Oh man, I've just done some browsing about the Nehemiah and closed a window that explained how the Nehemiah multi could be unlocked (max multi was 12x).
I'll go look it up again...
Edit:1 search, 1st result, thank god, 🤣

Iirc it was the earlier ones that were unlocked. I'm in the middle of testing all my s370 boards and want to go and test the C3 CPU's I have laying around.
If I'm done, I'll report back here 😉
Nice!
I hope it turns out well. If you've got non ezra C3 chips, make sure to hold on to them too. I can't find any. Apparently no one wanted the C3 chips when they were out 😁.
I love the idea of a C3 for vintage gaming though for some reason. It's a unique set up.
As for the multiplier unlocks, I wonder if that goes in the other direction. Access to multipliers of 1x, 1.5x, and 2x would be ideal.
I'm done with the testing! 😁
And actually, of the 6 chips I own, none appear to be Ezra.
The chips are:
VIA Cyrix III 550 (5.5x100) 2.0v (Samuel?)
VIA C3 700 (7x100) 2.0v (Samuel?)
VIA C3 866 (Nehemiah?)
VIA C3 1000 (Probably Nehemiah)
VIA C3 1000 (Probably Nehemiah)
VIA C3 1200 (Can't be anything but a Nehemiah)
I tested using an ASUS CUSL2 with one of the newer BIOS versions (I think it was 1009?).
First I set everything to it's lowest (66Mhz "FSB" and 100Mhz Memory Bus (The 815 started having it's busses separated)), then tested with a known good P3 733 with a copper cooler without thermal paste (I'm low on paper towels ahem).
Then I tried the Cyrix III, but it gave no screen and then the "overheating" beepcode, no good.
Perhaps the board didn't support PPGA Celerons (which also require 2.0v), so I continued only with the lower voltage >866 chips as I'd rather not fry the board. Edit2: Reading the online manual it appears the CUSL2 supports PPGA Celerons just fine, so will try out the 700Mhz C3 when I continue testing again. Hopefully it's multiplier can be chanced
The other 4 chips posted alright, but were recognized as a Pentium II, 🤣
Alas, those 4 had their multi's locked, but according to the article I found earlier today they should be unlockable.
Another encouraging thing was that the 1.2Ghz part had, according to the BIOS, a 16x multi, even though it was running at it's normal 9x multi, and that kinda affirms the story written in that article.
I also got my power reader thingy and brought it to my attic, I'll test later how the C3's power consumption is 😉
Edit: I forgot to mention, even though the BIOS didn't recognize the C3's correctly, the board did supply the correct voltage!
