Windows7 only accept 2 GB RAM

Hello,

By some reason Win7 only wil run with 1 x 2 GB RAM.

First i couldn't install Win7 - i got BSOD wit somthing about VSMRAID.SYS and IRQL NOT EQUAL.
Then I try to remove som hardware, and when I removed one of my to 2 GB RAM, then Win7 was installing perfect.

Afterwods I tryed to inset the second 2 GB RAM again - but then BSoD came again.

What is wrong? Why do Win7 give BSoD?

Win XP was OK with 2 x 2 GB - Why is Win7 not?

RAM: 2 x 2 GB GEIL, PC2-6400, DDR2-800
Mainboard: MSI P45 Zilent/Platinum with the newest BIOS.

Please help me

please can you post your minidump files for analysis ?

VSMRAID.SYS is a VIA raid driver so check that's up to date ?

and I also suggest you burn to CD and run from boot memtest86 for at least 3 passes, with one stick then with both, you won't need to boot into windows at all for this test.

please post results here ?

I will post the minidump - but first, what contain the minidump?

Thanks

First Venths: I have try to have one singel 2 GB RAM in every 4 slot on the mainboard - and Win7 is starting perfect. I have also tryed with the other 2 GB RAM with the same result.
So the RAM is working fine and mainboard too. Byt when have two RAM in 2 slots - then Win7 is crashing.

So the problem is something wit the to RAM in the slots together - nomater is it is in DUAL or not.

I'll find my minidump an post it here.

Orpheous: I have already looked in my MSI p45 Zilent manual. If I will use DUAL for good performance the system is 1 and 3 or/and 2 and 4 - othervise I can place the RAM as I like.

Here is my latest minidump - i hope you guys can help me
