1070Ti for $479.99 -- no QTY limit.

I grabbed a dozen of them this morning.

Before everything went nuts back in December a good price was only $10 less than that... so not too bad!

Profits were a lot higher back then too, though...

Goodmorning everyone

sorry my bad english google translate from italian.

congratulations for the work you are doing and the passion you are putting

I can not create the image of ubuntu 16XX is constantly restarting someone has suggestions?

I thank those who can help me

If the image isn't corrupt and was burned to the sd card properly, it is most likely one of two things (I encountered both with my odroids):

The sd card isn't fast enough (odroids need Class 10s in my experience, with Sandisk working well for me)

The power cables from your PSU aren't a high enough gauge (write the company you bought them from and find out, they need to be 18AWG or larger)

Have you tried a different image? One of the odroid or mining pre-fab ones perhaps?

Count me in if we get enough volume; quantity will depend on pricing and progress with the devs for the wares, as I am too much of a novice to program them myself (currently, anyway). As such, also happy to pay dev fees or donations.
284  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain Launches the New Antminer B3 Miner on: May 21, 2018, 11:07:33 AM
Anyone else not able to connect to antpool after the update? All my payments have been marked "paying" for a couple days now, I'm patient there, but since yesterday afternoon the pool is reporting I am not connected, while the B3 has been happily mining away at 1mh the whole time, reporting no errors...

EDIT: solved, perhaps. One of two things was required:

rebooting the miner a second time after the second update
deleting the password line (I had previous left the default "123" and had no problem, or one of the upgrades had added it, I honestly don't remember)

So if anyone else encounters this problem, I suggest multiple reboots and making sure the upgrades didn't change your settings in any way and/or your password field is accurate or blank. I do wish I had done one at a time so I would know which was the problem, and would play around to figure it out but I lost 15 hours of mining so I'm not touching a damn thing. Wink
285  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain launches the Z9 Equihash miner on: May 21, 2018, 09:49:21 AM
heard from a source that batch 1 was 20-30K units.  

do the math boyz  Shocked

I've done the Math, Their are plenty of decent equihash coins to spread out the hashrate. Komodo, zcash, ZenCash, zclassic, bitcoin gold, bitcoin private and so forth. Not a lot of them will fork off soon or at all.  Sounds like they will take their time like Zcash by end of year to fork off. Most of them gave no response.  GPU mining will die off of the equihash algo but by no means this will turn into a D3/A3/L3+ brick miner which only had 1 good coin to mine.

Actually on Nicehash (and doing some tweaking) you can still turn a decent profit against elec. expense on the D3. I mean, not a lot daily or anything, but worth turning back on in comparison to energy and profit of any other miners from last year (or even the A3) with exception to the S9. It’s definitely more profitable than the L3 right now. But yes, ROI is unlikely, I just mean if you have one laying around...
286  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain Launches the New Antminer B3 Miner on: May 20, 2018, 07:22:03 PM
For those who upgraded their fan, you can skip the fan speed update and just perform the second update for the hashrate.

The problem with the fan speed update is that it will set fan speed to 50% so your replacement fan will be too slow to cool the B3 down.

Didn't happen with mine.
287  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain Launches the New Antminer B3 Miner on: May 20, 2018, 08:46:14 AM
Just thinking ... when you consider Bitmain could propably have shaved 10-15USD of their production cost per unit (x3000 units?) by not using 2pcs high RPM fans but using some other cheaper fans, and they can now add 30% hashrate with a firmware update .... makes me think the B3 has a lot more hashing potential than currently announced.

I also noticed in one of the first B3 youtube demos how high the utility rate was on the status page ... utility rate as in how effective the miner works (miner status page, top middle). My B3 utility rate before the firmware upgrade was 0.9 or so, now it is at 1,13 ... the youtube move showed 9,7 if I recall well (https://youtu.be/aavqAi--Z7k @5:05)

So I think the B3 hardware can hash a lot more than what Bitmain is allow us to hash currently, if my assumptions are correct, they have a lot of control over all parameters that determine difficulty, network hashrate and as such the price ...

I kind of assumed this since this is the first antminer I’ve owned that you can’t alter the clock speed of...
288  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain Launches the New Antminer B3 Miner on: May 20, 2018, 08:45:23 AM
For you folks who replaced your fans, be aware that with the new firmware that increases hash-rate, the chip temperature will also increase.  Might wanna keep any eye to ensure you're getting adequate cooling.

This is exactly why fans should not be replaced in the first place. Get those quiet box instead if u dont have a noisy place to put it.

Why? Because we may end up having to test every now and again? I’ll tak my 30d drop, thanks. Smiley
289  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain Antminer X3 -- 220KH+ Cryponight - 550W on: May 18, 2018, 02:08:52 AM
Lots of pools to choose from. Getting 1591 etn  270 Kh/s. (at fairhash)

I'm overclocked    to 475hz. Temps near 54/53 C.

