Can anyone help me setting up my antminers.
Just received supposedly 2 x U2, but they are hashing at 1.6Gh/s on the bitminter client.
How do I overclock them to at least 2Gh/s ?!
It's written everywhere that there are easy to overclock but nothing on HOW !!!

Thanks for your help.

Click green arrow on Antminer to expand its display in the client, then click the wrench that appears.

[Jayjay04]

oh wow !!! didn't even know about that !!!

But they are not working anymore...

2014.03.19 [10:54]  Icarus (COM9) ERROR: Selftest error. Expected nonce 0xFFFFFEFE but got 0xFFFFFE0E.
?!?!?

[Jayjay04]

Oh I had to do a little of reopening the client and make it first run at 1,6 then I am able to overclock it to 2,2.
But there is one that do not want to work at 2,2 but at 2,1 yes.

Might it be my usb port that doesn't receive enough power ?
Because I have 3 block erupters and 2 antminers directly plug in my computer usb ports...

Thx Doc !!!

after getting some newer hardware (well new to me anyway)...I finally made it to around 50 GH/s....I know its not much compared to some of you guys that have the S1's and all the other super cool miner high hash rate gear, but its what I could afford....and that is what matters.....
  like I said before, I am going to save my bit pennies, and maybe by fall I will be able to snag the latest gear when it comes out....but right now, 50 GH/s was a goal I set when I first started mining last winter....(I started with a couple laptop GPU's and grew from there....
  Now if we can just get over with the long blocks that would be great!!!! Happy mining!!

Hey Doc, would it be possible at some point to get a graph page that shows performance? BTC Guild has a pretty nice one that shows several different time periods. The reason I ask is I have a Terraminer IV, and it seems to be bouncing around a good amount in your pool. Based on the averages shown in the shifts page I am doing 1.6-1.7 Thps on average during a whole shift, but it gets as low as 1.3, and as high as 2.1 during that shift. I see this on the live stats page. It would be nice to see if the changes in performance were happening at certain times of day, etc. Just a thought….

The live hashrates are measured over a shorter time than most pools, so it does jump up and down a bit. It's an estimate and not accurate. The shorter time we measure that over, the less accurate it will be. Also, if you set a minimum difficulty and set it very high then there will be more variance which will cause the hashrate to be less accurate. I'll think about changing the measured time frame for the live hashrates. I could show the shifts average hashrates as a graph in addition to as a table, but I guess it wouldn't really help much.

I don't have an U2 but afaik they are the same hardware as the U1's (which I have a bunch of). For me some couldn't go up to 2GH/s without throwing HW-errors in the 50% range. The problem is with the quality of the chip. Some need a little bit more voltage than others. So I think the only possibility for you to get all of them to 2,2GH/s is with a little voltage mod of the not so good performing ones. For me I only upped them about 0.08V but that did the trick. Your computers usb ports "should" be able to supply enough power or shut off completely I think.

Thanks for the response. It makes perfect sense. I still have my difficulty set to default, which I believe you have set to 20 correct? Is this still what you would recommend for my hashrate?

Thx, one running at 2,2 and the other at 2,1 without problems for now !

Hi,

I have a questions as to how the "Your Score" percentage is calculated. For example, in the 10 most recent shifts I have somewhere between a 0.0514% and 0.0540% with 243Ghps to 248Ghps.  Is the percentage based on my Gphs relative to the total hashing power in the pool during the time of the shifts?

The reason I ask is twofold.  First, if I add more hashing power and the total hash power of the pool is not significant increased when I do then I assume my percentage would go up. Secondly, if I were to move to another pool that has 10x the total hashing power of BitMinter, while maintaining my 248Ghps, then I assume I would see a significant drop in my percentage allocation of coins.

Is this correct or am I totally off base?

Thanks.

Basically that is correct, although the score is first calculated as score = proofs of work divided by difficulty, then the percentage is your share of the total score.

Your score goes down if pool hashrate goes up, and it goes up if your own hashrate goes up, that is correct.

Just wanted to say thanks! I've been mining on Bitminter for close to a year now and have experienced great uptime, no issues with payments, fair rewards and no hassles. Hope you can keep it going and that it continues to grow!

Hello Good Dr.,

I just noticed in the release notes for Bitcoin Core 0.9.0 that the block maturation time has change from 120 blocks to 101. Do you know the reason for this, and will Bitminter change the block maturity time to 101 blocks as well?

From https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-0.9.0.md

"Consider generated coins mature at 101 instead of 120 blocks"

[syber]

I'm shopping around for a good pool and have seen bitminter, btcguild, and elugius as one of top more professionally run pools thus far.
I'm looking to contribute at least 4-5 TH/s to a pool but I'm wondering where to start when I'm connecting from south east asia (TH).
Any feedback or suggestions would be helpful. I wish I had these setup in the US but unfortunately that isn't a possibility at this time.

Awesome! Great to hear that we'll be getting faster payouts.

Hi,

I recently purchased a Corsair CX750 for my Antminer S1. Has anyone successfully run 2 S1's off of an CX750?  Any issues/cautions? 

Thanks.

Probably not a good idea.   Do not overclock them!  If you slightly underclocked them you could get a nice safe margin.  I use 900W supplies for 2 S1's.

Yes ideally, you want at least 20-30% headroom for reliability and not too terrible efficiency, 50% if you want the best efficiency and lowest noise (Considering most of the fans are thermostatically speed controlled these days)
