Re: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.25/GH & 0.51W/GH
Are the support staff very thick or do they just play the act very well??? Or do they not understand English?
I contacted BitmainTech by email about them changing the price at the time I was purchasing.
My email to them...
I am not happy with your company for changing the price as I made an order. That is the wrong thing to do and misleads the customer. I added the product to the Cart and it was US$341 but when I payed it changed to US$370. If you are going to change prices you should delete the old product listing and create a new one, not edit the product listing that people are currently purchasing from.
I would like a refund of the difference because it was very deceitful on your part. I worked it out to be 0.097 BTC extra that I payed because of your editing.

Hi,
sorry for the confusion.
price will be adjusted from time to time due to marketing policies.
When you place the order, the price in our website should be followed.
Thanks for your understanding.

You changed the price as I processed the order... This is how the events happened.
1 - I opened the product page for the S5, It had the price of US$341
2 - I added the product to my cart, the price displayed was US$341
3 - I went to the checkout to choose shipping and confirm while the whole time it showed US$341
4 - After I had confirmed the order the price magically changed to $370
Why should I have to be understanding? The price changed while I made the order. Like I have said, the price was US$341 until i got to the payment screen. Because of this I did not notice the changed price. This was very deceitful.
Like I said before, you should not be editing existing product listings. If you want to change the price, you should be deleting the listing with the old price and creating a new listing with the updated price.

Hi,
The product in the cart cannot show the latest info after we update it.
Suggest you add it to cart when placing the order, then you'll get the correct info.
We'll consider your suggestion in future.
I can assure you that it DID change. Could someone from BitmainTech actually take this seriously instead of trying to sidestep this.

Re: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.25/GH & 0.51W/GH
I was about to purchase two at $310, communicated with Yoshi to resolve a coupon discrepancy, got distracted with real life, come back and the price was raised.
So why mourn at bitmain? Mourn at real life ...... it's the one that distracted you from the bargain of the century .... Yeah.... no.
How about them changing the price while I'm going through the checkout? Is that alright to do? I think if they are going to change the price, they should delete the old product listing and create a new one. They should not be editing the existing listing because then things happen like the price suddenly changing during checkout without the customers knowledge.

I am not happy with you BitmainTech for raising the price as I am purchasing. When I added the product to my cart it was USD$341 yet when I committed to the order it changed to USD$370. How dare you rip us customers off like that. It is just not the right thing to do if you are wanting to keep your existing customers!!! How dare you change the price as an order is going through.
Edit: It might have only been 0.1BTC at the time but that is not the point. I saved up for that and don't expect a company to trick me into paying a higher price than what was advertised.

Re: ANTMINER S5: 1155GH(+OverClock Potential), 590W, Jan 12th Shipping [Sales Open]
I would suggest that the first thing to do is by hearing protectors. 
Haha, well we have the replacement fans ready to install. And these will be in a server room kept nice and chilly.
We will be selling off some of our B7 / B8 S3+ units to free up some PSUs.
Perfect condition, housed in Server Room at 64 F (approx) Hepa Air Handler. Clean and Like New.
I apologize if this is off topic but if there is any interest just shoot me a PM.
Strato
I am curious though. If these are in a server room, why tinker with the fans at all? Is there a noise concern in the room? I thought the issue with the S5 fan was strictly noise related.
The server room does have a high noise floor to begin with. But I was concerned these might be over the top db wise.
Strato
Also from what I have noticed with servers is that noise affects the performance of reading from and writing to the mechanical hard drives (SSD's are obviously unaffected by noise vibration as they have no moving parts). The noisier the environment, the slower they get.
BTW, is anyone able to compare the noise to an S4 please? I have an S4 and had to find another location for it. I had my neighbour knocking on my door asking what the hell the noise was and saying that he could not sleep with it (we both are in separate houses and his bedroom is about 50 meters away from my house). I have seen reports of the S4 between 70 and 90 db but not sure how accurate they were. It would be great if someone could do a test using the same metering device at the same distances for testing both.
Well now BitmainTech have a new site design and have a FAQ section now. They have put in there (something) about their 90 Day Warranty.
Quoted from BitmainTech FAQ -
"What warranty is provided on the products?
A 90 day warranty is provided after the unit is shipped."
That's it, no more information about it.
And how can BitmainTech justify that warranty starts before the customer is in possession of the product. No matter how legal it might or might not be, I believe that it should be from the day the package is delivered which BitmainTech would have record of from the postal services. The way UPS explained it to me was that the parcel is still the senders until it gets delivered. Until then only the sender has right to the parcel and can change the shipping details, ask for reimbursement for lost items, etc.
Also why should someone need a BitmainTech account to just read the FAQ's? This seems a bit like phishing by making someone who may not actually become a customer to give their details.
Plus there is still the fact that the Warranty Disclosure posted in this thread has no mention of being voided by changing settings that are available without modification.

