Cex do and will continue to payout using bitcoin but if you have any doubt about that you can easily contact their support or check the FAQ.

I can verify this. If you have trouble with confirmations make sure to contact their support team.
They usually reply within 1 day.

I have it as my Fail Over, no problem here. I've collected no problem so far. If you go to the block data page it says how many confirmation until the BTC gets credited to your account.

With an s7, rule of thumb is :  overclock if you want, underclock if you want, find a good setting with sub 0.01% error, and then - DONT TOUCH IT EVER AGAIN.  Smiley  Also check out the luck we had at Kano.is pool SmileySmileySmileySmileySmiley

Only thing is if bitmain catches you doing overclock it will void warranty.  Current batch 8 I have not seen a overclock to make it worth losing warranty for.

Chances are they will not catch you.  But it is possible they might depending on problem you have. (Which hopefully there will be no problems and not need warranty)

It seems they won't warranty the product anyway.

I lost another b8 hashboard today. It was underclocked at 675.
Guess I shouldn't have moved it above 650.  Still no word on the 2 batch 5 boards I sent to Bitmain.
Will be 4 weeks on Monday.  This batch 8 board had been running 3 weeks.  Lost another batch 8 board running stock 700 about 10 days into mining.
Emailed Bitmain about it and again - no response.

Thats odd. What is your PSU setup? Are you using surge protectors? Unless you have thousands of S7's i dont think there should be so many failures.
I've purchased the following (48 x S7 total):
17 x batch 1 units (not a single problem with any of the batch 1 units since received)
1 x batch 3 unit (no problem with it)
20 x batch 5 units (1 Batch 5 had 2 boards fail early when there was a small internet outage.)  I seemed to have missed the manual fan speed on that unit.  No problems with the other 19 units.
10 x batch 8 units (1 board failed at 700mhz speed with temps around 67c at 10 days into mining - second unit had one board fail at 675mhz and again temps around 67c).

So now 4 failed boards out of 144.

All units have surge protection, and there was zero indication of surge as none of the other miners stopped mining.

On the 2 batch 8 units, the miners just became un-responsive.
First unit when I power cycle PSU will spit out some extensive errors on the hashboard and then reboot itself and come back up with ----- ------ ------ ----- on the board.
This second failed board will show 35 chips in the GUI, but will not attempt to hash on that board.



I see, but i have fluctuation on certain circuits that i don't have in the other. I'm not talking about a lightning hitting your house hitting all your miners kind of surge. What are the PSU's? I've noticed a lot of PSU that comes cheap dont have UVP/OVP protection which would also possibly fuck over a miner.

@VirosaGITS How much electricity PSU for S3 will consume, if equal to a simple desktop computer than nearly no issue. and as compared to buying bitcoin of $100 which option would be best for me?

Its a bit more, 355 watts at decent efficiency. But thats not the point, even if its not much, it would still cost money to run. If the electricity you're using is at 0.1$/kWh, then you would not generate any profit at all, therefore simply buying BTC is much better.

If your electricity is truly free, then it is going to take 4 months to generate the BTC you could outright buy with the 100$. Also finding a PSU AND S3 for 100$ is going to be hard.

Why Bitcoin.org is so weak on Facebook?

There are only 1100 followers. In forum, it's obvious that there are more active users than this.

Because Facebook is useful, but its not something i mix with online activities and there is no central authority promoting Bitcoin.org, nor is there really a reason to promote the website itself. The news are somewhere else and its quite possible the Bitcoin.org group is not from the official group.
1445  Bitcoin / Hardware / Re: Avalon 6 - Firmware Upgrade Help Avalon6 on: January 10, 2016, 03:08:36 AM
Never do firmware updates.

Simple rule has exceptions.

First does your gear work with current firmware?

If yes don't do a firmware upgrade.

So are you mining  with the rigs?

If yes don't do a firmware upgrade.

Mine with the rigs as they are.

Show us your mining stats.

Then discuss firmware upgrades.


I have two avalon6s I have stock firmware. My gear works fine.

No newer firmware has results better then what I am doing.
If you reall want to upgrade don't do it for now.

I would agree I have 2 using stock firmware aswell.  If it is not broke don't fix it.   It needs to be a big feature or flaw for me to update, I don't think Avalon 6's have this.  It is very stable with stock firmware.

With reading your post's I would be a little worried if you try to do a firmware update.  I suggest leaving it at stock for now.

Should be okay if he clone his SD card and mess around with firmwares on the copy, so if it fucks up he just need to restart the Pi with the good SD. Its not as bad as the Antminers that dont read from SD card somehow.

Hello guys

What I know, getting started with Bitcoin is difficult, specially with small budget. I have maximum $100 to buy mining hardware. I searched, i found many options like Avalon Nano 3 etc.. But i am not sure in 2016 this will be enough for mining. I would appreciate if you could explain how i could setup mining environment with one i3 laptop + $100 money. I would prefer USB type mining hardware  Smiley.

If your electricity is near free, try to get a single S3, but you will need a PSU. Otherwise maybe Two S1. If your electricity is not near free, then no mining for you.

