Well I finally got my ball bearing fans in for the stock replacements.

They work well but they are extremely loud compared to the stock sleeve fan.

They are the same type/brand as the stock fan, just ball bearing, direct replacement.

You probably bought one that is really high RPM...these fans can go up to 15k RPM. You only need about 7-10k RPM to properly cool these. Stock fans run around 9-11k.

Looks like all the lucky guys that just plugged them in will be earning ~20 bucks an hour for the next few hours lol

Whatever dude, you keep investing in what you want and I'll invest in what i want.

He wasn't trying to predict the price by charts he was just showing the lead up to 10 cent all time high.

I don't really think a 10x in a year is to unrealistic for a top 20 coin

New people in crypto get tricked into this kind of thinking...why do you think all the new coins have hundreds of billions of coin in circulation?

The PRICE of a coin does NOT matter, the only thing that matters is its market cap based on # of coins in circulation.

"Ooo look Sia is only 5 cents...one day it can easily go to 1,000 if bitcoin is 20,000!"

umm, no Sia will never go to 1k, and if it went to $10 that would be an extraordinary feat (since its valuation would be more than all of Bitcoin's).

All these new coins with their billions of coins in circulation is just marketing at its finest trying to trick all the crypto noobs out there.

i have tried claymore settings:
-1100 cvddc -1100mvddc -1100 cclock -2100 mclock
to
-850 cvddc -850 mvddc -1250 cclock -2250 mclock

Please guys, if you have any idea what i could look for to get this baby stable it would be much appreciated.

If you think you will have a stable rig with modified timing and over 2000 mclock that will never happen. Start at like 1900 mem clock and move up until you find whats stable.

I think I had one of mine die sometime this morning -- it shoes 100% HW error rate at 700mhz. It hashes at like 83.2kh and constantly stops hashing/restarts.

This is a completely different unit than the one I mentioned a few posts ago.

What frequency were you running it before it died?

Quote from: MrJaekin on January 19, 2018, 02:32:42 PM

So, does everyone think the boat has passed on this one? Is it still smart to grab one on the next batch? Even it difficulty jumps 5x, you'd still be making $100 a day or so...

Ok, I know there are a lot of new people here these days, and most people don't understand the math of mining so here is crash course before you get burned.

Currently SIA has a combined hashrate of ~500TH...this is the combined hashrate of all GPUs currently mining on the network (most GPUs do 1-2GH if your mining SIA direct). All it would take is JUST 600 A3 units to just DOUBLE the current hashrate/diff.

Once the 6k chinese units get turned on next week before any of you have your A3's the network hashrate will spike to 4,800 TH, thats a 10x increase from today, so that nice little calculator you use that tells you you will get rich in 10 days will go from $600 a day to $60 a day before you even get it.

Now double that again once everyone else gets theirs, and your down to $30 a day the first day you start mining.

The problem is that SC-1 is basedon 28nm, I bet that antminer A3 is on 28nm as well ( considering GH / power ratio). It is very old and outdated technology compared to nowadays available solution. We will see much moe faster miners very soon.

Almost guarantee that they are on a 40nm node for the first gen chip. 28nm is not that old and still requires a pretty large investment. Most Litecoin ASICs are still on 28nm as well.

I think those who will make the most money off these are the people selling them on ebay for $7500 each at the moment. I truly can't believe people are that ignorant to pay $7500 for a miner that in all likely hood will not make 2/3 of that back.

The trick is to get the machine, list it as a 7 day auction, let it mine for 7 days before sending it off, profit!

Yes, but in the time it takes to get miners here in the US how many of those 6000 Chinese units will be online in the next 5-7 days and destroying the current diff of the coin. What will it be in 3 weeks when the miner is received Sad

What will the prices on ebay be going for then... 3k?

If anyone believes they are going to be making more than ~30 a day after these ship out, you are quite delusional. Its going to be fun watching the diff charts on this over the next week Cool

Update:

Batch 2 units are currently almost finished production, and pre-order units are now being shipped to Distributors. You guys that placed early pre-orders should start seeing your units being shipped next week!

Batch 2 in stock units should start showing up on Distributors websites by the end of the month for everyone that missed the pre-order.

Ok. One of the things I wanted to find out with the debug mode is WHY the hashrate drops to around 2.5M/s, is it because some cores stop being activated (after a restart), is it because some data doesn't get transmitted, (USB hub clogged up has been suggested). I know it drove me mad at one point, but since now everything is stable (running 11 sticks on 1 hub at around 55Mh/s total) I am happy.

Running 10 ML2. Can't seem to get past 3.5Mh/s on average. I have 2 that drop to 2.5 Mh/s which brings the average down at 744 Mhz. Even if I raise the freq, the hash eventually settles at 35 Mh/s. I'm thinking it is wattage at this point. Using Sipolar A-400. Haven't played with the memory voltage, but maybe it is time to play with that because I think I've hit the wall in terms of 120W (12 W per device) on the Sipolar A400.

I have seen this as well, I have narrowed down the issue to one of two things.

