... I'd assume, if this was true, we'd be able to easily find, for this specific reason people would have kept rehosting those BIOS and we'd find them floating around (I looked for 1.01 and 1.13, nothing)

I agree, and know what you mean, especially true with ES or early launch/review samples too, however.... what I said remains true as well.
What can you see at OC Tweaker >> CPU Config> Can you see Blck Freq, Bclk Step, Bclk step delay (These are the "granularity" type settings mentioned by the Mod at MSI Forum I linked, answering why external clock gen remains)

Sky/kaby had non-K, and people knew this, all those BIOS are still around too if needed. Everyone always tries
There is always a way back, and as I mentioned, even if this review guy is the only one in the world that got that early BIOS, he would have shared it and or provided screenshots/CPU-z validations etc, and that BIOS would be around.
I agree, maybe many do not dump, but I'm sure as soon as he posted that review people wanted that BIOS and even though he didn't reply on that guide I'm sure people in background, other forums, etc ask him for it and he shared around, so it should be out there and I only find his one reference without any validation or proof
It may be true, but I'm not seeing that anywhere with Z370

Can you find other reviews of Z370 with high Blck? How about CPU-z validations?

I found this Reddit Thread referencing the original Level1Techs Thread: https://old.reddit.com/r/intel/comments/...king_to_52_ghz/
I just paid attention than the guy from Level1Techs said that he was "simulating" a Ci5 8400, as it seems that he was actually using a Ci7 8700K at lower clocks. Basically, that is no proof that non-K Coffee Lake overclocking was ever possible for obvious reasons, and there doesn't seem to be any other source saying that (Ironically, most things I found point to that Level1Techs Thread). I mean, giving the commotion than non-K BCLK overclocking produced during Skylake, it makes no sense that Intel would do the same mistake twice in a row.

@zir_blazer I linked that above too

Yes, good eye, thanks, I meant to use Z370 So.... yes, I was looking at the AMD replies due to X370 Funny to see same issue there with AMD Too, I guess they both just need to bring back FSB and be done with it

I unfortunately have bad news.

In the forum link posted, the 8400 was in fact just being simulated by disabling cores on an 8700K. Intel ME blocks anything above 102.7MHz BCLK on non-K SKUs, so even if we did have this BIOS, we won't be able to BCLK OC any locked chips.

I wonder if disabling ME would help, but at this point, someone should have worked that out by now.

Edit: Oh, didn't see that someone had already found that out. But yes, the TL;DR is that non-K Coffee Lake is hard limited to 102.7MHz BCLK.

Indeed bad news!
However, thanks guys for the effort, that you put into finding the details.
I guess the hope is over now, then. :-(

ME FW Pro should be able to find the byte we need to edit, but I guess maybe it's harder than it sounds since no one has found yet

I know it's been months, bumping this up just to see if anyone had made progress with ME FW pro?

Why is the limit for some 102.7 and others hit 103?
Is it definately a limit in the ME or is it via microcode?

Would like to narrow it down.
