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

[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 .

I'm guessing your power supplies were too small?

No my PSU's were fine , I am using Corsair RM650 .
I was connecting all of them through cgminer on Windows 7 .
I installed Ubuntu on my desktop and then connected all boards , 4 of the working .
There was some issue on windows i guess .

My 1 card is showing ZOMBIE no matter what i do .
I've tried everything , reconnected everything again , still nothing .
I am going to give it one more try today , if still nothing , Ill ask ken if he can replace it or maybe send me Gold Rush instead .

Toggle the workers to see Prospector boards .

So just to be clear. Of your 5 cards only 4 are working no matter what you do?

Hey there emkay47,

I'm glad you got some more of the boards running.

I recommend doing the following to test the boards:

Turn the Fan Speed down to ~60-70% or simply take it off completely and let it be variable - I've received a PM from HashFast_CL that the boards may not be able to handle the fan at 100% all the time and that it was not even needed. (My Board is still running my fans at 100% and there's nothing wrong with them)


HashFast_CL also said that "Dark Errors" can occur at 725MHz clock speed and he recommends 700MHz.

I've found that each board is very picky with which clockspeed they prefer. I'm running one of mine at 700MHz and the other at 670MHz (I saw a lot of squelching dies on this one).

Once you find the right Clockspeed they pretty much run fairly well.



As for the Zombie I still have a feeling it's not the board but instead of the PSU. Test the PSU with other boards, Test the board with other PSUs.

Also Test using a different USB Connector.

So basically , My PC running Ubuntu is not able to run 5 boards all together .
I installed the 1 board which was not working earlier to another PC with windows , and it seemed to run , but that PC is too old and got shut off after 2 hours .

Yea Bar , you are right , each board seems to have different clock speed at which they work best .
I am trying to figure those out .
I read somewhere today that the best clock is 612 for some reason .
Ill try that again tomorrow .

I don't seem to understand a thing , that earlier also when i was using windows , 3 of my 5 boards showed '' ZOMBIE '' .
But when i switched to Ubuntu , 4 of the 5 boards were working .
Now , again the remaining board seems to work on a separate PC with windows .

Therefore , all of my 5 boards work , but somehow not all together .

Can someone sort this issue , cause its pointless to run 2 PC's , and 1 just for 1 board .
I would prefer to run all 5 on a single PC .

Must be nice. I got 14 doa boards. Ken told me it was hard to believe they were all doa. So he sent me a raspberry pi. He said that the boards would plug and play with the pi. They didn't. So I ask if I can return them or get a refund. He said return them and if they work I'm going to charge you a 20% restocking fee. I said you'll have to prove to me that they are working if u want me to do that. So I drove to Springfield mo to their warehouse. Ken wasn't there but i talked to two other employees. I returned the boards to them. They said ken would check the boards in two days when he got in to mo. A week went by before I finally talked to ken. He said he was sick and hasn't checked them yet but that he would check them that night. He also said if they were all doa he would replace them immediately. Haven't heard back since. It's been a month since I was shipped 14 dead boards. And I don't have a refund or replacement prospectors. Wtf!!!!!!!! Worst customer service ever. @ KEN. Money or miners. But I want them now or I'm going to the mo da and ada

I firmly believe this is a hashfast/mining program issue.

I had this same thing happen with two of my boards. Then all of a sudden they just worked and now they don't stop working.

It's extremely odd, maybe try loading each one up individually on it's own CGMiner instead of all together.

That is hard to believe but yes the customer support is garbage to say the least.

The people working might be doing the best they can but there's simply too much to do? Who knows either way it's not acceptable.

In the mean time I highly recommend getting used to compiling and installing CGMiner or BFGMiner on linux before you get a replacement (If you do not get a refund). It will save you a lot of time (Ask Vince )

[emkay47]

Ya man , all my boards are working now . Ubuntu box rocks !!
All 5 of the are running perfectly , though not on same machine .
I am now using 2 ubuntu machines and have divided the boards to them .

[btchedge]

What version of CGMiner are you guys using? And are you setting any of the following...

--hfa-hash-clock
--hfa-fail-drop
--hfa-fan
--hfa-noshed
--hfa-temp-overheat
--hfa-temp-target

Also, do you happen to know what version of the firmware you are running?

[computerjesus]

Yeah. We tried Ubuntu and Linux mint. Nothing.

[rogerli9]

Hi all, if anyone can help me i will be greatly appreciated
2 out of my 5 prospectors that i ordered are working, but my computer can't detect the other 3, i have used the device manager but it doesn't show the 3 boards, and i have tried using zadig and cgminer to try and detect them but no my computer still doesn't register them. Any help would be great
Thanks
P.S. my other 2 boards are hashing at a combined effort of 980 ghs which is at a 729 mhz, the first one is at 515ghs while the other is at 480ghs, if you guys can help me boost the second card up, that would also be great
THanks

[testh]

Hi, is can 4x Gold rush 750Gh/s connect with 1x RASPBERRY-PI MODEL B 512MB VERSION 2  via 10port USB hub ?  

[computerjesus]

That nice that more people are getting working products. Why didn't I get working products. Why didn't the products I drove to Missouri to exchange get replaced yet. Why did ken think it was a good idea to manufacture these boards. This is bullshit. I want my money or my product now!!!!!!!!!!!

Probably will have better luck driving up there again and getting it :/

[venom2049]

Im trying to buy a couple goldrush cards but their website nor their website is working properly blah

[computerjesus]

I gave Vmc 26000$ ten months ago and I don't have a working product yet. Your better of not buying cards from them.

[emkay47]

Hey Guys ,

I am selling 5 x Prospector boards including H80i Water Cooling and Corsair RM650 .
All 5 of them have been running perfectly between 400-500GH/s .
I am located in India and can ship worldwide .

If ill send the H80i's and RM650's with their boxes , the shipping charges might get high . So , i am willing to send either way , with boxes or without .
I am open to sell just the Prospector boards also , without the cooling and power .

I can escrow too .

Price :-

5 x Prospector Boards + 5 x H80i's + 5 x RM650 = 8.5 BTC
5 x Prospector Boards = 5.5 BTC .

Shipping Charges = PM me with location and option , Ill get back with shipping charges .

Cheers .

I'm taking a punt here... half the USB headers are plugged in backwards...

[computerjesus]

Lol. I tried them backwards too. Just to cover all basis. I told ken I was gonna have him shut down. It took me about a month but Vmc has been ordered to halt operations in large part because of me. Now ken, if you want to get back to business as usual you will refund me all of my money. I will drop my complaint and tell the Secretary of State to drop their investigation. If not, more problems will come your way, I promise.
