I cant get my 6 GB of corsair 1600Mhz memory to show it says i only have 4GB... also Fallout 3 and the DLCs are giving me a ton of ***. on canirunit.com it says its my OS and only my OS (((everything in my rig is over kill for thi game))) so it cant be my parts. and it cant be the OS because ive played it perfectly fine 2 times just testing it. all the DLC's popped up when i got out of the vault and everything... OR should i just buy the Fallout 3 GOTY? insted? and if so would that even work? PLEASE HELP

I'm having a hard time understanding what you're asking. Are you asking why Windows only shows 4GB of RAM? Above you state that you have a 64bit OS so that would lead me to believe that you may have a bad RAM module. I would swap out each module until you can find the bad one.

The other reason why only 4GB is showing up may be because you might have a 32bit version of Win 7 installed instead of the 64bit version.

Here are some steps to see if you really have a 64bit OS.

Go ahead and check that out and let us know if indeed you really are running a 64bit OS. I also am running Fallout 3 on Win 7 64bit and I haven't had any problems at all. It runs just as well as it does in Vista 64bit.

i know it is 64 bit because it says it is in my computer properities and ill try that with the ram... and what settings do you play fallout on? and did you also install the DLC? and do you have it for steam or the disks?

Fallout 3 gets random stutters, but that is related to the drivers. I'm going to roll back to the 185.xx drivers so it doesn't stutter. I haven't had time to play it so I haven't did it yet. It seems my FPS don't go higher than 60 even with V sync turned off. It's always on 60 and only drops below when it stutters a little. Try older drivers.
