any news when ants will be available again?
So while I love the S2, its just not as small apartment friendly as the S1s. I have one S2 in Raleigh, NC. Looking to get rid for equivalent price of Batch 2 ($3600 USD or btc) PM if interested.
So UPS should be delivering my S2s today... I am picking up a case of red bull just in case I will need to up all night setting up all of the miners one by one...
Thank you for everyone who had posted their solutions as I feel prepared for the long night ahead.

gig, there is much varience... my other S2 does not do this well..
also, this is early morning after a night of cool air.. later today I expect 1075 watts and a 4.88amp reading.

That would definitely explain it then. I'm getting 5.2 amps on 208v (1082w) in the data center.
Mr Teal: You can plug a killawatt directly into 220, it works.

Are the fans running with 1022w being pulled? If so, what speed?
Seems there is some pretty serious variance between machines.

Anyone managed to push theirs past 225?
Every time I 250, it jumps up to 1275W in, but beeps constantly and eventually drops back down in 5-10 seconds.
Edit: At 225M I get 1153GH/s using 1148W using an EVGA 1300W G2 on 115V. It will probably be a little better on 240V, but I don't have per-outlet metering on my PDU and I wanted to get power measurements using my KillAWatt.

To get it running @ +225Mhz I would suggest to up the voltage to 0.85V... Get out your pencil!!
Where's the rocket scientist when u need one?
check the overclocking thread. There will be two resistors associated with the output voltage of the TPS53355 regulator. using a pencil mod on one will increase voltage and pencil modding the other will decrease it. Figure out which one ups the voltage and go to town - 0.9V will probably unlock ~1.25TH/1350W. 0.95V might be sufficient for up to ~1.35TH/1.6kW if you can cool it a lot better then stock
I have a S1 on 0.86V and max clock is 250M (128GH), with 164W at the wall. 275M gives 138GH but over 10% HW error and 180W consumption.

After running all night, I'm now getting 1150GH/s with 1200W power draw, with the board 1 at 59C and the rest around 50C in a 25C room.

S2 owners,
heatsink mounts on the chip or back side of plate?

When. Will have roi at batch 2
Any news on a batch #3?
My guess is wednesday or thursday after the 10th deadline....news says this week

Anybody tried to oc it?
Mine will arrive on wednesday.....
Can the cards get more power throught the pci bus?
Did anybody checked the machine from this prespective?
Dc-dc, voltage regulatros, others?
I'm very curious....

Your is batch1 or batch2?
Just wondering if batch2 is out already
Im a batch 2 order, and if noone overclocks it first I might have to take the plunge. Should be lots of headroom in the components, but it may be necessary to use some sort of powered (with 12AWG wires) riser solution to get the boards up out of the case for better cooling
Mine is batch 1.
I wouldn't use risers, i think i'll make custom heatsinks and high cfm fans.
Heatsink will be this: http://www.fischerelektronik.de/web_fischer/en_GB/heatsinks/A09/Fin%20coolers/PR/KTE2_/index.xhtml;jsessionid=5F73345D9883E646BCDE77C3D3D5D73D
I can order it in custom sizes.
The fans will be high cfm sunons, i posted it already in this topic.
Server psu 2100w at 12v.
I'm only afraid of dc-dc, regulators and other components.
I'll do my best...
I have a server PSU im currently getting ready to handle lots of PCI connectors. I would love to see more photos of the PCB, since at least the TPS53355 regulators seem abundant enough that overclocking should not be a problem for them. The design is pretty simple other than that for a S1, so I imagine the S2 is similar which means OC/OV should be the exact same methods but very successful.
Those heatsinks would be a lot better - if you get them made let me know
I would suggest not having too many fins, because the S1 heatsink is a jagged dust-trap because of how many fins it hasI will be more clever on wednesday...
I was thinking about the pci slots, i did't saw on the pictures but as i seen the cards are sucking the power throught the pci slots. But if they get it throught pci-e power connectors for every card that would be the best...
If they suck throught the pci slots i'm a bit afraid the layers and the connections of the pcb too, if you give them too much power.I'll drop a picture with the custom heatsinks as soon as i get them, but first i have to measure the sizes, then order them, then make the holes for the cards.... Some fine works.
A lot fins are fine, just use as powerful fan as you can so there is no chance of the dust to stay there
. But of course if I can get a lot of more hash from the machine i will clean it with a big smile on my face every month.
