same problem as before   and I am using the address you sent the first one to me.

Hi zvisha,

Inline? Does that mean the watts must be the same for all 4 power inputs?

Thanks again 

Inline.

Some PSUs for SP20 need this:

I'm very happy with my SP20's performance with p2pool, it's steady and to spec. I do have a couple of questions though, if someone can help me out:

I want to experiment with the -queue setting, as from my experience p2pool likes this set to zero & reduces the DOA/stale rate. I presume that as there is no flag in the cgminer command already - it is using the default setting of 1? When I add the command "queue":"0" to cgminer via ssh & restart the miner, the queue flag is displayed on the cgminer pools page, but with no value stated underneath, instead of showing 0. Is this a bug, or am I unable to use the queue command on the SP20?

Also, on the asics stats page, am I correct in thinking that board 0 corresponds to loop 0, board 1 to loop 1, etc? I've noticed that loop 0 & 2 are running at a lower temp than loops 1 & 3 - so was wondering if I can increase the watts to those loops/boards via the settings page? Or do the watts have to be the same for all 4 boards (power units on the settings page)?

Thanks in advance 

SP20, can it be powered from more than 1 psu? like 2 psu/ blades?

I can't see there being many of these left soon. how many batches are you building of SP20 please?

You can try again, we solved the issue.

same here, finally was going to pull the trigger after talkin myself into it all day.. then wasnt able to

I can't seem to order an sp20E or 2 sp20E's  the cart tells me no shipping for my address. 

I purchased 1 last week and was looking to get 2 more. Any info on how get the shipping  to  work would help

You point it to first one and have the second as a backup. I was saying about 100 pages ago, changing the pools on the fly does not work with the present cgminer & SPT watchdog approach. As long as when you change the pool priority, the pool ID does not change, the SPT watchdog will restart the software if it detects connectivity with the 1st pool in the list.
Once restarted, cgminer will point again to the ID 0 pool, no matter what the priorities set on the fly are.

You probably will end up making a script to swap cgminer.conf files with different configurations (main pool + backup pool). A small PHP script placed and ran from /etc folder will suffice.
With it, you just rename the config file from your set (i.e. cgminer.btc or cgminer.ppc) into "cgminer.conf" and kill the cgminer process. The watchdog will do the rest.

Hint: if you need to cycle through various pools just call the script with cron .. it'll give you the possibility to mine for example 30% of your miner time for one pool, and the rest for another you can even use my eligius address for about 1% of the time LOL  



On the other hand, mining contacts will make BTC even more scarce and all the geeks who used to mine will cash out and start something else. I won't buy ever a contract, since for me, the whole fun is in setting up the hardware. If I get paid for it, is even better. I don't need to transfer money, so my real use of BTC is on Newegg or tigerdirect. Buying a miner or two with what I made a couple of years ago is another fun part. Heh .. there are more expensive hobbies For those who made a business out on the BTC landscape, I'm hoping you will do well without end-user owned miners in the future. Guys like jtoomim can use their setup for all kinds of hosting. The landscape its just transforming.

kind of.. hopefully

but in FACT when the fw was updated for LOWER temp stability, my SP3x became intolerant of previously acceptable HIGHER (35+) ambient temps.

which is a shame as my 4.7 TH SP30 is now a 4.1 TH SP30.

i have attempted to address this issue on a number of occasions but got ZERO response.

You can add multiple pools in the interface but it won't load-balance them just failover.

This would be ideal, though if you look at the high-end server hosting market as an analogy what you describe would not be considered cloud mining. For example, take a look at Rackspace. You can lease from them both cloud servers as well as dedicated servers, the latter which could include your own firewalls, storage, backup and IDS/IPS hardware. For dedicated you get to pick from a standard set of hardware, configuration, lease term, and the service level. They set it up for you and manage as little or as much as you need.

I can see this happening for mining. You make your choice and quantity of commodity mining hardware, select your pool configuration, pay your mining equipment lease, power and management fees, and you get to keep ALL mining profits. The only problem is whether anyone can offer this kind of service without adding too much additional cost.

Thanks Biffa ... I was hoping it wouldn't require having to "putty" in 

Its just cgminer so you have to edit the cgminer.conf file

You have to follow the instructions on that page:

I've been told there will be a December batch of Sp35

Otherwise look in the second hand market.

sorry to jump off the rail regarding the discussion ... though I must say this is the best company for miners, and this is one of the best forums I watch as well.

good points made by all, and at the end of the day we all have our own style ...  

my question is probably pretty silly, but how do you point the SP's to multiple pools in the "Pools" menu?

So ... I'm looking to buy another miner ... but the SP20 isn't powerful enough/suitable.

The SP35 for November delivery is out of stock, I've no idea if a December delivery batch will be produced (if it was, I'd guess it would already be 'on sale'). Therefore Sponds have no heavy hitting miners for sale right now ... or in the near future?

Are we entering a stagnation period where not much hardware is available before the next gen?

Just interested in fairly accurate time frames .. and yes 2015 will be a game changer .. I wonder what I will change into