1. I still can't find it ANYWHERE on your website. I have looked on the product pages, support page (where I thought it would be) and the about us page.
2. I can't see in that Warranty Disclosure where it says if you use the easily accessible menu option and change those frequency settings, the warranty is the void.
I believe that if this is the case, you should be including that in the Warranty Disclosure. And the Warranty Disclosure should be easily accessible via the product sale page and / or the support page.
It would also be courteous to have a warning on the Miner Configuration > Advanced Settings page in the Antminer firmware. Something like "WARNING: Setting the Frequency greater than 200M or Voltage greater than 0725 will void your warranty!"
These are just suggestions to help lessen the confusion of customers. I only know about the warranty because I follow this thread, but a first time user would not expect to look in the forum for it.
Over Clocking will void your warranty on the unit, please be careful 
By the way i dint know over clocking voids warranty as it states -+10% overclocking,underclock in your website on s4. what i did is like 5% increase in frequency i guess.
+- value is the tolerance range for the hashing power in claimed calculation power. With Stock setting it may go up and down up to+- 5%
Actually the exact phrase on the BitmainTech shop product page is "Over clocking: About 10%, but not guaranteed". To me that suggests you can do it but it can't be guaranteed that it will work properly. Also, I have looked through the BitmainTech website and can not find any warranty information on their website or in their manual.
I have now had quite a good run after a lot of headaches at first with crashing and odd behaviour at stock settings. I was scared at first to try any higher settings but eventually got the courage to give it a go. The ambient air temps of the area it lives in fluctuates between 24C and 32C. When the ambient air temp is at 32C the miner does reach 64C, but these screenshots were taken at an ambient air temp of 26C. Also I am just using the stock PSU on 240 Volts.

Re: ANTMINER S4 Black Friday Deals 0.409USD/GH/s, FREE International Shipping
More S1 upgrade kits please!!
you could feasibly use the C1 as a pair of upgrade kits, but its not ideal. Not sure why bitmain isnt selling upgrade kits for ~0.3BTC/kit
How many people would be interested in another S1 upgrade kit batch?
Yes Please!!!
I could be wrong on this: I would believe your network the S4 is connected to would need to be set up for DHCP and you know the address assigned to it [whether it was assigned automatically or manually as in my case] in order to connect to your S4.
Bitmaintech is not responsible for what you do with your network set up and whether you want to connect remotely or not. They are only responsible for the unit. If the unit had problems connecting to it remotely, THEN I could see bitmaintech coming into play.
However, I honestly believe you need to set up your S4 to connect to a DHCP network NOT static in order to connect to it remotely within that network.
I'm not a network specialist. I'm just telling you how I have mine setup with my Airport Extreme Base Station from Apple.

The DHCP server issues the static IP to the S4.
Nothing wrong with 60C, I'm almost permanently at 55-60C due to a 35-40C ambient.
But it is in a shopping centre with air-con and an ambient temp of 24C, so going by your temps it being 46C (coolest board) to 51C (hottest board) seems normal. I don't think the 61C is normal at that ambient temp of 24C. It was only 1 board that was reaching high temps, not all 4. The other 3 boards were still running at around the temp they normally are. I monitor this miner several times a day so I do know what my average is for my miner.It is currently stable with the hottest board at 51C now and hashing at 2TH.
This is a software problem. Sometimes i have it too, after power failure.
You can stop function - Stop running when temprerature is over 80℃ - only thing you need restart miner with PSU manually.

Well the first time it was running hot, it was not responding to via HTTP or SSH. It just crash and continued to run hot. So if it has crashed I'm not sure it would be able to monitor the temp and stop at 80C.
I had a situation with my S4 2 days ago where I was changing pools and after I clicked save & apply it crashed.I could not access the web interface nor was it mining to any of the pools. It took me about 2 hours to get to where it is stored and it was running quite hot and roaring like it was trying to take off on a runway. I did a hard reboot and monitored it for an hour. Everything seemed to be running better than before since it was now hashing around 2.1TH instead of 1.9TH so I went back home. After about 3 hours running I noticed the temp rise on 1 board from 49C to 61C. I was not able to get to the miner to reboot it again so it ran all night like that with me stressing.
As soon as I could get to it I hard rebooted again and monitored it for about 4 hours this time. Every thing seems to be running normal again with the boards at 51C and hashing at 2TH now.
I would love to know what could cause this so I can try not to do it again...
How can I remotely stop the antminer? I know I would only be able to stop it if I can connect to it, but when it is running hot and it seems like something is wrong I would like to be able to stop it so it does not damage itself.

