6800k Overclocking Noob Issues

[SRLRacing]

I'm trying to overclock a PC I just bought that's going to be a gift for someone in my family and am having trouble getting a stable overclock via the bios on a 6800k. When I OC via the automated tool within Windows its more or less stable at 4.3GHz and a core voltage of 1.25 with a .1 offset but inconsistent in how it applies the multiplier and much rather have it implemented at the bios level to avoid this. The motherboard is an ASRock X99E-ITX/ac and I'm using the A-Tuning for the automated OC. However, when I try to manually do the OC in the bios and utilize the same settings listed in A-Tuning I come up with an unstable OC and cannot even get a stable 100MHz OC via bios. What am I missing? Any guidance on this would be much appreciated.

what do you mean by "inconsistent in how it applies the Multiplier"?

What temps and what cooler?

Peek temps are in the low to mid 70's but mostly stay in the mid to high 60's. The cooler is a 140mm NZXT Kraken X41.

When I look up what clock speed its running through Aida 64 or A-Tune sometimes it shows a speed of 3.4GHz with a multiplier of 34 and sometimes a speed of 4.3GHz with a multiplier of 43 all while it should be in a state with the multiplier at 43. I ran an encoding test using handbrake and only saw 3.4 GHz while encoding and both programs showed the multiplier being at 34 during this time.

Change the ratio to Fixed instead of dynamic to see if that fixes the problem and if it's unstable/refusing to post try to put more voltage in (You might have to set the voltage mode to override instead of offset because of the fixed ratio). Also try setting the voltage going into the package to about 2v that might help with stability.

When I try to OC via the bios I set it to fixed and I have tried voltages all the way up to 1.375v and had the Input Voltage set to 1.9 (I'll give 2.0 a try). That was an unstable OC. It boots but when I run a stress test through Aida 64 it usually fails pretty quickly. The A-Tune OC doesn't give me many options except for if the voltage is adaptive or fixed and what the clocks and voltages are but other than the weird thing with the multiplier it does pass a 12 hour stress test on Aida 64. I do however get a strange freeze somewhere around 30 seconds into the stress test that lasts about 30 seconds to a minute but the rest of the test goes smoothly.

Well, to hit 4.3 with my 6800k I needed 1.425V so you can try that (as long as you can manage the heat and keep it under 80C). I'm using about 1.45V for my 4.4 right now (it maxes out about 75C with full load). But if you can't hit 4.3 @ 1.425V then you might as well dial back to 4.2 as the heat output is not worth the small gains of 100mhz. (tbh I should dial my cpu back because it runs pretty hot) Once you get the core clock stable you can start to tinker with the ram and ring. But that could mess with your overclocks so I would be careful adjusting those.
