2021  Bitcoin / Hardware / Re: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.25/GH & 0.51W/GH on: March 15, 2015, 10:04:19 AM
They are sitting on a flat surface already. I guess I can try taping the bottom and top heatsinks and see what happens. I do like to keep them running at 60 or below, since we really don't know the real temp of the ASIC chips. Do you know the max temps of the ASIC chips on there? The sustained temp?

S5s are happy up to about 70-72, then personally I get a bit iffy. If the safety cutoff (with plenty of in built margin) is 80C, then we should not have a problem at 70C.


Anyone know the model of the stock S5 fan? Also, do they make a PWM adapter that goes between the fan and connection to undervolt/clock the fan a little? The fan is working too hard, temps are 49-50, I could lower the RPMs a little to get it a little quieter. Also, how many watts/amps/volts can we pull from the fan connections on the controller board? The fan on there must be pulling like 4-5 watts, right?

I've asked for the spec sheet but unable to get anything out, the last one I saw didn't have a name on it. What I do know is that the stock fan uses 1A+ so there's plenty of capacity. I've asked again. Edit: Parameters are here: https://i.imgur.com/fvqHojq.png. Note the rated current (max) is at 4400 RPM and 8V, so its more likely around 1.2A at 12V at 4000 RPM.


you can change the subject line at least temporarily Smiley

A better solution would be they lower the price back down.

Requested it be changed, I'll check back on it in a few days if its not moved. Edit: Its changed.
2022  Bitcoin / Hardware / Re: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.25/GH & 0.51W/GH on: March 15, 2015, 10:03:36 AM

I emailed them about buying 50-100 units when they reopened sales at $320. By the time they got back to me it was $419 and I was told there was no discount for 100-unit sales. I checked back when they dropped the price to $369 and was still told that there was no discount for 100-unit sales. Since the 1600-unit mass purchase is priced at about $350 per unit, they're probably not in the mood to negotiate. Which is retarded because in 3 months 1.1TH at $350 is gonna cost quite a bit more than 1.1TH at $370 now especially when you factor in opportunity cost of not mining for 3 months.

ANTMINER S5 BATCH 6 - Large Buy Reservation
Speed:    1600*1155GH/s
Price:       283392 USD

283392 : 1600=177,12 USD + shipping

Listed price for Batch 6 is the 50% of full payment as deposit to reserve the stocks. The remaining amount must be paid before May 9.

So yeah, $177.12 is the half-down deposit. The full price is $354, a whopping $15 off list price (4% discount). What was their unit price discount on the 52-unit blocks they were selling in February, when we first tried to contact them and got no response?

The point of Batch 6 is more of a reservation than a discount. There are several parties that want large quantities - but not for a few months - and so this allows Bitmain to plan production. The last thing anyone wants is for no S5s to be available because a few big parties came and took several weeks of production without any planning, and miners not be available to anyone else.

They have S5 now at $369 for March 30 release. Shocked
Yeah, I just emailed their support people (Janet and Yoshi) for a BTC refund since they dropped the price the day following my BTC payment for two!

Please don't email Yoshi for order related enquries, he is no longer at that level and is very busy. Email email Janet, bitmain, use the ticket system on your account or ZenDesk.


What is the minimum difficulty I should set for these?

512 absolute minimum, 1024 much better, 2048 also acceptable.

Why are you running your S2 topless? Mine always ran hot when I did that. Also, why is it blasting directly at a wall? Tongue
2025  Bitcoin / Hardware / Re: [Guide] Dogie's Comprehensive Bitmain Antminer S5 Setup [HD] on: March 15, 2015, 09:45:47 AM
Is there a recommended fan which can easily replace the original fan to reduce noise?

Corsair sp120 high performance + af120 silent for a small test i made was very silent but i don't know how it will work for many hours or if they will be any problems for the s5 as i didnt buy the cable to connect them to psu yet..From my search i think this is the best solution but you can try it in my opinion with 2 sp120 as they are more powerful but silent too, i think it will be much better.

rpm for sp120 and af120 it will be around 3.360

Kind Regards,
BTC-Bank.

