ANTMINER S3+ Discussion and Support Thread

[Xian01]

I just flashed a B5 to the newest firmware, defaulted to 237 instead of 218.75, and at 237 I was getting really bad hash-rate at ~100GHs Had to set it to the default 218.75 to get her back at ~440GHs.

Was sad to see 225 was not listed in the frequency drop-down.

There are 262 pages not easy to read them all.

My S3 will be in my hands tomorrow. What I would like to learn is whether I can use a Butterfly labs 50GH/s Power Supply on Antminer S3 ?
I have already bought a 600W PSU with two 6 pin cables because I'm not going to overclock.
But if Butterfly labs PSU works with S3 I will give the new one back.

If anybody can give an idea I appreciate...

Please do not use BFL Single SC power supply units to power your S3s or any device for that matter.  There's a good reason why a whole lot of BFL preorder victims (including me) refrained from using them and opted to use ATX PSUs instead.  The workmanship and the quality of their components are substandard to say the least.  They're known to produce some spectacular fireworks.  Hopefully, the following videos would dissuade you from proceeding with your plan:

I though I saw it but your right, it's not there. Curious as to why though when 225 is supposed to be default to the S3+ or w/e.

Curious if this new FW will even be on the S3+. No that it matters since at the current price point and projected release date and the diff increases between now and then it could easily be a wash.

still have coupons. what to do with it?

Make a gift to someone until they are still valid...

yea, at least you will make them save 0.075BTC.
not that they will mine a lot more when they'll ship in september.

I am curious has anyone had any RMA issues with Bitmain ?  i have provided them with the order ID and I am still having the hardest time getting RMA information from them.  They have demanded I perform a test with something called a multimeter (which i do not own, i had to go purchase one)  so i could test the chains.  My s3 device pretty much bricked itself with a firmware upgrade.  I cannot access the UI, the ip is not found (never changed from default).  I used an ipsniffer, and still zilch....anyhow, i am curious to know how Bitmain has dealt with RMA requests from others.   Thanks

Whew!  This afternoon is one of the hottest if not the hottest period for my S3s which have been hashing at 225M for the last 40 hours with the following data:

Tambient = 36C (97F)
Tdevice = 46C
Wattage at the wall = 380W
Hash Rate = 453 GH/s
HW = 0.015%

[MoreBloodWine]

Does anyone know of a way to "hack" the S3 so instead of say showing an HW value of 200 it takes that and the diff's, does the math and instead displays the HW % out to like x.xxx ?

It took me 2 1/2 weeks of those emails back and fourth. I finally told them I would sell it for parts on Bitcointalk.org and tell everyone about them not honoring warranty. Then and only then did they sent a RMA form. I sent it(controller) off 3 weeks ago and still don't have a replacement. Good luck.

anyone buying S3+? still have 2 coupons. Just buy me a beer. =)

It would seem to be a safe statement to say that the S3's do not hold up to the quality shown and expected from the S1's and S2's.

Sad.

And unnecessary. And expensive for us, the customer.

Their reputation is taking many hits and they're not all good. It's the result of someone's active decisions and they weren't good for the short term and certainly not for the long term.

I would strongly suggest not upgrading to the newest firmware!
(antMiner_S320140811.bin)

Effect on hashrate as reported at pool - 30 mins:



Miner dashboard - 30 minutes:



It changed the frequency to 237.5 according to the new advanced settings tab under miner configuration, but it does not show any frequency on miner stats page (above).

Best speed seen since upgrade: 119.27GH/s

Average speed prior to upgrade: 447.82GH/s (@Freq 225, surprisingly not an option under advanced settings)

That happened to me too, after the firmware upgrade it automatically changed me from stock 218.75 to 237.5 and the hashrate went down to 100 Gh/s with the frequency not showing up in the console. If you change it to 218.75M or 250M in Advanced Configuration, however, it goes back to mining at rates you'd expect at those frequencies. For whatever reason the upgrade switches it to 237.5 and it simply doesn't work.

Interestingly enough, if I SSH into the box, the asic-freq file shows me running at a different rate than the Advanced Settings tab and the status page show. Whatever they did in the firmware upgrade apparently bypasses the asic-freq file to make the changes. In any case, I have my four 'well-behaved' miners running at 250W now, and the two trouble children that don't OC well running at 218.75 on the new firmware and all seems fine for now. But agreed, the firmware update didn't seem to help much and makes me a bit nervous now.

[Xian01]

/etc/config/asic-freq appears to be completely irrelevant in this latest firmware

Appears to have moved to the last line in /etc/config/cgminer

option freq '18:218.75:1106'

EDIT: 225 is a bust for me on this B5 unit. Hashes @ ~350-400GHs. 218.75 is the magic number it seems for stability @ ~441GHs.

I've had horrible luck with the S3's The S1's I had, the the current S2's I'm running were/are rock solid comparatively. Across a dozen S3's, nearly 40% of them are underperforming requiring underclocking, and Bitmain has not been responsive on a compensation/resolution for underperforming units

Fuck

EDIT2: Reverted to prior firmware. Something doesn't seem right with this latest one. Performance appears to suffer based on the short testing I have done so far on a B5 unit.

What were your failure symptoms? I had one die today.. going to have to go down this road...

[windpath]

After fiddling around with it, I'll have to retract my previous statement and I'm happy to report better then previous performance with the new firmware (so far), it happened on this particular miner at a freq of 237.5, available in the new frequency drop-down.

Ant # 92:
Rate before upgrade at 237.5 = 441.73 (average over 3 days)
Rate after upgrade at 237.5 = 454.90 (30 mins)

Man these are finicky...

Has anyone else with a Batch 8 order lose their edit option?
Seems a little too soon for that to happen.

It may be a way of protecting your purchase at the current price. With the HUGE drop in BTC value the last couple of days It's possible they may have closed editing and will raise the btc price very soon to reflect the current exchange rate.

Sounds reasonable enough. Because the BTC price drop was the reason I pulled the trigger and placed the order. Thanks.

Thank you visdude,
I will not use BFL power supply with S3, in an emergency may be I can use but very short time and keeping an eye on it.
I will not use with the new S3
