In other words: which is the better miner, when- hashing on same speed (1,1-1,3 TH/s)
- powering 2 units by one of these PSUs
- having the same prices per unit to me
- regarding the noise
Appreciate your help. ... - can be undervolted to 10-11V to achieve even better efficiency - in the range of 900/360 (SP20 doesnt really get any better than 900/420). This requires uncommon 12-10V voltage regulators though and generally there's 5%+ losses in doing so What was the lowest voltage someone has verified the chips start at? I had a look at getting a variable PSU in but they were stupidly expensive. |

I've tried being nice to you but everything I post you object to even when you know its right. Like you claiming that my mega link for 12/16 firmware with an identical MD5 is a corrupted version with injected bad things. Literally I can make a post in any antminer thread, and oh look you randomly wander in and 100% refute everything I've said. You clearly have an ulterior agenda here, care to share? I would also insist that you make a scam accusation thread as you're conviction appears so strong. Keep it on topic please ..... and DO NOT try to be nice to me, just state and respond to (the) facts. Ulterior agenda against you ....? Come off it and do not flatter yourself, honestly, why would anyone have an axe to grind with you ..... ? That's the thing though, it doesn't matter WHAT I post - you 100% refute anything I say. And more so than any normal person would... |

Do you guys have an installation videos? complete noob  If you follow the instructions and go slow you should have no problems following it. There isn't really anything that you can do wrong which will cause damage on these. |

Because I put it there to be 100% clear, as I said 5 days ago. I don't really care if you believe overclocking voids the warranty or not - that's your prerogative to do what you want with your warranty. Just don't encourage others to void theirs with false claims that it doesn't unless you want to create a bond. Then those who's units fail under warranty but listened to your 'mod' voided their warranties with incorrect information can be paid. You are such a fool to antagonise bitmain in such a manner. You posting that on the wiki page linked from the main site does not make it a term of purchase. A more appropriate place would be the user-manual ..... and do that knowing pretty well it can not be applied retrospectively, and you should make that clear in the " advice posts" you make on this forum (to the people that are naive enough to take your advice). Just to clarify, how does positioning your S5 vertically void the warranty, or are you just being off-topic for the sake of it? And by the way, this is NOT a bitmain forum where you as the self appointed bitmain representative can dictate what is posted or not, be it about bitmain products or not. You've advised people to upgrade their S3 firmware to your corrupted, self hosted firmware and the same persons have reported failed chips on their rigs from installing your firmware download, how many of those have you recompensed? I've tried being nice to you but everything I post you object to even when you know its right. Like you claiming that my mega link for 12/16 firmware with an identical MD5 is a corrupted version with injected bad things. Literally I can make a post in any antminer thread, and oh look you randomly wander in and 100% refute everything I've said. You clearly have an ulterior agenda here, care to share?

I have an S5 that I received last week that has a dead blade. What's the best way to RMA it? I'm located in the US.
I assume you've gone through all the debugging you can do, including: Did you try to switch to a different port on the control board? I read somewhere that switching to a different port on the control board fix a dead board.
If you bought it from Bitmain they will warranty it. If you bought it from a reseller you have to go back to the reseller.
Yeah, got it straight from Bitmain China. I sent their support an email, hope to hear back soon.
You can usually get a quicker response for US RMAs if you PM BitmainWarranty to arrange an RMA. Be sure to link to your post describing the issues, what type and how many miners you wish to have repaired/replaced and your bitmaintech.com order number. Via the ticket system it has to worm its way one more step to an agent who is in the US. The BitmainWarranty team is mostly US so they're quicker. Thanks, I tried the other port on the controller but that didn't help. Sometimes the Blade comes up after a reboot but only shows half O's and the hash rate is still about half the normal rate. I PM'd BitmainWarranty to see if they can help out too. What power supply is it running on? |

Just found this post here: The heat sink on SP20 is just entry level plain aluminum heat sink, they don't have huge surface area like those heat pipe heat sink with many thin aluminum fins, so the airflow must be very high to reduce the surface temperature
I just measured 20% fan speed noise at 1 meter away with my sound meter app, it is still 67db, and I personal feel is close to in car noise on highway (70+-db)
Would be interesting what hashspeed is reachable with these settings. If the heatsinks are the same as the SP30/35, they've got a 4-5mm copper base do they not? Its inset from the footprint of the main alu heatsink so isn't visible from above. I wasn't able to remove my SP20 heatsinks as they're aggressively glued to the PCBs and would have likely caused damage. |

Dogie is wrong that it is not cooler at least in my case. It is cooler this way with 1 unit in a 12 by 12 by 7.5 very well insulated room.
That's not what I was saying. Given a homogeneous environment its not going to make any difference. If you take it to an extreme of a single 600W unit in a unit with a window open, of course the floor is going to be cooler. My only issue is Dogie; he was helpful with the wiring diagram for using two PSUs with 3 miners; but more often then not he seems misinformed on a lot of different topics. I am not even 100% convinced he actually works for Bitmain or just self appointed himself. But that's a whole other issue.
So because I suggested you should add a "this will void your warranty" disclaimer, you take it personally? Either way I'd rather you not like me then customers' ability to use their warranty be damaged, should they need it. Bitmain has still made ZERO comment on the warranty - or lack there of. So I take your claim with a grain of salt - as it was written by you and only appears burried in some obscure forum on some wiki - where ever that is. sadly this poped up on bitmains site not sure when .. https://support.bitmain.com/wikis/86. I don't renumber seeing that a week ago i all ways look to see what may void any warranty. looks like the S5 discretion was reword about oc. it's gone on there site . Because I put it there to be 100% clear, as I said 5 days ago. I don't really care if you believe overclocking voids the warranty or not - that's your prerogative to do what you want with your warranty. Just don't encourage others to void theirs with false claims that it doesn't unless you want to create a bond.

