Memory usage at 98% when playing Battlefield 3 (4GB DDR2)

post #1 of 4
Thread Starter 
Im having performance problems in Battlefield 3 and its being caused by memory. I have 4gb of G Skill PI.Black DDR2 1066mhz RAM, although I run it at 800mhz with 4 4 4 12 timings.

When playing BF3 RAM usage can go as high as 98%, which causes the game and my system in general to perform very badly.

So I figured I can just get some more RAM, problem is they dont make my RAM anymore. So I have 2 questions:

1. Would I be able to buy some cheap ddr2 that is also 800mhz, as long as it had same number of pins, etc?

2. If not, would I see much of a performance decrease if I swapped to some cheap 800mhz RAM with CL of 5 or 6 (baring in mind my current RAM has CL of 4)?
