<B>What is CPUVInf?</B><br /><br />
CPUVInf is a tiny, simple and useful diagnostics tool for the Raspberry Pi minicomputer series written purely in shell scripting language. It is compatible with all Raspberry Pi 1 and all Raspberry Pi 2 minicomputers and therefore with all available Linux based operating systems for the Raspberry Pi series. It started off as a small script to read CPU temperature and voltage but has become much more than that.<br /><br /><br />

CPUVInf is capable of reading various system voltages and converting the output into Volt values. Voltage types: core, SDRAM core, SDRAM I/O and SDRAM PHY voltages.<br /><br />
Memory Split<br />
CPUVInf can display the assigned RAM for the internal GPU and system RAM (usable RAM) in MB values.<br /><br /><br />
