Does anyone in the US know the max these will run on 110V? I think it was 1.35 Th/s.

I noticed in the tech blog a May batch cannot go back to a FW prior to 1.3 so using an old FW (voiding warranty) before the rate limiting was inserted isn't an option.

Why you guys keep talking about 110V in US. Everything I read says that US has 120V/240V with 120V powering living rooms and 240V-dryer, washer, AC, oven, etc.

Few houses run at 120V and normally something less. But even at 120V Spondoolies FW limits the total power draw so the hashrate is limited to something less than the 1.5 Th/s achievable on 208V or higher.

Do you know where I can find any official information about hashrate limited by FW on 120V ?
I carefully look to the Product page, FAQ, Technical Blog and Company Blog but I was not able to find anywhere a statement about lower hashrate on 120V.

I'm asking because I was not aware of such limitation ... I payed for 1.5Th but I'll get ~1.4Th due to slow-slow ASICs and now I find out that actually I'll not get more than ~1.35Th because I'm using 120V ....

Now I'm wondering if there is similar hashrate limitation for SP30 ....

There is any way to disable FW limitation to be able to get full hashrate on 120V ?

The limiting factor is present in the main Hardware thread for some time. You paid for 1.5Th and you got 1.4-1.45Th. It's your job to feed the power to the miner

I dig through the main thread and found the FCC explanation which make sense.
However, the technical specification page for SP10 suppose to have this information listed there instead of a note on page 44 from the forum thread.

Lower performance on 120V is expected anyway so this is not a big deal for me on SP10. On the other hand, I start to be more concerned about SP30 which need even more power and it is also listed as FCC compliant. I hope SP30 FW will not limit power usage in similar way.

No. The PSU requires 220v to function at those levels, if you do not have 220v I would sugest finding a hosting facility for your units.

+1. Most power supplies run 3-6% more efficiently on 208V power than when using 115V. This translates to the PSU being able to push out some extra wattage safely.

(for example; the DPS-800 PSU runs 800W on 100-120V power but is simultaneously rated for 1000W on 200-250V power

I have information that that pricing will be good for all S2s come end of may, not just the GB units.

End of may is 2 weeks ahead. We don't know what SP-Tech prepares for the end of may.

If I could get 6 months free hosting I'd buy

All you need is an electrician to either run a new line with 200V from your breaker box
or I think alot of lines can be converted to 220 by combining circuits if the wire is big
enough. If you have an AC unit there you will want 200V to run it too probably.
200V is better since the amperage use will be lower. I think at 1200W its about 5A
on 200V but 10A on 110V. Which should mean if I have this stuff down correct, is
you could effectively run more wattage on 200V using the same amperage. Also more
efficient on 200V I think. Just call an electrician, they can probably install a 200V line
in less than a day. I'm getting a new one run today for the AC unit and ASICs here.