First off, your IP Address provided to you by your IP needs to be a static IP instead of dynamic. Mine was dynamic with charter communications. I had to upgrade to a business line with them to get a static IP. I'm paying $21.00 higher each month for it. The plus side is if my internet goes down, they are supposed to have me up no more than 4 hours later. They give business subscribers higher priority over residence.
Once you have a static IP, I would recommend you going to youtube to see what you need to do to connect to devices (your S4) through your router and/or switch that are connected to your modem. I'm saying to go to youtube because of so many different OS's out there; versions of that OS; routers, etc...
I'm assuming you are set up for DHCP. You would need to know what address was assigned to it or that you manually assigned to it in your settings so you can connect to it after you connect to your router via the static IP address.
The router would have to be set up a certain way, etc... That's why I'm saying go to youtube after you get static (same IP address all the time) instead of dynamic service, which changes the IP address all the time.
For instance, this youtube video tells me what one would need to do in a similar situation you're in with an Apple Airport Extreme Base Station: http://www.youtube.com/watch?v=gpeRdji4BmM
Yes, they talk about connecting to other "Mac's" within your house or business. You can also connect to any other devices assigned addresses in DHCP in Airport Extreme Base Station. However, you first need a "static" IP address to connect to the Base Station so you can connect to other devices through the Base Station.
As for what could be wrong with your S4, I have no clue. Not my expertise. Good Luck!
Wait until others wake up and head to the forum to read new posts. Then you may find your answer.
I'm just hoping someone who has played around with an S4 a lot or staff from BitmainTech would be able to shed some light on this matter because so far this has not been easy to manage remotely with the issues I have been having, for example with 1 board randomly over-heating when compared to the other 3 and hash rate changing after reboots.
After reading the posts about the voltage regulators not functioning like they should I am a little worried this might be a similar problem or the same thing. And with the stock power supply already close to max it's not good if it is.

guys Im trying to manually set the difficuly on my S4 (with lastest firmware) for P2pool. Im not sure but I think the difficulty should be 2048. On my S1 I used to add a +0.01 after my wallet id , but I dont remember what it was, and that number has changed now. Im trying to use a multipool and my speed is thrashing around alot. Using this setting seemed to help on my S1. Any advise? Thanks in advance.

This is what I wanted to speak about earlier but needed sleep first... But just quickly, I have found +1436 to work best for me and I get just over 1900 ghs. Setting it to +1500 would cause it to mine slower (around 1600 to 1700 ghs) and chips would start to fail after an hour.
I am running the latest firmware and the miner is located in a shopping centre (air conditioned to an ambient 24C) with board temps of 50, 50, 46, 46.
I am running my own P2Pool node since there are only a couple in Australia and their latency was bad for me. Even with my miners being in a separate location to my p2pool node my ping between the 2 locations is on average 14.6ms.
Do I need to make any changes to the p2pool node config, install ck's latest cgminer, or edit the antminer conf to get to the advertised "guaranteed" speed of 2TH?
I have 2 S1's that work flawlessly at their advertised speed so I expected the same company to keep the same standards.
BitmainTech don't love me as much as some of you. I only got 1 C1, 1 S3+ and 3 S4 coupons. I am wanting to give the C1 and S4 coupons to someone who can use them. All I ask for is a donation to help me buy my S3+ as I am 0.3 BTC short for the pair. Please PM me if you would like one or all of them and the amount you are willing to donate.
I also want to make a note on here about BitmainTech giving me the run around for a power lead. I asked them about the 16A lead and told them I was on a 240V power system. After a couple of emails with BitmainTech they were still amendment that I needed a 16A lead and told me to find one online, which I couldn't because the C13 connector is only rated for 10A@250V. After a couple of emails with BitmainTech I gave up speaking with them and spoke with my electrician to see if he could get me the lead BitmainTech was talking about. He told me that the BitmainTech customer support staff don't know what they are talking about and that the 10A lead would fine to use. I then asked BitmainTech to confirm this with someone there that knows about power usage. Surprisingly this time they came back with a different response and told me that the info the electrician gave me was correct. I asked them to update their info on their website for other people on 220-240V so it is not confusing but they have not done so.
So the rule is -
120V needs 16A
240V only needs the standard 10A
I also have some hashing issue with my S4 but I will post that another time. It's too late and I need some sleep.
