thanks man! appreciate it. I lost 1 board on my s17+ so before I pull the plug on a s19 wanted to shop around

I didn't want to start a new topic, but can someone link me to a valid legitimate pangolin miner website to look at a new miner purchase?

I agree, when too cold mine tend to be moody too, which makes no sense to me since heat is the enemy or so I thought. I think I could potentially get better results if I had the beefier PSU, I am running the 1600w one from bitmain on a dedicated 30amp 240v circuit, so I have plenty of power from the wall, but I think the PSU might be my limiting factor.

thanks for the clarification, so it would be a potential firmware modification or something. I was getting ready to order one since I'm not feeling the Antminer s15.

When you say they are talking about 44th etc, do you mean Pangolin is talking about putting out M10s with those outputs?

I missed the fine details of that post, the part about "each chip" individually. Wouldn't that be a pain to do and monitor? Other than finite control, what benefit would that offer? I'm not trying to be argumentative, I'm legitimately asking if there is a benefit to this, cause if there is I might be interested.

I could be mistaken, but doesn't Tazers mod (this forum) allow you to adjust frequency with no dev fee? I'm pretty sure Tazer is doing this simply because he is a cool dude (or chick?) and to stuff it in Bitmains face.

Thanks! I recently moved my miner off 2 separate PSUs (I at the time only had 120v plugs) over to a single APW++ and ran a dedicated 240volt line in my garage which acts as a heater for the pets  I used to be able to monitor draw based off of watching my solar monitoring GUI, but since the 240v is running directly off the main panel, and not the solar panel I'm not sure what the draw is. I know when I was running the 2 PSUs, I was easily maxing 1600w -/+ 200 with fluctuations and getting 14.7-15.3 TH/s mining rate with taserz BMMINER. I applied the latest LPM and plugged in Tazers BMMINER and I'm at 687MHz averaging high 14.x rate on an late model S9 that had the advertised rate of 13 something. I'm ok with the very small drop in hashing if I am actually getting 10% power savings. time will tell!

anyone do an "at-the-wall" number to see if this LPM whatnot is actually making any difference? I'm curious if the % claim they are making is accurate

just as an FYI, if you do a complete firmware upgrade to the new LPM, decide to go back and try to use the Taserz to go back, the S9 will tell you the firmware is incorrect. I had to go back to an older version of Bitmain firmware that I had downloaded a while back, then go back to Taserz. It seems that Bitmain is onto those of us that were overclocking :p

I just found another post here on the forums about cutting the blue wire... and it worked :p thanks for the earlier reply with the information though, if you hadn't told me I might have tried the splicing.

Good to know, however what I meant by "signal" wire was the control wire that sends the signal to tell the fan how fast to spin. I've done 2 different methods of software modifications but it seems they only last for a while and somehow they get overwritten. I just want these things on full blast all the time and some sort of good signal to go back to the PCB so it knows they are spinning and aren't broken

Ok, I'm going to go really old school simple hardware hack. The fans are a 4 wire PWM plug. one wire is (+) power, one is (-) ground, one wire is reading RPMs of the fan, and one controls the RPMs of the fans. I haven't grabbed a voltmeter yet to figure out which is which, but could we just jump the speed signal wire with the hot wire and make the fan run full speed all the time? Just a thought for those of us who are not worried about noise levels. I have found that even when I use this web browser mod, it still only sets one of the fans, and there is a discrepancy between speeds.

Fan thing worked! question, if I reboot the miner do I have to go back in and run the restart command for the bmminer?

"I'm also using the 88 version on an older 13.7 th model, just set it up, I'll let you know how it goes over the next week or so"

I am using 2 HP Server PSUs, 1x750w (running 1 board) and 1x1200w (running 2 boards and controller)
at 706.25 freq for some reason the single 750w PSU keeps resetting itself. I suspect it's because it might be going bad as I've been using it for almost 2 years.

Temperatures were varying from 78-85 -/+ 2 degrees in any direction.

It seems to run stable at 700 flat, running each board 4950ish-5100ish GH/S

I suspect I could get more if I could get the temperature in my garage lower, ambient air temp is around 78 degrees.

I think come winter time I can play around with it more, I will also try using my Bitmain PSU, though I dont get full potential out of it on 110v plug, I don't have a 220v in my garage.

Thanks for the info on the fan speed mod, I will give it a try!

Any Chance you could work in fan control adjustment? I'd like mine to be 100% all the time regardless of temperature

I'm also using the 88 version on an older 13.7 th model, just set it up, I'll let you know how it goes over the next week or so

So dropping the other firmware allows for overclocking and presumably underclocking, does it open up the Voltage and/or fan PWM speed% as well?

Hopefully this won't get removed since it is relevant to this thread topic, I'm wandering the various configs via WinSCP, and I'm wondering if we can just enter in the code in the bmminer.conf file somewhere in here to get the FAN PWM, and the Frequency...

"api-listen" : true,
"api-network" : true,
"api-groups" : "A:stats:pools:devs:summary:version",
"api-allow" : "A:0/0,W:*",
"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "100",
"bitmain-use-vil" : true,
"bitmain-freq" : "550",
"bitmain-voltage" : "0706",
"multi-version" : "1"
}

It likes the PWM 100 setting but even though I save it as 550 it doesn't change the frequency after the bootup. Any ideas?

ok, so it worked this time, thanks but it seems that even if I choose a different frequency it doesn't stick. Was worth a try though, thanks again!

Thanks for getting back to us! I was trying on Chrome, let me look at these last sets of pics and try again
