I live a couple of hours away and would love to come and take a tour and possibly drop off a couple S17's for hashboard repairs. The website asicmaster.com won't come up and I'm confused as to whether it's the same as Crypto Miner CHR or what's up with the split or how that went down. The phone number is the same but sites/names are different, so I am contacting you here to try and get info on how to get repairs from you guys. I sent you a PM but I don't think it went through so I'll try again here. I am trying to find an asic repair shop. Trying to find a place I can drive to, as delivery always gets damaged. A personal tour would go a long way toward establishing trust, as does quality repairs and quick turn around. Thanks, and thanks to all the posts, at least I have a couple of places I can try; but I'm reaching out to you first and we'll see what happens. Shoot me an e-mail peterjdorf1973@yahoo.com

Thank You. I was looking to underclock/undervolt improve efficiency but keep hashrate. I get a pretty good and stable rate now at 59T-62T average with 2331w from the wall, about 39w per TH (not great, not bad). Currently my "factory" settings on these used S17 Pro's are set at 19V and 550M that shows a frequency at 632 on the status page. But as you said, to maximize efficiency I should lower both volts and frequency to the lowest setting and then slowly step up the frequency until I start to lose stability.

I understand about the auto-tuning per chip rather than per board and I will try custom firmware at a later time to do any underclocking/overclocking, once I get my ROI from these units. Until then, I think I'll just let them run for a few months without any changes(they run fine for now, ain't broke don't fix) and then I'll follow your advice and get the custom firmware once I get my money back. Thanks again.

Can you point out some good reading about the do's and don't s of setting your frequency and voltage to maximize performance and efficiency. Great discussion on how to set your frequency and voltage (Topic: Antminer S17 pro fixed Frequency and Voltage default firmware). But I haven't been able to find anything about which settings to use and why. I don't want to fry my unit so I'd like to get some info about setting fixed frequency and voltage on the S17 pro. Just looking to find the best frequency and voltage to maximize $$$$ and lower power consumption. Overclocking info I've found is vague and not very specific to Asic's.

Thanks to philipma1957 and mikeywith for the great info I've gotten so far from a few discussions I've read: fan speeds, chip temps, etc. And now frequency and voltage. New to the mining game but learning quick because of you guys
