1  Alternate cryptocurrencies / Mining (Altcoins) / $770.57 Starter Rig; $1650.53 Example Rig on: May 09, 2019, 12:19:28 PM
$770.57 example 2x starter rig

Can be expanded to 6x GPUs for an additional $879.96 or $219.99 per each 1660 GPU.

To be 100% clear; I am in no way affiliated with any of the following products or the companies which produce them.  

I do not receive any compensation, in any form.  The links to amazon are NOT referral links.

I have recently seen companies trying to sell overpriced nonsense to miners, and would like to offer a better alternative.

Many mining OSes currently have a problem with 1600 series working correctly.

I have tested these components with both versions of oros and they work without issue.  

If you are a US resident and would like to thank me for this list, please try openrig.net/oros.

$10.85

total:
$770.57

Many of these items can be found for less on ebay used; however you do have the advantage of having warranties if you buy new.

You can use my mining electric cost calculator to estimate what the electric cost of this miner would be for you.  I recommend using a 70 watt power limit unless you have less than $0.075 cent power.  Here is the result for $0.10 cent power (the US average) $13.90 a month:




This table shows the 1660 mining performance with popular coins:





You can use this information and whattomine.com (or another profitability site) to estimate mining returns.  

Using 70 watts and 17 MH/s on RVN on May 9th I get:

$0.48 per GPU revenue, or $0.96 for a 2x rig.

0.96 x 30 (days in a month) = 28.8 - 13.90 (estimated electric cost for those with $0.10 cent power, substitute your own power cost)

Which results in $14.9 profit a month for a 2x rig at current rates.

While this is not a lot of profit for a $770.57 (its just under 2% a month or 23% a year) investment, it is extremely low risk vs buying altcoins directly.

This is also a starter rig with only 2x GPUs.


If you spend $879.96 more for a full 6x rig; totaling $1650.53:



$0.48 per GPU revenue, or $2.88 for a 6x rig.

2.88 x 30 (days in a month) = 86.4 - 34.06 (estimated electric cost for those with $0.10 cent power, substitute your own power cost)

Which results in $52.34 profit a month for a 6x rig at current rates.

While this is not a lot of profit for a $1650.53 (its just over 3% a month or 38% a year) investment, it should outperform almost all standard investments.

Note:  Mining returns are extremely volatile, this is a PROJECTION of potential profit using the mining difficulties and probabilities as they are on May 9th 2019.

It is possible that mining returns could reduce significantly.  In this event a miner can always sell the parts to recoup a large portion of the investment.  


1660s will retain their resale value well.

Fellow miners,

I made this tool last year for openrig.net and ultimately decided not to integrate it.

It allows you to easily estimate your mining electric cost using details from your electric bill and rigs.

It is built with HTML and jquery 3.4.0.

If you download the Github repo

and run it locally in your browser;

you can edit the default configuration json(s) (lines 29-39 near the top of the file)





to allow your configuration to persist.

3  Alternate cryptocurrencies / Mining (Altcoins) / 1600 series Nvidia GPUs are significantly better than everything else. on: March 16, 2019, 12:59:20 PM
1600 series Nvidia GPUs are significantly better than everything else for mining. 

The 1660ti almost matches a 1070's performance with only 75 watts. 

Currently, most mining clients donít support the 1660 or 1660ti.

Linux drivers currently only have limited support for the 1660 and 1660ti.

The 1670 or 1670ti will be the next GPU that will be optimal to buy for mining. They will likely have a 150-160 watt TDP, with an optimal mining powerlimit around 90-95 watts.

plan accordingly Grin

Fellow miners,

this is the build I use with my Nvidia rigs.  

Openrig.net/oros makes it easy to configure, edit, and monitor rigs from your pc, tablet, or smartphone.

https://openrig.net

Why you should try openrig.net/oros:

     Email/telegram alerts for all rig events.

     Both openrig.net and oros are extremely secure.

     Oros has effectively zero writes with all scripts, configurations, and clients pulled as needed from openrig.net and stored in ram on oros.

     Oros will self heal from almost any problem.

     Currently has a 0.05% fee; which may be reduced.

Requires:

     Nvidia GPUs

     16 gb or larger USB key

     You are a resident of the United States.

Example rig:

$770.57 Starter Rig; $1650.53 Example Rig

5  Alternate cryptocurrencies / Mining (Altcoins) / [OS] ocFACTORY easy-to-use Linux Imaging Solution v0011 on: July 01, 2017, 06:11:10 PM
Fellow miners,

this is the build I use to image nvOC and rxOC USB keys.  I am providing it to the community 100% free, with no fees.

ocFACTORY is a customized Ubuntu 16.04 build which is ultra portable and should work with any computer (tell me if it doesn't work with yours).

ocFACTORY is easy-to-use and includes the nvOC_v0017 and rxOC_v0012 images.

