I just put 2 x Crucial 1GB DDR2-800 / PC6400 Memory in my system. (model
number BL12864AA804.16FA.

Just cant get themto work, they are 4-4-4-12 @ 2.1v, I put these settings in
the bios, and my system just does a long beep, on manual settings, on Auto,
it boots but with in 3 secs a BSOD happens.

BIOS is 0605

System is :-
INTEL PENTIUM 4 3.6GHz HT LGA775 Prescott (660)
Asus P5ND2 SLi Deluxe nForce4 SLi (LGA775) PCI-Express Motherboard
Arctic Cooling Freezer 7 CPU Cooler (Socket 775)
Corsair 1GB DDR2 XMS2-5400 Pro TwinX (2x512MB) Before upgrade
2 x XFX GeForce 7800GTX 256MB DDR3 TV-Out/Dual DVI (PCI-Express) in SLI mode
3dMark 03 17134 / 3dMark05 7571 in NON SLI mode
3dMark 03 27714 / 3dMark05 8866 in SLI mode
AquaMark3 78876 in SLI mode
Pioneer DVR-110BK DVD-R/W
Hitachi 180GB Deskstar 180GXP ATA100 IDE HDD
Hitachi Deskstar 7K400 400GB SATA 8MB Cache HDD
Globalwin GAT-002 Aluminium ATX Case
Enermax Noisetaker 600W EG701AX-VE(W) SFMA ATX2.0 SLI Compliant PSU

Any ideas on what to do. I dont want to go bios 0802 but if needs must, any
one got any DDR2-800 / PC6400 running on this mobo.

Thx
 
did you do a clean install of xp
I upgraded and I didn't and I had problems
I reinstalled xp and it is fine now

The Asus QVL has a very short list for DDR2-800.

This Anandtech article ran the P5ND2 at DDR2-667.

http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2394&p=5

I would manually set them to DDR2-667, unless you can find an
article that lists DDR2-800 operation as stable with the
P5ND2.

OK. At the bottom of this article, it says...
http://www.anandtech.com/mb/showdoc.aspx?i=2412&p=5

"The Asus P5ND2-SLI also had no difficulty in reaching DDR2-800
memory performance. However, one of the marketing points made
by NVIDIA is the 1T Command Rate that can be used with the nF4
Intel Edition at DDR2-667. The P5ND2-SLI does indeed handle
a 1T Command Rate at DDR2-667, but by DDR2-800, a 2T Command
Rate was required for stable operation. On the nF4 Intel
platform, the performance impact of a 2T Command Rate appears
to be rather small, as the nF4 Intel performance remains very
competetive with the 955x as far as it goes. However, at just
over DDR2-900, the nF4 Intel appears to hit a wall - with the
same memories that do DDR2-1000 to DDR2-1066 on the 955x. As
a result, we have no screen captures or results to post for
the Asus P5ND2-SLI above DDR2-800."

If your BIOS has a Command Rate 2T setting in it, enable it.
This setting would be separate from the other memory settings,
and the BIOS has no reason to set it to 2T for you. Normally,
a BIOS would be programmed for 2T when there are four DIMMs
present, but the BIOS may not take all conditions of overclock
into account properly, and use it when it is needed most.

See "Memory Timing Config" in the manual and look for
"Addressing Mode". Try setting it to [Two Clock].

And test with memtest86+ from http://www.memtest.org/ .
Testing with a floppy prepared with memtest86+
is a safer alternative than corrupting your Windows install
by booting and crashing it over and over again. When memtest86+
is clean for at least a couple of complete passes, then consider
booting back into Windows for some fun with Prime95 (mersenne.org).

There is also a version of memtest86+ suitable for making
an ISO CD image. That is for cases where the computer has
no floppy drive.
