The P4ES uses a very conservatively set up Award BIOS.
It's certainly not very overclocker friendly, but then again the average user
doesn't need these options!
For newbie's who want to tweak their computers, Iwill does give a
full access to memory controls. There are all the usual tweaks we would come to
expect like CAS Latency, RAS to CAS and Memory Frequency. The only AGP option is
setting the AGP Aperture Size.
As we can see here, there are very little overclocking options.
CPU VCore goes up to 1.85V even for Northwood Pentium 4's but the FSB can only be
upped to 132 MHz in 1 MHz increments.
