That seemed to of fixed it..THNX
Whgat exactly is this trick doing that it works now??
The BCEDIT (/3G switch) tweak allows a 32 bit OS to use slightly more RAM (address space) for an application, if the application is large address aware, at the cost of less RAM (address space) for the system (OS) to use. I've read this entire thread three times and you seem to not want to tell us if you have a 32 bit or 64 bit Operating System. Since you state that you used the BCEDIT tweak and it helped for a short while, I'm going to assume you have a 32b OS. This is your problem.
Ordering more RAM is a waste unless you transition to a 64b OS. Since you want to run three screens at high resolution/3D with an SLI config your RAM demands are going to exceed what a 32b OS can provide, unless you turn down your graphical settings and limit your "skins", any third-party utilities and background processes.
If you wish to try other software that will bring your system to its knees and provide additional OOM (Out of Memory) errors, try FSX with a bunch of high-quality add-ons and max graphical settings.
I am also curious how you have your RAM sticks configured. Your Asus P8Z68-V Pro is a Dual-Channel type of motherboard and as such requires a certain amount of RAM in certain slots to operate in a Dual-Channel config. I am pretty sure you don't have four 3GB RAM sticks as most if not all 3GB RAM sticks are designed for a Triple-Channel config. Now you may have two 2GB sticks and two 4GB sticks, but unless you have installed them correctly in your motherboard as described in your motherboard manual you may experience problems. Having three 4GB sticks negates a very nice feature on your motherboard.
