Moin,

Ty again! I hope you didn't have to type it, just copy&paste!

Will report back!

Just go up/down 4/5 steps and you will have the next +- 100 Mhz

Have a nice day

Moin and Ty!

I will try them next weekend.

Can you give some good working MHz@V settings for the X1?

Moin

for monitoring (very accurate numbers): i'am using cryptoglance and an raspberry pi

for watching the speed/frequency ....i'am using the webinterface (your  prosperos ip x.x.x.x)
there you can easily restart the miner.

For manipulating the config of the miner use putty and winscp

log into the miner and cd to bamc

nano bamc.conf  all the parameter are explained (here is the voltage parameter)
nano pools.conf (for pools settings)
nano cgminer.conf (look at the end of the file there is the parameter avoiding the ramp/ minion-freq: your speed)
nano cgminer.sh (for api setting's if you want to monitor the miner)

Thats all

Moin!
How do you avoid the ramping?
Tested now [email protected] that will go near 80 GH/s. Waving around 70Gh/s to 90Gh/s ....
Maybe you will provide how to set these things up, which programs you use and which files i've to edit?

Greetings

Hi,

at 800Mhz it should give you about 80 Gh/s. Maybee you should play a little bit more with the core voltage.


At the moment i manage it  to set up the miner so it start (after reboot) with the desired speed (ex 500Mhz) and did not ramp down
from 1000Mhz to 500Mhz in 100Mhz steps. So the miner is much faster at is desired speed.

My miners ( 6 X1 and 3 X1.5) are running now at 475Watt (out of the wall) at 600 Gh/s = 0,79
(including 16 Port switch /raspberry for monitoring and Powerlan-adapter for internet)

This is far away from modern miner but a lot better than in default configuration.

6 Miner are throwing only a dozen hw-error a day..... total less than 0,0002% (i count it for a week)

Yes i know bitcoin-mining will give me not back my spent money even not for the power-bill but i'am still mining my
favourite altcoin or selling my little hashing-power at miningrigrentals.

I manage it to get two old x1 running again from scratch (flashing via sd and via usb-port)
Sometimes the prospero controller-board is in a non operational state after power-failure or power reset.
It seems that the software-version 1.17 is the most stable.


Have a nice day

I got an X-1 running stable by [email protected] doing nearly 70 Gh/s.

Hi,

I'am now fideling around (for a few month) with a bunch of Ba prospero X1 and X1.5
I know these miners have a bad reputation (unstable/broken after power failure/hard to manage) like the
company which sold them, but i will do it anyway.

Maybee some folks outside are still using these miners?
The are very well done, do not need an extra controller, could be set up easy via touchscreen.
Have an Wi-Fi controller with antenna. The fan is very big and not that fast so not that loud.

So just putting them into your living room would'nt  be notice by anyone  except at night because of their fancy lights
No extra cooling even in hot summers.

I'd like to share my experiences and my efforts to get these (in my eyes) very nice little miners to there 'sweet' point
Due to the cost for power and the very fast climbing bitcoin difficulty my hints and tips will be  not in the direction
off tuning to the maximize hashrate ,it will be tuning to the best efficiency (watt/Ghash)
Unfortunaly i'am not an owner of an BA prospero X3 , but i think my handout will be also applicable for this unit.

I will also give some tips about managing these miners  via command line (ssh)
And how you could easy manage these miners with a raspi/orangepi and some tools.

Hopefully there are others sharing their experiences here.

I could also give some hints and tipps if your miner is not hashing anymore after a powerfailure

The startpoint was:
6* X1  and 2* X1.5  at factory default

In this configuration the X1 will give you 100 Ghashes at about 100 watt at the outlet (temp of the chip is 60 degree celsius)
the x1.5 gives you 150 Ghashes at about 142 watt at the outlet. (temp of the two chips is 60 degree celsius)

So in total this little mining rig has 900 Ghashes at 884 Watt not including power of 10 watt (for the raspi a switch and a powerline-adapter)

So there was a faktor of 884 watt/900 Ghash = 0.982

At the end of my travel i settle down at 390 watt/500 Ghash = 0.78

In that configuration the X1 will give you 50 Ghashes at about 38 watt at the outlet (temp of the chip is 25 degree celsius)
the x1.5 gives you 100 Ghashes at about 77 watt at the outlet. (temp of the both chips is most of the time 25 degree celsius)

All miners are running with 0.005% HW-errors and rockstable

I think i could go just more down  even to a faktor of 0.65 or even lower.

Have a nice day