1) like 90% of the issues I see this happen when your running multiple sticks on a hub and your near the max Amps the supply can generate. This causes some cores to shutdown and you see the drop in hashrate
2) some ASICs have a larger than normal power draw on memory, the issue get worse on frequencies higher than 600mhz. The memory controller then overshoots the voltage past .9v which causes some memory banks to stop working. The fix is to turn down memory voltage as low as you can get it to start hashing. Seems like .75-.8v works (almost a quarter of a turn counterclockwise on the top pot).

Next driver update will have an additional watchdog that looks for low hash rates and restarts them, but hashrate will still keep dropping if you have an issue with supply etc.

Would the fans on these fair better if they were oriented differently?

It is a sleeve bearing right? I'm thinking it might be better if the usb hub sat on it side, so the fans could lay flat.

I run mine flat, not vertically but I have direct replacement ball bearing fans coming.

Sleeve bearings run better horizontal, if your run them vertically the perpendicular forces against the shaft will start wearing the sleeve bearing faster than normal and it will start vibrating more. Ive run these fans vertical and so far most of them are holding up fine after months of use.

25% increase is called greed.

Im sorry you are expecting to pay the same price as the people waiting 2 months for these. I could easily set the MSRP at 149, and they would still sell out but Im not, because this project was founded on getting a cheap miner in the hands of as many people as possible, which is what we are doing.

Quote from: aarons6 on January 14, 2018, 12:53:38 AM

to anyone curious, this is stock voltage at speed 796

this is why you need a good hub and why you cant plug these directly into the usb ports on your pc

FYI you can easily pull ~1.6-1.7 A @796 if you turn down your core voltage a bit and memory voltage.

Quote from: dalabrac on January 14, 2018, 07:22:20 PM

I'm having some difficulty tuning mine. I have it clocked @900, tuned so HW<1%, but the hash rate won't stay stable for more than a minute or so.

Try turning up the memory voltage as well if your going that high. Again, anything past 900mhz your burning through 3A of current, you would need a super heavy duty hub with a very good power supply to be stable at that high of a frequency.

Is it possible to get what the market price will be from the distributors? Amazon a few weeks ago had them listed for 160 a piece, I think now one person is trying to get $200 a piece. Ebay your looking at around $200 also "Buy Now". If I'm correct preorder was around $67. I read in this thread the price will be somewhere in between. I have been saving my change, would be nice to know what we can expect on the market. I would assume a fair price to be around $85 - 90. If I'm off just say higher or lower.. Because I have no idea really.
Thanks,
Scott

Any Batch 3 coming out soon?

Only jstefanop knows :-)..

No plans currently, Batch 2 will start shipping out to Distributors next week, and we have LOTS of inventory. Once Batch 2 pre-orders are shipped out you will start seeing in stock units listed towards the end of the month from all my distributors.

At this point going forward I will have enough channel inventory and steady production to keep these stocked everywhere. I might do one more pre-order batch 3 only because there will be a month gap in february due to the chinese holiday and the parts I source from china wont be available until March.

Batch 2 pre-order price was $64, Batch 2 MSRP price that I am setting with my Distributors is $79. Thats a suggested price, I can't really force them to sell lower if the market demand is there to sell them higher. I am trying to make as many as possible to saturate demand, but the reality is people want these and will pay extra for them.

Where are getting that "clock freq" from? Maybe I missed something.

Quote from: charlie137 on January 09, 2018, 11:48:29 PM

the setup hasn't changed for weeks. i used to run them on 768 with zero problems, so this is not he case

Well, you are getting around 4Mh/s for MLD0, and 700Mhz gives 700*5.66 (see page1) = 4.0Mh/s, so normally that means 700 or maybe 720Mhz. At 768Mhz you should get 768*5.66 = 4.35Mh/s and you are not getting that by far (MLD0), so no matter what I think something is wrong and it could be powerdraw. Why do you think you have zero problems if your hashrate is substantially below target? Or were MLD0 and MLD1 properly hashing at 4.35Mh/s in the past _and_ both have gone down?

current setup is 720Mhz. i used to run them on 768 but speed gain wasn't big, so i tuned back to 720. it worked for weeks on 720 with 8.20mhps total until day before yesterday

Try going back down to 600mhz speed and see if that resolves the issue, could be that you were near the max of what your USB supply could do, and its failing to output a clean max supply after a few weeks of use.

I was running the stick for a while without any problem, but recently all of a sudden the bfgminer log started to look like this:

etc

So it still hashes, but with frequent errors and at degraded hash rate.

All settings are default, I never overclocked the miner. No configuration changes (which I know about) were made. Powered USB hub.

What could it be?

Looks like something weird is going on there, you got shares coming from a Zeus board? Did you custom compile the driver and try and run both at the same time? That is most likely the issue as Zeus commands could be messing up the Moonlander.

Quote from: kcw-grunt on January 08, 2018, 09:23:20 PM

It isn't being said so I will just confirm my suspicion is that since the MLD driver (for FB MLD v2) is not merged with the main BFGMiner repo, the BFGMiner won't config file won't work with FutureBit Moonlander 2...@jstefanop ?

I have to make a script to add all my custom goodiness for each miner? Just trying to see which direction I should put my resources into..

if you mean loading sittings via config.txt, yes that works fine. My branch is just a clone of bfgminer, with some things not specific to the moonlander disabled to help with debugging, but all the main features of bfgminer work with my build.
