run memtest86, it might be that one of the sticks is bad

one of the sticks might be bad. have you tried looking in the bios for any settings you have to turn on when you have 4 gigs?

I saw something in a review at Newegg that might be the problem you describe. Looks like Microsoft may have a patch. I wouldn't know - I have neither 4 Gigs nor Vista. Hope this helps.

"I had a problem getting vista ultimate to work with 4GB of RAM and the nvidia RAID setup. I was getting BSODs. I ended up starting with 2GB of memory, setting up raid in BIOS, installing Vista x64, then applying a patch (microsoft kb article 929777 - http://support.microsoft.com/kb/929777). After Applying the patch I added back in the remaining 2GB of memory and Vista x64 booted nicely."

I think I remember reading somewhere that XP allocated memory in a linear fashion. Like it would take the next available space for newly available memory.

Vista randomizes the allocation process, and the article I read speculated that bad ram would show its ugly head with Vista, whereas it would work just fine with Windows XP.

Just my two bits.

I have a similar system to you and 4gigs running on vista 64 bit ultimate - which version of vista are you using, and it is 64 bit correct?

Mine has no issues and has had no problems since RC1 on my machine in my sig.

 

[crazypyro]

some people have reported Vista 32bit has issues addressing 4gigs much like XP did, others said they had no problem.

Might want to check chipset drivers or BIOS version

Hey thanks Guys for all your help
Ive ran the patch http://support.microsoft.com/kb/929777 and it still not cooperating Ive tested each stick of ram one by one all seem to work just fine i have latest chipset drivers or BIOS version

still not working anymore suggetions ?

 

[human_error]

Which version of vista and are you running 32 bit or 64 bit - this could help find where there may be a compatability issue.

I'm running Home Premium 64 Bit

I just ran an all night MEMTEST no problems with the memory

Well theer should be no issues running it as you have a 64 bit OS.

Try changing your BIOS settings around - i had an issue with one of my overclocking settings and 64bit vista using all 4 gigs. If you have overclocking turn it all off and test it. Also look at your system spec in the bios - i had mine saying 4 gigs installed, 3 gig useable. Also a symptom of this was my 512mb graphics cards had 1.6gig ram :|

 

[Zigg]

Ive turned everything back to default it shows 4096 installed and 4096 useable hmmm weird

 

[human_error]

Yeah, sometimes mobo's don't allow all the RAM to be used when certain overclocking is enabled, just overclock slowly checking all the ram is useable each time, i only had 1 minor feature to disable to enable all 4 gigs for me.

 

[Zigg]

it run 4 gigs just fine on my XP drive no problems. I wonder if i should run a Vista repair :?: HMMMM

right on thanks again

looks like I'm doomed for now I'll give it a rest now let some of my hair grow back that I've been yanking out over this.

so next question is it better to run 2 gigs in dual channel or 3 gigs in single ?

I found another Microsoft patch that seems to apply specifically to nVidia chipsets and 4GB on Vista. Maybe the chipset's the difference for people that have no problems? Since human_error is running Crossfire, I'd be willing to bet that's not on an nVidia board.

Indeed, i use a crossfire ATI 3200 G580 chipset, which has no problems at all

Hopefully all the nvidia issues with vista will be sorted out soon.
