^This, I highly doubt you'll be able to hit 4.3ghz with anything less than 1.5v. You may even need up to 1.55v to get there.

Don't set it to 1.55v right off the start. I'm just saying that it's possible that you might need that much voltage for a 4.3ghz overclock. Because you're not stable at 1.48v you should start off at 1.5v and if it's not stable then go up in small increments from there.

You might also need to increase your CPU-NB voltage to 1.35v-1.4v to get it stable at 3000mhz. Your CPU-NB is most likely unstable at your current voltage of 1.3v.

No bump your cpu-nb up to 1.35 volts and see if that fixes it.

Im at 1.38v cpu-nb

1.54v and at full load it hit about 1.6v on 100% llc still no catch...

I saw 1 guy got his 1090t at 1.66v on 4.5ghz..with llc 100%

So dont know why im still getting core 5 unstable..but 4.0ghz its all good so my cpu is not dead or anything..its just getting that fatal error..maybe ill bump the voltage a lottle bit more??
