i put 3 coolermaster v1000
at neptune

but after a while the hashing speed is down
and each asic card from 298watt got to 218watt

any solutions for that?

hashing speed at 2500 gh max

What temperature your VRMs?
Look on ADVANCED page.
Do not leave web browser on ADVANCED page for long time.
It causes slowdown of miner.

You may have die turn off because VRM is too HOT.

YMMV

is better to put off the cover of the cubes??

No

If you run them open you need to make other arrangements for lots of airflow.
The cube acts as an air tunnel.

YMMV

[jelin1984]

ok also please tell me the fan to replace it with something better

[jelin1984]

does anyone push the mh at 500 mh or not?
hashing speed?

Yes, Elenelen posted this one page back : https://bitcointalk.org/index.php?topic=170332.msg7564241#msg7564241

Alright, I have finished a process for making a heavy duty 2:1 PCIe adapter for Neptune owners.  It is made with 16AWG wires and minifit HCS (high current system) pins capable of 13A.  It is tricky to make with crimping two 16 gauge wires together but I soldered the pins to the wires after crimping for best contact.  I cannot guarantee that the nylon housings at the pcb won't melt so be sure there is some airflow there.

Here she is:


Pricing is $8 each with discounts for larger orders.  Shipping will be priority mail with tracking which is $6 for US and $24 for international.
Please PM if you are interested.  Thanks

Another solution (but a lot more DIY work):

How did you connect the pads between the pcbs?

Another solution (but a lot more DIY work):

if anyone is interested, I have plates that replace the mounting apparatus they used.  It will get the foam out of the way of the VRMs and allow more airflow over the PCB.

They'll come with the plates, screws, nuts and spacers for all 5 ASICs - .0675 BTC plus shipping (USPS Priority/Priority Express, your choice)
PM me ...

Sorry but they will not fit !.... you need an T-shape plate, and not an I-shape

So basically, the neptune is another DIY kit?  Im glad I took the frankencrap, I guess???

How do you get these "Neptune" things to go up past one terrahash consistently?

After putting overkill amounts of power supplies, now up to a total of four power supplies to power the five cubes plus controller, all five cubes now look about the same, that is, no indication that any particular cube has problems, although the interface does not show how many hashes each cube is getting. They all have about the same voltages, currents, and watts. The grand total hashing shown by the little LCD screen ranges from 750 gigahashes up to sometimes as much as 1.2 terrahashes.

Frequencies and voltages are at factory defaults. I have tried RC6, RC8 and RC9 firmwares.

This is basically as good as it gets using factory settings, so what the heck are people doing to get two or three terrahashes out of these things?

The power supplies thing was because even using 1200 watt supplies many were not able to run two cubes well. I had a couple of coolmax ZPG-1200B for example one of which seems to have given up the ghost completely after trying to power three cubes the other pretended to power two cubes but one of the two always sat at 3 to 9 watts total power usage. So I now have that one powering just one cube and a coolermaster EX2 725 powering the other cube. I had another EX2 725 powering another cube but had not really wanted to use this second one to power the cube that the ZPG-1200B wasn't seeming to work well for because previously when I had been using both EX2 725's to power one cube each one of them had turned itself off, presumably indicating that either that PSU or whichever cube it had been powering when it turned itself off was somehow peaking or something enough to have 725 watts borderline even for just a single cube...

wonder if all yer cubes are running on half power...cause 1.2th/s is alittle under half the 3th/s...show us yer advanced page...maybe your psu's can handle it? or knc crappy units

I don't know how to post images, I am familiar with pastebin sites but not sure how people paste pictures.

The page shows wattages usually 265 to 297 or so, but flicks to tiny numbers like 3 or 9 watts from time to time for moments too.

Temperatures of dies in one ASIC range from 77 through 93 degrees. Possibly it is throttling a lot due to temperatures or something like that.

Actually just saw one have a range of 74 through 95.

It doesn't seem to be throttling the 95 either so maybe throttling due to temperature is not what is going on.

That last ASIC happened to get snapshotted just when it showed low wattage; the numbers fluctate, so shortly it again looked much like all the others.
