Optimum seetings for A7V8X-X motherboard BIOS with an AMD Athlon CPU

[Patrick Roberts]

I just bought an ASUS A7V8X-X motherboard and an AMD Athlon XP 2800+
CPU. I have the latest BIOS dated 09/02/2004. In the BIOS I have to
set the CPU speed. If I set it to 1667 this will work but the the
ASUS probe software says it's capable of 2250 MHz (I know this CPU is
capable of greater than 2 GHz). When I set it to a higher CPU speed
the system doesn't want to boot. I have not tried the Manual setting
yet as I'm not sure of the other settings in the BIOS. I also don't
see how to set my Frontside Bus to 333MHz.

I've searched the ASUS web site but couldn't find anything.

I would appreciate any help as to the optimum settings in my BIOS to
get the maximum performance. Thanks.

Depending on what 2800+ you have the following are the non-OCed settings:

Tbred (256K cache) 13.5 x 166 = 2.25GHz
Barton (512K cache) 12.5 x 166 = 2.083GHz

In either case set your CPU external frequency to 166/33 since the manual
states that the CPU will run at the 166 frequency time the Multiplier you
set in CPU Speed. I'm almost sure your CPU is multiplier locked so you won't
be able to set this to anything other than spec.

Assuming you have PC2700 (333MHz) DDR memory, set the Memory Frequency
accordingly.