Current Version: v0011

 
Change Log:

v0011 (initial release)


If you don't have an imaging program already download HDDRawCopy (Link)

Or get etcher for Mac / Linux / Windows Link

v0011 zip should extract on OSX / *nix / Windows  Wink

v0011 is 62.9gb

Please Note: ensure your build PC has at least 90gb of free space before downloading. This is the total space the zip + extracted img will take up.



ocFACTORY_v0011 Google Drive Link use this image for all PCs



ocFACTORY_v0011 MEGA Link use this image for all PCs


The SHA256 hash (for the zip) is:
Quote
967ad90fe4d3dc30f9545cfa86e1b3ea3857832e49a84524a42d39712d858505

To verify the downloaded zip see this post Link



ENSURE THAT YOU unzip the image BEFORE YOU IMAGE YOUR USB  Wink


Use HDDRawCopy or etcher to image the extracted img file to the 64gb or larger SSD or USB ( see this guide for an HDDRawCopy walkthru )


I recommend imaging to a sata or m2 SSD; as it will most likely be able to create images 40% faster than if you use a USB key.


At boot etcher will launch automatically.

ocFACTORY includes plusCPU miner and the openSSH client.  It can be used as a control PC for all your rigs.  At boot a bash script called cmd will launch in the guake terminal.  (cmd is located in the /home directory.)

I will periodically update cmd with more features.  Wink

If you are using ocFACTORY as a control PC for your rigs I recommend using the gnome terminal for each SSH session (this is why I swapped the terminal uses).

When I finish the: monitor / push / update / dashboard app it will be optimized for ocFACTORY.

ocFACTORY uses the base Ubuntu driver.  You can increase the resolution by: selecting the ubuntu launcher at the top left and typing:

Code:
ad

select additional drivers

select the proprietary drivers for your pc.

apply the changes

reboot

the root password for ocFACTORY is:

6  Alternate cryptocurrencies / Mining (Altcoins) / [OS] rxOC easy-to-use Linux AMD Mining v_stopgap on: June 25, 2017, 02:56:20 AM
Fellow miners,

this is the build I use with my AMD rx series rigs.  I am providing it to the community 100% free, with no fees (from me at least):  (Claymore's miner still has his fee)

rxOC is a customized Ubuntu 16.04 build with AMD OC support, manual fan support, auto launching on boot, and a single easy to configure Bash Script (oneBash) which can be configured from a windows pc using wordpad.

rxOC is easy-to-use and supports mining (with the v_stopgap oneBash):

 ETH   ZEC   NICE   HUSH   ZEN   ZCL   MUSIC   ETC   EXP   DCR   PASC
DUAL_ETC_DCR  DUAL_ETC_PASC  DUAL_ETC_LBC  DUAL_ETC_SC  
DUAL_EXP_DCR  DUAL_EXP_PASC  DUAL_EXP_LBC  DUAL_EXP_SC  
DUAL_ETH_DCR  DUAL_ETH_PASC  DUAL_ETH_LBC  DUAL_ETH_SC  
DUAL_MUSIC_DCR    DUAL_MUSIC_PASC    DUAL_MUSIC_LBC  DUAL_MUSIC_SC    

xleejohnx SRR implementation Link I will integrate this into the next oneBash / v0013; for now, if you want to use this follow the instructions on xleejohnx's post.

rxOC uses Optiminer, Genoil, Claymore Ethash, Claymore Equihash, sgminer, and plusCPU uses cpuminer-opt;
if you want an additional algorithm or mining client post here or pm me the details and I will add it to the next version

For Nvidia rigs see: [OS] nvOC easy-to-use Linux Nvidia Mining: Link

Current Version: v_stopgap

To setup remote re-configuration of rigs / remote viewing using SSH and screen LINK

How to Setup _Parallax_Mode (have oneBash autoupdate from a pastebin file when the mining process is launched) Guide Link
 
  this version is intended for USB keys and SSD's

  However you can use an SSD or HDD with a USB adapter cable Link

  Or you can follow this process to enable Autolaunch with an SSD or HDD install Link

