Title: Will I brick a fixed frequency card by loading autofreq firmware? Post by: ccgllc on March 01, 2018, 08:30:34 PM I have a couple of older fixed frequency S9s in my farm, including on 14TH one that is running at 13.6.
I'm just wondering what would happen I loaded one of the auto-freq firmwares? My guess is that it would boot (controllers likely being compatible), but not find the cards? Just thought I'd get some opinions before jumping... Title: Re: Will I brick a fixed frequency card by loading autofreq firmware?

Just thought I'd get some opinions before jumping... can you pick any freq? are those the older ones with many freq to pick from? they allow for a fairly quiet s-9 if you run at freq 500 and drop fans to 60% you should consider selling them as people that home mine and have sound issues like them. As to flashing them you better make sure you pick the correct firmware or you will brick the controller. Title: Re: Will I brick a fixed frequency card by loading autofreq firmware?

I dont have personal experience with it but I would err on the side of caution.

I dont have personal experience with it but I would err on the side of caution. What I had noted when I recently replaced a controller was that it come with 400 Mhz fixed frequency which worked, albeit slowly, with my auto-frequency boards. Flashing it up with an auto-freq firmware restored normal speeds. Just not sure an older controller could handle the newer firmer. MUCH less sure what the fixed frequency boards would think - although that is low risk. If it failed, so long as the controller wasn't toasted, I could just reflash the fixed firmware. Really just screwing around exploring these things. Title: Re: Will I brick a fixed frequency card by loading autofreq firmware? Post by: HoleShot on March 04, 2018, 04:39:59 AM New controllers with the latest firmware do handle both fixed frequency and variable frequency boards, even mixed on the same controller. The fixed boards will just use whatever you set as the initial frequency and the variable boards will go through the adjustment scan process.