AF120 is 1650RPM with moderate static pressure, which is too low for an S5. 2 SP120s works in sensible ambients and benefits from taping the heatsinks closed (top and bottom). Its going to run hotter than stock (60-65) but thats fine and its the closest you can get to a silent S5.


Thanks for this.

No problem, let us know if you need any help.
2026  Economy / Service Announcements / Re: Avalon4 with global shipping can be purchased here! on: March 15, 2015, 09:43:25 AM
I made a microcard for the quad core new faster pi.  the card works fine for the old slower model B.  it does not work for the quad core rasp pi. So until I get an image for the quad core rasp pi  I advise anyone looking to run these to have a model b on hand.  no one has shown me a working model b plus or a working model 2 b quad core..

I didn't think they worked together but didn't want to say anything as I wasn't sure. I was really disappointed to find out that they didn't make them even remotely backwards compatible because it defaults the whole purpose of having "1" platform everyone works from. Now everyone has to start again and support TWO platforms, its silly.
2027  Economy / Service Announcements / Re: Deep In The Mines Cryptocurreny Mining Hardware on: March 15, 2015, 09:41:45 AM
I agree. But as long as you ship the item and use signature conformation Paypal and Ebay have decent seller protection. So we are not too much worried about that.

The usual method is that they'll mine on it for 30 days, then force a return. There is almost no way for a seller to prevent a forced return via Paypal, so you refund them in full and lose out on the depreciation of the miner.
2028  Bitcoin / Hardware / Re: Strange S5 Occurances - Solve it get a btc reward on: March 15, 2015, 09:39:28 AM
Hi fellow miner, The problem is mining with nicehash/westhash.  when they switch to low diff coins, the antminer s5 goes crazy and goes haywire.  hash rates go down, funny things happen. Try other pool such as antpool (well, not at the moment its down), and see your results.  give it a try!  I don't mine on westhash anymore, the s5 had too many problems.

ヽ༼◕ل͜◕༽ノ

That is a very good point, although I would have expected the controller to flip out by locking up.
2029  Bitcoin / Hardware / Re: Are all SP20s the same? on: March 15, 2015, 09:30:29 AM
Dawson would be an SP10, so probably a typo.

I think the E signifies that the mounting of the hash boards was improved for better durability during shipping.

That's correct, "SP20 Dawson" is not a thing and is an error. And the "e" is to signify they fixed the hashboard mounting but very few people use that moniker.
2030  Bitcoin / Hardware / Re: Low power chips WANTED!!! 0.3 W/Ghs or around. Ideal miner design for exchange on: March 15, 2015, 09:28:08 AM
The only viable way this could change would be massive amounts of small devices integrated into home electronics.

I've heard you talk about this web of things type model before, it will never ever ever be even remotely close to viable. Putting single / quad chip PCBs + own controllers + wifi is so incredibly expensive compared to even an S5 formfactor.
2031  Bitcoin / Hardware / Re: [Guide] Dogie's Comprehensive Bitmain Antminer U3 Setup [HD] on: March 15, 2015, 09:24:48 AM
USB hub received, I hooked it up to my power supply, plugged in one U3 and it worked just fine.  Plugged in the second and ERROR.  Quit and restarted with them both plugged, more ERROR.  They both hash together at about 30gh each (down from 59 alone), but with constants errors as below.  So what else could it be?  (I unplugged one USB toward the bottom, I think that's what the last 3 lines are starting to show)

Is that a powered USB hub?
2032  Bitcoin / Hardware / Re: [Guide] Dogie's Comprehensive SpondooliesTech SP30 Setup [HD] on: March 15, 2015, 09:24:00 AM
My 3 questions:
1) My SP30 is mining @4.5Th/s turbo mode, 3100Watts on the wall. After changing the overclocking settings from "turbo fans, highest rate" to "medium fans, high rate", mining speed and wattage remains the same! Is this normal?
2) In my miner's firmware upgrade page, it says
Code:
Current firmware version: 2.5.64
Latest available firmware version:
So it does not display information for latest firmware. Anyone know what version is the latest and where to find it, since my miner can't? (dont know why)
3) Should I open the miner case and use vacuum cleaner to clean up the dirt?

1) Doesn't sound right, it should underclock.
2) I can't remember if firmware versions remained constant, if so then 2.6.14 or so is the latest stable. You can email them to get a manual file.
3) You're not going to have much buildup in an SP30 but you can if you want.

