BF4 DirectX Error - Out of Memory

I think I've found the solution...

My graphics cards 2x GTX 670 are having this issue, who would have thought with two cards I'd get this... What I have found is that the system memory combines with GPU memory, each of my cards is 2GB, but in SLI only 2GB can be used. There is another 2GB of shared memory in windows for video memory. My rig has 8GB total memory, when playing BF4 I have system monitoring tools watching my system usages. When I play I am typically at 4 to 5 GB used memory, but when I have a few applications open it gives me issues when my memory usage gets close to 6 GB...

WHY?

This is because the system has set aside 2 GB of system memory for shared video memory, I get the out of memory error because I have about 6 GB used in system memory including what BF4 uses as standard processing memory... so if I go over 6GB here and have 2GB shared video memory the system memory must take precedence over the video memory thus triggering the Out of Memory error... I'm going to try to add another 8GB of Memory and see if I still get these issues when I get close to 6 GB of memory usage. I'll post when I have tried it out.

I was consistently having issues with this earlier today, then found firefox was using about .5GB of my memory when on battlelog. I switched to Chrome which used about 100K of memory, did nothing else and the game worked, anyone else having these issues try closing down unused apps to save on system memory and see if that temporarily relieves the issue.

I see your system specs are similiar to mine:
