S. Heenan, I was able to up the fsb and decreased my multiplier to
218x11 = 2398 following your suggestion of changing the Memory
Frequency to 100% instead of SPD, and the AGP Frequency to 66MHz
instead of auto. Now, the Resulting Frequency is at 218 MHz, 218x2 =
436. This works, and I'm running stable. Can you guys explain what
changing the AGP Frequency to 66MHz does? How is this affecting the
aiw 9800 pro graphic card? I think I may be able to push the
multiplier more, but I'll wait until I get a better ps.

Last thing, can you guys suggest a power supply. There are too many
on the market right now, and the research will take days.

As it stands now, here are my new settings:

CPU External Freq......................................218MHz
Multiple Setting........................................... ..Menu
CPU Multiple.......................................... .......11.0
System Performance.................................User Defined
CPU Interface......................................... ......Optimal
Memory Frequency....................................100%
Resulting Frequency.................................218 MHz
Memory Timing...........................................U ser Defined
SDRAM Active Percentage Delay.......6
SDRAM RAS to CAS Delay...................3
SDRAM RAS Percentage Delay.........3
SDRAM CAS Lantency............................2T
CPU VCore Setting.................................Menu
CPU VCore ..............................................1.67 5V
AGP Frequency.......................................66 MHz
Chip Voltage Control.............................+1.6v

thanks for all your help.


That looks very nice.
I suggested setting the AGP to 66MHz as opposed to Auto to know it was
locked at 66MHz. I've found the BIOS for the A7N8X Deluxe has several small
quirks and that's one of them. Setting the Memory Frequency to 100% or Sync
in older BIOS versions was something I'd read about before ever laying hands
on the motherboard.

Since you have a high end PC it seems a shame not to have an equally good
power supply. Add to that the fact that a failed PSU often means damaged
hardware, I'd look into a 400-500W model from PC Power and Cooling, Antec,
or Enermax. Prices range from about $90-180US.

See if your machine remains stable at the above settings. In the interest of
lower CPU temperatures and perhaps greater overclocking, you could try
reducing Vcore to 1.650V or maybe even 1.625V. OTOH, stability often depends
upon the slightly elevated CPU voltage. No hard and fast rule here, since
overclocking is largely a matter of experimentation. Good luck.
