Steps

EDF

1. /!\ Almost no one actually uses the off-peak hours in the evening and at night
2. > So think about the Green package (off-peak hours every weekends and public holidays, so 0.13€) + Single rate the rest of the time (no high and low, so 0.15€)
3. Activate the hourly monitoring of your electricity consumption
4. https://mon-compte-particulier.enedis.fr/suivi-de-mesures/
5. Choose the best plan for your consumption
6. Depending on your consumption, take the best offer

NiceHash VRAM mining settings

1. /!\ Only for NVidia GPU
2. > The miner most profitable, secure and easy to use (In-build overclocking, Auto-overclocking and No Dev Fee)
3. Install "NiceHash QuickMiner"
4. Connect yourself on you account, and set "Optimize" to "Efficient"
5. You will mining less than the standard (100% GPU), but you will keep safe your GPU because you will use its VRAM (so you will be able to continue to use your PC, but not playing games, and use almost no electricity)

OC your GPU

1. /!\ If the PC crash and reboot, your OC settings are too high
2. > More you will increase your GPU power, so win more
3. Install "MSI Afterburner"
4. Set settings as following
5. Power limit: 100%
6. Core Clock: 1000 MHz
7. Memory Clock: + 1500 MHz
8. Fan Speed: Auto (or manually for a more aggressive curve)

RIG

1. This is a computer, which via dedicated software will allow you to mine crypto currencies, and therefore earn money even while sleeping, but consuming electricity
2. > You can recover parts from your old PCs, but some are specific

Build up your equipment

1. /!\ It is very important not to undersize the power supply to be sure that everything can run at maximum
2. /!\ The more recent and powerful the GPU model, the more you will earn while consuming less, but the more expensive it will be
3. > Try to find Molex 4pins - 6 pins GPU adapters to connect them to your power supply for safety. Sata connectors are not made to handle the watts of a GPU, risk of fire
4. One motherboard - with as many PCI-e ports as needed and one HDMI port – 100€
5. > If you take an Asus B250 Mining Expert and you have a black screen, then you must surely use a CPU of too high a generation and the BIOS is not up to date, so you will need a CPU of a generation lower to start, make the update and after being able to put it back
6. /!\ The windows driver can only support 8 cards at most, the mining combination of 12 cards is usually (6N + 6A) (8N + 4A) (8A + 4N) (7N + 5A) (7A + 5N)

Build all

1. Mount the structure
2. Insert the processor on the motherboard
3. Screw the cooler supplied on the motherboard
4. Screw the motherboard on the structure
5. Clip the RAM module on the motherboard
6. Screw the power supply on the structure (probably vertically to maximize airflow)
7. Connect the power
8. Screw the SSD on the structure (probably vertically to maximize airflow)
9. Connect the SSD
10. Connect the GPUs to the motherboard via the Risers
11. > The 6 pins connector of the "Riser" must be directly connected to the PSU, because the SATA cable must not be used since it will not withstand the large amount of Watts (will receive 75W and is limited to 54W)
12. Power the GPUs
13. Connect a screen to the HDMI port
14. Install the OS like HiveOS (do not forget to set up a notification system like Telegram)
15. https://hiveos.farm/install/#howto-image
16. > For an SSD you will need Etcher
17. https://www.balena.io/etcher/
18. /!\ Do not forget to copy paste your "rig.conf" file from the website after fill it
19. > You can do it directly on a USB key
20. https://rufus.ie/en/
21. If you are on Windows, simply install remote control software to avoid buying a dedicated screen and make futur access easier
22. > You will just need it once for the first configuration
23. https://anydesk.com/fr
24. OR allow remote access if you are on HiveOS ("Hive Shell Start", then share the console link to yourself)

OS settings

1. Depending on which one you choose, apart from their easy side and all ready, all the tutorials are on the official site and also in videos on Youtube
2. It is even possible to mine several crypto with the same RIG, if you use HiveOS and you define the card (s) used for each miner (respecting the command line syntax)
3. /!\ If you want to prolong the life of your USB flash drive please run logs-off after installation
