I am having trouble getting my speed up to 2600MHz and my FSB is only 166MHz when I would like it to be around 333MHz. My current settings are as follows:

A: CPU External Frequency MHz (166MHz)
B: CPU Frequency Multiple Setting (Auto)
C: CPU Freq. Multiple (12.5x)
D: System Performance (Optimal)
E: CPU Interface (Optimal)
F: Memory Freq. (Auto)
G: Resulting Freq. (Auto)
H: Memory Timings (Optimal)
I: FSB Spread Spectrum (0.050%)
J: CPU VCore Setting (Auto)
K: DDR Reference Voltage (2.6V)

When I changed the settings from above to below, my PC won’t boot.
A: to (200MHz)
B: to (Menu)
C: to (13x)
D: to (Aggressive)
F: to (100%)
G: became (200MHz)
H: to (Aggressive)
I: didn’t change
J: has a range of (1.650V – 1.850V) (I left it the same)
K: didn’t change.

Hardware is as follows:

AMD Atholon XP 2600 T-bred (currently at 2.1GHz)
128 kilobyte primary memory cache
256 kilobyte secondary memory cache
ASUS A7N8X2.0 REV 2.xx (A7N8X Deluxe) (board has a FSB of 400MHz)
Bus Clock: 166 MHz
BIOS: Phoenix Technologies, LTD ASUS A7N8X2.0 Deluxe ACPI BIOS Rev 1007 10/06/2003
RAM: PC2700/333MHz (1GB: two 512MB sticks)
Fan: Thermal Take Volcano 9
Ge-Force 4 MX 440 8x AGP (128MB DDR)


Thanks in advance!!!

A> This is dual 166 so it's for 333 FSB.
Lower the multiplier and slowly increase this from 166 up to see what the limits of your RAM are, higher FSB is more important than raw MHZ.

B> What are the options here?

C> Looks like the multiplier,
MHz speed = [FSB] x multiplier
.

.
H> is there are an expert setting so you can set this manually?

J> Gradually increase Vcore for higher overclocks

K> Increase Vdimm voltage (RAM) voltage to get more FSB out of it


I would not play with these before thoroughly reading the mobo manual and something like this:

well your CPU can't take 2600MHz at low voltage, to hit those speeds you'll need a majik chip with WC or a ton of voltage and some really good WC or phase change
