I noticed that when you place an order at SPT, there is some space where you can enter discount coupons.
Are they really offering discount coupons ?
I just bought 2 SP20, I would buy 2 more if they would offer me some discount coupons

They have done in the past, mainly if the units didn't perform to spec or is late shipping. We've also had an existing customer coupon before as well.

I'm also pretty sure that if you buy a big enough order that you will get a discount code.

But this isn't Bitmain, and there are good reasons why not

I have 4 units and 3 s-3's I use winter weather and a garage door

I am running 5000 watts and 7.7th in the garage temps are 89 f

I can stack 1 more sp20 and 1 more s-3

Could be because I'm on 210V rather than 240V?

Socket Voltage 209/209 volt Max Watts 1360 / 1360

PSU's are Emerson
-----BOARD-0----- PSU[EMERSON1200]: 1376->1252w[1252 1248 1248] (->1211w[1211 1211 1211]) (lim=1250) 0c cooling:0/0x0 -----BOARD-1----- PSU[EMERSON1200]: 1408->1252w[1248 1244 1252] (->1174w[1174 1174 1174]) (lim=1250) 0c cooling:0/0x0

Yes, it's because you're on 208V. Notice that your machine is configured to use 1360W max per PSU, but the software is artificially limiting it to 1250W. That's because these PSUs are less efficient (i.e. generate more heat) on lower voltages, so they can't deliver as much power, so Zvi hard-limited them in order to reduce the chance of PSU failure. Spondoolies hasn't done much testing with 208V, so they don't know what the PSU limits should be, but they know 1250 is safe. If you want to try to squeeze more performance out of it, you can bypass the 1250W limit with

Code:

echo 1 > /etc/mg_ignore_110_fcc

Just make sure to reduce your PSU limits in the Settings page first. My suspicion is you'll be able to get about 1280W to 1330W out of those PSUs at that voltage, but I've never tried. 1360W is probably too high.

Yet wierdly on my SP30's I was getting between 1330 and 1360 on the same PSU's and the same power circuit. I wonder if the SP31's have more conservative limits on the PSU's I thought they would have less because the claimed TH output was higher needing more power to get there etc.

Update:
Upgraded to 2.5.33 and now the bottom PSU runs at 1360 but the top is stuck at 1250 still, Hashrate nearly 4.7TH

Going to manually set top PSU at 1330 and see if it sticks.

(Top and bottom being how they are shown in the interface and asic stats)

1330 didn't work, top still lim=1250, wierd.

There's nothing alarming that I can spot in the Dashboard. All the temps are between 85 and 115C.

Should I be concerned about these warnings?

I have quite of heating problem, i lowered the voltage its getting over 35 :/ what ever i do its heating to much

lower your watts.

Temp Front / Back T,B

0.69
Max Watts
175 / 170 / 175 / 170

low setting my power is only 753 at the k watt meter my fan is at 40! still really good temps and watts per gh

temps are great

Hi Guys,

Can anyone help me out.

When I run the "Devs" command on an SP30 miner (running most current firmware) I get the following output.
av=4445838.29,MHS
5s=5923594.28,MHS
1m=5187361.37,MHS
5m=4678246.84,MHS
15m=4526365.21

I notice that the av number seems to be the only number that is accurate. Can anyone tell me what the other number are? I would like to know why the 5s shows almost 6TH/s in this example.

Thanks guys.

Statistics 101?... That aside

As the measure time interval decreases variance increases e.g. A 5 second average reading has much higher chance to vary above and below the expected value than a 5 minute window.

This is in part due to the manner in which the mining software calculates hashrate.

A personal example. I have a particular miner which consistently performs at 500Gh/s both in cgminer avg and pool but I e observed the 5s avg vary from 200G to 1T

I have question about SP20, the front fan looks quite cheap 120mm fan, if i´m not mistaking that fan gives the most noise, what if i could replace it with ultra quiet fan on same size, would it work? less noise? Cheesy

Fan isn't cheap. It's loud for two reasons. Firstly many fans have unique audio properties depending on how they are constructed. This is often referred to as the tone of the fan. The y-s tech fan used has a quite mechanical noise which changes in pitch and volume as the speed ramps up.

Secondly this fan pushes 220CFM, that is a very fast 12v fan. That's a lot of air being sucked through a metal grill over the components then out through another grill.

Yes you can replace it but the fan you replace it with will most likely be just as loud or not as fast and if it's not add fast if won't cool as well.

Lastly it uses a non standard fan header so anything you use will either have to be supplied onto the original connector or the wire running out side the casing to a fan adapter on one of the molex plus on your psu.

That's what I have done. Testing a few different fans so far but none have hit the sweet spot for noise and cooling.
