i will try this on tuesday.

So I am home.  I tried a btc order and seemed to not received a btc credit.

I will let it expire

I have sent them multiple copies of the order. it was a btc order. i did all paypal orders after this,  but if you are correct
i could try a btc order now and see what they do.

i don't have access to any btc as i am on the road.

i will be home in a few hours i can try to order and see what they do.

Anyone using ryzen 9 3900x to mine?

i built three rigs.

gear seems pretty good.

we need to stick together and keep asking for what is due to us.
I am on the road and will be home later today. When i get home i will review my notes on my pc.
i will post here and update. i will also contact them and ask for updates.

Truly frustrated on this. as i am not only waiting on my 114.
i am waiting on my 865 and two late units of gear. now nine days late. 100 th at 9 days is

900 x 0.00001915 =. 0.017235btc lost in earnings.

I would love to test it out.  I ordered a spare s17 controller for testing.

i am yet to,see the 114 credit or 114 refund for that purchase.

2x s9k don’t have my refund or credit.

i have purchased

2x t17e- late 8 days and they need a 865 adjustment.

1x t17 - not due to ship this generated a 150 coupon

1x s17 - shipped arrived and it generated a 683 coupon
1x s17pro - shipped arrived and it generated a 368 coupon used the 150 coupon here

1x s17pro - shipped arrived and i used the 683 coupon
1x s17pro - waiting for it to ship and i used the 368 coupon

1x t17+ not due to ship i used a 375 coupon that no one has explained to me where it came from or why i got it.

---

so i have 2x 17e that are 8 days late that i need an 865 refund
i have 2x s9k.  that are delivered and need a 114 refund
i have a mystery 375 coupon issued that i spent.

while the unexplained 375 coupon was nice.  but 865+114=979 that is not very good.
also the two t17e eight days late. thats about 130.

so 1109 downside and a 375 upside means i am short 734.

i also think the s17 pro i purchased at 1999 that was delivered may generate a 400 dollar coupon due to the price drop to 1599.

what’s annoying is i am ready to shop and buy more s17pro if they fix the mess they made.

i have power for more gear. maybe 6-10 more units.

i got the exact same email. yet to get refund  in btc.

as to purchase of a coupon
i self mod my sales threads 🧵.

i never lock them unless the items are sold or no longer for sales.

If you lock a thread and are looking to sell not allowing conversations in public in many cases you are a risky seller.

during spring in 2018 i escrowed the sale of 300 coupons. many for the same guy.

i would never send btc first to buy a coupon. i would tell people i want an escrow.

this thread is more about dealing with bitmain and getting proper refunds. credits , coupon discount etc.
it is also about using your coupon correctly.

altough i guess one could argue that selling one of your multiple coupons does belong in this thread.

higher frequency is more  power 💥 hungry most likely if you s9 is allowing you volts and freq you need to raise volts higher as you lift the freq.

it varies unit to unit based entirely on the chips in your unit.

i have one unit with braiins software which allows freq and volts for each of the three boards.

i could do

8.1
8.1
8.2

and set a low frequency getting 10th and 815-825 watts.

it was my best underclock unit.

i can not really give you a formula that would be accurate since yiur chips on your boards can vary a lot. 5-10%.

i can tell you higher frequency will need more volts.  then 8.1 or 8.2

7.9 is lowest
9.4 is highest IIRC.

yeah the a841 was really good to use for a heater.

in many ways my favorite miner from avalon.

we are getting a pair of  a1066 units soon. i will see if i like them.

Selling your coupons should be done in the marketplace here using an escrow.

As of today no movement on my t17e's   they are now 7 days past  the 1-10 dates.

100th x 7 = 700th x .00001915 = 0.013405 loss of btc  for me and my partners.

And this order is due for a 865 usd refund.

they sent me a 368 and even a 683 i spent them both.

the s17 pro is coming from malaysia is 1599 and no trump tax.  just a small 30-40 dollar import fee shipping is 120.

nets about 1750 run on low it is not very loud. pulls 43 th an efficient about 37 watts a th.

reminds me of the godfather: “ just when you think 🤔 you can get out they pull you back in.”

not sure but why not sell the coupon for 132 you could get 132 easy.

368+132 = 500 you are 20 bucks better off. i think   🤔 you can get 132 for that coupon.

as for me getting a credit i don’t expect to see it for a few more days.  i will ask them on tues for info if they have not paid it.

i am more concerned about my order for 2x t17e.

sold one more this one was sold to sarcheer.

a 30-31 th miner on high.


i have four left

2 do 30-31

2 under preform

22-27 th.

use

edit let me look more

this works

https://www.amazon.com/SF-Cable-Prong-Adapter-60320-C14/dp/B004OC579E/

all below is good

and this

https://www.amazon.com/NEMA-5-15P-C13-Splitter-Cord/dp/B00W5LJQKM/

with this meter in-between

https://www.amazon.com/Electricity-Monitor-Voltage-Overload-Protection/dp/B07DPJ3RGB/

don't run it more then 30  - 60 minutes to get your readings.

It is not good enough to run more then 30 to 60 minutes.

So attach the  plug to one of your 13c power cables  and to the meter

then attach the splitter to the meter  then run  for under an hour should work. may not

This is why I am advising everyone to screen shot all orders not yet shipped and keep for a reference,

Somewhere someplace  I read a we ( bitmain) reserve the right to change terms of any and all coupons.  I am looking for it.

BTW my 2x t17e are now 5 days past shipping date.

The s17pro set to low speed is okay.

Or a modded s9 see my s9 mod thread.

Bump

I am buying ryzen 9 3900x for 500 + 33 = 533  and I get 50 + 30 = 80 in rebates so they cost me 453
I did bios upgrade on my asrock x370 board cost = zero
I sold the ryzen 7 1800x for 106

453 - 106 = 347 for upgrade  from 1800x to 3900x   The pc unit uses 110 watts  to mine.  that is 2.64 kwatts a day or say 3 kwatts.

 at 15 cent power I pay 45 cents to run it.    so 100 cents - 45 cents = 55 cents a day pure profit.  Oh for the next 4-5 months  I will save 10 a month  so 50 bucks off my heating bill.
It is quiet and can mine for years with no issues.

PLUS IT IS  a solid pc.  I have 3 at the moment.  I may do 3 more.
