Is 208V the closest you'll get if you have a 3 phase supply? You ever get any problems with other components?

I'm on a 3-phase supply, and our machines are getting 254V right now. Yesterday and the day before, they were getting 259V-263V, but I decided that was a little too close to the limit of what the PSUs are rated for, so we turned it down a notch.

It depends on what kind of transformers you buy, and what electricians you employ. Many transformers have taps you can use to adjust voltages. Many electricians will only let you use the taps to produce voltages as close to what's written on the transformer nameplate as possible.

Sorry for the repeated question SP TECH, but I need to make a decision.   
I have 208V power (three phase 460 transformed to 208V).   Your post about SP30 having a programmed cutoff at 210, is that a hard number?   Will 208V see lower results?   If so, how much lower?   I can re-tap each of the transformer windings to get it up to 220V, but there is a cost to that and I need to figure out if it is worth it.

208 is a bit low, and might have some small performance impact (~2%) - it really depends on exact voltage.
We will investigate next week to see if we can improve that.
My Units are not showing any noticeable impact on 208, Im happy to let you remote in and play with the settings if that will help Smiley

If you are in the USA and have 460V 3 phase it will most likely be 208V off each leg (120 X 1.73 = 208V).   The transformers are much more common and much cheaper.   You can have an electrician re tap the windings to get it to 220V in each transformer but you have to decide if that is really worth it.

You get 208V on 3 phase Y (wye) setup. The 240V 3 phase is usually a Delta setup.

Chances are your commercial service is a 208v wye service, which is the most common 3 phase transformer configuration. A 240v delta transformer configuration, which is not as common, is in place so it uses only 2 transformers for a three phase system, where a wye setup would need 3 transformers.

Older neighborhoods use 120/240 Delta 3 phase systems. Two phases are 120V to ground. One phase is about 200 volts to ground (wild leg). All phases are 240 between them. Newer neighborhoods (post mid 60s) use 208V.

One way to accommodate a secondary (voltage) Delta connection is to get Three Single Phase transformers and connect them in a Wye/Delta configuration. Adding a transformer is not an easy feat for most of the non-licensed guys .. and they might void insurance / contracts. Definitely not the average DIY gig.

We're not blaming anyone or any company. The nature of the business doesn't allow shuttles and first productions runs.
As explained, all the wafers lots until and including September suffers from the same, easily fixable, production issue.

Clueless!
My vague statement was correct. I don't reveal the full details on purpose.
In about 45 days (October batch) the SP30 will be 5.5 THs
(The limiting factor will remain the PSUs. The RockerBox has much more potential for over clocking)
This will be done without mask fix, just production tuning.

jtoomim more or less got it right.

My point is that TSMC will not have 'accidentally' botched 3 separate batches of lots (August, September, October). Remember, these are the same 28nm lines that Qualcomm and Broadcomm use. The notion that it is TSMC's 'fault' is simply a convenient excuse to a design mistake. I have no doubt that TSMC is capable of a retarget of your LVT devices to meet your original performance target. However, that 10% increase you were hoping to achieve with a post engineering run retarget has disappeared. Guy, I applaud your ability to perform damage control.

jtoomim, yes my name is intentionally chosen to troll. That doesn't delegitimize my arguments. Source: I run fab sync for a major US semiconductor company. You don't have to believe me, but you can do your own research on the topic.

How do you know that they didnt get all the SP30 chips in one batch? And it just takes this long to build and ship them. Plus I think its just August and September, the October batch is purported to be back up to 5.5TH so is probably separate. Thats the way I read it anyway. Smiley

I don't think TSMC makes too many mistakes, they are not worth 106 Billion dollars for nothing.

thats the catch...it is NOT a mistake by TSMC if they are as spondoolies said 'within spec' just at the low end of that ...I"m sure if they were truely out of spec
spondoolies would have other options....such stuff is likely written by TSMC to benifit them in slippage one direction or the other on performance anyway imho.

I don't know whether the mistake was in manufacturing or in design, all I meant was that it appeared to me that the concept of them making 3 batches with the same error would, as you say, not make sense. Either from SPtech's POV or TSMC. So I was suggesting that the erroneous batch was a single batch for Aug/Sep production, hence why it is being corrected in the October/Nov batch of chips from TSMC.

So say it was a production error, its only one mistake, not 3, not "too many" just one. Of course it might not have been TSMC's fault at all, but again thats not what I was talking about.

My sp30 travelled from Israel to jtoomim´s WA hosting facility in only 2 days. (thank you Spond∞lies and FedEx)

A short review of my hosting experience so far can be found in the hardware hosting comparison thread:

https://bitcointalksearch.org/topic/m.8361310
Also: I was faster than you, RoadStress

I will compensate Collider  Cool

So you guys suggest http://toom.im/ for best solution for SP30?
What happened to the Iceland data center? Aren't you using this for SP10?

We are decentralizing!

I am still running one sp10 at the Iceland facility, and I will not change that one (also, I have a minimum contract length there).

Toom.im offers 76$/kW/m at the same 6 month contract lenght Thor DC (Advania, Iceland) offers. (Thor is 120$/kW/m though, and does not accept bitcoin or paypal payments).
Contracts with Toom.im are 90$/kW/m on a one-month term, with prices as low as 70$/kW/m.

I can say however, that I am moving an sp10 from spondoolies to Toom.im aswell.
Ambient temperature might be slightly lower in Iceland during the summer, but certainly not in the winter. While the sp10 is fairly temperature sensitive, sp30 isn´t.

Even if you had faster running ASIC, he will still makes it look dark.
I am not a customers of ST yet. I have admire their enginering skills from the beginning.
If you took the time to look closer how well designed the case is and easy to mass deploy a big
farm with SP 30 is, compared with all the other options out there.
Saying that their chip is bad with no proof except telling that you have some skills is hard to believe.

I don't blame TSMC (or GUC). The ASICs we got and getting are within TSMC acceptence criteria.
My hands are tied here. With one WAT graph I can prove my claims, but I won't.
You're welcome to email me privately. If you're not working for a competition, I'll disclose the info after signing mutual NDA.
It's much more than 10% increase and it's not post engineering.
I'm as transparent as I can be here. No damage control, but simple truth.
Even with the underperforming slow ASICs we have the best miner in the market.

Your expert opinion?

What specific degrees or experience do you have?

Why anonymously?

Not that I discount anything you are posting just trying to get a measure of your interest or bias potentially. There are people who have come on these forums to purposefully devalue brands so it be nice to know if this is intended as consumer protection versus narrative management for the purpose of degrading a company's image. The "truth" can be put in MANY different ways.

Can someone from spondoolies tell me whats going on with my hosted units? Order #1125

http://eligius.st/~wizkid057/newstats/userstats.php/1P19DeFn9dSkvv3d23y3BRJmmabTQiYHym

https://upload.robert-hager.at/uploads/static/eligius.PNG

 I am fine with this spikes as long as they level out, but it would be interesting what causes it? Especially would be interesting how three SP30 do 17 TH's ?  Grin

We're compensating you for a unit down time.
We'll replace your hosted unit with another units early next week, after production. One of your unit has issues.

With all due respect, I do have some doubts about that program which pushes PSU to the actual limit through repeated shutdowns.
Could it be the culprit? Perhaps, it is better to limit power to 1300 or even 1250W?
It is not worth a few extra GH if it significantly increases the PSU failure rate (for the purposes of argument- I don't know if this is true or not).
Not related at all to the PSUs
