2  Alternate cryptocurrencies / Mining (Altcoins) / Repurpose old MB for ETH Mining (EX58 UD5) on: May 17, 2017, 08:52:40 PM
I have a few of these GA-EX5 UD5 MB's laying around with ram, cpu and power supplies.  I was looking at the diagram and it *seems* like in theory I could run 5 graphic cards off of it for mining.

Anyone used this board or have any suggestions for it?

4  Bitcoin / Mining software (miners) / HF - Tool to set voltages on: June 05, 2014, 05:11:37 AM
Hey everyone we are able to release a tool that allows you to adjust your voltage settings for your Evo and Habanero boards.  

HF has provided us with a python 3 script that we are allowed to distribute.

Basically in a nutshell this is good to use ONLY if your trying to push your boards past 900Mhz because you will need to increase the voltage on the board in order to give the chip more power.

USE AT YOUR OWN RISK, please read the LICENSE FILE first before using this tool.

This only works with one miner plugged in at a time!

The hftool.py utility is used to query and manipulate hashfast module settings.

Requirements:
 Python 3.x
 pip for Python 3.x
 Pyusb

Installing pip for python 3 on most unix systems (command for ubuntu below)
 sudo apt-get install python3-pip

hftool requires pyusb. To install it:
 pip3 install --pre pyusb

Put these into a file /etc/udev/rules.d/01-hashfast.rules:

You will need root access to create this file and also when done its recommended you reboot in order for these rules to take effect.

Code:
ATTRS{idVendor}=="297c", ATTRS{idProduct}=="0001", SUBSYSTEMS=="usb", ACTION=="add", MODE="0660", GROUP="plugdev”, ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="297c", ATTRS{idProduct}=="8001", SUBSYSTEMS=="usb", ACTION=="add", MODE="0660", GROUP="plugdev", ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="2ff6", SUBSYSTEMS=="usb", ACTION=="add", MODE="0660", GROUP="plugdev", ENV{ID_MM_DEVICE_IGNORE}="1"

RUNNING

Start the tool by with:
Code:
$ ./hftool.py -h

Read die frequencies and voltages:
Code:
$ ./hftool.py -r

Write die frequencies and settings:
Code:
$ ./hftool.py -w 0:VLT@FRQ,1:VLT@FRQ,2:VLT@FRQ,3:VLT@FRQ

example would be setting all dies to .930 volts at 875Mhz
Code:
$ ./hftool.py -w 0:930@875,1:930@875,2:930@875,3:930@875

You can grab it from Bitbucket Git depo here https://bitbucket.org/gateway69/hf-tool

AND no I dont work for HF, we pushed them to get a tool released so our customers of our Habanero boards could tweak and push their boards.

Order your Habanero from Batch 2 today for $850 here
5  Bitcoin / Mining software (miners) / Pepper Mining App on: June 01, 2014, 05:59:34 PM
I just released a early preview version of the Pepper Mining app that works with cgminer and any board using the HF Golden Nonce chip Habanero boards are using.

The idea of this tool really is to help you get proper cooling on your boards since this is one of most important aspects of being able to increase hashing rates.  I have tested several Habaneros over the last week and getting the cooling head aligned isn't an easy task.

Steps:

1.
So what I do is put the cooling head on and tighten it till i start to feel a decent amount of resistance on the screw heads (you will need to play with this to figure out what that is).  Then I launch cgminer at a low hash clock rate such as

Code:
cgminer --hfa-fan 100 --hfa-temp-overheat 110 --hfa-hash-clock 300 --api-listen --api-network

If you applied enough basic pressure this should be running fine, if your getting thermal trips then you do not have enough pressure so find the screw or screws that need a bit more pressure.

2.
If its hashing launch the pepper mining app, and go to the stats graph, this is where you can see how well you did with getting cooling even.



You can see here that asic 1 and 2 are a bit hot or could use some adjustments.  As you can see from left to right they are running a bit higher than the others, and from this screen shot mid way on the right you can see I did a small quarter turn of the screw for asic 2 and the temp dropped down.

This is just an example of how to use the app, once you have properly aligned or gotten them as close together as you can, you can start bumping up the hash clock frequency in cgminer to see what you can run stable.

Pic of the board with the die locations:


One thing is for sure if you want to push your boards stock fans that come with the coolers do not cut it, you need a decent server style fan to push a lot of air though the radiator.  I use San Ace 120 12v server style fans and by using these I can see anywhere from 5-10C drop in temps across the board allowing me to push boards anywhere from 850-900+

7  Bitcoin / Hardware / HashFast Sierra's Owners Thread on: January 26, 2014, 05:11:02 PM
I figured since some people will start to get their Sierras that we could have a separate thread for sharing information about these devices such as how to get started, software updates, firmware updates, general info, tips and over clocking.

9  Bitcoin / Development & Technical Discussion / Calculating Estimated Diff Change on: January 08, 2014, 10:38:41 PM
Hey everyone, I think this been covered before but I couldnt find a solid answer to the question.
I'm querying my bitcoind to get various details out it then I wanted to calculated the estimated change or best possible way to do it.

