-More on this later.
+Though you can easily mix nVidia and AMD in the same rig with Linux, it's recommended to use a different thread for each platform so a Driver crash doesn't bring the whole rig down. It should be noted however, that some mining software have trouble when both architecture are found on the same rig.

+
+#### Undervolting example
+
+1. Display the voltage and core clock table :
+

+	VDDC: 65284 (voltage table entry 5)
+	VDDC offset: -26
+	Core clock: 1250
+DPM state 6:
+	VDDC: 65284 (voltage table entry 6)
+	VDDC offset: -26
+	Core clock: 1275
+DPM state 7:
+	VDDC: 950 (voltage table entry 7)

+	CACLow = 0
+	CACMid = 0
+	CACHigh = 0
+Voltage state 10: 
+	VDD = 900
+	CACLow = 0
+	CACMid = 0
+	CACHigh = 0

+Voltage state 15: 
+	VDD = 1150
+	CACLow = 0
+	CACMid = 0
+	CACHigh = 0
+
+```
+
+2. Assign the choosen voltage (here 950mV, so position 11) to the latest core clock (here 7)
+
+```sh
+./ohgodatool -i 2 --core-state 7 --core-vddc-idx 11
+Core state 7 VDDC: 7 -> 11
+```
+#### Overclocking example

+1. List the current memory clock
+
+```sh
+ ./ohgodatool -i 2 --show-mem

+	VDDC: 750
+	VDDCI: 800
+	VDDC GFX offset: 0
+	MVDD: 900
+	Memory clock: 300
+Memory state 1:
+	VDDC: 65282
+	VDDCI: 850
+	VDDC GFX offset: 0
+	MVDD: 900
+	Memory clock: 1000
+Memory state 2:
+	VDDC: 65283
+	VDDCI: 950
+	VDDC GFX offset: 0
+	MVDD: 900
+	Memory clock: 1800
+
+2. Change the last clock in the table
+
+```sh
+root@localhost# ./ohgodatool -i 0 --mem-state 2  --mem-clock 2100
