[Intel 12th gen non-K OC capable boards / bios versions]

Ah, right. It goes on the internal clock regulator of the CPU. I forgot about that. Thanks

I found Buildzoid's vid from a week ago on the ASUS TUF Gaming Z690-PLUS D4 (BIOS 0808).

It has a "Manual" option in the overclocking section, and unlocks BCLK OC.  Not sure what to make of that information. Would it allow for BCLK OC on D4?

Hi all, first post in 12 years ;o Been a lurker.

I'm mostly interested in B660 with DDR4, so I tried a few things:

Motherboards:

1/ ASUS ROG STRIX B660-A GAMING WIFI D4

2/ ASUS PRIME B660-PLUS D4

3/ ASUS PRIME B660M-K D4

4/ ASRock B660M-HDV (also D4)

 

Tried all available BIOS versions, dug around through settings, but none had BCLK overclocking. I didn't physically inspect them, as I didn't know where / what to look for back then.

So I have a direct contact at ASRock whom I asked and they checked with their mobo people in Taiwan: There are no D4 boards (ever?) supporting BCLK overclocking. The board needs an external clockgen (the latter we all already knew).

Buildzoid's most recent video suggests that there are/were/could be D4 boards that had the external clockgen/ - So I'm not sure if ASRock and Bullzoid are at odds there.
