couldn't resist...



Looks like I'm going to be fiddling with setting up a couple Neppies on Maui, and we have the ax1200's already, lol. Oh well.

the ax1200I should be able to run the neptune without any special bootup procedures right?

Based on what Neptune users have reported thus far, you WILL need special bootup procedures for this PSU. See KnC's troubleshooting guide under the heading "PSU powers off when ASIC boards are connected".

If you haven't bought your PSU yet, get EVGA 1300W Supernova G2, good reports so far. Or Seasonic X-1250.

I understand what you mean

So what about 2 ax1200is for 4 neptune cubes and then run the controller and 5th cube off of another 800 or so watt PSU -- that would work without any special bootup procedures right?(i'm asking this because my friend has spare ax1200s)

Im not an expert but maybe it has to do with initial power draw from the asic boards to the psu.   And every psu is not the same how they handle this initial load, which is different than a continuous load draw after everything is running.  It takes more load/torque/power etc  to start something than to keep it going.

Be careful with choosing psu,otherwise you will break your miner.Always try to get the recommended watt.

Or, 3 x Cooler Master V850.

You can't tell from the outside.  It's the inside.  You have to know the specifications of that particular psu. Most higher end and high end psu will be single 12v rail.

So can i get some examples of 750 and 850 watt PSU's that are single rail?

Thanks,


will 750W PSU work?

Minimum requirement from KNC was 3 x 750W PSU's.

The price difference though from 750 to 800~850 is pretty insane. $75 to $150. Smiley

mate. i know you well enough to know that you are not gonna burn in your bed. good luck with it.

It is a lot of PCI-e sockets to buy but (unlike KfC) I'm not going to skimp on a couple of $ to hook up a ten thousand dollar miner to power; that would be really stupid.

At this point ROI is so far away that $3 is not going to make a dent in it.

anyone using Corsair RM850? Does it have overheating or auto-cutoff problem?

Amazing what risks people are willing to take. How does this thing even get past customs? Who is responsible if a house burns down and someone dies? This should be reported to the gov.

You are taking responsibility by connecting a PSU to it; that is why KfC don't ship with PSU.

My question is, wouldn't it be better to make up some cables that go from two sockets on the PSU to one PCI-e rather than void my year of Neptune warranty? That and demand compensation from KnC for the woeful inadequacy in their design, obviously.

u27

I doubt such a thing exists but I think the best solution to avoid warranty issues would be some sort of dual adaptor.

Something like this audio adaptor but with PCI-E plugs obviously Smiley



It does now.

AX1200i is single rail and the OCP can be adjusted through GUI..

From Corsair website:

Corsair Link™ Integration for monitoring and adjustment of performance, noise, and OCP settings

Dedicated single +12V rail with user-configurable virtual "single rail" and "multi-rail" software modes

Is anyone having problems with Neptune's shutting down due to thermal issues or is this yet more FUD being spread by haters and envious ne'er do wells towards KNC ?

Anyone who? Only 1 Neptune is in the wild!

I figured you'd be lurking somewhere nearby RoadStress … you are never late to a KNC FUD party and your merry band 'o gentlemen can not be far behind. Now that we have OKAVNGR and RS in play, where is the raskul when you need him ?

If we want to start discussing bitcoin miners that you could cook breakfast on, lets start with that howler the SP10.

Thanks for the heads up on some of the trolls to watch out for. As a new member and soon-to-be Neptune owner, I have found this to be a "Wild West" forum for someone like myself. Just here looking for some straight info that might be of benefit to me, and to make a few sincere posts of my own Cheesy


By Wild West you mean differing opinions? Yes, we have those here. You can choose which to believe. This forum is a good forum and you have a lot of technical people here with various backgrounds that can help you if you have a question. Welcome to the forum from the Ho Ho Troll.

Thanks for the welcome, Ho Ho! I agree that there are a lot of technical people that offer great help here.

Differing opinions are fine, but I'm glad I did my research before reading this thread, because there is also a lot of unmoderated misinformation in this forum (some of it downright malicious). Mining is treacherous enough without individual posters trying to trip you up too!

Neptune trouble shooting guide out now:
http://forum.kncminer.com/forum/main-category/hardware/48166-neptune-troubleshooting-guide

Ridiculous procedure to make up for knc's lack of testing.

And hilariously, the 6 steps lead you to hash at full speed to incorrect pool  Cheesy

1. Disconnect all ASIC boards
2. Power on the miner with only the controller board. Once in the GUI, change your pool details to something that is incorrect ( Yes, that is right, since we do not want the ASIC boards to hash at this moment but we still need access to control the ASIC boards)
3.Power down the miner, then re-connect your ASIC boards.
4. Access the GUI and navigate to the advanced tab, once you are here you should change the clock frequency from 450MHz to 50MHz.
5. Finally, gradually increase the clock frequency in increments every few minutes until you reach 450MHz.
6. Your PSU will then work correctly while your miner hashes at full sp

FUD Alert. The 6 steps are only required if you choose certain PSUs eg. Corsair 1200. The steps are not normally necessary with single rail PSUs, eg. good choice is EVGA 1300W G2 Supernova.

Asshole Alert. What is FUD about posting KNC's own troubleshooting guidelines? And pointing out they are incorrect (which they are)?
