Spec:

Vista 32-bit Home Premium
Cooler Master Cosmos Silver 850W

Q6700 2.67MHz
Asus striker 2 formula, nForce-780i SLI
XFX GF 9800GX2
Corsair Dominator TWIN2X85 2x1GB
WD Raptor X
Creative SB X-Fi Xtreme Gamer Fatal1ty Professional

My PC was pre-built and shipped with 2GB RAM but i wanted more than that, so i bought another pair of identical Corsair Dominator set.
I figured it was easy right? Just plug those two in my PC and i should have 4GB.
That's when i discovered the horrifying world of 4x1 RAM sticks...
My PC froze everwhere. And i mean everywhere. From the startup windows logo to desktop. Hell, it even froze once when i initiated windows safety mode...

Apparently with more sticks = up the vdimm and less timmings.
I looked at what others have done and changed my vdimm to 2.2v and 5-5-5-15-1T (4 sticks = 1T right?)
Unfortunately my PC auto-restarted before even getting to the windows logo. And 2.2v was the most recommended vdimm settings...
I tried 2.1v and 2.0v and that didn't turn out well. So i changed it to 2.3v and imagine my surprise when it worked!
After 10min though my PC died. After rebooting it again i read that it apparently had overheated... -.-

So do you guys have any idea on how i should solved this? At this point I don't give a crap about overclocking anymore, i just want a functioning PC with 4GB RAM.
Is the problem really vdimm and timming? Should i just keep testing between 2.2-2.3v?
If 2.2v doesn't work and 2.3v is overheating, then anything in between can't be much better either right?...

I should mention that 2GB works perfectly. At least everything besides my Sound Card but that shouldn't be a RAM problem...

alot of the time you have to increase your northbridge voltage a tweak to run four sticks of ram

I would not go any more than 2.1 volts on the ram and you dont need to loose timings

where you overclocked at the time of adding 4 sticks of ram ????


if so / then most likely thats your problem >>>> you have to start from scratch on overclocking when you go to 4 sticks

two sticks overclocks alot easier and higher >>>>> four sticks can be done too; but its finickier thats all

reset and clear your cmos / then up your vdimm to 2.1 volts / then up your northbridge voltage by .025volts at first >>>>> watch your system board temps with sensorsview pro

one other possibility is that you are running vista 32 home premium. You will not get the use of 4 gigs of ram. You will only be able to use 3 gigs.

Some 32 bit systems will become unstable when adding more than 3 gigs of ram.

The only way you can have a functioning pc thats using 4 gigs of ram is to have a 64 bit cpu/motherboard and a 64 bit operating system.

No, i started from scratch. I wrote in my first post that i don't give a crap about overclocking anymore, i just want to have 4GB ram (even though i'll be using only 3).

I'm well aware of that i can only use about 3GB.
But i want dual channel, so 4GB is the way to go, even if i waste 1GB.
