The 1700 is back from the dead

So I'd like to share a story about a Ryzen 7 1700. One that I wrote a eulogy for because it refused to boot.

I have a new motherboard, some new BIOSes. Tried booting it recently on stock. It booted! So the good news of this is whatever "killed" it wasn't the CPU itself. Swapped out 1700s and now this is the one in the mITX build. If it stays alive the other 1700 will go to a good cause. (AMD replaced the 1700 when we all thought it was dead.)

I've also recently learned something about Ryzen Master - the settings are not applied to BIOS. I originally did all of the testing in BIOS because we review in Linux. There may be a flaw to this methodology or it's just highlighting my inexperience with overclocking - because at the moment I have this "dead" 1700 running through Ryzen master at 3.7 on all cores at 1.2V. This same one refused to do ANYTHING if I moved away from stock settings in BIOS. Now I know why - it's probably throwing way too much voltage at it, more than the CPU can handle.

So I'm going to keep testing in Ryzen Master and see how high I can go without blowing it up. Once we're there we'll try duplicating it in BIOS. If this all works, there may be an article from this!

Update: Think it took a bump of 1.25 to get 3.8 stable. Will keep it here for a bit but so far so good.

Started Prime95 testing and it's locking up even at 1.3V. Higher the voltage, longer it stays in the test though.

1.35V @ 3.8 seems to work. Temps climb and then dramatically slow in the mid-80s as the test stays.
So I think this is as good as I'm going to get in this form factor and case.
Next step: Try and get this replicated in BIOS.
