ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH

3. Server PSUs are a who other matter. I wouldn't even bother with a 550W server PSU, since you can find 800W server PSUs for that price just as easily. You just need to be willing to do some extra work to get them working.

On the mark there ..... just happen to have a ton of them 550W types in my shed that were powering my S3's that I have now disposed of. (they actually worked well on the S1's as well!)

The S5 won't get 1.3TH/s at 650W though, unless your unit is significantly better than mine are.

Hmm I get 650W (119V) on my KillAWatt running 1245GH on a 1000W LEPA Bronze supply with 375mhz.  I did briefly run 390/400mhz with a Gold supply and thought I was averaging about 1.3T/650W but maybe I'll go back and double check...

Thats what I don't get all the SP20 love here.  It takes 960W @ the wall for 1.4/1.45TH on my SP20s.  So I feel like 300W to gain 100/150GH is just a bad deal on the SP20.  Heck thats nearly 50% more power required!

I dunno I just haven't touched my S5s in two weeks, and they are solid.  The amount of messing-around I have done on the SP20E and the number of firmware updates/fluctuating GHs numbers, etc -- well lets just say it reminds me of the early Jups and all the tweaking that was required to get those big chips all happy.  

The hashrate numbers sound about right. Mine are getting a 12hr average of 1271GH/s @ 375 and 1311GH/s @ 400, so you'd expect ~1291GH/s at 387.5.

In that case, if you have a bunch already and they're all wired up, you might as well just use them. I have a bunch of 450W server supplies kicking around that I used for S1s as well, but they just have wire leads and I'm not going to bother putting PCIe plugs on them.

I suppose you are right ... still, I am getting 1350GH/s average (as opposed to the 1312GH/s I got from a single 850W server PSU), so never know, tweeking up the voltage (a simple pot twist on the 550W's!) may yield a bit more yet!
Still think 2 550W's are more efficient than one 750W / 850W even 1100W powering an S5 .... and over 6 months, that may be something. Gotta get that killawat.

I have to try a more powerful power supply unit.

What frequency are you running that thing at? Also, I cannot see you having more than 2 blades, but I may be wrong, how many blades are those?

2580GH/s .... ? Care to post a screenshot of the webUI?

Impressive .... I suppose the real test on that setup would be the longevity of that PSU and whether you'd need a 1700W / 2200W (80% / 60% load respectively). But yeah, that's approx 690W for a "standard" S5.

Well I prefer to push my SP20 harder now and lower then later (diff jump). It always depends on so much factor ... for me electricity is cheap, so it's a no-brainer (~1100 watt for like 1560GH)

The benefit of the SP20 is that at about the same speed as stock on the S5 it is equally efficient, and can operate at further efficiency (it gets close to 0.45) or ramp up its speed by 50% if theres a reason to want maximum hashrate even if its less efficient (such as for the paycoin spree, or if we saw a 50%+ price rally)

The S5 needs to be priced cheaper than the SP20 i think. Both are excellent products but this antminer is disadvantaged in a few ways

In case anyone needs to enable the buzzer and flashing light in the same way the FindYourMiner app works but doesn't want to have to use windows I threw together a quick ruby script that does the same thing from command line and commented it as best I could. You will need to know the IP of your miner beforehand as this won't scan for it like the FindYourMiner app does.

Code:

#!/usr/bin/env ruby

# Make sure net-ssh is installed "gem install net-ssh"
require 'net/ssh'

enable_buzzer = "echo 20 > /sys/class/gpio/export \n"
activate_buzzer = "echo low > /sys/class/gpio/gpio20/direction \n"
buzzer_on = "echo 1 > /sys/class/gpio/gpio20/value \n"
buzzer_off = "echo 0 > /sys/class/gpio/gpio20/value \n"
enable_light = "echo 45 > /sys/class/gpio/export \n"
light_on = "echo 1 > /sys/class/gpio/gpio45/value \n"
light_off = "echo 0 > /sys/class/gpio/gpio45/value \n"

loop do

	puts "Enter IP to Enable Buzzer"
	ip_input = $stdin.gets
	ip_address = /([0-9.]+)/.match(ip_input)
	ip_address = ip_address.to_s

	# Log into miner over ssh using default credentials
	Net::SSH.start(ip_address, "root", :password => "admin", :paranoid => false) do |ssh|
		puts "Verifying Model"
		# Read model information
		type = ssh.exec!("sed -n 2p /usr/bin/compile_time")
		# Print Model
		puts type
		# Verify miner is actually a S5 before attempting to turn on the buzzer
		if type.strip == "Antminer S5"
			puts "Enableing Buzzer"
			puts "Press Enter when done"
			# Enable gpio interface for buzzer
			ssh.exec!(enable_buzzer)
			ssh.exec!(activate_buzzer)
			# Buzzer stays on until shut off
			ssh.exec!(buzzer_on)
			# Enable gpio interface for light, may not be required to turn on light as it appears to be enabled by default
			ssh.exec!(enable_light)
			t = Thread.new do
				# Loop to keep the light flashing until done
				while true
					# Light does not stay like buzzer does it only flashes
					ssh.exec!(light_on)
					# Wait half a second between flashes
					sleep(0.5)
				end
			end
			# Wait until Enter key is pressed
			gets
			# Kills loop thread which makes the red light flash
			t.kill
			# Shuts off buzzer when done
			ssh.exec!(buzzer_off)
			# Shuts off light, may not be needed since light appears to stay off by default
			ssh.exec!(light_off)
			puts "Disabling Buzzer"
		else
			puts "Wrong Miner Type"
		end
	end
end

Those are hot temps.

From what I understand the temperature sensors are on the opposite side of the board than the asic chips. Since he is using water blocks to cool the chips, he won't get an accurate reading on temperature. The heat is pulled away from the chips more efficiently with the water block than with the air cooling heat sink.

That doesn't really make sense. A water block or an 'air block' would make no difference to how the temperature probe reads in relationship to the actual.

It is what it is, try and get your head around it!
Sensors in a standard S5 are also cooled by the fans, thus a lower reading, whereas in a water cooled setup, not much air movement is concentrated on the boards (aka sensors), so the readings are going to be higher.
In any case, if this were not the case, then we'd see that reflected in the other stats- hashrate, HW% etc, but we don't.

Cooling isn't there just for the chips, so if you're saying that its okay that the other components are too hot because the chips themselves are cool, you're gonna have a bad time.

To answer your other statement, we don't usually see temperatures reflected in those other stats anyway. Plenty of people using low RPM fans run at similar temps without any noticeable effect on the telemetry.

Another dogie-waffle response ...

The hashing chips are the primary heat generators in the S5, and the water cooling block (like the air cooling) is targeted at the chips. As was pointed out, the sensors are on the opposite side of the board and the reading they give in an air cooled setup is subject to the active air cooling, i.e the fans, which is not the case with a water cooling setup as the fans are mounted on the radiator (that should not be too hard to understand really).

If the temps are too high, you'll get HW errors when the chips fail to return a result (which will also reduce the reported hash-rate), and in the extreme case, the unit will stop hashing aka thermal cutoff .... and that is where temps are reflected in the other stats in case you were still trying to figure that out.

Dogie- You are wrong. Again.
How do you explain this ?  My cooling water temperature is 32 degrees.

The reason I would expect that you'll see higher temperatures on the back side temp sensor is that since the primary heat path is through the external radiator, the unit fans that cool the boards are running much slower and thus the PCB and temperature sensor are hotter. If he was still running at 3600 RPM with the stock S5 fans, you'd still expect to see lower temps with the water cooling.

With the temperature sensor should be done so

and the readings will be much lower.
