I tried Gigabytes Easytune 5 last night with me GA-965-s3 and an E4300 chip but it locks up on the most minor change. Is there something that must be set before Easytune will function? Ps I can change the voltage but not the FSB.
Stick with BIOS level overclocking. Software overclocking suites may be viable in the near future (eg AMD's Overdrive) but most just don't have it right yet.
