I HAVE TRIED THE DETAILS BELOW BUT MY SYSTEM THEN SHUTS DOWN RIGHT AFTER I
SAVE THE BIOS AND REBOOT. Any other suggsstions?

This it?You could have searched using Google too....
1.Advanced chipset features >system performance>select Expert( this will
enable all options)
2.CPU clock> default is 17 i think, select 12 or 13(12 is safer)
3.FSB frequency > select 166, as a start(your ram will do 200,but the board
is not guaranteed to reach this.Mine only did 190ish max until i modded the
Chipset(northbridge)voltage.
12 x 166 will give you 1992 Hz(13x166 = 2158)
4.CPU interface>optimal
5.Memory frequency> same as FSB always = 166 in this case
6.mem timings(reading down), 11,2,2,2 your ram should do this at 166 easily
Leave most other stuff at defaults here i think

Power bios Features( this is where you set the voltages for CPU etc)
1. CPU voltage( default is 1.6 i think), select 1.7 or thereabouts(may not
boot at 13x166 with this,but should be ok for 12x166, no more than 1.8V)

What else, oh yeah, with overclocking you are going to see more heat so,
PC health status
1.CPU warning temp > select a reasonable value maybe 50-55C
2.Shutdown temp> maybe 60
i have mine set at 50 and 55, but then i'm watercooling
i think that is it.
exit bios and save settings
if machine does not boot or locks at post, hold Insert and Delete key on
reboot.This will load failsafe defaults, which will allow you to get into
the bios to change to easier settings
Do not quote me on all this :)
If machine boots at overclocked settings, check your cpu temperatures on
post screen and also when you run Windows.This is basically it.
Good luck
you may want to also upgrade to the latest bios for your motherboard, if you
haven't done so.RUN CHIP AT DEFAULT SPEEDS WHEN UPGRADING BIOS.you don't
want any lockups while doing this.

First make sure that the cpu is not multiplier locked.
This web site might help.
http://fab51.com/cpu/barton/athlon-e24.html

If the cpu has a locked multiplier then you will only be able to increase
the fsb.

Get the 8rdavcore 0.88 GUI program. Make sure you install the giveio drive
located at the bottom of the page.
http://www.hasw.net/8rdavcore/

Understand your BIOS
http://www.tweakhardware.com/guide/Epox8RDABios/

Get Prime95 program to test with.
http://www.mersenne.org/freesoft.htm

1. In the BIOS set the memory to run at the fsb frequency.

2. In the BIOS if the cpu is not locked drop the default multiplier down to
10.5.

3. If you can not use the 10.5 multiplier go to the 11 again assuming the
cpu is not locked. This has to do with L12, which won't allow a 10.5
multiplier. Could update the BIOS with a modified version, which will allow
the use of the 10.5 multiplier.

4. Using 8rdavcore increase the VDIMM to 2.7v if the memory voltage is rated
at 2.5v do not exceed 2.9v. Using 8rdavcore set the tras to 11, trcd to 3,
trp to 3.

5. Using 8rdavcore increase the FSB in 10 Mhz increments and use prime95 to
test. (Should be able to reach 166Mhz depending upon your memory.)

6. When prime95 returns an error increase the vcore voltage in small steps
until pime95 will run for at least 20min with out errors. Then repeat step
5. I think that 1.85v vcore is the maxium setting for this board, although
do not exceed 1.9v. Watch your temps, with prime95 running they should not
exceed 57°C for stability reasons.

At some point you will reach the limit of the ram and/or the limit of the
cpu. Try to balance the two using the fsb and the multiplier to achieve the
highest fsb vs. cpu frequency vs. temp's. Document your settings and
findings at each step. Remember to use small steps and test for stability.

7. Once you have achieved for maximum fsb and cpu freq. with 8rdavcore go
into the bios and change the setting to match.

This will take some time. Good luck.

BTW you can look over the databases and see what other have gotten with
1800+ and 8RDA+ motherboard.