From personal experience you will not be able to run (2) S5 units in overclock on a single 1300 G2. I own both 1300s and the 1200xi as well.
Many other users are running 2x S5s off a 1300 G2. Its not even 80% load? I'm running 2 - S5 at 362.5 off a single EVGA 1300 both averaging about 1.195 TH/s over the last 5 days. Potential caveat: the 1300 is attached to 240v and the S5's are sitting at about 4 Celsius ambient.

Just get it locally, its a Pi, or WRT, or computer...

I'm not sure you quite realise how much money you're going to end up burning to matyr yourself in the UK, to get nothing out of it. You would have to have absolutely proof of fraud to have him permanently stricken from UK directorships.
Yet another pointless & derogatory spam post from the poop-dawg.....  Anyone who decides to take it upon themselves to bring these crooks down should be applauded by the whole Bitcoin community, not criticised with arrogant "you don't understand" comments. Go back to spamming your own employers threads. @ Biycz: Best of luck to you & well done. Please keep us all informed of proceedings - the whole Bitcoin community is behind you, apart from the poop-dawg of course, cos he knows better...... Note the date on the post Mr troll.... and good job entirely ignoring the content. I was explaining that the UK legal system is extortionately expensive to do anything in. |

Are the mounting holes for Core i7 cpu heatsinks?
Was thinking of using maybe CM Hyper TX3 evos
As long as its compatible with socket 1150, 1155, or 1156 then sure. So yes. |

So i have been really confused over the whole UserID.worker thing please explain to me what the worker part of it is and how do i know what it is can i just pick a random thing so (user.ctsdfcvjygaviyg)?
I hope that wasn't to hard too understand
Thanks,
Zetoid
UserID = your username on the pool, its what you login to the pool website with worker = the name YOU give to any miner. It can be whatever you want. Ie zetoid.AntminerS5_a, zetoid.AntminerS5_b etc |

Apparently from Dogie's reply in the AsicTube thread I can't mix and match (daisy chain) on the Prisma and AsicTube as they will only hash together at one rate.
So let's leave the AsicTube alone with nothing daisy chained on it.
That's the best idea. Can I run Prisma1 on just the Raspberry Pi.... with.. the USB dongle attachment (for white cable).. and LAN cable (from Pi to switch)... and.. I'm guessing Minera installed on the SD card located inside the Pi?? No Block Erupter on the Prisma. Is that possible?
Yes If Yes; please guide me. (I bought this setup on eBay). The guy who sold it to me tells me it's already all configured. I just need to change my IP.
Well.. (I'm not too IP Savvy but I'll try to explain)
Everything here is setup on IP 192.168.1.XXX
The stuff he gave me operates on some 10.255.255.XXX (something like that)
My router has it's own IP.............I think...
Like when I do IPCONFIG.... well.. it's completely different than the IP he wants me to modify mine too...
So I tried configuring my IP to operate on the same as the Minera... no luck with that.
I was getting an error when generating my IP in network settings.. something about the default gateway not being aligned with my IP (or subnet?)
If anyone knows how I can change my IP to communicate with the Raspberry PI's current settings (the 255 type IP)..
I'm pretty sure it's not possible to change my router (which is not a 255 type..)
So what it sounds like that the Pi is configured for you, but its sitting at an IP you can't get to. One solution is changing your router's subnet to get there, but it sounds like you've tried already. The alternative is temporarily changing the IP of just your computer so the Pi and computer can talk to each other. You can find instructions for this in several of my other guides, referred to as "Alternative Subnet Change". Once you're able to talk to the Pi, try and set its network settings to DHCP. That will mean when you plug everything back to how it was, the Pi will accept whatever IP its given by your router. You can find out what this is on the list of devices on your router's status pages. |

Hello I have a problem with an PRISMA it will not start hashing by any means.
I have 2 prismas one of them is HASING with no problems, they are connected to a controller.
I tried connecting only 1 by 1, the other will not start hashing.
The controller sees all boards, all chips are fine it just won't start hashing.
any solutions ?
Is that image with one or two Prisma's plugged into that one controller? You may have conflicting board identifying switches, which have to be unique across all 8 boards. There is a 5 bit switch on each hashing board which must be configured to be unique in order for the controller to detect it. Do not touch switch 5, but make sure the combination of switches 1-4 are unique across all 4 boards. |

Apologies for the delay, I will answer as reference for others however. That PSU is difficult to arrange as it has split and uneven 12V rails (40A and 85A). One would assume that the 6x PCI-E are on the 85A and the other cables (ATX 8 pin, 24 pin, molexs) are on the 40A. If so, I'd recommend you do the following: Board 1: PCI-E + PCI-E Board 2: PCI-E + PCI-E Board 3: PCI-E + 2xmolex to PCI-E Board 4: PCI-E + 2xmolex to PCI-E |
