ASUS A7V133 BIOS Settings

Gidday all. I just put an ASUS A7V133 KT133A Mobo in my system and whilst I'm familiar with most of the BIOS settings found in 1004 I was wondering if someone knows what the following settings are and how they affect system performance. Thanks in advance.

Memory Data Drive [AUTO]
Options [Auto] [Weak] [Strong]

CAS# Drive [AUTO]
Options [Auto] [Weak] [Strong]

AGP 4X Drive Strength [AUTO]
Options [Auto] [Manual]

AGP Drive Strength P Ctrl [C]

AGP Drive Strength N Ctrl [E]

Cheers

These settings are best left to auto unless you need to troubleshoot ram or display adapter problems. The AGP settings can apparently be tweaked to get a bit more performance.
