Lot of errors



Can't see any of your images. But I imagine that miner is broken, could sell it and try some s3's.

My S2 was working fine for a week in eligius, after a payment delay decide to try Ghash, coincidence or not the HW errors went to sky, any suggestion?

I figured it out. Put in on btcguild and see what happens.

sick of a B4 rig that wont stop dwindling down to 8xx i started pulling cards out and checking the thermal paste.

so far 4 out of 4 have been absolutely terrible.

right now with those 4 redone, i am seeing 11xx instead of 8xx

i did not restart or reboot, just pulled the blade, did the job, stuck it back in.

i will continue doing the remaining 6 when i have some time but thought some of you might appreciate a heads up.

Also, while only running 9 blades i saw 980GH/s pretty stable (about 20 minutes to remove, cool, brush, unscrew, reapply etc)



Are you serious - popping boards in and out of a running system doesn't make the whole thing blow up?  sounds very risky, no?

Placed an order of 6x S2 Antminers on 2014-06-16 and received 5 of them, but after more than 45 days one of them is never received!!!

All sent by EMS, I contacted local EMS and claimed for the shipment and contacted Bitmain to check with their local EMS several times but absolutely no results yet!

This is the EMS tracking number results after so long time:



I don't know what should I do!!!! Huh Angry

A short good news for the S2 buyer is that we will let the S2 to upgrade to 1.8TH/s or 2TH/s at very low cost which you can only image now in the August or September.
Could you please tell us will this upgrade require PSU replacement with more powerful unit? If so, what will be your recommendation about PSU power?

Bitmain,  any updates on the S2 upgrade option as discussed? A lot of us have paid a high amount of BTC/GHs for these, (at least I) with the understanding we will have options to increase hashing power very soon.

Right now the S3 is their priority ... as their online advert says "The S3 is selling like hot cakes". They are making big time right now on just one product.

I'm sure they will at some time bring S2 updates out, but I wonder if you would make ROI after including the initial purchase price ... and maybe you would need to purchase a better PSU to raise an S2 to 2TH/s+ ??. The S4 (or whatever it gets called) might be interesting, but I've decided to sell my S2's and wait. Somehow it feels safer, hopefully keeping ahead of the difficulty curve.

My trouble machine has be running at about 950 for a week, so I'm afraid to pull it out and reapply paste.  Let us know the long term effect and I'll do it, though.

And with Kano firmware will hit 3 th?

No, that's an erroneous reading.  The S2 cannot hit 3TH.

One of my boards has 16 bad chips. Does anyone know if this is replaceable or is it still within standards? I tried e-mailing [email protected] last week but never got a response. I never get the full 1 Th/s I'm usually at 970 Gh/s then it will creep down to 930 Gh/s.

The weird thing is that when I do a full power off and turn the s2 back on it will show all chips working for 12-24 hours then the first 16 chips on the board turn to x's as seen here:

I've seen a few other people in other threads who experienced the same problem but I don't see any posts about resolving the issue. I've tried swapping the bad board into a different slot as well as pressing all the chips on the board. So it's not a problem with the slot and is definitely something wrong with that board.

Probably a failing DC/DC regulator.  Pull that board from your machine and overclock the rest of the boards until you're back at 1TH.

Dunno, can we trust you?
We can do escrow or Paypal, I'm happy with either.

If he said yes - would you - treat bitcoin like cash

[edit] I probably would with a small amount btw
