A7N8X-E Memory Question / Blue Screens of Death

[The Old Man]

I do not know what to say ...obviously we are missing something here...you
are both running certified RAM for these boards?...I am runnig a config
they
say shouldn't work and it does...3x256 most say not too.
A7N8X-deluxe rev 2.0 UBER BIOS 1007
AMD BARTON 2500@200x11(V-core1.70)
OCZ PC3200EL 3x256 (2.7 v)
Audigy2ZS
ATI9600XT
Lite-on DVDRW
LG52X
SATA120 Max as Prim
Max 30 as B/U
Enermax 465FM
Tt Volcano11(CPU Idle 33 degrees)
am still playing and my kids system is built on an A7N8X-X..it is OC'd too

see if APIC is enabled in BIOS..if it is try disabling...play with some of
the settings...APIC controls the advanced IRQ table.I can not install XP
on
this board if it is enabled..disabled it gives an IRQ table only to 15
instead of 23..is a random issue for the boards

Well at the moment I need to do some further testing but haven't had time -
I was hoping my son would be here to test it out by playing games on it for
hours on end! However last time I tried it seemed okay. On the RAM question,
one stick was specified by Crucial via their Memory Selector, the other was
from an older board A7V333 but still a DDR400 stick, same memory timings but
double sided (chips on both sides). The use of the updated Nvidia drivers
seems to have cured it for now but as I say it needs proper testing.

that other stick could be part of the issue..the double sided one..I believe
they are read different..it might have no errors but could still be causing
the problems.

Yes I wondered about that too. I had the PC for 6 hours today and it seemed
fine with the latest Nvida Drivers.

I have 2 HDD's installed. The new SATA as main C drive with Win2K install and a older 15G
IDE for file storage.

Finally got the PC running. Turned out to be a bad stick of RAM. *head slap*
How did I miss that? Well I had put in 2 sticks of RAM from my son's PC to test it.
Afterwards it turns out he also had one stick of bad RAM. It wasn't bad in his PC but only
after trying it in the new one. :-\

So both times when I checked it I had a bad stick in it so it looked like something else.

My hint was that when I memtested it, I only got one error once and couldn't reproduce the
error.
Also used Prime95 for testing. When I had the bad stick in, the PC ran a test for ummm .4
seconds before crapping out. That was a strong hint.

Finally installed my only stick of 512M RAM that I didn't want ruined and PC ran fine for
a whole night.

Bought new stick of 256M Crucial PC3200 (cost savings :-\) and PC is running fine.

When I tried to put my sons "bad" RAM back in his PC, that worked in the A7N8X-E board,
insta-BSOD in his A7V266E. I have left it out for now then.

Anyway, thanks to all for you help and support. Many lessons learned.

Great news - glad you got it sorted!
