Ugh. 10 hours in and Ant1 fell to 411Gh at 218 and Ant2 fell below 400Gh as expected. I wish Bitmaintech would include an option to auto-restart in the firmware. Thinking about creating a small cronjob to do just that...
try setting them to 212.5 freq your dc to dc convertor gets too warm and your hash rate drops. Frankly anyone going above and beyond 212.5 on batches 1 to 3 is going to be sorry in about 6 weeks. If you want higher freq the 212.5 you will need a custom cooling solution for the dc to dc part. my guess would be a heat sink on it and a fan directly on it blowing air out of a hole drilled into the case. or set the freq to 212.5 still hoping to do a pencil mod with my next 2 coming in. These s-3's will be a world beater at freq 200 or 206.25 with a pencil mod under volt. maybe under .6 watts a hash say .58 watts Which part is the dc/dc converter? Can you label it in a picture? I have extra heatsinks and fans and a climate controlled server room. If there is a mod that can fix this (short of replacement) I should have the means to do it. I actually did this mod for all of my S1s and saw a 1GH inprovement across each unit. I have enough for one unit coming in on Monday so I'll go ahead and try it myself to verify. The part you are looking for are the eight grey square "blocks" above the heat sink. There were only four-per-blade on the S1 ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FRkuPkLy.jpg&t=665&c=d22XweeUsq6AKA) Cool. Thanks for that. I have some similar heatsinks to what you had in the pics from your other post left over from the old GPU mining days. Actually I still mine x11 with GPU's, I just don't have as many GPU's as I used to.

The S1 layout had caps in between preventing the use of a single large heat sink. I bet the larger surface area will work much better than the smaller individual heat sinks. Anyone know where to find something that will fit, and how to properly attach?

Same here. After a reboot, they start hashig to specs, the longer the run, the slower they get. Both on web Interface and pool. Not temperature related. Strangely sometimes i have to reboot them several times to get them working good. Seems i need to hit some sweet spot with reboot or they are slow. it is temp related but not asic chip temps . it is the r47 part above the asic chips that is getting too warm. and it is not measured . I would love someone with a to measure the r-47 part on and s-1 and then use a temp probe on the r-47 inside the case of an s-3 to give the temp my guess is the r47 part on s-1 is 2-5c cooler then the ones on the s-3

I'm just looking at this thread and bitmain site. And what i can see, quality went down the drain.i mean, quality in regards of delivery on time, process of any refunds, simple information to community.
Now it seems bitmain asking for btc in advance which is basically preorder. With s1 there was no issues related to delivery of miners. Now im reading people waiting to get their s3 mining week or more! I was hesitating to order B1,B2,B3 and it seems i didnt lost a lot. as all batches was delayed and now batch 4 and 5 is simple proeorder with no warranty that will be delivered in time frame given.
I dont know whats the issue is but even labeling boxes as miner means issues for end user. I am fan of bitmain but at this stage whats the point of ordering when their are not in stock?
Price is nice but again waiting time for B5 will kill any profit if any. We looking at least 14 days to receive any miner. What if customs will delay the process? Whats safe quantity to order? I was thinking to order 10. Any ideas how this will look for customs?
no miner is for sale at a better price and faster delivery. have they slipped from the s-1 yeah just a bit. down the drain no. down the drain would be what knc did from the early jupiter last nov to this years neptune. Based on all that i can see and read. these s-3's are better then the s-2's but not quite as good as the s-1's. By that I mean all aspects of the miner. I order 4 so far I have 2 hashing 2 on the way. when they come I will order 2 more. after those 2 come I will assess my next move. right now the mining game is very tough. Maybe i was to harhs to say down the drain. But i compering s1 to s3 situation. And thought maybe they will do same what they done with s1. I bought abut 20+ s1 with sushi and bitmain and never had any issues. I still think mining is something which will make few BTC before is not profitable anymore but for small people like me is getting more difficult and will not be easier. 10 units will make roughly 3 BTC a month. As for the wait time - keep in mind that when the S1 came out Bitmain was an unknown and demand built up gradually over a period of weeks. But the S3 was highly anticipated and demand has been through the roof right from the start. No matter how many get ordered, there is a point where any company will limit the how many they produce in a batch. As time goes on I think you will see this demand and supply issue smooth out. On another point - you sound very whiny. You probably should get out of mining.

No errors on the asics but have to restart a few times at stock frequencies to get anything above 400gh. I've seen behavior like this with Coincraft blade chips missing cores upon cgminer restart, but they added the HW clear flag to fight that.

I can check our old stocks and find some perfectly straight/flat heat sinks from old server video cards. I have some dual-head Quadros in mind that I might be able to cut up easily. Either way won't be able to test until Monday. My fiancée will kill me if I head back in this weekend. Definitely not on call. Anyone know a good source for 3M thermal adhesive strips?

Yes, I noticed that sometimes they go down, but not on all machines. i have one that is very steady at ~441 at default. Question: did someone tried to put heatsinks on R47 DC-DC converter? Was it effective? Where do you buy them?

