hey guys.

does anyone of the top of their heads have the best settings for a SP20 for the best hash/watt/fan rate?

Thanks

the best way to go about it is to read the unofficial Sp20 thread.
it also depends on your power cost.
here are the couple of my settings:
~725W (~800 at the wall):
0.65
0.655
0.66
0.658

was fan 50, but could be auto
max volts: 0.67
max watts 188, 188, 188, 188
produces ~1358GH

or
~646W (~710 at the wall):
0.64
0.64
0.639
0.639

fan 10
max volts: 0.649
max watts: 160, 160, 160, 160
Produces ~1231 GH

Thanks for that... power costs are not too much of a issue as its running it off a solar farm so during the day its free

just pay when the sun goes down... the only set back we have is cooling... we have quite a few machines and currently running the machines on the following

----------------

0.60
0.60
0.60
0.60

fan 10
max v 0.65
max watts 200,200,200,200

produces 1206 GH

------------------

If people have any views that would be great.

Thanks

To FC and David, I hope all is well in BitQuan.
I hope you'll emerge stronger and wiser from those trying times.

Guy

what kind of problems does AM have?

Check the Securities forum. There are ~4 threads on fire right now.

any new miners soon ? been holding my cash for new miners for a while

Not much mining equipment out there, Bitmain c1 but inefficient, and ASM which is overpriced.

Zvi --- I am really enjoying 2.6.14 on my SP20s; One thing is needed to make the scheduling work well for many of us home miners;

Can you please add an option to set the fan speed, rather than just leaving it as auto

You can customize the fan speed if you run your scheduling via text files and use cron jobs.

See this post: https://bitcointalksearch.org/topic/m.10358008

I run all of my miners via these crons (8 of them) and it works great.

They were supposed to be code colored (cyan for cold/slow, yellow for OK and magenta for hot/fast). There is a CSS error in there and what is supposed to be magenta comes out as white. ..

I have a question for Spondoolies. When I look at my ASIC Stats page, I see colored values for the "hz" value as part of the "ASIC[:[ 85c (125c)...... ]. If you look back a few posts, you'll see a sample page that illustrates what I am referring to. In the example above, it's a yellow "710hz" or "720hz". On my page, I have some yellow values, some blue values. I'd swear I have seen some white values.

My question is, what does the color mean? Obviously a programmer went to some lengths to do that, and it's just not obvious what the color means. I see nothing related to temperature, and I am way underclocked, and have a mix of blue and yellow values. In my case the blue values are always less then the yellow values, but that's about the only correlation I see. I didn't see anything in the recently released SP20 Users guide that made this clear.

What's going on here?

Hi dear, all
i have two sp20.
This morning i see both miner offline, i check them and i see psu are ok (each miner has own psu), network is ok but just in case i restart my adsl router where they are connected.
Then i try sd boot, then sd recovery and nothing happens.

Its always same, led`s for network blinks, but orange and green miners led not lit, not blink, nothing.
Looks like completely not responding. Also minner didn't take ip address from router(i check this in my router GUI)

Any help please, i email SP tech, but meanwhile any help will be nice.

did you check the ethernet plug connection? that port is somewhat flimsy.
after that, maybe switch off psu for 20sec, then back.
finally, you can still use dhcp, but could reserve the IP link to MAC address in router settings, then it will not jump to another IP with potential conflict. It shouldn't do that anyway, but it is theoretically possible without such reservation.

This is why high power GPU's have 2 pcie power connectors usually one 6 pin and one 8 pin. Not totally necessary but they do it for consumer protection against lawsuits.

I never melted evga cables. But I melted seasonic cables at the psu side.

Loose cables can do it.
As can high long loads>

(sounds like a porn film)

hehe .. You're spending way too much time with your miners Grin

yes I've set them to 3. But temperatur was never over 85° on the downclocked ones, they are pulling fresh air and it is maybe 6°C at the moment outside.

I think it really might be a lose connection on the cable. Yesterday I moved the two SP20s. Maybe during that one of the connectors got lose.

it could be loose connection but 3% is low and 600 watts on two cables is high.

I have run 2 sp20e's on 1 evga but I staggered the loads and upped the fan. Hard to tell which was the cause here. Maybe a little of both?

But I do believe 3% fan and 600 watts on two cables is high. I also think that the connection may have been less then ideal due to movement you mentioned.

Yeah it might really has been caused by a little of both.
I'm powering each Sp20 by 3 cables, one 2x6Pin on each SP20, the other 2 cables are normal ones. But that means that the 2x6-Cable does load nearly 300w. Didnt think of that..