Ok I successfully upgraded to firmware version 2.6.14 (for some reason it was not displayed). I selected medium settings, I was getting around 4.45Th/s, slightly lower that turbo mode, around 3kW on the wall.
I feel that one should prefer medium settings over turbo mode, it doesn't push the ASICs/PSUs to the limits and will make the miner last longer. 50Gh/s is not much after all now.

Still doesn't sound like its changing sufficiently, medium settings should be quite a way from turbo. Can you upload some screenshots?

This guy is claiming its a S3++ A s3 with S5 chips
Is this a scammer or something?


The S3++ is a real thing that is/was sold in mainland CN only. I can't verify the legitimacy of that particular listing however.
2034  Other / Meta / Re: CanaryInTheMine is further abusing the trust system on: March 15, 2015, 09:15:50 AM
Gladly, theymos added a 'tidle' option to trust list and it is really useful.

Which CITM is now also abusing *sigh*
2035  Other / Meta / Re: CanaryInTheMine is further abusing the trust system on: March 14, 2015, 07:45:17 PM
That is a huge trust list...mine is 13 total (counting default and old scammer tag). I think it would probably be wise for him to look through the list and trim it down.

It is insane, I'm going to post it in full just to demonstrate how silly it is. It is one solution but in the previous thread he was asked to do so and and ignored it. It would remove his own trust at the same time.

How many people have you left negative trust for that you've never carried out actual deals with, but rather do not like the way they conduct themselves on this forum?

You mean the people committing illegal acts and telling me to kill myself? That openly operate using shill accounts and refuse to reveal their main accounts? I am also NOT at trust level 1, nor do I have 180+ people in my trust list simply because they gave me positive trust.
2037  Other / Meta / CanaryInTheMine is further abusing the trust system [Fixed] on: March 14, 2015, 05:48:27 PM
CanaryInTheMine has previously come under fire for misusing his level 1 DefaultTrust position by adding users into his trust list in return for leaving him positive trust. This further increased Canary's own trust score and power, as well as the addition of many accounts added inappropriately to DefaultTrust. This included newbies, those abusing their level 2 trust and others running questionable operations. He has refused to chance his practises and is further now abusing that self given power at the detriment of the forums. When you put some numbers on the trust network, its pretty shocking case of abuse and centralisation of influence.

There are currently 417 accounts in DefaultTrust lists, of which 211 (53%) are from Canary.
181 (100%) of people who left Canary 'trusted' trust are in DefaultTrust because Canary added them to it
(+ some overlapers).

What is more, he has started abusing his inappropriately self appointed power. He has ~trusted several accounts, including me, aggressively in order to inappropriately shield his own interests. CITM is heavily involved with ASICMiner.

AirWolf - because he put a bounty on information regarding ASICMiner (to regain his investment)
Silverspoon - because he was critical of ASICMiner
SpanishSoldier - because he was critical of ASICMiner
NotLambchop - because he was critical of ASICMiner (although he is a bit hash)

And... me. CITM has refused to respond as to why he has ~'ed me and does not respond to PMs. Its one thing to buff his own ratings, but he is now directly inhibiting the very reason for default trust's existence for his own personal gain. There are currently 10 phising accounts, scam accounts or PM spammers that I am the only trust rating for, which are now unmarked.


Canary should either be forced to alter his negative practises or face removal from DefaultTrust.




Edit:
Canary has repeatedly dodged explaining why he has removed me from DefaultTrust, and refuses to be accountable for his actions. He has since left a negative trust rating for creating this thread and highlighting his abuse of the DefaultTrust system. These are the actions of a desperate man, not one fit to be in DefaultTrust.

I absolutely do not trust dogie. No personal btc were risked, I simply do not trust him whatsoever.

Bitmain S5s sales at the prices required by Bitmain today are almost zero.

That's not true, and prices were dropped again.

For Avalon to sell significant volumes price needs to be equal or better than the SP20s that is u$s 310 (1000 GH x $0.31) including shipping.

The SP20 doesn't exist, its irrelevant.

It set the benchmark price point.

*Lost them lots of money and is now gone. S5's are the current price benchmark, not SP20s.
