Overclocking a Socket 478 Pentium 4 or an AM2 Athlon 64 (which can run 32-bit OS) requires careful voltage monitoring. HWiNFO 32bit provides accurate readings from the Super I/O chip (Winbond, ITE, Nuvoton) that other free tools miss.
This is where HWiNFO shines. The 32bit version can poll sensors from:

On low-power systems, 64-bit applications can be resource-heavy. The HWiNFO 32-bit executable is lightweight, placing minimal strain on the CPU and RAM. This is vital when you are trying to diagnose a machine that is already struggling with performance issues.
If the 32-bit version fails to start or detect sensors:
