We are pleased to launch the Antminer S9 Limited Edition with a hashrate of 12.93 TH/s. It is ready to ship immediately upon order confirmation. Antminer S9 is the world's first bitcoin miner based on the 16nm process node ASIC chips.
I'm sorry, does that mean that everyone who bough a S9-B2 will have to wait until 20th June to get their orders shipped, but those who order now from the third batch will get their orders immediately shipped?
Here is how I have moved my fans, their are strapped with zip lock to the PCIe cables, temperature dropped with almost 20 degrees, now running under 40 degrees overclocked to 211, getting 485 GH/s. 231 and 251 are not working very good for my miner
Based on these images I am not sure if adding heatsinks to VRMs be really beneficial. There is a danger of reducing the air flow in areas really needs cooling.
Does anyone know where is the temperature sensor for the ASICs?

What temps do you get on the chip itself? From the web interface and from your readings? And what hash rate do you get per board? If there is a better way to cool the down side of the VRMs, we'd be able to achieve better performance, any ideas?

not sure on those temp readings.. I saw without the shroud you get less drop and tilting down kept more heat on the boards
are you 20 degrees less than stock config?
you might also be pointing directly onto the temp sensor. I forget where that is but if it is working for you don't move it !
It is minus 20 degree from overclocked, before my temps were around 57-60 now there are 37 to 40, both times with the same config 211. now the whole box feels cooler, the vrms are cooler, and the whole radiator is cooler, I think the readings are real.

I have a problem to solve. Maybe some of you are experiencing this, too:
My OC'd Saturn machine is hashing at a much higher rate than BTCGuild is reporting. I tried resetting the worker to clear stats, but it's still reporting as much lower than the machine itself is reporting.
MORE DETAILS: ----------
I succeeded at least in overclocking on paper and have been running overnight. There are still at least several things I'm unclear on, such as how to get wizkid's cgminer in place, but those will come in a bit, I guess.
Does anyone know why my Saturn is reporting a significantly lower hashrate than at BTC? The Saturn GUI is reporting 326ghs, but poolside BTCGuild hasn't budged above 292. That's quite a difference and not markedly better from my un-OC'd machine.
I tried resetting my worker stats, but that doesn't seem to have done anything either. BTCGuild is reporting 0.13% rejects.
My machine: October version Saturn Running 99.1-tuning OC'd to 231
In SSH as of this moment, the Saturn is showing 329.3G/325.8Gh/s. Still a long way off from 292.
Does anyone know what this issue might be?
My october mercury with 2 added modules(total 3) runs way better with 211 - around 485 GH/s, with 231 there are a lot of disabled cores and is hashing with no more than 300 GH/s. Try 211 for some time.
