I'm not sure what the upgrade is... But I've heard firmware, just can't remember where... If that's the case it wouldn't be replacing anyting in the old unit.

Although - Increasing its hashing by .8 - 1.0 TH with simply firmware seems a bit of a stretch. So, I don't know.

Guess we'll just have to wait for another announcement! I'm sure now that the S3 released their R&D team will be focused on the project.

BM said they would be providing upgrade hardware for the S1/S2 owners in the announcement OP of the S3. Not firmware.

Yea, been tracking this but nothing since mid Junish... Last word was August/Sept timeframe.

Late september would be fine with me… I can't picture any S2 owner wanting to upgrade right now because not even the batch 1 units have been in the game long enough to ROI… So with that said you would be throwing away money unless there was a way to use the old cards .. It would be nice to see if someone could come up with a Pi mod or BBB mod to use the old boards.

I'll happily replace a couple board to put less stress on the PSU, though. If we could hash last-gen/next-gen in the same box, that would be grand. That may be a pipe dream.

Is there a similar form factor s4 coming soon? Really wanted to finish off this server rack with something similar to the s2, but using 28nm chips of course

No word yet. Upgrade boards for the S2 were mentioned in an OP from BM, but no word yet. I would presume those boards and an S4 product would release pretty close to the same time, as they may be the same cards!

A humble Siberian miner

Today I have received my AntMiner S2. Nice package, nice device, nice smell, seems to be working well for 8+ hours...

I did not performed a firmware upgrade because of non-guaranteed power (it's Russia...), I will do it later, when I'll place it to the place of free electricity... Wink

Now my miner is:

Code:

Kernel Version Linux 3.8.13 #1 SMP Fri Jan 17 23:04:23 CST 2014
File System Version Thu Apr 10 19:08:42 CST 2014
Cgminer Version 3.12.0

They are generally good to work with. Just need to be specific on what you need and what is going on. The more concise detail you give them the better.

I have bought 19 miners from Bitmain.

However I have spent the last week plus now trying to get a location they want ONE of the miners to be returned to as it has NEVER worked. They asked me to check all the boards, do my best to work through the problems.

The problems are
out of 10 hash boards in the S2 ALL are damaged or warped badly.
There are diodes missing on 7 of the 10 boards.
The boards do not line up with the slots in the case.
The miner has never worked today they ask me for screen shots.
The miner has never worked how am I to get them screen shots.
I have already take a miner off line, to test the boards.(I had a 80 mile drive to do that)
They are warped so bad that they do not fit properly into the slots on my other miners.
Also VERY slow response to the emails. took 4 days to get my first response.

Anyone else having the same problem with Bitmain

Interesting S2 behavior on 6/19 version of system software: a "Lazarus" function is active.

Before with my previous S2 once it shut down, it stayed shut down until I power cycle it.

with the last batch version I noticed something different. It does shut down on average once in 3-4 days, goes all the way to zero hash for a minute or two, then mysteriously springs back to life automatically. I think that they changed something in software to restore it to "life" automatically (at least my machine behaves like this). This is quite cool if true. Next time your recent S2 miner starts beeping and shows zero hash, don't restart immediately-give it 5 min and see what happens.
I am going to double post this in S2 setup thread in case this thread disappear.

Waiting for antminer s2 to drop the price further, price is still too expensive compare to S3.

what is your dB reading currently at 1m distance? I have one fan at slow rpm blowing into the miner, nothing to suck air out and it is at 62-63dB, which is quiet.

I don't know if this sound meter app is accurate but it says 69db. I took 4x 120mm silents out of my BFLs and popped them ontop to test the theory out. So currently I've got the 4x 87CFM fans blowing air into the antminer from the sides. Then 4x 55CFM fans sucking the hot hair out and blowing it upwards. It looks like the temps have dropped to 55c except for 1 card which is at 59c (probaby the one on the end not getting much coverage by the 120mm fan). So I would venture to guess 4x more 87CFM fans should do the trick as I think I read ~56-57c was the standard temperature with stock fans.

I'm trying to convert my antminer s2 so that it is mostly silent. I've already purchased 4 new silent fans (http://www.newegg.com/Product/Product.aspx?Item=N82E16835242011) and installed them however the CFM just isn't good enough and the antminer temp is getting up to 71c. My next plan is to buy 4 more 140mm fans to place on top of the boards with the case off. I'm thinking another 4 of the same or maybe upgrading a tad and getting (http://www.frozencpu.com/products/13819/fan-901/Akasa_140mm_x_25mm_VIPER_PWM_Fan_w_Hydro_Dynamic_Bearings_AK-FN063.html?tl=g36c435s1104&id=kepe2EsK#blank) Do you think 25dba is going to be too loud or should I stick with the 18dba 87CFM fans?

Second question is going to be fan direction/placement for optimal airflow. Should I configure it so the 4 side fans all blow air into the antminer and the 4 on top to suck air out and blow it upwards. Or should I use the 4 ontop to blow air down into the antminer and the 4 on the sides to suck the hot air out?
