Hey, I just got a S2 yesterday, it had a lot of HW errors so I updated the firmware and cgminer to 4.6.1 it fixed the HW problem but now it only hashes at half capacity!!

Has anyone experienced this or know a solution.. I really need help - I have little experience with this.
Oh, and I work from a Mac or Raspberry Pi if that helps.

FIXED!!: Hey, so using the firmware, it's system>upgrade>perform reset and the whole thing started back good as new.. maybe make a backup before you do this if your nervous.

Alright, now I am getting a consistent 1015.7 gh/s.. I've included the system backup, I've made.. It should get you to antminer firmware dated October 28 2014 and cgminer 4.6.1 - the highest you can set the asic-freq is 200, but it works like a dream. To use it go to: system>upgrade>restore backup .. Thanks!!!

Thanx! I'll try it after weekend.  Cheesy

Well, I have just upgraded my S2 with this new FW (paycoin fever...). -100 Gh to hashing speed even with 200 on "advanced" tab... Will try to OC later.

p.s. found now that OCing of S2 with this new FW is not so obvious task... Please someone share how to do that...  Huh

Thank you for your reconsideration of the matter.

Unfortunately you seem to have overlooked the three (3) blades that were also part of the same issue. Valued by BITMAIN  China at 100USD each.

Also, if we had closed the matter in June as agreed, then the June BTC value would indeed be acceptable.

Instead you opted to cause us all much frustration & financial burden up until now, where the BTC value is less than half of what it was when you could/should have ended the matter.

As such i implore you to re-calculate the full refund value of 260 + 230 + 100 + 100 + 100 = 790 USD in todays BTC price.

This will be wholly acceptable & i will agree that the matter is indeed closed. I will also post my appreciation on each thread to remove the aforementioned tarnish.

I am regretful it has taken so long and so many posts to finally come close to a reconciliation, but i welcome the opportunity.

Sincerely,

Edgar

Who said that I'm on stock PSU? It has been replaced with Corsair AX1200i long ago... And S2 was running at 1.1 Th (at Slush's side) on Kano's firmware.

So my current PSU should be enough for overclocking, please share the appropriate methoda how to do it with newest official firmware.  Roll Eyes

the kill-a-watt I have is showing at 1115 Watts at the wall.  Since just moving the box it has been shutting off quickly.  The only other thing that I have done is update the firmware a while back and have it set at 196M and 725 Volts.  I have a 18 gauge computer cable that showed some wear on one of the terminals.  I ordered a 14 gauge cable to replace it.  There's some dust inside, but other than that I'm not sure what is going on.  Anyone have this problem.  I'm close to retiring it anyway, but would still like to know if it works fine (and safe) until I shut it off completely.

What voltage and frequency were you running before? If you're getting 1115W at the wall then you're very close to maxing the PSU. (as are stock S2s though).

It's always been stock frequency and voltage.  So I'm not really sure why its doing that.  In addition, the watts start out at 1090 and then increase after thirty minutes to 1132.  After this at some point it shuts off.  I'm not an expert on electronics, but could this be something that would be caused by one, the 18 gauge power cable?  Or dust in the S2?  Or do you think it is the update I made to the firmware?

I'd feel around the new outlet, see what it may be sharing the circuit with, you said you recently moved it, may not be playing nice with something else on the line or a hot panel breaker.

The things you've suggested as causes are all reasonable, although you can probably ignore firmware for hard shutdowns. It will either be PSU load, PSU overheating or your cable overheating in some fashion.

Did you replace the cable before you moved the box? Was it working fine with the new cable before you moved it? I'd suggest trying the old cable for an hour to eliminate that possibility.

If you see dust in the miner then there is probably more in there than you think, I'd suggest taking the boards out and cleaning them off with a damp cloth. You'll be surprised how dirty they get and what a difference it makes to the fan speed after a decent cleaning.
