That's what BitMain will recommend doing is taking off the heatsinks and reapplying the paste. I've got an undeperformer with a "-" asic, so I'll start there first. My temps are the same as yours and I only get 410 now.

We really need a bitmain FAQ. The same questions come up over and over bloating this thread.

It's past experience from the community and a strong desire to stop the scammers from taking advantage of new miners that we dose a huge amount of skepticism on any new asic mining manufacturer. We're all completely sick and tired of this which is why we all sigh when another one pops up, steals money, and delivers nothing.

Mining isn't a religion so people need to quit believing and hoping.

Gone from mine as well. Did you e-mail address did you get support from them? I need to ask them about a dead miner I have. Thanks!

got it - thanks for your input. If it wasn't worth their while or worth making money off of I don;t think they would have offered in the first place. There is obviously some business sense for them to be able to turn a profit selling kits or they wouldn't bother suggesting it at all.

S1, curious if anyone has done an RMA with Bitmain recently and what the best way to go about it is?

I had one of my S1s go belly up this morning. Won't power up. Anyone have any experience with a dead system under warranty with Bitmain? I submitted a ticket in their new support system, so hope it goes well.

FYI for those ppl using miners at work. I work in security and most security products are coming out with signatures looking for mining traffic. Most haven't zeroed in on tcp+stratum protocol and just look for http/https traffic heading to probably known sites, but it won't be long before they start looking for that as well since the specs are published. Just be careful and if you don't have explicit permission to use the device at your place of work then take it home.

Bitmain,

Could you let us know about the upgrade kits for S1s and S2s? When will these be available? I'd like to upgrade all of my S1s. Also, will the DC/DC component be fixed in these?

We get a lot of sunshine here in South Texas, so going solar is a total no brainer. 300 days of sun a year. My AC is driving the power expense way more than the miners, so I'm going to dig into your post and start contacting people in the next few months. Thank you again for posting that info.

I really appreciate the info on solar. We're going that route as well .

I'm totally in agreement with you. Sometimes when I post it doesn't come out right. Sorry, amigo. This whole thread is a scam. My guess is that it's the same account. I'm so sick of the scammers inundating us with crap like this. I really appreciate you posting the headers and warning us.

From OP "For those wondering, I am an independent hardware reviewer and not affiliated with Biostar in any way." That's fairly obvious from the mail header - Received: from emkei.cz (emkei.cz [46.167.245.72]).

You won't need the double quote now since you're just goig to change --queue 4096 with quue 1. What iu are doing is replacing this part at the end of the command:

--queue 4096

with

--queue 1

To see the line you want to change in the file out can just run a grep to see it:

grep "queue" /etc/init.d/cgminer

The output will show you the line out will modify with the used command. It will also show you that queue only shows up on that line.

So, to be clear this is what you want to enter if you are editing the file from default. Including backing up the original file:


Go to the web interface for the miner config and click save and apply. This will restart cgminer and it will reload the new config.

Freq 212.5 seems to be the most stable for these units. It'll give you around 430. Other people have cleaned out and reapplied the thermal paste, but I personally suspect its a power problem due to the DC/DC component not being robust enough to provide more power to the asics.

Bitmain, are you going to replace that component in later models?

Amen to that. Do NOT follow these other ASIC manufacturers and go that business model. We hate it with a passion. For you all look into a smaller form factor and look into either it fitting into a PC case or designing a complete system case pcu etc. Most manufacturers in this industry are doing this.

We're a mostly good community willing to help. I'm glad to see you all branching out into this space. I love your motherboards and have several systems running on them

I've found that the pair I have run best at 212.5 freq, --queue=1, hashing reliably for 2 days at 428. I'm fairly bummed that it won't reliably do more and won't be buying anymore until they fix the issues with the DC/DC converters.

428 now - we'll see tomorrow if that holds.

212.5 seems like the most stable freq for my set. He is negligible, temps are low as well 38C< on both.

Yes, I use it and I like it a lot. You can authorize a release and specify the location you want them to leave it.
