Anyone get shipping notifications yet for orders placed on Monday?

I spoke too soon, scheduled for Friday delivery. Knowing the way UPS works in Winnipeg hopefully I will get it by Tuesday.

My Sunday order will be delivered to me tomorrow, my Monday order will be delivered to me on Friday.
Both confirmed by UPS as they called me to tell me to have the customs fees ready.

 

Yup..sunday order coming today, monday order coming tomorrow..sweet..more hashrate - addict to it..happy to see over 1th..

if you need PSU, don't look Watt only.
please check Ampere in 12V.
Minimum requirement Ampere in 12 V is 30 A

This is a good point.  I recommend Corsair power supplies - at least 750 watt models or higher.  The CX750M is a modular design so you'll have less cable clutter and it supplies 46 Amps on the +12V rail.  Whichever power supply you're using, look at the +12V DC Output amperage and ensure that it's greater than 30 Amps.

Even something like this will work but I like the CX750 better

that is an 80+ bronze. is not a good recomendation for psu because of it's effiency of 80% .. can do better and buy 92% effiecient psu's like rm1000 can host two oced ants.. i saw someone post an 80+ bronnze psu was pulling 400 watts per non oced ant . should choose 92% efficient psu to mine with imo . choice of psu is most important for longterm mining considerations.

There is no customs fee for the US, right?

It didn't come up on the one I purchased. We also have no VAT/etc to worry about in US.

Its not just the UK, nearly all of Europe has VAT: http://en.wikipedia.org/wiki/Tax_rates_of_Europe

According to bitcoinwisdom.com calculator, the antminer s1's ROI in about 90 days.

Is this about correct? More? Less?

Why hasn't there been a price reduction today?

[CroverNo]

Why hasn't there been a price reduction today?

Not sure... was expecting a good drop as BTC price has jumped 25$ from what yesterday price was set at.

Wow. I know its coming some day to the US given the worsening debt and fiscal situation but at least not today

Have you guys looked at what the actual power savings are in comparison to the added cost of a >bronze supply?  For almost every attempt I've made to justify higher efficiency supplies the savings just never make it worth while.

That is my estimate too however alot depends on the difficulty rate increases. Today it is expected to only go up 11%. Sometimes it jumps 20%, a few times it jumped way up even more. However based on an average of 20% increase every 11-12 days you should make about 1.3-1.4 BTC in 90 days or so. I think my math is close.

[axpguy]

Has anyone had them ship to Canada before? If so how long did it take?

Ordered 3/07
shipped 3/10
Arriving today 3/12

I am in Toronto near the airport.

plus about $200 in power costs for that timeframe

Corsair AX1200 works good for 2 and EVGA 1300G2 works perfectly with 3. OC'd these draw 400 watts.

Great! Thanks!

Another option is to underclock and run 4 off a single PSU.

Run the math: you may find that it makes more economical sense to save $100-$200 on additional PSUs, rather than getting an extra 10-15% hashrate by overclocking. Everyone's situation is different.

I run 4@325MHz on an EVGA 1300G2, and another 4@325MHz on a Seasonic X-1250. These combinations use ~1400W at the wall (@120V) as measured with a Kill-A-Watt meter, which is fine for those PSUs and is within the continuous rated limit (80% of 15A/120V: 12A or 1440W) of a single 15A/120V household circuit.

Some other combinations I run: 2@350MHz (stock) on a Corsair HX750, 2@350MHz on a Corsair AX760, and 2@375MHz (overclocked) on a spare Seasonic X-1250 (which is overkill for 2 Ants).

Wow thats expensive power you have, mine is less than half of that for 3 months.

I think the power costs will be much less than that.
400 watts x 24 hrs day /1000 = 9.6 KWH a day times $.10 x 90 days=$86.40

How much hash do you get running at the three clock speeds plus temperatures? Its still winters, so heating not an issue but apartment already feeling like an oven

Assuming no dead chips, you can expect roughly:

325MHz: 167 GH/s
350MHz: 179 GH/s
375MHz: 192 GH/s

These numbers will vary a bit across hardware and firmware revisions. In other words, YMMV. The difference in reported temperatures between the 3 speed levels is minimal from what I have seen; perhaps 1 degree at most. But since 325MHz Ants generate 45W less heat than 375MHz Ants, the fans on the underclocked Ants run slower (and quieter).

that is an 80+ bronze. is not a good recomendation for psu because of it's effiency of 80% .. can do better and buy 92% effiecient psu's like rm1000 can host two oced ants.. i saw someone post an 80+ bronnze psu was pulling 400 watts per non oced ant . should choose 92% efficient psu to mine with imo . choice of psu is most important for longterm mining considerations.

agreed

well lets see if i can calculate non-oced ants.. the difference is about 50 watts per ant between 80% efficiency (aprx 400 watts) from 92% efficiency (aprx 350 watts) from earlier screenshot of an 80% efficient psu in this thread:

(second post down screenshot 80% bronze psu ants running @400 watts each) https://bitcointalk.org/index.php?topic=417159.2460

two ants per psu equals around 100 watts saved. that is about $10 - $12 per month per every two ants @.10kw ?? cx750 psu @$90.00 per ant (newegg) initial cost while rm1000 is @$100 per ant initial (newegg). in addition can oc two ants on rm1000 .
