As it says on the Pools page to change the template, ssh in to your miner and do the edit using:

Assuming it's still available, I'll take the +3.51% to +3.75% slot.

This is sort of an interesting change, though I'm not sure I like it. It feels more constricting since I can't select the number I like because it's in a range taken by someone else, so a speedy reply is more of a factor now than it was before. Posting another guess as the closing date draws closer is also limited, since it's likely the range will already be taken.

Probably both. Sales of S5 will likely resume, and they'll also likely release S2 upgrades, possibly with a full S6 not too far behind it.

yep, i can confirm this! got the compensation and now just waiting for the new units to be spun up now. instils a lot of confidence and trust the way this was sorted out once the problem was discovered.

[edit] checked this morning and the new miners are now online. thanks lee.

I just finished setting up my new SP20 Nano farm up in the basement.

I used a d-link DIR-615 with dd-wrt installed to make a client bridge and hooked all the SP20's up with ethernet from the router.



Downloaded firmware 2.6.14, set voltages to 0.62 startup and 0.636 max.

Getting about 1125GH/s per unit at ~590W. Running 2 on a 1300W PSU and the other on a 1000W PSU. Fan speed at 20% seems to keep all ASICs at 85c and exit temps at 60c for the top shelf unit. You can't even really hear them at all upstairs unless you stand by the stairway.

Definitely pleased with this purchase!

I have seen many user in this forum including me that dont have the skill or the time to learn using these miners without a controller and go into the time wasting story to test different things and specially drivers usb connection cables etc.(someone will say ok but you learn thrue this)
so how much more will be to be build with a controller inside and all the trimming and tuning to be done with software??? with a single ethernet cable???
they build this kind of excellent hardware and they dont put the controller.
its like selling a car without a wheels...
there must be a reason except cost I believe but can find out what it is..

I don't think there will be very much room for changes. There are too few spots available within a reasonable range for it to make sense for someone to give up their spot.

My guess is -3.26% to - 4.00%

You are right. They are relatively cheap... MARS MP700, i though they were going be more than enough but...

I have 3x SP20 Jackson and I found that if I increase w more than 100 the PSU goes off... I should have been able to set the PSU to 280 to exploit the full potential. However, if I was lucky enough to have a good PSU, cables would not have lasted more than 1 week...

 

I think the price of bitcoin is determined by the market, not by the cost of producing it.

When bitcoin hit $1200 it wasn't because the cost of producing it increased, it was market forces.

The cost of producing bitcoin is raised or lowered to meet the market price, not the other way around. If bitcoin goes up to $1000, miners will see a profit incentive and more rigs will come online... driving up the mining difficulty and hence the cost of producing each bitcoin. If bitcoin goes down, some miners will switch off unprofitable rigs, reducing the cost of producing bitcoin (for the remaining miners). Mining expands or contracts to maintain an equilibrium where the profit from mining is marginal, whatever the market price is.

Miners are reacting to the market price, not the other way around. Very few people buying bitcoin would perform a calculation to see how much it would cost to mine bitcoin (i.e. what the production cost is), instead they look at the current market price.

+6.51 to +6.7 please as my  guess

philipma1957, I've got more thoughts about pool strategy. I guess I'll continue the conversation here, unless you think we should create a separate pool strategy thread.

I've had fun with the above pool strategy, but it's been a bit harrowing being primarily on a high variance pool. If it wasn't for that fairly recent string of insane luck on kano.is, I'm not sure if I'd be ahead.

I know that everyone says that variance doesn't matter, long term. But if you're gunning for a short term ROI (relatively speaking), it seems like low variance is critical as difficulty goes up.

As the difficulty was floundering up until recently, I haven't stressed too much about variance and have been playing on smaller pools. But now I'm 80 days in with my SP20 and about 75% of ROI, and the difficulty seems to be rallying a bit. So rather than gambling on smaller pools, I'm thinking of going the conservative route of low variance until I hit ROI. The problem is that I don't like contributing to the dominance of larger pools.

So here's what I'm thinking. I'll set NiceHash/WestHash as the primary, but with a low profitability threshold. I'm thinking about 1% over nominal BTC/THs/Day. With a 2% NiceHash fee, basically this means I'm agreeing to lose 1% over nominal to mine there, which seems fair. Then I'll set up f2pool.com as the secondary.

The idea here is that as long as NiceHash is doing slightly better than nominal BTC, I'll mostly be mining there. This way I'll capture nominal profits as well as any upticks. And when NiceHash is in the dumps, the miner will revert to f2pool.com. Sure f2pool.com has high fees, but if it pays for every submit that means that the fees are the only cost of frequent bouncing between NiceHash and f2pool.com.

I'm hoping that by mostly mining on a rental site, I'm effectively contributing to decentralization (hopefully), while enjoying lowering variance.

How does this strategy sound to you?

Hmm my guess 5.21 to 5.50

Also philpma add deadlines for enteries ?

One needs to be corrected.



tss               has          +4.80 to +5.05    this need a correction 

as both +4.76 to +5.00 and +5.01 to +5.25

have been picked before you picked.  maybe +5.26 to +5.50?

Anybody know gauge the cables are for EVGA G2 power supplies? They are red, and sleeved, with nothing to indicate 18AGW or 16AWG. This seems to be a risk associated with use of the PCIe standard way beyond it's original intent.
