BITMAIN Antminer S3 support and OverClocking thread

[Master One]

Is there any custome, app ,tweak,homebrew, jailbreak,firmware modification or Special update for the S3 , a Must have or i'm fine with normal antminer S3 Support ?

Not that I'm aware of, but every S3 owner should be waiting for the firmware update featuring ckolivas' latest cgminer version.

Tell me more about that mind blowing thing

I don't own any Antminers yet, but I can tell you that there are no real tweaks to be made to make a S3 better, it simply is the hardware that does the real job. The thing with the outdated cgminer version Bitmaintech has been using is mentioned somewhere here or in the other thread, and they just recently released their patched version (which they were obliged from the beginning due to the GPL), so hopefully something is happening concerning that matter. The newer cgminer will not give better performance but a security bug fix afaik.

patch is the word i forgot
Umm ok thanks a lot for the Information

Fair enough, but it's my understanding that modern network adaptors carry out the crossover function automatically.  However, I'm not sure that all of these adaptors will autosense if a crossover cable is subsequently connected.

Yes, it's called Auto MDI-X and as long as at least one side of the link has the capability, it doesn't matter whether you have a crossover cable or a straight-through cable, the interface will sense it and act accordingly. The speed and duplex need to be Auto.

Did you get your router? If so, go to the command prompt and type in ipconfig and get your default gateway and report back.

Hello again.

I just received another S3 and have some questions. First off, how can I tell what batch this S3 is? I already have a Batch 6. I have provided a screenshot below. Please take a look and see what you think. I dont have it OCed. I do have the latest firmware on it. I am having issues with the HW errors. Are these specs too high? Should I b concerned? I have thought about taking it apart and applying new thermal paste. Think that might help?

Thanx again .

You're at a 1.2% HW error rate right now. But everything else looks fine. Looks like it may be a batch 1, especially if you bought it from a third party used.

The only way that I know of how to tell what batch it is is either buying it yourself from bitmain or asking the person who bought it.

Yep, you ARE having an issue there with the HW errors. Too high for an S3 (and one running at stock frequency at that)!
1. Are you sure you are powering it up adequately? If that, do a power recycle (there may have been a power spike since you turned it on) and see if the errors settle.
2. I have noticed that the HW errors general % varies from pool to pool. I did not think this to be a contributing factor, but I have observed on my S3's that it may indeed be a factor, thus, try hashing on another pool for several hours. That being said, your error rate is far higher than what I'd attribute to a pool.

HW/(HW+DiffA+DiffR)=HW%

[pekatete]

HW/(HW+DiffA+DiffR)=HW%

I've always wanted to clarify this, so here goes.
What exactly does DiffR represent? I assumed this represented the number of rejected shares at the current Diff, but its rate of increase seems to be (at times) the size of the rejected share. If that, would that not throw the calculation off?

Here's what I found:

--------------------------------------
Diff1 = The number of  Difficulty 1 shares generated
DiffA = The number of Diff1 shares accepted
DiffR = The number of Diff1 shares rejected
LSD = Last Share Difficulty
Discarded = stale shares that cgminer knew were stale so it didn't even send them back to the pool
---------------------------------------

It is strange how the DiffR number differs widely (in shape and size) depending on which pool you mine at and which hardware you deploy.
The S3 for example does not show a best share on some pools whereas the S1 does, in the same breath, the S3 increments DiffR in multiples of 32 on some pools (in the case of ghash DiffR equates to stales) whereas I'd have expected it to be singulars as is on slush.

Which leads me to believe that some stats on the S3 are massaged thus the HW error percentage is ..... who knows!?

[windpath]

It may be worth noting that while not often reported, DiffS (Stales) should also be included...

HWE% = HW / (HW + DiffA + DiffR + DiffS) * 100

HW / (HW + DiffA + DiffR + DiffS) = HWE%

Don't forget to X 100

Hi,
I just try to update S320140811 with frequency management.
The frequency 225 is not part of the option (I do not know why?), it goes directly from 218.75 to 237,5.
Can someone tell me which file to edit to add the 225 frequency in choice?
THX.

The file with frequency values for the advanced page with miner settings is

Code:

/usr/lib/lua/luci/model/cbi/cgminer/cgminer.lua

Look at the end of the file for the frequency list.

Here are highlighted in red the lines with new frequency not included in the stock firmware.

Suggest this be added to the OP to help anyone running newer firmware who wants more OC options from the interface.  Thanks JakeTri!
