Zotac Nitro VGA Overclocking Controller

Software

The software for the Nitro is called "FireStorm" and works without the Nitro too, then it is a normal overclocking utility. Once you attach the Nitro, FireStorm will detect its presence and send output to it.


The options are fairly basic but cover everything you would need to configure.

Testing

Whenever the Nitro is idle it will show the main menu. The three text strings at the bottom of the display refer to the action that is executed when the button below it is pressed.
Here you can go to "Set" - which allows changing clocks and fan speed, "Profiles" and to restore the BIOS default clocks of the VGA card.


The profiles management system is fairly basic (mainly because of the limited number of buttons). You can create a new profile which will take your current settings and store them away. By pressing the Next button you will cycle through your saved profiles. The profile's settings will be displayed on the main screen. Once you have the one you want, you just press the apply button and the profile's settings will be applied. Unfortunately naming the profiles is not possible.


Every time you press the Set button, the red arrow will move one step forward. It starts at core clock, goes to memory clock, shader clock and fan speed. Then it starts at core clock again. This is a very intuitive system and easy to use.
Once you are at the desired setting that you want to change, you just press the + or - button to instantly change the setting.


Fan speed can be changed as well. The default is to use the automatic fan speed settings as defined in the BIOS. If you want more cooling performance or a quieter system you can select a fixed fan speed here.
