/kaby-lake-de-lidding-overclocking-test,4970.html and other similar articles. While liquid nitrogen cooling is interesting, it's utilization is limited to achieving top benchmark scores.