Gotta keep it going until Fork time.



Overclocking is tempting but I'm too afraid I might mess something up or hurt the longevity of the machine if i want to host it in a facility long term.

That's totally valid, but considering the length of Bitmain's warranties and the speed in drop in profitability of the past couple miners they've sold (D3, A3), there's not a huge risk if you're careful. Not promoting or even necessarily condoning overclocking, but I do it. I have my L3+ overclocked for 6 months with no problems, the A3 for the two months it was worth bothering running it, and have my X3 overclocked as well. Just make sure your temps are good and your HW errors are low if you try it.

Think of it this way: if profitability the first 2 months is 5-6x that of later (using the A3 as an example), overclocking for a 30% bump is totally worth the risk if you can get those results for that whole period, even if it dies say 4 months in. Using the S9 as an example, it would probably have been very profitable to overclock it on arrival, but that machine was profitable for a very long time, so if it did kill it within 3-4 months, you might have ended up losing money. It's all about the risk/reward.

Also killing your machine limits resale to parts only, but I don't think that's as huge a loss with the current era of ASICs.


Agreed, I'm a bit conservative in the Oclocking. 475hz  getting 270-280 Kh/s. Some on youtube have Oclocked to 320 Kh/s. Only one bank had 8HW, temps are arounf 53-55 C

I have mine at around 320, though I am averaging between 290-310 on fairhash. Freq 550 if you're interested. All my temps are below 60 and I average around maybe 6 HW/day.

Yes. I would write support (and definitely change it back to yours, and maybe change your password?).

Does anyone have some insight into batch 3 date for the B3's?  I would hope bitmain would at least let us mine batch 1 and 2 for one week before they drop the earnings to $7.... 


I checked my payment history and its in paying status BUT.... its showing a different address than i provided and my originally provided address is deleted...  can anyone tell me if I should be nervous...??

I have the same situation. My wallet address is empty now under my settings.

My guess, since the ERC20 comment is gone too, is that they switched to BTM payments and deleted any non-bm addresses? Not sure; it also reset the minimum payment to 5, but still isn't paying out for me, so I have no idea what's going on there...
293  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain launches the Z9 Equihash miner on: May 17, 2018, 07:16:34 AM
Looks like Batch 2 is avail..
Shipping: August 24th- Sep.4th

$1520

They must be getting low on availability for the june delivery..




I suspect it is to show that 2nd batch will be some time away. People are afraid the 2nd batch might be the next week, just like how the B3 was.


For the 2nd batch, woah

2. We are currently accepting pre-orders for the Z9 mini. You can place an order by paying 50% of the order amount as down payment. Please note that the outstanding amount must be paid by the end of 1st August 2018 Beijing time(GMT+8).  Kindly note that as this is a preorder, the 50% down payment will be forfeited if you do not complete the payment by 1st August 2018 Beijing time(GMT+8). Please consider carefully before submitting your orders.

Hmmmmmm

It says "can". You can also just pay in full like usual and not worry about it, though honestly I'm not sure what the benefit is to adding this policy (aside from free money from lazy people, I suppose), unless they think some potential Z9 buyers overextended themselves on B3s and X3s and want to give them the chance to earn more with them to pay the rest of the bill? Seems weird.
294  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain L3+ Voltage Control Tool...Free :) on: May 16, 2018, 10:24:20 PM
I used the software that @jstefanop has put out here on 2 L3+ units last night! Excellent!

I used the WinSCP to do it all - I have Putty on my system, so not sure if it picked up on that or if it has it embedded in the software or install, but once I established a connection to the miner with WinSCP, I was able to open a Putty window from a button in WinSCP that opened right to the miner already connected to - just entered password and followed the directions.

Anyway - I will write more on it later but the end result was that I got them both running at the lowest power (0xfe) and was able to clock them both up to 394MHz (~515MH) without any issue. I recorded temps at each step and after clocking up to 394, the temps were back to about the same as they were running at 0x80 (normal voltage factory setting). So I ended up at about 15% less power use with about a 2% increase in hash rate with temps staying in the same ballpark as they started at. I was getting no more HW errors that before with this config - I was targeting lowering power use, then improving hash rate - while maintaining similar temps. I'm sure I could have increased hash rates by more than 2%, but I didn't want the additional heat. My miners are running overall hotter right now than I want - getting ready to move them to a cooler place with better airflow, but until then, I need to keep the temps in check.

Very Good!

