    wow 1.9v VRIN input voltage for 4Ghz overclock?

    That’s not all, actually. As soon as you change your CPU frequency multiplier on an ASRock mainboard, the CPU input voltage will be increased from 1.8 to 1.9 volts
    amateurs you only need keep VRIN within 0.5v of vcore meaning 1.9v VRIN would equal vcore of 1.4v or there about's, way too much VRIN for mere 4GHz overclock maybe at 4.5GHz but no way at 4GHz

      Most of it fine, just the VRIN is little bit overkill for mere 4GHz overclock, would be fine leaving it @ 1.8v as this allows stability to 1.3v vcore which you won't be using on 4GHz overclock


      they even admit so on page 4

      There is one more thing you should be aware of. The voltage on the CPU cores is usually the only voltage that affects stability of an LGA1150 platform. However, when it is set very high, you may find it necessary to increase the CPU input voltage as well. At its default level of 1.8 volts it is enough to let you increase your CPU voltage to 1.3-1.35 volts. You will only need to adjust the CPU input voltage if you’ve got a special CPU cooler. With ordinary cooling solutions and non-modified CPUs, it is better to remain within 1.2 volts.

        Dagnabbit if HW-E is like this I'll have to relearn flipping voltage acronyms and such.

          probably will be heard Intel stuck VRM's inside cpu just like haswell 1150

            yep haswell has been and we all should learn something new everyday.

            i only need to have vrin 0.4v above vcore me.

            any less and i have stability issues and i aint found giving it any more helps with the clocks any.

            4ghz you can leave the volts all stock and just up the turbo, i could do this to 4.2ghz and it was only after that i need to do anything else.

              yeah 0.4 to 0.5v VRIN is sweet spot

              marsey what's your memory read speeds?

                i am on a newwer version, aida 4.0 and the benchdll is 4.1.59.

                but i get 35/37/35 plus change at 2400 cas 10.

                running 2200 cas 9 as my day to day as i can do so on much less volts.

                  I used 1.8 VRIN for a 5GHz OC. They're way off. Haha.

                  General rule of thumb is 0.5 volts above vCore although I haven't experimented going lower than 1.7 volts at stock ish speeds as that's 1.1vCore so it should in theory be 1.5 - 1.6 VRIN.
