Okay  I got this r4 in dec.  a board died   I ran it on one board. Finally decided  to send 1 board in for repair.

board came back  and it works but so so.

the firmware is rolled back to last year so you have full frequency control.

The one board can do freq 600 and give 4000gh

but if you do that  the repaired board gives 1500gh with tons of x's

It does 6300-6500 stable  with 670 watts  on a kwatt meter with a plat psu.

A little more info on it..  I will ship for free to usa.  I would want btc  to my address

https://blockchain.info/address/1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje


1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje


Not sure what to ask.   at 6400gh  it is about 75% whole

based on 2000 on amazon and ebay  75% is 1500

That is too high.

Based on  900 for an avalon 741 direct  from  cannon.io --- it cost 714 + shipping + rasp pi


  the avalon  does 7.3  but burns  1000-1050 watts vs my 675 watts

so  my slightly off  r4   with the old school firmware  kind of matches  the avalon 741 direct from avalon.

there is a shot a firmware upgrade  could improve it  to 7500 or so.

if I ask 900  usd in btc   it should sell  no questions.

I am looking to move to all nvidia 1080 ti's and or amd vega's.


so over 900 and under 1500  seems to be fair to me.

pm with offer.  in that range.

I  see I can get a new s-9  on a pre order for 1099 + 68 to ship = 1167 usd  it will arrive on September 20th 2017.  That is 75 days.

So your  gear comes in a few days.  So it is a 75 day head start  but you are 6.5th  the new s-9 is  13.0 th

@ the yankees  win

you are correct so lets compare  and come up with a better pricing for the r4.

It is really quiet   fan is under 1400 rpm.  What does this mean?  For many  not all  it means free power if you need a space heater in the office.  Many people do.

So I can make a 0 power  chart for it.  We all know the s-9   needs hosting for many people so I can make a 6 cent power chart for it.

This is fair comparison  for   the office user  with 0 power cost  against a hosted user six cent power cost

If you do not fit these  you need to do some more work.

So the lower r4

at 0 ------- power
at 5%----- diff
6500gh--- hash
675 ------ watts
13 btc --- blocks based on kano.io
2502 ----- usd price

will earn  after free power

 9-14 – 9-20 (70 days)      358.9 usd
11-22 – 11-28 (140 days)          638.0 usd
1-31 – 2-6 (210 days)               855.8 usd
2-21 – 2-27 (231 days)             911.1 usd    so a decent chance of roi  in  8 months

if sold for 900 free shipping and the buyer has 0 power  since it runs in an office.


so if you buy  the s-9 preorder  and use  6 cent hosting power due to noise

will earn after 6 cent  hosting costs

9-14 – 9-20 (70 days)         0 earned
1-22 – 11-28 (140 days)  413 earned
1-31 – 2-6 (210 days)      702 earned
4-12 – 4-18 (280 days)    894 earned
10-1 – 10-31 (476 days)  1084 earned

since it cost  1167  it does not break even at six cent power.

lets go to five cent power


7-1 – 7-31 (384 days)   1181 earned

lets go to 4 cent power  

 5-1 – 5-31 (323 days)  1199 earned

lets go to   3 cent power

4-1 – 4-30 (292 days)    1224 earned

finally 2 cent power

3-1 – 3-31 (262 days)    1218  earned


So  if you have 2 cent power  and don't mind  the s-9 noise  it is a better deal at 1167  and waiting 75 days for it.


But if you have free power  the used r4 here  at 900  and free shipping is a pretty good deal.

So  send me a pm  with an offer over  900 and under 1100 usd   in btc,    Then pay my btc addy
