Discussion around CPU VCORE versus VID voltage issues

"I was under the impression if i had it set to manual it would not exceed the voltage i specified and would bluescreen if the cpu wasn't getting the amount of voltage it needed, in which case that was a sign to up the voltage. And if i had it set to variable thats when it could adjust the voltage on its own slightly." This is the way traditional BIOS's usually work, but the Asus UEFI BIOS is quite a bit more advanced than that.
You are not setting a base voltage. It can go above or below if it deems it necessary. What you're doing is telling it where you want the voltage to be, but it will adjust voltage as needed. In some cases, even completely ignoring your target voltage. This is why the world record for CPU overclocking was set on an Asus board. They're such advanced motherboards that they can even make changes to core clock while the machine is running. Keep in mind that the world record was set on an FX-8350 cooled via direct contact with liquid hydrogen on an Asus board that had a modded BIOS installed. Don't expect to break world records without putting forth serious work. But that's enough side stories, let's get back on topic.
Should your next step be to lower the CPU voltage? If your temps are under 80C at load while overclocked, there's no need to lower the voltage.
thankyou you've been a big help with understanding things, and that bit about asus boards being able to adjust voltage explains everything. so theirs basically no reason for me to go to variable voltage then. Welp, to bios i go for a 48 multiplier.
Weberdarren97 shared insights on how traditional BIOS settings typically function, noting that Asus UEFI BIOS offers more flexibility than standard systems. He explained that manual settings prevent exceeding voltage limits and avoid blue screens due to insufficient power, while variable settings allow automatic adjustments. He referenced a world record overclock achieved on an Asus board with liquid hydrogen cooling and a modified BIOS, emphasizing that such feats demand significant effort. He also mentioned that variable voltage can be useful for replacing components like MOSFETs but requires advanced technical skills.

He mentioned that setting a base voltage isn't necessary, as the system can adapt accordingly. The discussion highlighted the importance of understanding motherboard capabilities before attempting overclocking.
I've modified a MOSFET on my old Asus M5A99FX PRO R2.0 board and achieved 7700MHz on the FX 8350. The main hurdle was thermal management. I originally had eight 120mm fans on radiators to keep the CPU cool. The heat spreader material used in production isn't as effective as some alternatives, but I didn't want to replace the 8350 just for higher speeds. Plus, I was already drawing 1.2KW from the wall. A video of the delidding process is available. This isn't my video—I'm not Linus.

Damn that's crazy. I've seen others using a vice for the process.