I have a problem. My "Authorized Distributor" has done the following.
I (stupidly) agreed to overpay on batch 1 S3 because I wanted a batch 1. They usually make money especially batch 1 where you have good clarity on what difficulty might be when they ship. I paid very early on July 1.
I received my confirmation emails. I re-checked my account after end of business later that day. So far everything was in order. Batch 1 S3 etc.
2 weeks about go by and I pop in to check my account to find out when my Batch 1 order will ship to discover it's a magical Batch 2. I have no idea when it was ordered, what point in the queue it was at or anything. At this point I have received 0 contact from distributor. Order was altered 25.5 hours after I placed it. I wish I had known I needed to babysit this order to keep things on track and at a price I could live with.
I notice in my account there is ask us a question. So I ask if they can fix my Batch 1 order to actually be a Batch 1. I really wasn't thinking that someone intentionally changed anything but that there was a clerical error.
24 hours pass still no contact from distributor.
I send a message to the person who has their email on my receipt (I dug it up just to ask again). I was not nice about it. Reply was received in 3 hours. Nothing too helpful just an offer for fair compensation. What is fair for bumping me into a cheaper batch, failing to ask me about changing my order, failing to ask about re-pricing my order? At this point I didn't want a batch 2. I never wanted a batch 2. I asked within 3 hours for the following, after apologizing, What my total refund would be AND what my "Fair Compensation" would be.
Within 12 hours the disputed order shipped.
No answer Friday, Saturday, Sunday, Monday or Tuesday. Email was sent late Thursday. As of Monday late my order finally finished its warehousing. Tuesday I send another email asking if distributor would please reply to my last email. Last email included in current email.
Wednesday I get a reply. Here is your tracking #. Batch 1 and 2 shipped about the same time. I have to refund the 7.7% for specs and I have to refund 0.02 for the price difference. Let me know wallet address.
I reply I asked for full refund and fair compensation. Order is complete when package is accepted I have not and in 7 days UPS will return your package to you. I point out I still wouldn't have paid shipping on Batch 2 (ordering from bitmain) and told distributor I figured the 0.1115 over the cost of batch 2 directly was fair compensation at this point. I notified distributor that I was interested in either 0.1115 or a full refund and they have until the package goes back at that point I expect a full refund.
No reply in 48 hours. Send email to admin because I get an order complete email. I point out 1.48 is better then 0. Ask what they would prefer.
48 hours more still no replies.
I really would like a way to deal with this that doesn't leave me with a more then Batch 1 priced shipped same as batch 3 held in China for 4-5 days batch 2 then left at UPS because I have an issue with the questionable way this has been handled. Most of this is the price of business

1. Why did you not order directly from bitmain? 2. If you paid with paypal or a credit card you can file a dispute directly with them. Although, filing a dispute due to "shipping time" might be a hard case to win. "Batch 1" and "Batch 2" are identical products. 3. If you paid with BTC you are SOL 4. Best thing to do is identify them in the forum as a warning to others. The bad publicity might make them act.

Has anyone tried running the units uncovered, S1 style? Im guessing the only reason the cover exists is to protect the front heat sink and allow air from the fan to stay within that small space. Since the control board sits on top, and the fans never even seem to come close to max RPM, I'm thinking the units might still operate well without the cover. In fact, without the cover they look very similar in design to the new Rockbox blade miners which only use one push fan. http://minersource.net/products/r3-box-450-480gh-bitcoin-miner-in-stock-nowGranted these are ASICminer chip, I feel like this might allow the DC/DC modules to at least breathe. EDIT: I dont have access to my S3s until Monday, so I can't try any of this yet...

I was able to get the discarded amount lowered as well as the load. I changed the queue to 0 from 4096 and added --scan-time 1 --expiry 1 to the cgminer file. ***IF YOU ARE NOT SURE WHAT THIS MEANS DO NOT TRY AS YOU WILL BRICK YOUR UNIT*** This is the first attempt, not sure if 0 is the optimal queue value for all pools but if you are a P2P miner you may want to try this out.

I was able to get the discarded amount lowered as well as the load. I changed the queue to 0 from 4096 and added --scan-time 1 --expiry 1 to the cgminer file. ***IF YOU ARE NOT SURE WHAT THIS MEANS DO NOT TRY AS YOU WILL BRICK YOUR UNIT*** This is the first attempt, not sure if 0 is the optimal queue value for all pools but if you are a P2P miner you may want to try this out.

I don't want to speak on Duce's behalf, but experience seems to show at this point that there is possible detriment to changing the queue value from 4096. BMT seems to have done this for a reason. I am seeing no difference in performance using modified expiry and scan-time settings. I'm working with about 36-hours worth of data at this point.

Nope. Too impatient. Heading to the office to try and run them naked. I think having this DC/DC modules couped up without a heatsink is no good. I'm heading out for the day afterwards so I'll report back when I have useful data and/or warnings.

I use windown and putty And lowering the discarded will benefit what?

Yeah, as much as I want to overclock these guys, I don't really want to pioneer it. That and I don't really have spare 2x 6 pcie cords to shove into my psus, though I'm sure I could buy them. Mine all run between 430-450. I have one that seems to dip to 410 every once and a while, im not sure why, but for the most part stable. The way I look it is, we are getting MORE than double the hashpower for the same power usage. As a casual at home miner, that's good enough for me. Hell, I might even buy some of their USB units when they come out ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)
