[Solved] Booting with 4gig but only using 2?

I'm on 64BIT vista and I boot with 4 gigs installed but it seems to only use 2 of it



any idea how to fix this?

p.s. I already check the bios and everything says 4 gigs but im running with 2

EVGA 680i 3 way SLI

Intel Core 2 Quad Q8200 2.33GHz

8800GT

I been trying to update my BIOS but im not having any luck with that

From what I have found it appears to be a power issue with the 680i boards.

Here is a post from www.bjorn3d.com forums, by Pablo 54:

I agree with all posts on this. I have put this out before, but to get four sticks of memory to work with a 680i you have two choices: Pump up the juice or drop it to 667. As for two different types, I can’t give you a definitive answer other than to say it probably is not helping the matter.

The OP of that thread, New Madrid, fixed his issue by:

Thanks to everyone who read my post. I started by taking out all the RAM, checking each stick to make sure each one worked. After reseating them, all 8 gigs worked!!! Who knows. - New Madrid

Let us know how it goes. If that doesn't work try each stick individually, then try them in sets of two, see if you can track down if there is an actual problem with the sticks themselves.

You could try reinstalling the OS, that is always an option. But re-seating the ram did nothing? hm.... :::SADFACE:::

Have you tried posting in the memory section?

AHAHHA. really? Simple as that? Hey, good job. You should have marked your own last post as the "Best Answer" solving the problem.
