Tested by Bret Weber Last updated 25 June 2026

Stock clocksvsCPU +100 MHzvsCPU +200 MHz, RAM +50 MHz

What's Different

The same Raspberry Pi 1 (Model A+), benchmarked in 3 setups.

Clock Offsets

Stock clocks (Standard): Stock clocks
CPU +100 MHz: CPU +100 MHz
CPU +200 MHz, RAM +50 MHz: CPU +200 MHz, RAM +50 MHz

Tested

Stock clocks (Standard): 24 June 2026
CPU +100 MHz: 30 June 2026
CPU +200 MHz, RAM +50 MHz: 30 June 2026
