Should I use Gigabyte Easy Tune 5 Pro?

Hello - I am new to overclocking.

I have a Gigabyte motherboard and a copy of Gigabyte “Easy Tune 5 Pro”. This has lots of funky options such as a “CPU Intelligent Accelerator “ and a “Memory Intelligent Booster”.

Is it a good idea to use this utility (if so what are some good settings) or should I just make changes to the BIOS manually?

My system is:

Gigabyte GA-956P-S3 (revision 2)
Core 2 Duo 6300
ASUS 8800GTS
2 GB memory (2 x PC6400 DDR2 800 1GB)
550w TruePower PSU
Windows XP

Thank you.
