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'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 have tried 2x 1GByte Infineon CL2.5 DDR 400 without success, then I
switched to 4 x takeMS PC3200 CL3 which used
to run in single Athlon 2000+ Cube PCs for long without a problem.
I took your advice and made the following settings:
3-4-4-8-1T
1T would not even boot so ich switched here to AUTO and had
3 for CAS
4 for tRCD
4 for tRP
8 for tRAS
but, alas, the result is as devastating as ever, i/o tar test and kernel
compile test runs fine
with kernel 2.6.8 686, when I switch to 2.6.11 amd64 k8 it crashes the
machine within 10 minutes.
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 have the athlon 3200+ and as you I noticed that booting sometimes
stops due to
a message that "Auto Overclocking failed" although nobody tried to
overclock, so I
switched here to manual settings as well.
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 have an old Riva TNT2 MX 64 32 meg and changed it for
an even older S3Trio64 PCI becaused I suspected the Nvida
to be a 3V AGP card but that changed nothing.
I disabled all onboard IDE and used a Promise TX2000 PCI
IDE Card for my 2x300 GByte MD Raid but that changed nothing as well
(allthough I had the feeling that the system lived a bit longer than
usually, i.e. 20 instead
of 10 min.)
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.
I have Bios 1013 as you and up to now I did not try the beta BIOS that can be found on the Asus server.
As mentioned earlier I am waiting for a delivery of 4 x 512 Kingston
Value RAM from the Asus manual's compatibility list.
If that failes too I have to assume that the board is defect. But can
a board be defect in a way that the k8 64 bit kernel crashes and the
686 32 bit kernel works properly?
Seems very strange to me.
