You haven't seen my electricity bill or the load on my circuits...

i've cranked up everything I have to full power while rental prices are this much inflated.

Thanks, the values aren't really much below the recommended "slow" setting of 0.66V so I just set them all to that start/max and the fan to 40% and that seems fine. 1228GH @ 645W at the wall.

sorry been busy with westhash and nicehash pools.

Here is my lowest current miner.
these should work with fan on 40 and 50




you will be under 700 watts and hash about 1230-1250


all temps are 85      note the yellow freq  this means you are close to or at the minimum setting for the  loop .  so in my example  you can only lower the fourth loop and except to be able to get the miner to start

you probably already noticed that my hashrate dropped 24 hours ago from mmpool  

i just got another rental on my SP31 for 3 days on betarigs - 1.74BTC paid.

failovers

1.betarigs
2.nicehash
3.mmpool

 

ADD: the POW phase of that new shitcoin is expected to last til 20th.
I should be 10Btc up by the time it finishes if all goes well.

no just point your miners at nicehash and enjoy the 3x to 7x rental rate while it lasts. I got .67 btc in 25 hours.  my miners (7th) should earn about .1btc in that time frame.

+1 i've been waiting to see if Zvi would implement the extranonce.sub but I can't consider it for my SP-Tech miners from a nicehash branch that hasn't been fully tested.

No I'm testing the extronance fix cgminer that nice hash has posted. if you read my posts they sometimes have serious problems and since Nicehash posted a link I'm warning everyone what the problems are BEFORE they go try out the extronance bug fixed cgminer so they don't brick their SP20's. I'm picking up the SP20 tomorrow but I have some Antminer S3+'s on hand so I'm testing out nicehash's new cgminer build with the extronance bug fix in it. Better to break a $200 miner than a $799 miner. I'm testing to see if the latest flash or more importantly to us, the latest cgminer with the extronance fix for Nicehash is responsible for the "hashrate nosedive of death". I'm possibly breaking my cheap shit so you don't break your expensive shit. I know they are 2 different machines but the cgminer will be basically the same. If all goes well then I will test the SP20 with the new cgminer so you don't have to and tell you if it's worth it or not. Considering nicehash today was like 1100% above just bitcoin mining it may be worth the effort. But if you want to test the SP20 with the new extronance bug fix by all means go ahead, you would be doing us all a favour by testing it. Just post the results so we can have a look and be very careful. Backup the old flash build and the cgminer twice. Once on the machine and once locally. If you're unsure of what you're doing stop...I've seen alot of stuff break over the years from bad flashing and other screwups without the tech guy making a backup to re-flash. It's an $800 mistake if it goes wrong.

I'm hoping it's the latest build from Bitmain that's the culprit because if we can get the extronance bug quashed it's more money for us.

Wrong thread? Bitmain has nothing to do with the sp20.

Still testing but it looks like the latest flash from bitmain might be the culprit. Will advise. Still testing. If its the flash that's bad go ahead and someone try the sp20 on the new binary or I may do it. Just backup.

I think Phil posted them (settings at only 40 fan) here:
https://bitcointalksearch.org/topic/m.9808096

They do have a heck of a good team!  I really love their support.

If running at 40 percent I think you will need to under clock during summer for sure.   Not a bad thing since it does under clock well.

Thanks again to the spondoolies team who have now also donated an SP20 for continued cgminer support! 

As power and noise are bigger issues for me than getting the maximum hashrate, can people suggest reasonable settings to run one of these stable with the fan only at 40% in summer weather?

thank you for the info.  right now is not a good time to be playing with s-3's or sp20's  as the rates for rentals are very good.

K did a test with some of my Antminers. Still fucked. Goes fine until after a while the hashrate goes from 450Gh/s to 40 and sits there. Seems random when it happens only way to get it back is by re-connecting the miners. I'll try and let it go all night on one miner and see how long it takes(if ever) to recover as soon as the hashrate goes tits up. I've seen it go as long as an hour before going haywire. Speed seems the same when it's working so you're not losing or gaining there. Will keep you posted. I recommend you DO NOT upgrade to the extronance bug "fix" until it actually can be proven to work. I got a backup copy on my comp and the miner of the older non-fixed cgminer in case it goes badly.


