4790k stable @4.8 but are my BIOS settings OK!

I decided to leave the comforts of 4.6ghz and strive for 4.8ghz on air! Another change I made was to turn off the "Power Saving Options" and "Voltage Offset" (use a static voltage).

Is there anything that stands out that I could change in my BIOS to get even better temperatures/performance.

Temps are under 75c when stress testing and a game I play has never run so smooth, getting no stutter anymore which was driving me nuts.

Temps-buy a better cooler.
Performance-ramp up that voltage and multi. You still have some room in the temps,i would go 1.3v-ish and 4.9ghz.

No need for much testing in syntetic benchmarks,just use it every day and if its stable for a couple of weeks, its all good

I will give that a try (1.3v-ish and 4.9ghz) and are my other BIOS settings OK moving forward.

It seems fine to me.
Can you enable C states and retain stability? If yes, do it, you dont want your cpu to idle on 1.35v for example
Also, try to reduce loadline calibration a notch

Depends on your mobo as it seems a bit non standard. For example disabling Turbo on Haswell/DC per Intel specs will disable all OC as well because OC ratio is setting the turbo clock. But Gigabyte probably didn't read the specs and messed up their UEFI in that way where disabled Turbo in UEFI doesn't truly disable it.
I wouldn't use so many auto settings.

Without delid you may want to stop there. Cooling is pointless if you're already on a big cooler, you need a delid with LM to get anywhere.

No idea why you disabled all C states, sure you may not need the deepest ones but anything below C6 I would keep enabled.
LLC depends on your motherboard but in general the highest settings are overly aggressive and overshoot, you would have to measure or dig out someone's measurement/review of the board. Or check the reported voltages in HWiNFO if your board has good reporting chip.

Without knowing how much voltage each of the previous ratio steps took it's impossible to guess what voltage your next ratio may work at if at all. At these voltages it can be +0.1V for x1 extra ratio easily.

You really should test extensively with high load real workloads. The AVX and linpack burners are toasters and not that very useful other than testing cooling and how bad the Intel TIM is.

I followed the Gigabyte OC guide on overclock.net, it showed a few scenarios for setting up the "Turbo & C States" but not much of a explanation in regards to the different combinations:
https://www.overclock.net/forum/5-in...-oc-guide.html

Decided since I was only at 1.75V, with temps well under 75c that I could leave those settings off as per the guide.

I agree with you, I also feel that I should stop here. The chip is over 6 years old and I can still play games with a mix of Epic settings & over 100 fps, so not bad in 2020.
