#### Introduction
In this tutorial I'm going to explain an advanced settings for NiceHash Miner Legacy as well as the benchmark time limits It will be in addition to the tutorial that I've explained before. I will explain each function in detail and the way it is recommended.

#### What Will I Learn?
-  Advanced Settings
- Recommended Settings
- Configure Advanced settings by editing config file

#### Requirements

- Windows 10 or 8.1 or 7
- RAM 4GB (at least)
-  CPU (AMD - INTEL)
-  GPU (AMD OR NVIDIA) Must be supported by [nicehash](https://www.nicehash.com/profitability-calculator).
- Text Editor (Notepad++ for example)

#### Difficulty
- intermediate

#### Advanced Settings

Open your NiceHash miner legacy.
Then click **Settings** button

An explanation of each function with its location in the config.
``` NiceHash Miner Legacy > configs > General.json```
Note: if the value below isn't exist. you can add it to the object.

> [s] = Seconds

- Minimum Idle [s]
When StartMiningWhenIdle is set to true, MinIdleSeconds tells how many seconds computer has to be idle before mining starts.

Parameter ```MinIdleSeconds```
Value ``` Number ```

- Miner Restart Delay [s]
Amount of time to delay before trying to restart the miner.

Parameter ```MinIdleSeconds```
Value ``` Number ```

- Switch Minimum Fixed [s]
Fixed part of minimal time (in seconds) before miner switches algorithm. Total time is SwitchMinSecondsFixed + SwitchMinSecondsDynamic.

Parameter ``SwitchMinSecondsFixed``
Value ``Number``

- Switch Minimum AMD [s]
Fixed part of minimal time (in seconds) before miner switches algorithm (additional time for AMD GPUs). Total time is SwitchMinSecondsFixed + SwitchMinSecondsAMD + SwitchMinSecondsDynamic.

Parameter ``SwitchMinSecondsAMD``
Value ``Number``

- Switch Minimum Dynamic [s]
Random part of minimal time (in seconds) before miner switches algorithm. Total time is SwitchMinSecondsFixed + SwitchMinSecondsDynamic. Random part is used to prevent all world-wide NiceHash Miner users to have the exact same switching pattern.

Parameter ``SwitchMinSecondsDynamic``
Value ``Number``


- API Bind port pool start
Set the starting value (default is 5100) for miners API ports. When a new miner is created it will use an avaliable API port starting from the ApiBindPortPoolStart and higher.

Parameter ``ApiBindPortPoolStart``
Value ``Number``


- Miner API query Interval [s]
Amount of time between each API call to get the latest stats from miner.

Parameter ``MinerAPIQueryInterval``
Value ``Number``


- Ethminer Default Block Height
Set ethminer DAG mode generation 0 - SingleKeep, 1 - Single, 2 - Sequential, 3 - Parallel.

Parameter ``MinerAPIQueryInterval``
Value ``Number``

- Switch Profitability  Threshold
Miner will not switch if the profitability below Switch Profitability  Threshold. value is in percentage between [0 - 1].

Parameter ``SwitchProfitabilityThreshold``
Value ``Number``

- Dag Load Mode
Here you can chose Dag load mode for ethminers.
Set ethminer DAG mode generation 0 - SingleKeep, 1 - Single, 2 - Sequential, 3 - Parallel.

Parameter ``EthminerDagGenerationType``
Value ``0, 1, 2, 3``


Example for **JSON** object ```General.json```
```
  "SwitchMinSecondsFixed": 90,
  "SwitchMinSecondsDynamic": 30,
  "SwitchMinSecondsAMD": 90,
  "SwitchProfitabilityThreshold": 0.05,
  "MinerAPIQueryInterval": 5,
  "MinerRestartDelayMS": 500
```

#### Benchmark Time Limits

![Sketch.png](https://res.cloudinary.com/hpiynhbhq/image/upload/v1515959351/enkjpqhktipsfx8c4jr7.png)

That Section Created to allocate time limits for [benchmark](https://utopian.io/utopian-io/@jinzo/nicehash-miner-legacy-for-dummies-2-benchmark) proccess.

if you set a number for a parameter that is in NVIDIA Section for example it will apply on all NVIDIA devices not just one device.  if Benchmark  goes beyond that value it will stop there and save that hash rate then it will switch to another algorithm and so on until its finish all algorithms.

for example **Quick** max timeout is ``20`` seconds. so the benchmark process can't take more than that for each algorithm.

The highest **hashrate** in that time cycle will be saved.

Edit ``General.json`` to set values or by using the interface.

```
  "BenchmarkTimeLimits": {
    "CPU": [
      10,
      20,
      60
    ],
    "NVIDIA": [
      10,
      20,
      60
    ],
    "AMD": [
      120,
      180,
      240
    ]
```


#### What's Next?
I've explained a large part of NiceHash Miner Legacy in this series and we almost have finished all functions I think I will be waiting for the upcoming releases because new features will be released and I should talk about them. in the up coming tutorials.