Here is the current data that I'm collecting, I hope I also got the right first block of the current diff and last block right..

Quote
Estimated formula 1418481395.2626*(600/((1389220457 - 1388624318)/1170))
Estimated New Hash Rate = 1,670,372,077
Estimated Change = 1.1775777125805
Current Block = 279378
Current Difficulty = 1,418,481,395
Current Block Hash = 0000000000000000eea976a669c940e408e269d4984370ad1c3059db09dad86a
Current Block Hash Time = 1389220457 or January 8, 2014, 2:34 pm
First Block at current Difficulty = 278208
Last Block at current Difficulty = 280223
Next Difficulty at Block at = 280224
Number of Blocks till next Difficulty 846
Number of Blocks posted since Difficulty started 1170
Next Difficulity in 5 days 21 hours

so what im using to estimate the next diff is the following..

Quote
current difficulty*(600/((time of latest block - time of first block of this difficulty)/number of blocks since first block of this difficulty))

Does that look right, or can anyone shed some light on what I might be doing wrong or missing.

Cheers!
10  Bitcoin / Hardware / Have 8 BFL chips.. what should I do with them? :) on: December 06, 2013, 10:02:22 PM
Anyone.. Smiley It seems that all the boards out are in the $300 range and well honestly I dont think that would ROI at all and would just be some device sitting on my desk that might make me some extra cash.

I could melt them, hand them out as xmas pres.. any other thoughts?

14  Bitcoin / Development & Technical Discussion / Bitcoind taking up 380megs or more.. ?? on: July 31, 2013, 08:23:28 PM
Hi, im running the release  "version" : 80300, compiled from source from github on a ubuntu 12.04.x server

After all the data was downloaded the memory usage sits at around 380megs .. any reason this is so high w/o anything going on yet.. ?



and htop says..



15  Bitcoin / Development & Technical Discussion / Computing guestimated ROI Change from blocks on: July 30, 2013, 09:36:10 PM
I'm wanting to work on spitting out some data into a table of current block, block hight, and guestimated diff change.. anyone know of a formula or that could be used to calculate this based upon of course best guess.

Right now I have this data at least getting spit out:

Current Block = 249313
Current Difficulty = 31256960.727769
Current Block Hash = 000000000000006c911cddd6813dd4c680c6b8f3915c853992e1ca15eaa36a3d
Current Block Hash Time = 1375219808 or July 30, 2013, 2:30 pm
Last Block at current Difficulty = 249983
Next Difficulty at Block at = 249984
Next Difficulty in 671
Next Difficulity in 4 days 15 hours 50 minutes

any advice?

17  Alternate cryptocurrencies / Altcoin Discussion / [XPM] BFGMiner Prime Branch on: July 13, 2013, 12:47:55 AM
So some of us on #eligius-prime with the help of Luke were able to get what we think is bfgminer prime working, how ever the people testing it so far none of us have found a block so a word of caution.

I thought in the spirit of sharing I would let you guys know how I was able to get up and runnning, NOTE you do need to know how to compile BFGMiner, I cannot help you with any compile issues ..

Requirements:
primecoind running

Then

Get the latest code from git..

git clone -b prime https://github.com/luke-jr/bfgminer.git

make this change >> http://pastebin.com/XSTTRNF9 << src/libblkmaker/base58.c around line 120

This allows you to use your primecoin wallet address instead of having to convert that to a btc wallet address.

Once compiled and primecoind is set up and running.. use this command line in bfgminer..

./bfgminer -a prime -S noauto -S cpu:auto -o localhost:9912 -u primecoinrpc -p {rpcpassword} --coinbase-addr {primecoin wallet addr} --debuglog 2>prime.log

you dont need the debug at the end but gives you an idea of data coming though..

THIS is WIP, I would ask anyone to help optmized, fix, or make adjustments..

cheers..

here is my miner running.. no block found yet tho.. we did test it on testnet and it did fine blocks fyi..

WIP, but deff would like any patches or updates! cheers!
19  Bitcoin / Hardware / Avalon.. Any updates on when you will start to ship ? on: June 29, 2013, 08:22:43 PM
I know everyone is eager to find out, as far as I know no new info has been published about actual dates of some of the first batches, can you guys give us an update on this?  I think a lot of DIY projects are coming along quite well and even some boards that will try to push the chips hash rate a bit higher.

Anyhow anyone care to shed some light? I'm sure the orders are in with the fab and im sure they tell you when they will be done?  Huh

20  Bitcoin / Hardware / Looking for bloggers for asic site on: June 23, 2013, 09:51:07 PM
Hi, I thought I would set up a site that provides updated details of the current DIY projects and posts about the updates that are happening.  While this form provides great information we all know having to read though 100's of pages for a post to find info your looking for can take up quite a bit of time.  Not to mention all the side tracking of info, trolls etc.. anyhow I was looking for a few eager people that would help me weed though this info and post the relevant updates about the projects or other asic related info.

I have set up diyasic.com and it has some of the basic info covering 2 projects the burnings and klondike systems.  I know a few others our out but im slowly compiling info and weeding though the forms for the relevant info.

if interested in helping out send me a pm..
