When I remove the PSU to swap it for the replacement one Phil is sending me, I'll make sure to dismantle further than that and provide pics of everything I can.

That McAfee pin is hilarious!

So Phil is going out on a limb and is sending me his replacement PSU to determine whether or not my PSU is damaged. This is a very generous gesture from him and ill do whatever is necessary to make sure he is made whole when this is settled.

I'm quite convinced its the PSU given the events that precipitated the reduction of hash rate, namely the pop, flash of sparks, and puff of smoke from the PSU. Combined with the stated specs for the PSU (below), I'm struggling to believe that the input voltage difference between 208V and 220V is what is hamstring the hash rate. I will add that the autotune function is not raising the avg board freq to what it was prior the PSU incident. Current board freq: 445-499-434 resulting in 28.5TH/s. I can only hope the boards were not damaged.

Model:
P10-12.5-2250-V1
Input:
176-264VAC 50/60Hz 25A Max
Output:
12.5V 180A
12V 10A

Was it not possible they updated their pricing in a subsequent post without updating the original? Was there something wrong with asking?

It was provided directly from Pangolin support.

Update on my M10:

Unfortunately, it would appear I am at an impasse with Pangolin support after hours of communication on telegram. They are denying anything is wrong with the PSU on my M10 (despite not asking me to send them pics or remove it) and are now claiming two things:

1.) The input voltage of 208V is low and that 220V is ideal.

2.) The hash rate is within normal variance as relayed by their engineers of +/- 5%, despite being 8.1% off of spec at 28.5TH/s.

At a loss of where to go from here.

As far as disabling fan check, you may want to check out BraiinsOS over in the mining software sub. Open-source, free fw for the T1 and S9 from the team behind slush pool. I know the S9 version has the ability to disable fan check.

Are you saying your price for an S15 shipped is now $750?

Quick update: Telegram support recommended trying downgrading to January FW to see if that would fix the low hashrate problem that appeared after the PSU problem. As my M10 is not run at home I had to wait to come in this morning to give the downgrade a try and, unfortunately, it has not helped. No change in hashrate, still only ~28.5 TH/s.

Will get back in contact with support over telegram tonight to see about next steps.

If Bitmain follows the Z11, then that means they've gone back to not using built-in PSU's (which I would love).

I can only hope! Hopefully that what they want me to do as part of troubleshooting.

Unfortunately, I still cannot get this M10 to hash at 31TH/s. Last night I was seeing 31.1TH/s, now its hovering at 28.8TH/s.

Freq:
451-505-442

105 eff. chips per chain.

I am in Fairfax County, VA. I sent a message to the pango official group telegram as well as Yang JYan.

I have created a support ticket and will update going forward with how Pango resolves this issue.

From what I recall, the pop originated from the PSU and was loud enough to make me jump back. The PDU's are still being used right now without issue.

Edit: After giving it about 4 hours now, I just plugged it back in and everything is working... Very suspicious and will be sitting within view of this guy for the rest of the day with my fire extinguisher close by. Will still go through the support process with Pango to see what they have to say about what may have happened.

So bad news, after I set up my M10 and let it run for 45 minutes last night I came back in this morning and the breaker on its PDU was tripped. I swapped it to a different PDU and upon plugging it in, there was a very loud pop with sparks and a small amount of smoke coming out of the front of the PSU.

I've had a 0% failure rate over the years, so I guess this is probability biting me in the ass. Will update with next steps.

My first arrived today. Running quiet (was worried by how heinously loud it was at start up) so far and mining at 31.1 TH/s. admin/admin for login. No page to change these details, nor can I find any method by which I would update FW. Does anyone know how? I tried downloading the manual but its in chinese...



Edit: also, my FW version is 20190301.16.1

Pretty cool they’re only moving up to 12nm. Now I just kinda wish i’d held off on my order!

Got my text from DHL even though this is my first international (I think) shipment by them. Pango must be putting our phone numbers with the orders. Estimate is Monday for me!

Edit: Pango just updated my order status with tracking info as well.

Found the user and one of the posts I was referencing above ^.

I think the guy who had a couple PSU's die said it was a week turnaround from China.

I'm #13345 haha. Still processing for me.

Looks like I got in just at the end of the "ship out in 7 days" batch!
