Bitmain S9 hashboard Antminer s9 Hashboard. Working tested hash boards On sale!

Description

Dropped price to 149.00! Free Shipping to USA!
Shipping will be free with fedex or usps.com depends on what works for me not you.
Price is fair so no returns.
BTC is volatile so if btc price crashes you don't get to do a return.
I tested boards with  2019 bitmain firmware.
Each board works and was tested at 2 speeds
Low Power Enhanced Mode
HashRate+0.5Ths
I also tested with braiins firmware at freq 325 and 625
you can see the braiins testing for the boards in the photos.
They do freq 625 under 90c in a room that is 90f
I suggest running it on 220-240 volts as it will hash with less stress on the psu
If you run it on 110-120 volts you will need to down clock it.
I prefer a buyer that is honest and not a new buyer since this is a crypto item.
I have some  for sale I will be listing more mining parts as I am getting rid of the s9 gear due to summertime power rates and heat.
No returns as this is crypto and these are tested to work
