Can someone either explain these bios features or point me to a reference?

1 What are each of these features?
2 What do they do?
3 When should they be adjusted?
4 When they are adjusted, how much?

• CPU VTT
• MCH - (I know this is the northbridge but question 4 is still an unknown to me)
• ICH
• ICHIO -(again, I know this is the sourthbridge but question 3,4 is still an unknown to me)
• DDR2 Reference volts i(in percent)
• CPU GTLREF 0&2 (67%)
• CPU GTLREF 1&3 (67%)

Thanks!

Found some info...

vcore 0.850 / ---- / 1.500 / 1.550
Processor Core Supply Voltage, applies to E4000, E6000 and Quad Core Processors

ddr2 see specs of your memory modules for voltage ranges
Memory Supply Voltage

mch 1.25v 1.188 / 1.25 / 1.313 / 1.375
MCH Core Supply Voltage (Northbridge)

ichio 1.5v 1.425 / 1.50 / 1.575 / 2.100
1.5V Supply for Logic and I/O (Southbridge - Internal Logic and I/O Buffer Voltage)

cpuvtt 1.140 / 1.20 / 1.260 / 1.320
System Bus Input Supply Voltage, often referenced as FSB termination voltage (VFSB) simply the voltage the fsb is running on. logic levels on the fsb are relative to this voltage. higher vtt results in higher logiclevels and thus in increased noise ratios. increasing vtt might help overclocking.

ich 1.05v 0.998 / 1.05 / 1.102 / 2.100
1.05V Supply for Core Well Logic (Southbridge - Internal Logic Voltage)

all voltage values: min / typ / max / absolute maximum

Heres some stuff I read a while back that may help out a little for a couple of them. Other then that you got it about right.
