Problems with Memory/Motherboard

[ZeR0x]

Greetings.


One week ago I put together my new computer. I am having problems with it which I have no idea how to solve myself. I've Google'd, asked on a Norwegian forum and so on.
What I have understood so far is that there is something wrong with my RAM or two of my RAM slots in the motherboard. I've tried every RAM component in slot A1, but not the other slots.
What I am worried about is that my RAM slots are broken or something.

My BIOS is set to default.

The problem here is;

Vista won't boot with 6 GB RAM or 8 GB RAM. Vista has no problem booting with 2 GB and 4GB RAM. All the RAM-sticks are equal, bought as 2 separate kits (2x2gb in each kit).
If I boot my computer with 6 GB or 8 GB RAM I get Windows Blue Screen of Death for half a second then my computer reboots and repeats

Speccs if required:

Motherboard: Asus P5Q-E - http://www.newegg.com/Product/Product.aspx?Item=N82E16813131296
RAM: Crucial 2GB DDR2 800 PC2 6400 (8GB all together, currently running 4GB due to this problem) - http://www.newegg.com/Product/Product.aspx?Item=N82E16820148160
OS: Vista Home Premium x64 (Running Norwegian language though) - http://www.newegg.com/Product/Product.aspx?Item=N82E16832116488


Thanks in advance

Check to see if Asus has a BIOS update for your motherboard.

Did you enable memory remapping?

Thanks for the quick response.

I will update my BIOS as soon as I get home from work.

@ghislaing: Please elaborate, I am not the brightest when it comes to BIOS settings

You haven't specified it, but since you have 8GB of memory, I presume that you installed Vista 64. If you have more than 4GB, you should enable memory remapping. In the BIOS, select the Advanced, Chipset, North Bridge Configuration and enable memory remapping.

If you need to update your BIOS, download it to a USB drive and use the Asus EZ Flash 2 from the BIOS Tools menu. This probably is the safest way to update it.

Did specify it, not that it matters though as you answered greatly.

Will update my BIOS as soon as I find my USB drive.

Will be back with the results.

Updated my BIOS.

Shows all my 8 GB's of RAM now.

Thanks for the help!
