On SP30 the unit "learns" the PSU, so you can set initial value to 1360 (that is how we ship them).
The unit will settle around 1320, depending on temperature.

Does it recheck for this value?

What happens if it is 10°C cooler during nighttime?

Would the amount of available 12V power increase if you put it onto a 252V circuit?

Will a cooler ambient temperature increase PSU performance?

If it's 10°C cooler during nighttime, then the performance during the night will be a very small amount lower than the machine is capable of, because it will be running at settings which are safe for daytime use. If we change the firmware to be temperature-sensitive, then this would no longer be true.

I've asked these questions before. I would like to see context-dependent learning or a temperature coefficient added, but it probably won't be a very large boost in performance.

Harel doesn't think 252V will increase available DC power. I do. He's probably right.

I got the firmware for my SP30 upgraded and I got past the 1080W hard-coded limitation that was on it earlier. I'm now getting 4178 GH/s on 122 V while using 2752 W (2*1376) at the wall for an efficiency of 0.659 J/GH. The top Emerson PSU is limited to 1190 W, and the bottom is limited to 1170 W. I doubt performance on this machine can be improved much beyond this point without switching to 200+V or drastically improving the cooling. Last I saw, the intake temp was measured by the SP30 at 28°C. It will be interesting to see how this machine's performance changes once it's running in the DC proper.

Is your sp30 at ThorDC online yet?

If not, just spam them until you get your setup fee removed and your miner online.

[Marvell1]

Anyone else with a Aug batch order have it showing as "Restocked" now ? previously it was listed as Unfulfilled

I do not think that context learning is worth it in terms of stability vs` value.
Those are the most expensive GHs, so even if you have 10C difference, and it translates to 20 watt (1.5%), you will get 0.5% difference (25Gh) - that is not enough to justify the added complexity.
 
But one can do this in cron: create several /etc/mg_custom_rate_xxx files for different time of day and set symbolic link from crone at every few hours (just remember to restart miner_gate after that to reload settings). The system will update relevant file every PSU 'failure', so you should get exactly what you want. But I am not sure restart downtime will pay for itself.

Update to latest FW.
If it is still restarting when PSU limit is under 1300 (front page) or after 24 hours - contact me.

[Biodom]

Disconnecting the PSU's power will reset the SP30s knowledge of the PSU's limit, and will cause this algorithm to start again. If you change the cooling conditions for your SP30, you should power cycle your PSUs so the SP30 learns its new limits.

I didn't explain myself correctly in mails:
In order to cause recalibration, go to "settings" tab and set high PSU limit (1370W is over the top for 95% of PSUs).
It will take it down again to it's possible maximum over the next day.


Note that the hash rate is more expensive the higher you raise the watts.
You can get ~4TH for 2300W, but the next 600W will only provide 0.5Th - much more 'expensive' hash-rate in terms of power.
So I guess for 2500 the system will give about 4.2TH. If you pay 0.15$ per kWT, you still better running 4.5TH (100$ more). If you pay over 0.35c per kWT, you better run 4.2TH.

Is the info above at 240V or same for 110/120V (for lower Th)?
In other words, if I run Sp-30 on two 15A 110V circuits (ostensibly up to 2640W/24A from both at the wall), what would be the expected hash? do I need to do some mod to remove power limit? I would like this info so I can compare the economic benefit (or lack of it) for hosting vs home.

[Collider]

You will get around 10% lower hashrate at 120V compared to 240V.

As far as I know you don´t need to do anything fancy to use it on 120V.

[Biodom]

You will get around 10% lower hashrate at 120V compared to 240V.

I get that (4.1Th at 110/120v), but would you use 2500, 2640 or 3000W at the wall to get there?

I'm now getting 4178 GH/s on 122 V while using 2752 W (2*1376) at the wall for an efficiency of 0.659 J/GH.

This is on 120V.

There should be around a 3% difference in PSU efficiency vs 240V, and obviously a total of around 10% increased power provided on 240V.

This all works out to the sp30 running at 4.5TH on 3kW of power at 220V+.

Total energy efficiency should be slightly better at lower hashing speeds, but even better on lower speeds and 240V compared to lower speeds and 120V.

Super, thanks, I just don't know about 122V. Typically, it is 115-118V, but i checked my house, and it is, indeed, 121.5-121.8V.

The question is whether the pin setup is compatible to the PSUs normally shipped within the sp30.

It would obviously not be feasable to attach an adapter (that doesn´t yet exist) to a PSU (that will then no longer fit into the miner housing)

I read on Dogie's SP30 setup guide that the SP30s come with "either 2x Emerson DS1200 or Murata D1U3CS-1300F-12 server PSUs with 34 pin outputs". I found Murata has a 2200w 1U server PSU with 34 pin connector. Could be compatible? But they are not cheap like the Delta...

I though the ASICS are at near max power using the 3000WAT , would you not risk frying them with far more juice than is optimal ?

[zvisha]

We have sent some units from our DC to clients with version 2.2.27 today.
Please do SW upgrade once you get them before you start mining, or it might learn non-optimal PSU settings.
