About the LEPA 1600W psu, i use 8pin CPU to 6pin vga adapters and i have no problems!

My batch 1 is online for  1d14h10m58s running at an average of 4,811.82gh on LEPA 1600w

I want to power my s7 with a LEPA 1600 also.
do you have time to explain or show pic I'm unsure because of the rail distributing.

I think i will use 2x 4 pin Molex to PCI-e  for the control board

I than have 8 cables left, I could use 2x 4pin Molex to PCI-e on one of the boards?
I have them available.

CPU to PCI-e I must buy first.

Safety is my main concern, I will do no over clocking till warranty is gone.

Update on my OCed S7 - It's a tank:




did you only set up the frequenzy to 650 mhz to get 5.2 THs or did you any changes else?

. You all seem to give a fcuk on anonymity and also give a fcuk on keeping the chain well distriputed and healthy by your greedy poolmining...


Hmmm.  Using BitcoinCZ stats as a basis, my current 6.7TH of ASIC farm ((2) S3s, (3) S4s) pays about 0.005 BTC per found block and that pool finds half-a-dozen or so blocks a day.  If I'm doing the math right, if I solo mined BTC and had average luck, I could find a bit under 1 coin per month solo mining, or 25+ months per block.

Is that what you recommend?  Run for 2 years and hope I find a block, with nothing in between?

Seems to me that unless your spending thousands a month in electricity, pools are not really an option anymore (e.g.  "not an option, a necessity").



I think you did not get the point...
BTC is centralized more than ever, you are complaining about not getting your miners from a "legit" company like BITMAIN, the so called ROI's are shifting more and more over to more than a year with investments that are quite huge taking your monthly sallary into consideration just for getting a glimpse in a very volatile payment system that was thought for another purpose.
If you take a look at BTC at the value it is today, it probably would be smarter to buy BTC for the ammount you invested in your gear that is out over a month now and you are loosing value on your investment.
I did some maths, and my conclusion was to sell my gear and hold the ammount of BTC worth the gear, sit back, have a coup of tea and take a look at the value in one year from now.
The probability that i loose some of my holding in the event of BTC crashing back to $10 is less compared to the market value of my gear at the same event.

Well, if you do your maths, there will porbably pop up the same conclusion that occured to me with raising power costs etc....
If you want to mine, set up your own pool and go for it, that would be in the meaning of BTC along my comprehension.
I am not stressed with power costs, heat (which is good if you can use it to heat your home or your water), noise, failing hardware, not getting your hardware, your wifes complainment(naging) and so on.

Guys think about it. The fraction of home miners is currently a drop in the bucket compared to the raising "industry" at the moment speaking and please keep in mind, that the home miner is always served last with hardware that is one evolution, maybe two, steps behind of the development speaking of 0,06J hardware in use at the moment speaking.

I personally have no interest in beeing the dumb cash cow of the industry anymore.

Concluding i will turn my back on BTC and use other currencies based on another protocol than BTC to have truly secure, private and anonym possibilities to make my transactions besides FIAT  Roll Eyes

Indeed, it amazes me how many people still buy into mining hardware at crazy long ROI valuations/specs.

It is indeed easier to just buy whatever coin you desire and sit on it or trade etc than to mine it.

This is assuming you dont have free electricity and/or free hardware to mine with.

Yeah, well greed is one factor for this, the other is the habit  Roll Eyes
That´s what i try to tell people, but somehow it seems nobody is listening to it  Smiley
Nope i have either the first nor the second  Shocked Grin

Are you running them in your freezer?  Smiley

I was about to say the same thing.

Those temps are insanely low.

Maybe you're mining in the arctic?

Let me know if you have any questions,have been using them for over a year, they are free

Will do...

I will be checking out the links after my wife and son go to bed.  I'm still spending time with them this last day of the weekend.

What PSU are you running with? S7 needs a solid 12V, ideally 12.2V when under full load. If you have a multimeter check the voltage actually getting to the PCIE sockets.

Rich
I'm running a LEPA 1600W unit. Can't check the voltage right now but I'll check to see in the next day or so if it's getting at least a solid 12V.

Just checked it after four hours of running, turns out is started at about 4.3 TH/s, and ended up at around 1.3 TH/s before I rebooted it. I'm really going to have to figure this out, seems like a serious issue.

1600W LEPA is a piece of shit. (I have send it back to warranty 4 pieces of 6).

Use proper single rail PSU, not modular LEPA

I've run a pile of them myself but never had a problem, not a single RMA... Of course I balance the load across the rails and don't simply plug things a random set of plugs..  I wonder if it's the PSU or operator error...

I did however stop using them last year when I flipped to DPS-2000BB and IBM 2880W PSUs, would never turn back now and a much better value than the Bitmain PSU.

I've burnt a few of LEPA 1600's with 3 Neptune cubes @475 MHz across 3 rails (1200W total at the wall). It took about a year to happen and the strange thing was that they burnt out at around the same time. I also have a bunch connected to 2 cubes and they are still fine. I guess pushing 30A per rail is probably the limit for this PSU, though it is worse if more rails are at the limit.

Bitmain 1600 watt and a pair of corsair rm1000 both work well
Bitmain 1600 has a good price at $155
May be an rma
