Some of the S7 we had available were built at factory with only (1) fan. If the unit is working at expected temps then your S7 is one of them.

I ordered one of these from you and I was nervous after sending my bitcoin, because you sent a confirmation of the order, but never sent me a confirmation that the device was actually shipped. Then a few days later it showed up at my door. The product worked as advertised.
So I just ordered four more of these and the transaction was confirmed with coinpayments. But I still don’t have an email from you guys even confirming the order.
Good company, but you all need work on the communication. I know you’re swamped but sheesh hire another guy! Seriously though, thanks for selling a great product at a fair price.

Capitalgains (verified owner) – :
The unit was shipped very fast and has been working great. The only thing I recommend is sending out updates on when the products are shipped. I had to contact the company to receive the tracking number. Other than that, I’m very impressed. Thanks!

Joseph G,
Will there be S7’s listed tonight or tomorrow a you mentioned? Thanks
Joseph g – :
We are still catching up on orders from last batch. We ran out of the 120mm fan we use on the S7. Currently sold out and expect to be in stock Monday. It will be a couple more days before we relist.
crazyclover – :
Any ideas when these are back in stock?
jakeasmith99 – :
Can you only pay in bitcoin or can you use a card?
jakeasmith99 – :
Thanks for informing us ahead of time to have money in our Coinbase account.. that really screwed me over. Usually you can purchase items on your website on a card.
Joseph g – :
Sorry about this, really not our intention. When it come to miners them self we only accept Crypto payment and all sale are final.
kryptokupp (verified owner) – :
Joseph G,
Thank you for the fast shipment and quality used S7’s received. I am very pleased with your service. Do you have any idea when the next batch of antminers will be available?
Thanks
Joseph g – :
We are working on more and should have another batch in about 10 days
KingSwizy (verified owner) – :
Miners are absolutely fantastic. Ordered two S7’s and both came in amazing condition. Very clean and pristine. Will definitely buy more from here when they come in stock. BTW voskcoin sent me
dgwayne1 (verified owner) – :
This is solely my experience with the two miners they sent me. This is not a reflection of their company because so far the tech support has been very helpful. Ok here goes…
I bought 2 of these miners. From the moment I turned them on I had issues. The hashrate was all over the place. I Changed pools and it seemed to be cleared up for about 2 hours then the hashboards were dropping out left and right. I pulled the comm cables and swapped them around with no success. I cant run them over 4.1 TH/s at all. Most times 1 board will die every 15 minutes and the other one has had all 3 boards die. they are VERY unstable regardless of my actions. At this point im at wits end because for me $1700 is a lot of money to have products that don’t work. The support team is currently working with me on a solution but as you know that cant come quick enough. The game of crypto is a tricky one and the sooner you can get hashing the better. So downtime is a BIG deal. Im sure they test all the products before they ship but I guess my two miners got overlooked somehow because they are quite frankly lemons. I hope to reach a resolution with these guys as they have been very helpful so far BUT this shouldn’t have happened to begin with.
Joseph g – :
If you have not do so already. Contact us via our contact page for an RMA replacement. We will send you a prepaid label
KingSwizy (verified owner) – :
Hey can i receive some help? After a while one s7 started to have issues. One or two of the boards drop down to 16c and the miner hashes between 1.5-2 TH. Any advice? Hope for a response soon. Thanks!
Joseph g – :
Contact us via our contact page. please provide your phone number and a good time to call you. Albert will follow up with you
KingSwizy (verified owner) – :
I still have not been contacted. It has been three days I haven’t received any type of contact about my S7.
coltburdine (verified owner) – :
mine dont die they work but with factory frequency they dont go over 4.1/4.2 th/s what is optimal frequency they should be set at or is this something we shouldnt mess with?
Joseph g – :
Couple possibilities. 1) Power supply should be able to push 1500watt “Don’t starve the unit” 2) Try different frequency. The default is 700 but you might get higher hash rate at 680 or 650. Sometime the Hardware error are to high, you can see this under HW count. Play with the frequency and check the error count. Finally update the firmware to the latest. Keep us posted
dabomb6608 (verified owner) – :
Received one(of four) with faulty hash board (all X’s on status page). Have checked connnections and everything else without opening up. Should I just submit the RMA and send it back? Order # 14287, I have emailed both Missa and you (Joseph) with no response in 3 days.
Missa – :
Based on your e-mail the technical assistance you needed was beyond my knowledge so I had forwarded the e-mail to our senior tech support guy. I was unaware that he hadn’t replied to you, so I will be verbally reminding him now.
Joseph g – :
anything@parallelminer.com will not reach us. Please send an message via our contact form and will give you an RMA and a return label as well
info17 (verified owner) – :
