[lee group]1150$! The group buy of hosted bitmain S7 @4.73T online on 27th Jan!!

[takagari]

Honestly guy's I bought one from Cryptominer.ca and never regretted hosting with him.

I know this thread just screams issues. Glad I switched.

I've been overall pretty satisfied with my uptime on the miners.  I do wish the hosting price could come down some, but that was known coming in.  Yeah it does take some time to get a response but it is normally resonable.  I haven't experienced selling my hosted miners yet so in the next few months I will be interested in how that process works and what value S7's are going for in the China market.

Last year was fine with S5, this year has been sketchy with downtime and under hashing S7

Plus the website is non existent to monitor the miners

Sold all S7 back

I'm satisfied too, but also expecting lowering the maintenance prices. Right now, Bitmain's Hashnest maintenance is roughly 20% lower than Li's maintenance fee. With new generation of ASIC coming 20% could be the decision is it or not profitable.

Has anyone received last months down time? I had 48 hrs and see the miners are off again now as well since 6 hours.

Is there a better way to submit downtime than on the sheet we make our fee payments on? I don't feel the need to overload him with emails but if that's what it takes in the end I guess it's what I would do.

Definitely email!

Here is the form for reporting down miners:
https://docs.google.com/forms/d/1Jn_wKd0phVlJtqDO9th0R2lkxNxkyQ0radDGcWf7STk/viewform

But e-mail and btctalk private message in parallel will make no harm.

Sorry for the long time miss from forum, my astrill canot work properly.
Currently, i face two main issue with new s7 miner
1: some s7 canot perform as stable as  advertised.
     Our engineer still try to find the reason why some s7 is under performance, the problem may caused by the psu we use,
     we will  order some bitmain's psu to check whether we can resolve this issue.
2: we donot send the downtime compensation for the last month.
     we will send the compensation to all old s7(4.66T) owner according to 18 hours downtime for last month.
      The compensation will be 0.004*18/24*4.66=0.014 btc  for each old s7.


I am still waiting for above compensation which you still did not send


Following email send by you  to me on 23rd of Feb

Kano pool is paying out according pplns, it is possible that they pay out more than 100%pps, but it is also possible that they pay out less than 100% pps if they got bad luck. so i think 100% pps is still fair for a long run of 20+days
as for downtime, i will arrange the 30-12=18 hours downtime compensation.


All emails forward to you.

After sending all emails and proof of downtime no reply from Lee

3 miners down for 36 hours, still counting...

[superbull]

miners back online finally, 39.6 hours x 3 units = total 118.5 total downtime.

also i noticed that Li has recently changed his internet access from China Telecom x.x.x.70 to China Unicom x.x.x.223, my pool stats is showing a lot reject and miner fallback in the past 3 hours, ping test from my proxy to Unicom ip got almost 10% packet drop with 120ms turnaround avg ,anyway 120ms is OK but severe packet drop must degrade hashing performance, not sure if anyone seeing the same

Same here. Still waiting and hoping all of his time away is either searching for ways to lower power cost or a psu solution for low hashrates. Still seems like my 4.66 TH/s S7 is underperforming when I check it on F2Pool well under 4 TH/s most of the time.

[superbull]

what the hell power transformer problem again and again? all S7 down since 0715 Beijing time today, 4.66 and 4.73.
as usual bw.com hashrates dropped from 81.63P to 68P at same time.

[mxnsch]

Confirmed, all my miners also down.

[pcfli]
