I’ve got the 5 slot (x8 electrical) x79 board and I’m looking for the BIOS that lets more than 2 cores activate.
I was sure I downloaded it from a blog, but I can’t find it again.
Need help to find that BIOS file, and or hone my Google-fu so I can find that blog.
Thanks (mods please move me appropriately as necessary if I am in the wrong place).

The best I can find is a missing GitHub links to pescew/x79btc-modified-bios
Which is not backed up on archive.org. If someone has even the filename I can search to see if I did download it. Probably around March 2023
I think it’s a complete fork. Here’s a saved page of Pescew’ repository.

Many thanks, I see now that it was ‘forked’ a few times. I was searching for zip, rar and bin files. It was a rom file 
.
Now to pay it forward I need to join all the forums I found with users asking how to get their CPU running more than 2 cores 
.
As a general purpose computer this isn’t terrible if you can find for $40-50. I found a 32GB stick of 1899mt/s LRDIMM for $6 to make up for the single memory channel. Only Sandy Bridge support as far as I can tell, now to try my E5 2670.
AliExpress has Walram MSATA 1TB on sale for $20.50.
I was planning to make a 9-16 output PC for a video wall, but I scored a Lenovo P520c motherboard for $45. Better choice, dual x16 slots and a x8. Skylake based LGA2066. W-2135 CPU was $25. Cascade Lake compatible BIOS, wow!
I only found the “low-power” 6 core to actually function. 2630v2. Makes sense with so few power stages.
