Which RAM parameters do you use?
With the same board and Corsair RAM (given for 2-3-3-6 for P4 and
2.5-3-3-6 for athlon64), I was working in 32bit with 2 instead of
2.5 for the CAS, but I had to set it to 2.5 in 64 bit.
Maybe you have to relax a bit your timings?
I followed your advice and checked the memory timings in BIOS, I found
a puzzling variaty of parameters, almost all of the were set on AUTO
Here is a summary of the main possible switches:
parameter possible Values help
Burst Length: 8/4 Beats 64-Bit Dq must
use the 4 beats
CAS 2/2.5/3 CLK
TRC 7-13 CLK
TRFC 9-15 CLK
TRCD 2-6 CLK
TWR 2-3 CLK
TRWT 1-6 CLK
TRAS 5-15 CLK
TRP 2-6 CLK
TWLC 1-2 CLK
ASYNC LAT 4-9 CLK
I've corsair DDR in dual channel
I've left the burst to its highest value
I use 2.5-3-3-6-1T
2.5 is CAS
3 is tRCD
3 is tRP
6 is tRAS
1T command rate (Disabled for 1T, Enabled for 2T)
I've left the other "as is"
The processor is an athlon 3500+
It runs at nominal voltage/frequency. But I've not left on 'auto' the
parameters because this card has a nasty auto-overclocking feature.
I've set manually to the nominal values :
I use a FSB of 200, multiplier 11 (If we can speak of FSB with this
architecture).
I've cool and quient enabled
I changed Burst Length to 4 Beats (what t.h. is 64-Bit dq?)
and CAS to 3, left the rest on AUTO but still got the kernel panics
with 64 Bit Kernels.

Jean-Luc, you said you have the same mainboard. What other hardware
do you use? Maybe I can change the grafic card or give up the
software raid to get a stable 64 bit system.
I would like to encourage other members of this list with an Asus A8V
motherboard to report about there configuration so that I finally can
find a way to tell if I have a defect mainboard or an exotic hardware
composition problem.
I've :
2 SATA Maxtor disks on the VIA chipset, software RAID1
1 IDE DVD burner Pioneer 108
1 Asus Radeon A9250/TD (AGP)
I don't use the Promise chipset
I've used a Radeon 9500 also but not in 64 bit. I've given it to my
daughters who *need* graphic power for the games...
The BIOS is 1013
Remark : I have had problems with the graphic mode and some machine
check, even in 32 bit with the previous BIOS. 1009 was "just" working,
it was imposible to have a graphical session with 1011 and 1012, there
is a fix about AGP in 1013.
Best Regars