I'm leaving one of my Antminers with the extronance fix on all night and will be seeing if it recovers, how long, or ever. It may be that the hashrate dumps because it's changing coins and instead of dropping altogether and just mining a new one right away it may be gradually reducing the hashrate then gradually ramping up on a new coin. Whether it's worth it or not who knows but I'll be watching.

edit: turned off the extronance with the new cgminer and it still does the hashrate nosedive of death. Trying to see if the latest flash from Bitmain or the new cgminer is the culprit.

It supposedly maximizes your hashrate by reducing drops when pools change to a new coin. But after extensive testing and tweaking with their recommended extronance.subscribe proxy(a month+). It fucks it up way more than it fixes. I'll take the bug instead of destroying up to %60 of my hashrate. When using it with my gridseeds it would slowly climb up the difficulty no matter what I set it at until it went "haywire" and would sometimes take up to 15 minutes to reconnect the miner to the pool. I know I timed it. I tested it for like a month as at that time nice hash had the best payout for scrypt. As for my Antminers they wouldn't even connect to the proxy without some serious tweaking and it would just suddenly dump the miner and it would start beeping and not connect. I would stay away from it like the plague. Keep the extronance bug unless spondoodles themselves put out a patch and even then I would hope they have a checkbox or it automatically switches back, so if it starts fucking up hardcore you can connect in the "traditional" way. I wouldn't touch it, but if you know what your doing you can see the pain for yourself. Bottomline it didn't work for me and alot of others, but like I said don't take my word for it, try it yourself. It's a good concept but unless the company themselves put out a firmware update, your playing with fire. In addition the whole concept of the proxy was to reduce disconnects and I constantly saw "Dropping connection blades1 on 192.168.1.150" then sometimes up to a few MINUTES(sometimes 15+ or never, having to reboot the miner to re-connect) later "Blades1 on 192.168.1.150 has subscribed" so basically it's not even accomplishing what the whole purpose of the extronance.subscribe bug quash in the first place which is to reduce disconnects, in fact it made them worse. Plus it was killing anywhere from 10-60%(WTF!) of my hashrate. It's retarded when the bug fix is WORSE than the "bug" itself.

If you're going to do this BACKUP THE EXISTING CGMINER FILE, twice. One on the miner and a local copy. Don't fool around. If you brick your unit or kill the cgminer on it you're screwed. Who knows it may actually work(it probably will)since it's not an external proxy, but someone else can test it and post. I'm not touching it unless spondoodles themselves either A. Issue an official firmware update with this "fix" or B. Sign off officially on this "fix" or C. Has been tested with a minimum of 10-20 people with a minimum of a weeks worth of testing with numbers to back up that it actually reduces drops or increases earnings without killing the hashrate.

Since I'm a comptech and "ok" at linux I may test it out for you guys. I'll see, don't want to piss 799 US down the drain. They have an Antminer S3+ binary so I'll dip my toe using it as a test on one of my S3+'s as it will only be on one of the miners I have. I'll post if it works on my Antminers which are alot cheaper.

What's with the extranonce thing? I'm not up to date with the news. What's the use of it?

We have prepared pre-compiled binaries for Spondoolies SP20 with cgminer 4.8 and extranonoce.subscribe patch (instructions included in README file):
Spondoolies-SP20-cgminer-4.8.0.zip (MD5 checksum: 727bbea1dbee633a7f36825a06596c3a)

This will give you optimal mining experience on NiceHash.com / WestHash.com

(btw: see also this thread: https://bitcointalksearch.org/topic/cgminer-extranoncesubscribe-extension-binaries-available-for-download-850620)

You'll get the AWB in the next 24 hours

How does SP20 shipping works?
I got "your item was shipped" note, but no shipment number to follow up.
Does the number comes in a later email?
For SP30 I got the airbill at the same time with shipment notification.
