High VRM temp makes OC unstable

mrthanhnguyen · Mar 8, 2020

The voltage with misleading you for. But how the vdroop does not make the temp lower? 1.28v in bios and at load vcore only 1.245 but temp is the same as I use 1.36v on the prime.

Software voltage readings can be inaccurate... so like I said you need to experiment.

Heat comes from the power loss of a cpu which is dissipated as heat, so you would have to compare the power the cpu draws at the prime and at the apex, not only the VCore.

The ripple effect is also a factor to take into consideration. You need less VCore at the apex to get stable under load compared to the prime as the vrm is more efficient at the apex. But the power the cpu draws is the same.

While that is true, living in this level of minutia for ambient overclocks is a waste of time. For all intents and purposes, all three boards listed will bring this CPU to the same overclock.... in other words, the seeming hard wall limits these CPUs have.

This. Don't buy into the marketing unless you are gunning for record scores. And when you do buy in, go all the way or its a waste of time anyway.

Whats up guys little bit late but that all right i guess.Here is my DIY VRM s cooling solution with X TRIO FANS.Smaller one an smaller rad and bigger one on bigger rad.They are cold as ice.

Ummm.... So you strapped fans to a vrm that doesn't need cooling........ Seems legit.

DIY is prety understandable word right?I know they don t need cooling,still temps are now way better

Definitely..... I had to do a couple double takes on your PC... Removing the shroud on the gpu as well and using 120mm fans to cool it is interesting to say the least..... Maybe you should go into WC it will look a lot better and the temps will be even lower since you seem to love the dyi stuff.

Are you Optimus Prime -- snacking on nuts and bolts, then washing them down with oil (the bottle)? Gratz on 5.3GHz.
