VMC Fast-Hash One Prospector 512GH/s 0.7w/GH - Setup Guide [Self Moderated]

[computerjesus]

between the 2 of us its only 14 prospectors. but i dont have them anymore. i returned them to ken in hopes for an exchange for working ones. I wish i would have tried this sd image on the raspberry pi before i returned them but im thinking its the same image as on the pi ken gave me. these are supposed to be quality checked so when he said that these should plug and play with the pi he sent me i have to assume that they are all non functioning. he was supposed to get back to me on friday but apparently didnt get into the office until late. im expecting to hear from him on sat.

So did he exchange them?
Or are you getting a refund?
From the sounds of it you're getting an exchange?
Just be careful with that guy. I don't trust that fucker.

So did anyone other than bar graphics get one of these that work.....??

I've been watching this closely :

https://bitcointalk.org/index.php?topic=491609.0

Update [April 21 2014]   Computerjesus and Kodemadge are friends and they were talking about the same order I've updated the DOA rate to 60% accordingly.

So, of the 25 known boards ordered:

15 Delivered are dead on arrival (computerjesus/ Kodemadge)
4 didn't get delivered (emjay47)
4 delivered and working. (2 to bargraphics & 2 to 'unknown user')
1 Delivered (of 5) waiting for confirmation of working unit (emjay47)

If you're still having issues with it then go to the hash fast baby jet forum as it's the same card: https://bitcointalk.org/index.php?topic=426644.0

Might as well add onto this have been talking to emjay47 for the past couple of weeks. I ordered 6 prospectors on 2014-04-02 16:38:06 and they have been shipped on their website on the 2014-04-11 21:50:53,
Still no signs of a single boards, Ken has told me that he is finally shipping them but he said FedEx has problems with my address so i resent him the address and i am seeing if he will ship them today, I will give you an update today  ASAP.
Thanks

Thanks for the info - I'll update the unofficial thread. https://bitcointalk.org/index.php?topic=491609.0

If anyone else has any more orders to add to the list then feel free to contribute there.

Dude my remaining 4 prospector boards were received today .
Ken has now completed my order fully .

[computerjesus]

But do they work? You never even said if the single board you got worked.

[emkay47]

Hey , sorry i forgot to post it here earlier .
My 1 board which i received earlier works perfectly and have been on since then .

I just received these 4 boards , will be going to my DC in a few hours to hook them up .
Will update it here .

[emkay47]

I don't know , I installed 3 of the 4 boards , and all the three are showing some '' ZOMBIE '' error on CGMINER .
After trying again and again , 1 of them is getting hash on at 300GH /s for sometime , then again going to ''ZOMBIE'' .

I am using a single scrypt for all my boards , which also includes my 1st delivered board , which has been showing 800GH/s on CGMINER for a week now .

Somehow , eligius is not accesible right now , i guess the webpage is down . So i can't check the stats on eligius .
But this what it is on CgMiner -

HFA 1 - 800GH/s apx. ( @ Eligius 500-600GH/s )
HFA 2 - 300GH/s apx.
HFA 3 - ZOMBIE
HFA 4 - ZOMBIE

I have not yet hooked up the last remaining card . Its late here , will do that tommorow .

Also when it goes to ZOMBIE , it shows some libusb error .
I have no idea what it is .
I am gonna go through threads tonight to look for a solution , if there is any .

Someone a bit help please .
And i am ready to offer 0.2 BTC to anyone who can fix this over Team Viewer or through any other sharing .

I don't know what is going wrong . I just want them to get hashing already .

[computerjesus]

Lol sound doa to me.

Hey just got back from being out of town since last Monday,

I had Zombie errors too with my boards, I think it might be related to the board not getting enough power but cannot confirm because my issue kind of disappeared by itself, now I only get Zombie if one of the PSUs are not on.

To troubleshoot the boards only connect one at a time and see if they load up.

I just under clocked them again at 500 . Both my working boards are giving approx 600GH/s on cgminer .
My other 2 boards still don't seem to work .

I'll reconnect them again tomorrow after rechecking the power wiring again .

On CgMiner , It also said something '' Thermal overload tripped ! '' .
It sometimes accepts a share or two , then again goes to ''Zombie'' .

The temperature never rises on the Zombie Board , it remains at 17C then goes to Zombie .

Never ran into that,

Maybe the water cooler isn't correct set or it could even be too tight which is known to cause issue.

Ya maybe , Ill reconnect everything 2mro .
I hope they work .

These are used hashfast baby jet boards that have known problems. one of which is a broken temperature sensor and a firmware problem.

If you go onto the hashfast baby jet users thread - they may be able to help you but ut would seem you have a dead on arrival card. File a warranty claim ASAP - you only have 10 days to do this.

Also it would not surprise me if bargraphics was the previous owner of this card as he has approached ken in the past to sell him his used mining equipment.

You have some serious issues man but we'll work past those.

My boards are still mining on my account and I've had no issues with them. Anytime you saw them go down it was due to a power outage or I was fiddling with the cards.

I haven't spent too much time with them really pushing for the best settings as I've been away. (Each card is fairly unique in what clock speed it hashes best at)



I don't believe I've ever approached Ken in the past to sell him my used mining equipment. These are also not "used" baby jet boards from Hashfast.

In the unlikely case you do get a grip on reality, please refrain from posting in this thread as it will simply be deleted.

Update [April 30 2014]
The refund check (Now cancelled)Sent in Feb turned up today.
 postmark confirms it was sent in Feb and the check number confirms with what ken said it was on pm. So I can't blame him for this delay. The replacement check should arrive soon.

If ken could have just communicated this postage it would have avoided a whole rigmarole for the past 2 months.

In any case I unreservedly apologise to ken in light of this check arriving when all the evidence was pointing to a scam.

Different cgminer versions are bugged in how they display hashrate for products using the HF global work queue. The stats aren't reliable all the time, so you have to go by your pool speed. What frequency is HFA1 running at?
As long as you don't have too many squelched cores, your raw hashrate in GH/s (before rejects, etc) should be about 768 * speed in GHz.
IE, each chip does 768 hashes per second, so at 650MHz you'll get a max of about 500GH/s

[emkay47]

Guys , so finally after reconnecting everything , 4 of my 5 prospector boards are working perfectly .
I've clocked them at 720 , all 4 of them .
I don't know what frequency they running at , i'll check them soon an will post it here .
Somehow , my remote management is not working and i will be going to my DC soon to fix it .
Ill note down the frequency they are working at .

^ and the 5th one?

I'm guessing your power supplies were too small?