Now - I have two L3++ units as well. They are running at 450MHz from Bitmain and running generally in the 590-600MH range. So my question on these - is there already any kind of automatic voltage adjustments going on with these L3++ units? Their MH number seem to be fluctuating much more and much more constantly - like something is being adjusted constantly. My L3+ units stay around 502MH to 503MH very consistently (well, now 514MH to 517MH  Smiley ) - but these L3++ units are bouncing around probably 570MH to 615MH constantly. I mean I just site there watching to numbers fluctuating none stop (using Awesome Miner). So I just wanted to see what you guys think - I know I saw someone else had used this on the L3++, but just wondering if it might interfere with Bitmain's settings if they may be messing with an auto voltage system design as well.

Also, one of my L3++ units has 1 hash board that is running a little more than, but pretty close to, 1 HW per minute with factory settings. Is this worth contacting Bitmain over? I'm wondering if dropping the voltage on this unit with this software from @jstefanop will potentially ease that number down - less power - less heat - maybe help improve the HW rate?

And lastly - I had a thought/concern about the lower power settings. When running electrical - it is always better to use heavier wire as it is more efficient at carrying the electricity: less power loss due to resistance (generally lost in the form of heat) and improves the watts used by the connected equipment, etc... When doing electrical runs that are too long for the gauge wire used, you frequently hear about how that can damage equipment due to the power reaching the connected devices not being strong enough - too much lost in the transmission and the overly low power somehow causing damage to the connected devices. Is this is a concern here? If we lower the voltage down to lowest setting - is this somehow stressing the miner's components in a way that might cause them to fail earlier? Should we look at lowering the voltage some, but not to the lowest settings? I don't know and am truly asking. What are your thoughts on this? I am very happy with the idea of lowering heat, power costs, and/or even getting improved hash rates - but...

Thanks!

Play with your settings. I was gettin 620 out of my L3+ for months stably with decent temps.
295  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain Launches the New Antminer B3 Miner on: May 16, 2018, 10:19:12 PM
So, what's the profitability?

Currently around $15/day. Roughly. It's hard to tell right now.
296  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain Launches the New Antminer B3 Miner on: May 16, 2018, 01:43:43 PM
vosk if your miner fans are quiet can you give us firmware of it? everyones b3 is louder than any of the mienrs


You can just replace the fans. Get a low noise high static pressure fan for the push and any low noise decent speed for the pull. The loudest thing in mine right now is the psu (and the actual sound of the computations).

Here's the one I used for the push:

Hello,

Mining coins with your miner isn't very profitable but I've done some research and a few coins could make you (a little bit) of money.

First of all (probably the most profitable) is Deep Onion. This will make you about $3.70 a week.

Then Quark. This will make you about $1.70 a week

And firecoin looks interesting to me but i didnt find any calculators for that.

Sincerely,
Daehworra

With your calculations it will cost me 1.5 years non-stop mining to earn my invested bucks back.

Great perspective...

That's not a perspective, it's math. Your miner isn't very profitable. You can learn a lot with it, and maybe you'll get lucky and mine something that will be worth a bunch in the future, but if you were looking to cash out on the regular you're simply not going to make much.

If you get your money back then you will be better than 90% of trolls who threw their money away in the drain, most of you trolls just think an asic will make you rich, the only thing that is getting richer and richer are asic companies for your undeniable mindless support ehhe

He/she just bought it. It's a two year old ASIC. They made someone on ebay richer, not Baikal.

And I really don't think they are trolling.
299  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain E3 Ethash Miner ASIC (Shipping:16-31 July. $800 USD) on: May 15, 2018, 10:23:37 AM
Both the E3 and Z9 are big gambles.  There may not be enough time with either miner to even get the ROI.  Right now coins on equihash are talking fork.  So it makes the miner questionable at the moment.  If they don't fork GPU miners will start to leave in droves looking for a place to park their hash and the likely place is ethhash coins.  So up goes diff and down goes your chance of getting an ROI on the E3.

So I would only risk funds you are willing to write off at this point as a loss because the risk is pretty high.  Everything is in the air as the devs decide if they are going to fork or not. 
There's not going to be any forks. All you folks spreading that need to read this article;

https://blog.sia.tech/the-state-of-cryptocurrency-mining-538004a37f9b

If you don't read this in it's entirety, you'll never understand the ineffectiveness of forking Coins, to combat ASIC. It DOESN'T WORK. I'm sorry to break it to you, but GPU mining  is dying and will be dead. I'm not happy about that, but it is the reality.

Not saying anything about the E3 or Z9, but it worked pretty well for Monero.

These fans are irritating, editing the miner conf on putty didn't work for me, the fans speed wasn't getting registered in the GUI before hand so I got separate fan controller to plug the fans into, to manually change the speed.

I just swapped them out for the same low noise Corsairs I use(d) on my S5. Whisper quiet now, so much so that you can hear the actual chip noise, and temps all below 60 (highest varying from 55-58 depending on room temp) upstairs on a hot night; I expect that to drop significantly when I move it to the basement. No HW errors yet, hash rate seems roughly the same as stock (averaging around 800)...
