Vista 64/MSI P6N/4Gb RAM issue

[Foo]

This is a tricky one...

Just bought an MSI P6N Diamond mainboard and 4 x Corsair 1Gb sticks + Vista x64

If I insert anything up to 3Gb of RAM the system is fine.

As soon as I go for all 4 sticks vista bluescreens on boot and the whole shebang becomes totally unstable and unusable. I think I managed to get into safe mode but that doesn't get me anywhere near fixing the issue.

I've tried all possible setups with the ram and so it's not a faulty stick.

I've manually set the RAM timings to 4-4-4-12-2T at 2.10v as specified on corsair's forums and the sticks themselves.

So I'm kinda left with the belief that either this motherboard can't take 4GB across 4 sticks, or vista has an issue with 4Gb.

The mobo's BIOS update procedure is patently ridiculous so kinda not an option... and returning the board looks like my only option but if I go for another model of board I'm going to run into trouble with a lack of sata headers and stuff ;(

Any ideas?

Are all 4 of your RAM sticks identical? There seems to be some confusion about the slot pairing on this board... I'm still reading for more info.

Yep all the same.

However it could be that I was looking in totally the wrong place for the problem here... I just found an 'optional' update for Vista (KB929777) that seems to have fixed things... this is the first time I've been able to boot into Vista with all 4 sticks.

I just found the same update and was heading back here to post it for you.

I'm more amused by it being optional, and that if you've got a system with more than 4Gb ram you actually have to remove a stick of ram to update your system.

There's absolutely no reason for this year's OS to install with an amount of RAM that we've only been able to put in a system for around 10 years. I mean christ, you can't expect them to keep up with everything THAT fast.
