great, thanks dogie!


thanks digitalmocking

somewhere buried deep in this forum is the answer to my question. unfortunately, i cannot find the answer so i a reposting it. sorry

what are the hardware error thresholds for this miner? i am at 657 hardware errors for 17 hours of work, that is about .0038%. i think anything around .02 is a concern but i cannot remember. dose anyone know?

thanks

Hey Dogie,

Can you put on your guide hardware error tolerances. I've done some adjustments and have been seeing errors in the .0045 percent range. I know before you told me what the limit was for concern but it is buried deep in another thread. I think this tolerance would be helpful for some.

Thanks!

Ok, great!!! so my s5 never shows that i am dipping below 1Th/s but in the pool, for 30m it shows 977.5 Gh/s. everything else according to the pool seems to match up.

here is my pool
http://eddiesilva.me/wp-content/uploads/2015/03/poolhash.png

and here is my current hash
http://eddiesilva.me/wp-content/uploads/2015/03/updateantminer.png

So why the difference?

sometimes the 5s hash does drop and sometimes it does rise, I think it has to do with the psu but I'm not sure. The average stays about the same so I know the miner is working at about 1.1Th/s which is where I want it with my current setup. I could always do more hashing but it doesn't seem as stable when it is not at this setting.

As an average as you stated dogie, I should be watching the daily hash on my pool and miner settings and now worry about the 5s and 30m, 10m on the pool?

I seem to be getting consistent payout, i guess that is all that matters.

I have modded my fan setup, Noctua NF-F12 2,000 pwm push and an arctic 1500 pwm for pull. room ambient temps are about 24c during the day and 19c during the night

I've been trying to find an explanation as to how to read the cgminer screen that I posted and what values I'm supposed to be shooting for. This setting is the most stable (HW at .0003%), which is good, I think and not over .02 which is bad? Utility is miner efficiency? According to various articles i foung on google (they were all GPU based machines) utility needs to be high. On slush's pool its 20, antPool is what you see.

I guess what I'm really asking about is if my screen looks good and where do i need to make improvements? 

Now that I have fan noise to a level acceptable to the family, the heat generated is raising the temp of my upstairs hallway 4 degrees. So I'm asking...

Where do you keep your miners and could one mo er set at 331mHz pump out enough heat to raise the temp of an open floor second story 4degrees?

In my endless efforts to keep the s5 cool and quiet running near default speeds, I have opted for Noctua and Arctic cool fans. Those fans that you posted are not that quiet. The 35db is not that quiet. Unless they are PWM fans, they will be running at full speed. What you are looking for in a cooling fan for the s5 is one that directs more of the airflow forward than just spinning fast. The Noctua fans are designed to push air in a more forward direction. I have tested this and it is true. My Noctua fan on the front pushing air in is a Noctua industrial 2000rpm PWM fan. It is currently spinning at 1680rpm and an Arctic F12 PWM fan running at 1200rpm. Combined with the miner set at 325 they are making 44db in sound. Temps are 60 and 62c with 17 hardware errors over a four day period, ambient temps in the 20-25c range.

I tested a higher cfm fan at the same settings as my push fan with the temps running into 65-70. I also had to add a fan to the rear of the miner to push hot air away from the miner, one fan on the side of the miner to push air into the top of the miner (my miner sits on its side) and one fan on the bottom pulling air away.

So you see, long story short... It is the design of the fan and how the fan pushes the air that makes the biggest difference. If I disrupt the airflow of the Noctua my temps will go up and the Noctua will spin faster. With that said, I recommend the http://www.amazon.com/gp/product/B00KFCR5BA/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 and the http://www.amazon.com/gp/product/B00H3T1KBE/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1

I thought it was a misread too but the speeds of the fan DOES increase then decrease and the software does report the changes. I'm not sure why it's performing like this, the noctua fans are designed to push air more streamline. I thought that could be it. Whatever it is it's working and my house is quiet. With another fan speeds were in the 3000's and loud at this setting and temps were 5 degrees higher. It didn't make sense until I put my hand under the miner and with that setup there was a lot of air escaping from under the miner and not making it back to the heatsink. With the noctua fan there is no air escaping from the bottom side of the miner (my miner sits on its side) and if I put an accessory fan to pull or push from the bottom side temps go up and the noctua spins faster.

The 1200 rpm fan is capped at 1500 rpms, the noctua fan is at 1680 rpms.

So in my ever epic request to make this thing quite.... I think I finally have found a way.....

http://eddiesilva.me/wp-content/uploads/2015/02/antminerweb.png

Here is the antminer page running for 8 hours overnight. Ambient temps are 68F or just below 20c. I have a Noctua SSO2 Bearing, Retail Cooling NF-F12 iPPC 2000 PWM fan attached as the push fan and an ARCTIC F12 PWM Rev. 2 Fluid Dynamic Bearing Case Fan, 120mm PWM Speed Control, 74CFM at 22.5dBA as the pull fan. And that is it, nothing else.

