Flashed BIOS = New OC Voltage?

[Tech Wizard]

Hello,

 

So I decided to flash/update the BIOS on my Asus X79-Deluxe motherboard today. I had a version from 2013, and got the latest one from 2016, promising "Improved system stability".

Everything went smooth. Decided to try and see if my overclocks from the previous BIOS version would work on the new BIOS, without changing any setting. All my previous overclocks/settings ran fine on the new BIOS version. Therefore, I decided to keep the same clocks/multipliers, but lowering voltage and see if that made any difference. I was happy to see that I could achieve same speed on lower voltage with the newer BIOS. I will attach a picture below:

 

 

All tests were done with Aida64/Prime95/IntelBurnTest (30 runs) for at least two hours. For your information, this was my first time flashing BIOS. Now, to my question:
What exactly did the flashed/updated BIOS version do? What changes did it made over the previous? How am I getting better results with overclocks (as in less voltage required to keep a certain multiplier)? Please do explain me, as I have no knowledge about what a flash actually does. 

 

Oh and also, which overclock would you run for 24/7 usage? I'm using an i7 4930K (6c/12t) + Hyper 212 EVO. Thanks in advance

It is possible to regulate voltage through software, perhaps they just re-wrote inefficient parts of the asm?

Every change in voltage was made inside BIOS screen. Also checked voltage on different software like CPU-Z to compare voltage between old & new BIOS, and every value was correct. Was that an answer to your question?

 

Edit: After flashing/updating BIOS, every setting was returned to default. I manually had to change them back to my overclocked settings.

Not really. I'm thinking ASUS just had more competent writers make an update.

yeah, sounds like they made the bios a little more efficient and improved stability

Yes, I can see that quality/stability is improved by myself. My question still stands unanswered

Sorry, can't tell you exactly how they reprogrammed things, that's way over my head. Basically it's like when a game dev releases a patch that improves game stability or a program dev releases an update on their software, except bios updates tend to be better tested and far more reliable. They literally just made the bios do what it does a little better (what does a bios do you ask https://en.wikipedia.org/wiki/BIOS ) as for a 24/7 OC 4.4 looks fine as long as temperatures aren't too high, intel says the thermal threshold is 66.8, but that doesn't sound right to me.....idk usually hear that 80ºC is generally accepted safe but 90ºC is technically fine and throttling hits at 100ºC. intel also says the 6600k is 64... so as long as you're comfortable with the temps it will probably be ok
