Another difference between what I have listed and what Bitmain is selling, mine runs a slightly lower hashrate at substantially reduced power and fan noise. Phil can attest to that; he's got one of 'em.

DaveF, PM and we'll work out the details.

Later this afternoon I'll have some full S7 that have been undervolted as well. Overnight stability test looked good.

another difference, if there was any customs charge SH already absorbed this too. no need to call someone at DHL to release Smiley

Oh damn, I did not realize shipping would be so much!  Shocked

Yeah then it's definitely a better deal considering he did the work of undervolting it for you which of course carries some labor value.

Happy mining!

It's $291+ shipping from Bitmain [totaling $357 for me], he is doing $400 shipped. So yes it's a bit more but not much.

Also, unlike Bitmain he stands behind his work. I have purchased power boards and USB sticks from him. You are dealing with an actual human that responds to messages and e-mail. That matters, a lot. I had an issue with one of the sticks, in the end I kind of made it work. But he was perfectly willing to deal with it however I wanted.

Or, what philipma1957 said, oh and use DHL it's cheaper the UPS. And why would you want to trust your packages to a company that has an acronym that is pronounced oops.

UPS joke is funny.

I have better luck with them then DHL or Fedex with overseas.

UPS wants 80.98 to ship this unit
Fedex wants 53.78 to ship this unit
DHL wants 66.75 plus to ship this.

So  it is 344.78 to 371.98 direct from bitmaintech.

I know sidehack  used UPS  for 1st order had zero issues  + 0 fees
I know sidehack used DHL for 2nd order had many issues + fees.

Umm, I was going to say that it's $291 directly from bitmain, but since "he'll take it" ,let him take it.....


371 is with shipping  291 is no shipping.  The gear is quiet.  Very nice in an office that is freezing cold due to too much AC.

I have some full S7s available, all of which have been undervolted and tested for stability (<0.01% HW errors) at a peak clock setpoint. Each has been tested on a DPS1200 PSU with breakout board and 10 cables. The numbers are as follows:

#60: 600MHz (4TH) 1050W 0.26J/GH (sold)
#61: 550MHz (3.7TH) 870W 0.234J/GH (sold)
#62: 600MHz (4TH) 950W 0.235J/GH (sold)
#63: 600MHz (4TH) 925W 0.23J/GH (sold)
#64: 600MHz (4TH) 970W 0.240J/GH (sold)

I'm looking for $450 from each 4TH unit and $425 from a 550MHz unit. This includes shipping (within the US) and PSU hardware - a DPS1200 PSU, interface board and 10 cables. If you don't want the PSU, subtract $75 from the asking price.