As far as quite goes, it is waaayyyyy more quiet than stock and more quiet than any other combination of fans that I have tried.  The miner is running a bit hot, 61 and 59c but I am perfectly stable at 325. I do not plan to overclock the miner, maybe Ill try to bring it up to default but as of right now, Im happy with the noise and hashrate.

This is my S5 with a dust cover on it. its not the one that wraps around the fan but sticks on the front of the fan. Seems like it does a decent job. But really, how do you guys deal with dust? do you clean the miners out once a month or some other schedule? Doesn't dust contribute to increased heat?

Thanks... I'll try that!!!

Yea. I can show you a pic but first tell me how to upload a pic. It's been a while and I can't seem to find a help file.

Does anyone use a dust filter on their s5? I have one on the push fan. It contributes a bit to the noise but what do you all do with dust?

When I make the can switch I'm not going to be at 1.1Th/s but I would like to be close. I'll be watching the temps and if I'm stable and I can run the miner in the 60's then I could get a few more hashed out of it.

1) What power supply make and model are you running?
2) Are you seeing the varying hashrate on the S5's status page or your pool's status page?
3) What pool is it at?
4) Please can you provide a screenshot of the S5's status page?

Temps are best kept under 60C but its not a "its going to blow up" situation if below 70C. You may shorten the lifetime of your S5 by running it that hot however. Hardware errors shouldn't change appreciably between 60 or 70C either.

I am using a EVGA SuperNOVA 650G1 650W ATX12V Power Supply 120-G1-0650-XR power supply
I am seeing varying hash rates on both the status page and the pool's page. I know they are not going to be exact but the pool shows a dip in my hash rate, the hash rate graph on slush's pool (the one I'm using) looks like a saw blade rather than a straight line. The miner is set a 337.5 and that should give me 1.1Th/s but it sometimes dips to just under 1Th/s then back up.
Im using slush's pool with btcguild as a secondary

sorry, its been a while... how do i post a screenshot? i have it in png format

Ambient temps are about 71F. Not sure the c conversion. It's not summer where I am but it's not super cold and the floor where the miner is never dips below 71F and sometimes it goes to 76F but not lately. Another complaint from the fam, upstairs is too warm. But now that is 71F I think it will be just fine. We like to live around 72F anyways.

I think I found my limit. I have an s5 running 337.5 with only 4 hw for 24hr period. It's hashing at 1.1Th/s but sometimes it dips to just under 1Th/s. Why is that? Is it due to power irregularity? Also, at these settings to he temps are 66 and 68. I know that is high for the miner but I'm not getting hw errors. So I think this is stable. But the temps. I keep reading that the miner needs to be below 60. Is that due to instability and hardware errors. I once thought heat was related to hardware errors but with this discovery it is inconclusive. So, all you really knowledgeable people out there, is is safe to rum at or below 68c? I have a push pull fan system and have replaced the stock fan. It's not quiet, in fact, I have to make another fan changeout before the week is over. This fan setup is too loud for the fam.

When I make the can switch I'm not going to be at 1.1Th/s but I would like to be close. I'll be watching the temps and if I'm stable and I can run the miner in the 60's then I could get a few more hashed out of it.

I thought about a higher PSU but I couldn't afford the higher psu and well, i didn't plan on overclocking the miner either so I just went with a supply that meet the miners needs, 4 VGA and at least 600 watts. So how to you calculate hardware errors in percentage? so I can make sure my miner does not go over a certain percentage.

Call me worried but, I think I have found a setting that gets me a decent hash rate with temps below 60c. 300 with the current set up that I have will yield 59 and 57 degrees on the blades but within the first hour or so I get 1 hardware error and over the course of a day and a half (36hours) I have 12 hardware errors. Now, I am powering this miner with a high quality 80 gold 650watt power supply.

first of all, are 12 hardware errors over the course of 36 hours ok for the miner? does that seem a bit high? I suppose the cooler I get the less likely the hardware errors will be produced. I am getting two new noctua nf-f12 fans, one at 3000rpm (push) and one at 2000rpm (pull) to replace my current setup as the wife has finally said the miner it too loud and producing too much heat.

I am asking about hardware errors again because I noticed that when I first set the miner to 300 it performed at just over 1Th/s and now it is working at just under 1Th/s. Do hardware errors effect hash rate?

I'm wondering where to mine too. I just got an antminer s5 and I was using BTCGuild and with regular payout. Now it's taking hours to be paid. Yesterday it took 12 hours to be paid .001 btc. I'm looking for a pool that pays for work done. I understand about luck but why did I all of a sudden go from regular payouts with my antminer u3 to long interval payouts with my s5?

I know I might be asking for unicorns or flying pigs but are there pools that pay out more consistently? I'm trying to figure out all this payout stuff, BTCGuild is a pplns, which seems fine until you don't get paid for a while. Like 12 hours.