  
Change Log:

v_stopgap
  removed swap space (improved boot time)
  updated driver to the AMD Blockchain Beta driver ( much better for Ethash )
  ETH, ETC, and ZEC coin selections miner are launched in a screen ( access the screen via the cmd:    screen -r miner   in the guake terminal )
  Updates are disabled.
  added Claymore 10.1

v0012
  added Genoil for NICE / ETH / ETC
  added GENOILorCLAYMORE selector
  added Optiminer for Equihash algorithms
  added OPTIMINERorCLAYMORE selector
  added atiflash (use at your own risk)
  implemented  wget / pastebin oneBash auto-updating suggested by: _Parallax_
  Thanks _Parallax_   Smiley
  workernames are auto-generated (set to the rig host address: last 3 digits of the rig IP)
  added IP output to the top of mining process (easier to get the rig IP)
  added lspci and supported clocks output to the top of the mining process
  added USE_ENVIRONMENTAL_VARIBLES selector (adds them if YES)
  increased primary partition size (more available space)
  added SLOW_USB_KEY_MODE (for slow usb keys; also helps ensure the setting of powerlimits and fanspeeds)
    HUSH COIN selection

v0011 (initial release)


If you don't have an imaging program already download HDDRawCopy (Link)

Or get etcher for Mac / Linux / Windows Link

v_stopgap is 15.6gb



rxOC_v_stopgap Google Drive Link use this image for all mobos

Expected Bios settings (I have not tested all of these for AMD rigs):

If you are using an ASRock H81 PRO BTC or BIOSTAR TB85; either should work with without any changes to the bios settings.


If you are using an MSI Z270-A PRO; ensure you enable Above 4G memory option in the bios before connecting the nvOC USB.  


If you are using a GIGABYTE GA-B250M-Gaming 3; ensure the Audio Controller is disabled in the bios.


If you are using a BIOSTAR TB250-BTC; ensure Miner Mode is enabled in the bios.  Also ensure Max TOLUD is set to 3.5 GB in the bios.


If you are using an ASUS Z270-F GAMING; ensure 'Above 4G Decoding' is enabled in the bios.  Also ensure PTP aware OS: is set to 'Not PTP Aware' in the bios.  Finally, ensure you 'Clear Secure Boot Keys' in the bios.


If you are using an MSI Z170-A GAMING M5; ensure 'Above 4G Decoding' is enabled in the bios.  Also download, unzip and copy to a usb key ( the 2016-12-19 Version 1.D ) Bios and follow instructions to flash the bios.


If you are using an ASUS PRIME Z270-A; ensure 'Above 4G Decoding' is enabled in the bios.  Also ensure PTP aware OS: is set to 'Not PTP Aware' in the bios.  Finally, ensure you 'Clear Secure Boot Keys' in the bios.


If you are using a GIGABYTE GA-Z270P-D3; ensure the Audio Controller is disabled in the bios.


If you are using a ASUS PRIME H270-PLUS; You must update the bios; with this motherboard it can be done by connecting an ethernet cable and entering the EZ Flash 3 Utility.  Select DHCP and download then install the update.  It should look like this.  After updating ensure 'Above 4G Decoding' is enabled in the bios.


If you are using a BIOSTAR RACING Z170GT7; Ensure you are only using the first 6 pcie slots closest to the CPU.  Ensure you set Security Device Support to: Disable Finally ensure you set the max TOLUD to 3.5 gb


ENSURE THAT YOU unzip the image BEFORE YOU IMAGE YOUR USB  Wink


Use HDDRawCopy or etcher to image the extracted img file to the 16gb or larger usb ( see this guide for an HDDRawCopy walkthru )

Image to a 16gb or larger USB key.

NOTE: You only need to configure the oneBash file in the Windows Partition.  If you don't have a text editor with syntax highlighting: open it with wordpad.  I recommend downloading atom if you don't have a text editor with syntax highlighting .

When you are done configuring oneBash ensure that you save, then eject the USB.

Attach the USB key to your rig and power it on.

NOTE: first boot will take longer to start mining as oneBash must be converted

All files are in the rxOC folder Link.

rxOC uses the blockchain Beta Driver.

the root password for rxOC is:

    miner1

Known Limitations and Issues:

Please let me know if there are any issues with this version not OCing cards with mobos.

If your miner crashes at all, it is probably because your OC is too high.  

IMO it is easier to start with a lower OC and walk up the OC until it becomes unstable, than to start at the max and walk it down to stability.

My thoughts on OC Link

If you find rxOC helpful and would like me to expand it; please let me know.  I will make requested changes over time as I am available to.