I received an s7 and am getting a red flashing light and continual beeping. I have ordered 3 asic miners from you, and so far the 2 that have been delivered have not worked. I have also tried contacting several times in regards to this and an Avalon6 that is not working either. Please advise.
s7 Order #14269
Avalon6 Order #14424
Joseph g – :
Please contact us via our contact page. Include your phone number and a good time to call. We might give you a call to make sure the unit is defective as all our tested prior to shipping
frontgecko (verified owner) – :
I ordered four s7s and had to RMA two of them due to them not working.
I received 2 replacements and they are dropping hashing boards every 15-20 minutes. I have contacted your support team to issue the RMA shipping label but am still waiting after almost a week.
Please advise.
s7 Order #12603
Joseph g – :
I will speak with them on Monday and see what is going on. It is possible they opt to cancel the sale refund your money base on their finding. I will make you get an update by Monday
Markerrichard (verified owner) – :
I’ve read the past couple reviews with low ratings, which made me think that this recent batch might be bad, however I got my S7 today and it is operating at 100% of advertised hashing rate. I’m using the 240v 1400 watt Delta power supply and both the Miner and power supply are running nice and cool. Shipping was relatively quick (for the ground option). Lastly Missa is probably the best customer service rep out there! Will definitely buy from here again!
Joseph g – :
Fresh air is always nice. Thanks
info15 (verified owner) – :
This is one bad batch. The S7 is not holding its hasrate, dropping to 3TH and eventually stopped hasting altogether after 24h. Waiting on Missa’s response how to rma this.
Joseph g – :
In the mean time – try to lower or increase your frequency. See what result you are getting
kokibean (verified owner) – :
Since I wont get a call back or a reply to my numerous emails via the contact form since last Thursday 1/18/18. I will have to put my email here. I need instructions on how to return this defective S7 and get a replacement!
We just received our S7 Antminer and it is clearly unstable. We are using a bitmain APW3++ PSU so power should not be the issue. We have multiple S9’s running perfectly fine and they are on same network and under the same environment.
The S7 is running at an avg. of 2,052 GH/S and bounces up and down between 3,500GH/S and 1,000GH/S, sometimes reaching 4,200GH/S. We are running at 650M frequency which is the setting it was defaulted at when we received it. we have changed to 625M and 700M and has pretty much the same ratio of instability.
Visual/Auditory observations – The S7 fan speed ramps up and down A LOT, obviously the output of GH/S increases when fan speed does and vice versa. With that said Chain #2 is always at a 10+ Temp difference to that of Chain #1 and Chain #3, Chain 1 and 3 always is within a few temps of each other. Averaging 51Temp and Chain #2 averaging 40Temp.
Antminer S7 ~4.73TH/s @ .29W/GH 28nm
Order #14998
kokibean (verified owner) – :
I’m following up with my previous review to say that I was contacted same day when I sent them an email but unfortunately the email went into spam and I did not catch it. I am working on troubleshooting steps with support now.
info15 (verified owner) – :
Following up, since I haven’t got any response back about RMA; I have changed the frequencies up and down, but the miner remains highly unstable. Works ok for a few minutes and stops hashing and reboots. An S9 in the exactly same environment has no issues.
Order #14297
vladannedic – :
When will they be back in stock? I am willing to buy as soon as possible. Thank you
Joseph g – :
We are working on our last batch. We should have a small qty up by Feb 1
peashooter (verified owner) – :
It will fail before you make your money back. Two boards died in 45 days and I am SOL.
dabomb6608 (verified owner) – :
Over a month later and still having issues. Purchased 4 units in January (Order # 14287) with one having a faulty hash board(x’s). After RMA’ing the board I still was having issues with it sporadically dropping hash rates with low temps. Was advised to send whole unit back for replacement. After receiving “replacement” unit I am still having the SAME issues with this one. I’ve tried every troubleshooting method I can come up with. Different PSUs, checked all cables, adjusted frequencies, ect. I emailed Albert Monday the 19th of Feb. explaining the issues with this replacement unit. No response. Emailed again the 27th and still no response after 2 weeks.
As of now I am out $800+ on this unit and over a months worth of mining profits.
Albert – :
Hi Patrick,
I apologize in the delayed response. I have your replacement unit currently being tested with your pool and worker configurations. Your replacement will be shipped out after 24 hours of testing if no issues occur with the unit. Please check your email for a prepaid return label for your RMA.
info15 (verified owner) – :
Same issue as dabomb6608; 2 failed repair attempts and the miner is still not holding its hashrate. No repsonse from support anymore.
Very disappointing.
Joseph g – :
Albert, will follow up tomorrow and we will make good on you Sir. One of the problem cause I think, is our tech use our famous Delta 2400/1400 PSU which pushes 12.5volt. Th extra .5 volts does magic for any ASIC miner. We will now kit the Original Delta 1400watts 12.5 volts PLATINUM with all S7 starting Friday. This will eliminate discrepancy between our test and the client
slickster100 (verified owner) – :
Managed to keep it working at full hash for 4 months, one board failed, then 1 month later another board died. I keep it on the shelf to remind me of what “not” to do in the future.
