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 :-)

Hi,

Welcome to 7 forums

In this regard, i guess the problem is with the 2 GB RAM or the RAM slot. The issue is not with Windows 7.

► Lets say RAM 1 works, RAM 2 caused the issue.

* To find if the defect is with that RAM or the slot, remove the working RAM 1 and place the RAM 2 in that same slot.

* If your Windows works fine, then the problem may be with the other RAM slot. If the RAM 2 causes BSOD now, then the issue is with the RAM. You may have to replace that RAM 2.

* Additionally, you can try interchanging the RAM slots and boot up !.

Hope this helps

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 ?

Sounds like it's most likely faulty RAM...
Download and burn to disc a copy of Memtest86 then run a test overnight.

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.

Have a look in the motherboard manual also, some boards will only like to have RAM in say slots 1 & 2, 1 & 3, 3 & 4 for example.

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.
