what's the cost for mining 1 btc?
Im mining at Nicehash, how do we turn on the XNSUB option in the miner? im using pi 3. thanks
This is what they looked like before, will post an after later to compare them.
so after 3 hrs its looking good, temps are not bad at all.
Planning on leaving it over night and see what 24hrs will do.
Are you aware is there some kind of protection build in those PSU's. They are running smoothly at the moment. No extra heat or other kind of visual problems.
Is it screaming like a banshee? When I measured the current draw on a 245v line with one 741, it was pulling > 1200 watts of power. Granted, it may not be a 100% accurate measurement.
Maybe they are designed for abuse?
I can't tolerate the noise when they are at 105% capacity, so I went with two PSUs to three 741s.

After setting to +1 I got about 1TH more for my 4 741's. Also hardware error is almost 1% lower for every device. I'm a bit worried of over-pushing my PSU's, because I'm using 1 piece 2400w Delta for every 2 miners. But so far no problems.

Yeah, I think that's too much for the PSU.
I use two of those PSUs for three 741s.

I am already seeing the GHSasc a bit higher now at +1
was at 8092 at 0
now at 8233 at +1
got to give it more time to see but I also see the fans are higher, from 32% to now 43% looking good.
Temps are also 16/80 now

I just changed mine to +1 to see what I will get, room is 65f all the time so cooling is not a problem for me.
With +1, most of mine are at 8.3 or 8.4 TH/s. Some are 8.5, some are 8.2. All are higher than 0.

Okay you have 15
I have a pair I am escrowing and one runs really hot
27/101 100% fan does not seem good to me I only owned 3 of these and I did have one ay 41/101 100 fan but the room was 90-92 f
do any of your units run hot with say 30/100 100% fan
You have 15 at a high setting +1 so I assume your cooling is good

Yes, I have good cooling. They are all under 29/89. When it warms up during the day, I switch the voltage to 0.
You were right, 0 isn't that much lower that +1, but at current prices, I'm happy with the few additional TH.
During the warmer months 0 didn't run any better than -2 did. I guess they self throttle.

EDIT: If I see any at 100%, I change things to cool them down. If that means shut them down because it's too hot, I do.
Can the 741s be safely overclocked with the +1 voltage setting in cgminer?
Assuming there is sufficient cooling, which there is this time of year...

I've been running our bank of (
741's at +1 since the end of Sept, no trouble. There is an additional power draw. At +1 the 8 units together draw an additional 3amps between the two 208v circuits they are on. Ambient intake here is below 60 degrees F, so PCB temps are good. The result of 0 vs. +1 across the whole array is around and average of about 60THs at '0' vs. about 62ish for +1. On my bank of 15, most are running at 8.3 or 8.4 TH/s. I have one that is 8.5 TH/s, and one that is 8.2 TH/s.
Across them all, I'm getting an additional 15 TH/s, which is like 2 free units.

EDIT: What's really interesting is the hardware error columns are lower than when at -2.

Okay I am escrowing a sale of 2 avalon 741's
I think one of them has an issue.
one is in a 70-75f room
temps look good
the other is in a 60-65 f room
temps are higher and intake is lower

Here is another problem with Avalon Controller. It connected and mine through wifi, but i can't get access to the Pi unless i plug the Ethernet cable in. How do i fix it? thanks.
Do you know what the IP of the PI is on your network? As long as the laptop or computer you are using is on the same network you should be able to connect to the PI.

don't bother no seems to be able to do so and get better numbers then the 0 setting.
there are some with 20 or 30 units maybe they did get some good +1 miners
Okay. Well, I've never run at 0. Only -2.
I switched all mine to +1 about an hour ago and they are all running at 1 TH/s more than before. Seriously, all are at 8.3 or 8.4.
You're saying 0 does the same?
