Hi
Just thought some of you might like to know about my bios settings. I am
using the AMD Athlon XP 2000+ model 8 Thoroughbred 0.13u rated at 1667 MHz).
These are the advanced chipset features setting.
166 MHz FSB, Menu, 11.O x (this give speed of 1837 MHz)
Optimal, Optimal, By SPD, 200 MHz
Optimal, 8-3-3-2.5T
Disabled, disabled
1.600 V.
I found the lower FSB speed allowed greater CPU clock speed setting without
memory errors. At FSB of 200 MHz I could not even increase the multiplier to
8.5x.
My memtest86 v3.0 results after 1.75 hours of testing were:
13 Passes, 0 errors
L1 cache 128K 11271 MB/s, Memory 256M 844 MB/s
Bios Hardware monitor results immediately following this test were:
MB temp 16 deg C/ 60 deg F, CPU temp 44 deg C/ 109 deg F
VCore 1.61V
CPU fan speed 2909, Chassis 2428
Q-Fan control enabled, Fan speed ration 10/15
Speed up/down response time 4s/8s.
This setup running an S3 ViRGE 4 MB PCI card managed to run at 42.8 fps on
Superscope benchmark.

You should obtain a performance increase by running your memory in sync
with your cpu.

I should probably post this separate but it is in a similar vein.

On my A7V8X-X I find that I can hit higher multipliers if I underclock the
FSB. I'm urnning a 2600+ and can hit anywhere from 2083 (12.5x166
@1.65vcore) to 2434 (15x162@ 1.80vcore) with great stability. Unles I really
want to ramp up performance I tend to leave it running around 2ghz with the
lower vcore.

Just FYI

What memory do you have, Mike?
 
If 2 x 256Mb sticks, I assume you are running dual channel mode? I assume
you are running the memory in sync with the cpu also?

Unfortunately, I cannot get 200FSB on my board with an XP2100 - the best is
2.3 Ghz (185 x 12.5) - not too bad on stock HSF.

I'm with you. If I set memory frequency to 100% than I may get less memory
errors. I'll give that a go.

I tend to get many memory errors (8e and 7f errors) on my A7N8X-dlx system,
are you saying that fiddling with the BIOS memory settings (currently at
default) may improve this?
Also, is 12.5 really the highest multiplier this board will go to? It seems
a little low.

The lower FSBs release the higher multipliers, IIRC. At 12.5 x 200, the
clock is 2.5Ghz, which is higher than any current Thoroughbred or Barton
cpu.