Requested Changes / Additions / Tests:

a global switch to turn off all overclocking / excluding manual fans  OVERCLOCK="OFF"

integrate SRR support

add UBIQ coin selection

add https://github.com/sling00/amdmeminfo]https://github.com/sling00/amdmeminfo]https://github.com/sling00/amdmeminfo

check into atiflash in it current folder / potentially move to: /usr/local/bin

make rxOC github repo

implement individual card settings

Fellow miners,

I no longer maintain nvOC. 

A community edition is maintained by other forum members.

The community edition is a community fork from the v0019-1.4 version (see post 3)

The community edition has significant changes and many improvements over the v0019-1.4 version.

Please note: I have not tested or verified the community edition.

As you can see in the picture; I no longer have 3 of the placeholders for the 6x 2.5 sata mounts (I only used this item with 3x ssd's which is why I still have 3x of the placeholders)  I do have all the screws for the 6x 2.5 sata Icy Dock.

The Anker Charger comes with the micro usb cables seen in the photos.

The short non powered riser (don't use this with an rx400 series; you might kill your mobo if you do) will work with a 1000 series Nvidia other than a 1050.  Note; it is very short.

The hdmi to vga adapters are self explanatory.

This is a sidehack modded unit; see the groupbuy thread.

Currently running at ~2.35TH/s using 534 watts 120v with freq 525 and manual fan at 25%.  

Has some errors at this setting; however it can be set at freq 450 for ~2TH and have almost no errors.

These units are difficult to initialize or run in the cold.  You may need to hard restart it several times to get it running if your ambient temperature is low.  I recommend changing the fan speed until the chips stay between 60C and 70C, as this seems to be the best operating temperature.

Fan is at 25%, and can probably be set lower depending on the ambient temperature.  

I replaced the rear fan grill with a black one, and added a second to the front.

I will include power and ethernet cables; both short.

Will ship in original box.

Miner has the original firmware, which requires the use of the manual fan setting.

The miner is a batch 3 unit rated for 4.86 by Bitmain @ freq 600.  I run it at freq 625 and it averages 4.9 on slush using ~1230 watts.

I run this miner on an EVGA 1600 T2 with 120v; I have never tested it with 208v, 220v or 240v so I am not sure if it would perform the same with those voltages or with another PSU.  

With these early batches ( at least with 120v power) they have less errors ( and thus a higher hashrate ) when you run them slightly hotter with a lower fan percent.  In my experience these run best at ~62C.
With a 70 degree F ambient I run at 30% fan.  (40% with a higher ambient)

When the miner first starts it will have a high error %; this will go down over time.  Soft restarting (by clicking the Save&Apply button in Miner Configuration) will remove those start up errors from miner status; but this is purely cosmetic.  The error rate will go down over time regardless.

You MUST only use 1x PSU per hashblade.  Bitmain has made it clear that damage is likely if you fail to do so.  
You MUST use 3x pcie per hashboard ( not worth the risk, just order some splitters off amazon if you don't have enough pcie)
You MUST power on all hashboards before the controller (if only using one PSU you avoid this problem)

miner requires 10x pcie connectors

If you need a PSU I can also sell an EVGA 1600 T2 PSU for 0.82BTC shipped

Each Miner will be insured and signature will be required.

I added front fan grills on each miner

Both have the original firmware, which requires the use of the manual fan setting.

The batch 1 is rated for 4.86 by Bitmain @ freq 600.  I run it at freq 625 and it averages 4.9 on slush using ~1260 watts.

The batch 2 is rated for 4.66 by Bitmain @ freq 575.  I run it at freq 625 and it averages 4.9 on slush using ~1320 watts.  It does run hotter and uses ~60 more watts than the batch 1.

I run these on EVGA 1300 G2's on 120v; I have never tested them on 208v, 220v or 240v so I am not sure if they would perform the same with those voltages or with another PSU.  

With these early batches ( at least with 120v power) they have less errors ( and thus a higher hashrate ) when you run them slightly hotter with a lower fan percent.  In my experience these run best at ~62C.
With a 70 degree F ambient I run the batch 1 at 30% fan.
With a 62 degree F ambient I run the batch 2 at 30% fan.  (40% with a higher ambient.)

You MUST only use 1 PSU per hashblade.  Bitmain has made it clear that damage is likely if you fail to do so.  
You MUST use 3x pcie per hashboard ( not worth the risk, just order some splitters off amazon if you don't have enough pcie)

Each miner requires 10x pcie connectors
If you need a PSU I can also sell an EVGA 1300 G2 PSU ( each with 2x splitters + a jumper ) for 0.3BTC each shipped
Note: these only work well for 120v power with the S7's. If you using 208v, 220v or 240v you should get a different PSU.
