Files changed in /config are permanent across reboots. In the S5 there is a file /config/user_setting which has just
I'm not sure if the S4 is the same but if it is, that's all you need to modify, to say queue 1

I'm so confused!!! According to the website, these come with SP35 units.  Either 17 or 36.  That's $.18/gh + a container.  If that's not a typo, I want one!!! or two!!! or three!!!

Ok so there are 2.94 BTC to be donated. I was thinking of donating them like this:
- 1 BTC to the /r/millionairemakers winner (see: www.reddit.com/r/millionairemakers/comments/2q9ung/santa_is_real_thank_you_all_so_much_i_am_still_in/);
- 1 BTC to Hal Finney Bitcoin Fund for ALS Research (see: http://blog.bitcoinfoundation.org/join-teamhal-give100-wbitcoin-to-the-hal-finney-bitcoin-fund-for-als-research/);
- 0.5 BTC to ckolivas for cgminer and ckpool;
- 0.5 BTC to Armory.

Any complains/suggestions? 24 hours max.

Difficulty is going up in 4 days, not next month.

Yep, they work perfectly with p2pool. Bitmain addressed the issue with the firmware they released on Oct. 16th, more or less. For slightly better results, it's best to use ck's firmware found here: https://bitcointalk.org/index.php?topic=796839.msg9242449#msg9242449

Agreed, it would be like a long visit to the dentist waiting for those shares, but you would expect to find one share for each block, here is an example of a miner estimated at ~500GH/s:

http://minefast.coincadence.com/miner.php?id=1LavTqNGUSwS4qHWK1d8ZRNQjCxU3bouYQ

There is a minimum amount of hash power to expect a share in each block found, as the pool rate increases so does that minimum power requirement.

Right now I'd estimate around 500 GH/s as a safe minimum based on current active miners with payouts.

If you go to the global stats page, click on the active miners tab and sort by estimated hashrate you can get an idea of the minimum.

I'd appreciate any feedback on the node's performance. It's running on high end hardware, SSD, and is connect to the internet VIA a 175/175Mbps fiber optic connection.

That could be aided by big miners setting higher difficulty shares right?

Bitmain gave me 12 S5 coupons, I am still waiting to making decision what to buy.

more reliable nodes ? spread the word, more support for each other & developments for p2pool

i have 2 myself & helped a buddy to make 1 on his own.

Please try setting the pool side DIFF to 2048 or +2050

You can try connecting to BTCGUILD.COM and see if x goes away or hashrate goes up to where it should.

The hashrate you see on the control panel and the poolside may varies due to many different factors.  Our guarantee is the machine side hashing rate


Thank you!

was a windows application...

Operating in linux£º
1.Change to root mode using "su" cmd.
2.Insert SD reader with SD£¬linux mounts device automatically. Using "umount /dev/XXX" to umount device. XXX is device's name.
3.Using "fdisk ¨Clu" to check disk device in linux.Normal it is dev/sdb.
4.Copy omap3-mkcard.sh to linux system£¬add execute mode using "chmod +x omap3-mkcard.sh"£»"./omap3-mkcard.sh /dev/sdb" to part SD.
5.Go to /mnt directory£¬mkdir mmc1£»mount /dev/sdb1p0 mmc1.
6.Copy MLO uEnv.txt u-boot.img am335x-boneblack-bitmainer.dtb uImage.bin and initramfs.bin.SD to /mnt/mmc1 directory.
7.Umount /mnt/mmc1.
Only step 5, 6 and 7 are necessary, if SD is partitioned.

''Just Works" is useful. But if it means a metal case instead of a plastic case, I say save the money. Anything that can be done design wise to reduce the manufacturing cost of a product with an expected useful lifetime of less than a year is worth doing.

I am running 3 s4's since 3 weeks and have few doubts to be clarified by any experienced users. Our machines are hosted somewhere else.

In the beginning hashrate was very unstable and after upgrading to latest firmware, they became lil stable. I use p2pool.

-what does hard reset mean? In-detail please?

-1 of our miner has lower hash rates with 1 or 2 'x' asics failing always.After running it for sometime x starts appearing. Contacted bitmain and they said to test each blade and we did all troubleshooting stuff and they worked fine when connected to separate blades. Again after connecting all, 1 'x' appeared and hashrate is slow after 10hours compared to others.
For example on p2pool with default 200mhz,725v on p2pool with pseudo,actual difficulty set to /8192+8192, hash rates are as folllows after running them for 6days :
miner 1 : 1970gh
miner 2 : 1965gh
miner 3 : 1850gh ( which has asics failing issue)

All above stats are from antminer panel and p2pool graphs shows a different story. All 3miners work with same worker.
deadhashrate overall for 3 miners on pool is 270gh. shall i set difficulty to 4096 for a lower dead hash rate or is it something to do with pool?

- I am planning to overclock the frequency to 212.5mhz on 725voltage. Will that work or any consequences? I have seen people doing 225mhz with 725volt.

comments are appreciated. Thanks

You can use http://sourceforge.net/projects/win32diskimager/ instead.

For S4, if the miner powers up, the back light of the small LCD comes on but screen shows blank, highly likely it is the MicroSD card either got loose inside, or data on the microSD card got corrupted.

You will find the MicroSD card inside the case, behind the LCD panel and next to the PSU.  There is a Black Colored Beagle Bone Black and there is a little MicroSD card slot on it.  Lightly push the card and it will pop right out and push it back in.

Then please try to power it back on and see if it boots up.  If not, you may have to use this software to reimage (Write) the factory default data of S4.

That is almost always true in this game, at any time, with any product.
In fact, products go from coveted to worthless in a blink of an eye.

With product usable lifetimes so short, who wants to pay the extra cost for an over-engineered product ?

I have two SP31 hosted with Toom.im and I am very pleased with their service.
Both machines were set-up straight on arrival. They really know SP very well and will assure you the best settings.

But they are nearly out of space for hosting so I would suggest to quickly contact them and see if there is any spot left for your project.
