Same with travel credit cards, prepaid, you put money on it, no credit line, good anywhere mastercard (or visa whatever) is accepted.

Except when trying to rent a car.  Don't get stuck in that trap

I still have 8 hours, wtf??

they probably are basing expiration on local time in china.

Hello all, I am new here and want to say hello.

I have a few questions. I received my Antminer S3 Batch 6 about a week ago. Today I upgraded the firmware to the latest firmware that was on bitmains website.

Prior to upgrading to the latest firmware, I could use putty to log into it and edit the config file to OC it to freq 225 from 218.75. It raised the hash rate but I was getting some HW errors so I put it back to 218.75 and no more HW errors. Well, after upgrading to the latest firmware, I decided to OC it a bit to see how it performs. First I set it to 225 using Putty. I then rebooted the miner and it appears that it is still operating at the stock frequency. I tried some other frequencies and all give me the same results. The frequency according to the web gui on the antminer still shows the stock frequency.

Prior to updating the firmware, if I changed the frequency, it was shown on the Antminer status page, the new frequency. Now with the new firmware, it stays at 218.75 on the status page. No matter what frequency I choose using putty. I included a screenshot of the miners status page. I have it set at the stock speed. With the old firmware I had 0 HW errors no matter how long it ran at stock speed. Now with the new firmware, I have HW errors(though not many) and I can nolonger Overclock. Is this normal.

My screenshot is showing a nice hash rate but it isn't consistently this high. It fluctuates greatly.

I am also curious what a few things on the status page means? Such as:Diff. DiffA#, DiffR#, DiffS#, LSDiff, LSTime?

I am using a Rosewill Lightning 1300 PSU. I have 4 separate PCIe 6 pin connectors connected. Is this PSU a good PSU for mining? I am hoping to connect an S1 and a S3+ also to this PSU. Think that will be too much for this PSU?

Sorry for all these questions. I am a newbie trying to learn this all at once. The more I read the more overwhelmed I feel.

Thanx in advance for any responses. Sorry if these questions have already been answered.

They changed the way that you change the frequency in the latest firmware. Instead of modifying the asic-freq file (which it appears to ignore now) you now instead make the changes via the 'Advanced Settings' tab in the 'Miner Configuration' area of the console.

Thank u for your reply. I feel stupid. I read about the Advanced Tab but was over looking it earlier.

Used the Advanced Tab and set the Freq to 250M. The Hash Rate raised a great deal though it does fluctuate a good bit. Should I be worried with the HW rate? What is considered too high of a HW?

Talking about cgminer redirects, does anyone know who unknown.servercentral.net comes from? My S3 seems to be connected to it. Can't place it to any of the pools I use (slush and btcguild).

  look like DNS thing

50.31.189.49
unknown.servercentral.net
IP Address Information
The Internet Service Provider (ISP) that owns the network address of 50.31.189.49 is Server Central Network and located in Illinois within the United States. The IP Address resolves to the DNS record of unknown.servercentral.net.
Network Communications


The following file have been seen to comunicate with this IP address in live environments.

TCP port 3333
cgminer.exe

 



I looked up that information too, which does not really give me any clue as to which pool it belongs. It connects on port 3333 so it really seems to be something to do with mining.

that ip address wasnt pool but ip is for DNS.

Odd that it's using that port though, DNS is usually TCP port 53.

[squashpile]

That is suspicious on 3333. How did you notice this? I'm going to cap a bit with Wireshark. Is your pool on 3333? I'm guessing it's not or you would not have mentioned this. It would be very unusual for DNS traffic on that port as mjk mentioned. It's probably nothing.

I have a question about the stratum difficulty.  I have two Antminer S3s, and I'm using the GHash.IO mining pool.  Their FAQ says:

The optimal settings of the stratum difficulty depends on your hash-rate:
16+ GH/s - 16 difficulty
32+ Gh/s - 32 difficulty
64+ GH/s - 64 difficulty
128+ GH/s - 128 difficulty
256+ GH/s - 256 difficulty
512+ GH/s - 512 difficulty
1 TH/s - 1024 difficulty

So based on that, the setting would be 256 for each miner.  Does anyone actually alter this setting in their mining pool?  Or do you just keep the default setting?

thank you.

I don't think it's for each miner (unless you have them as different workers). If they're set as one worker, then set it to 512 (or 1TH if you can get it stable over 1000 GH/s). If they're separate workers then yea, 256 should be fine.

But Yes it works in every pool I've tried (4 or 5 different pools)

They are set up with different worker IDs.  I thought that was required.  I didn't know I could have two miners in the same pool with the same worker ID.  Does that work?  Is there an advantage to doing that?

No... It's hard to see/track your individual S3's performance...

I'm using separate workers for each of mine S3's ...256 diff...

ZiG

But Yes it works in every pool I've tried (4 or 5 different pools)

Stratum difficulty can be "forced" on some pools (Ghash for instance) on others it typically is calculated and/or set by the pool (Eligius).
This is normally set on an even bit boundry (16, 32, 64, 128, etc. . . .)
We are currently hashing on a pool that calculates, over time, a precise difficulty for each worker that does not necessarily fall on an even bit boundry.
We are seeing Stratum difficulty raging from 281.07 to 454.57 on our 12 S1's and 796.60 to 1084.24 on our 12 S3's.
We see, when implementing a new miner, this pool defaults to 512 and adjusts that value over time.

I think I'm seeing less stale, Dup, and low difficulty rejects as a result.
But am reticent to make a definitive statement as too the observation.

Does this makes sense, Oh Great and Knowledgeable Stratum Guru's?

Thank you Spondoolies Tech BITMAIN for helping me earn more BTC/day today than I did 11 months ago despite the huge difficulty difference!

1% or less for hw is fine

HW/DiffA+Diffr+HW

for you 13/544,562+ 1665+13 = way less then 1%

If you place an order at Bitmaintech, when do you have to pay?

[grn]

If you place an order at Bitmaintech, when do you have to pay?

pay immediately, they expect the transaction to clear within 1 hour. sometimes it takes longer and your order will show as invalid but they fix that within a day.

[tarmi]

anyone got some coupons for sale?

[Master One]

anyone got some coupons for sale?

Or just to give away for free, after all there is no point if not using them yourself anyway and just letting them expire...

yes, I wouldnt mind getting one for free.

[Master One]

So if anyone here has one or more coupons available and would be so generous to give them away for free, please send me a PM!

Looks like begging, but what the heck, if you let them expire you are gifting their value to Bitmaintech, as if they would need it more than a fellow forum comrade. I at least would be thankful!

[sirux]

As a first time antminer buyer.. i'd love a coupon!

Just run netstat from the ssh console. It shows you all current connections. I have actually figured out it is related to the btcguild pool, if I drop packets going to the networkcentral range the btcguild pool starts showing up as dead. I can't really figure out how it is related, because none of the btcguild addresses I find seem to be anywhere near that range.

[skizzneena]

Are there any S3's left for sale anywhere?