Yes please post a video of a before and after.

I think the best way to silence these S5 is to add a second fan and undervolt them.

I'm using this;
http://pacwestsystems.com/wp-content/uploads/2015/02/Alcor-Sonopan-Acoustical-Panel.pdf

Just a two open ended rectangle of these covering 200 degree of the miner makes the S7 at 3500RPM quieter than the S5 at 2600RPM.

About HW error rate. How to interpret is?  What is too high rate?

If ran with good a PSU at stock setting, you should be pretty much at 0. If you OC a lot you might get anywhere from 0.0001% to 0.05% its all good, its merely an indication.

You could get 1% and it would only indicate that the PSU's volt output is sagging a bit or that the OC is too high (not a danger, but lower efficiency) its not directly a problem in itself. Simply see what gives you the best hashrate. If you OC. If you don't, not getting near 0 might mean your PSU aren't very good.

I get 1.32TH/s for 400 freq. 1.27 for 387freq.

I'm overclocking. So as long as my hashrate increases, I don't need to worry about HW error percentage?

Thats mostly it. If your HWE suddenly jump to 1%, then its likely the PSU is dropping voltage output when you raise consumption, at that point its probably best to bring it down one step even though running it a 1% may be acceptable.

However when the HWE% start going up by such step for me, the actual hashrate dropped. So just something to keep in mind. A HW itself does not cause damage to the hardware.

You need to be Jr Member to have them displayed, so i quoted them for you. But the url you input are not the direct link, it has to be the direct link to the image, you're using redirecting links all over. However the onedrive links seem truly invalid. Anyways they arent working for me.

I still didn't receive my full payment personally , please check my case.

Still waiting patiently for my 200~ posts. Thanks.

I'm located in Idaho. I'm not completely against selling to Canada, so long as you are okay being completely liable for all taxes, tarrifs, etc. involved.

The mining equipment works as Avalon says it does; I am no longer in a situation that I can continue this operation, though.

Then my offer stands, but you may find US buyer willing to pay a premium because there will be no import duty, being based in the US must be nice for this. I would buy two, however.

Hi their ive been trying to set up mining for 2 days now with no progress.I am trying to mine with easy miner and it is picking up my pool but it hasn't found my graphics card and says 0 active processors. my gpu is a 980m and all the drivers are updated, any help appreciated thanks

Dunno, its a few years too late to mine with GPU, so i'm not sure why software would be developed for it. So anyhow, you're wasting your time with this, you'll need ASIC either way and then you dont need "easy miner".
1456  Economy / Exchanges / Re: Why does Bitstamp not accept Mastercard from all customers on: January 09, 2016, 07:04:52 AM
says in their webpage only accepting from certain countries using mastercard

sounds kinda strange why not any user with a Mastercard

Mostly for insurance and also protection against fraud. The risks are different depending on who they are serving. But if ID verification is possible, then it should be okay for most  countries. Pretty much how CEX.IO does it.
1457  Bitcoin / Mining support / Re: Antminer S5 board temperature difference between boards on: January 09, 2016, 06:51:00 AM
Hello,

Just wondering why might there be a large difference between the two boards in the S5?

One board shows 53C, the other 59C.

There is a box fan sitting in front of the machine pushing from front to back. And there are two 120mm fans underneath the unit pushing air upward.

Cheers!




Its normal. The blades are not mirror, so i'm guessing the sensor is a bit further back for one board considering the flow of the air. What really helped for me for noise and cooling was using 2 fans. I also used a box fan blowing air through at some point.

Its fine, information is useful. And i offered to sell you one for quakefiend's asking price ;P His price before he sold out that is!

No worries, didn't mean to ignore you, I just remembered someone mention that shipping cost between Canada and USA is a lot, so I'm trying to minimize unnecessary cost to help my ROI.

Shipping is double, but the extra 15$ is probably worth the quality, or not. Dunno. Also the shipping cost is in CAD so its probably cheaper still.

At this point is batch 8 or 9 the best deal? With batch 9 shipping in couple weeks seems batch 8 is too expensive for when it actually ships and delivers right?

not sure how the numbers add up but my b8 shipped next day and was delivered two days later, i.e. sooner than the website states

although b9 could ship sooner too

B9, especially if it ship sooner, because the difference in price with B8 is pretty much what you'd earn with the miner, so its not worth mining with it for the difference. Unless you have a B8 coupon.

I would not mind betting that this is an all time record for any pool?  Anyone know?


I have never noticed those luck stats at any pool in over 3 years...........
Heh look at the luck graph ... you'll see this is the 3rd time it's happened.

The first time, we had 17 blocks in a row (under 100%) averaging ~30% diff Smiley
Block 7 to block 23.

You,re obviously padding the block reward out of your own pocket, by renting ghost hashrate and ghost substituting it with some "legit user"'s hashrate.

I'm kidding, but people start saying "something must be wrong with the pool" when we're at 200-300% diff, but i don't see anyone saying "there must be something wrong with the pool" when we're at 600%+ luck. ^_^"
