4GB DDR2... BF3 is utilizing big part of your ram due your GPU has limited of 1GB. note in crossfire doesn't mean you have 2gb, you are still at 1gb shared channel between 2 GPUs.
Windows in 64bit requires min of 4GB ram so that's for general usage such as email, photo editing (simple), some Movie Maker or internet. More intensive requires best at 8GB ram for optimal performances.
This post has so many wrong statements...
An overclocked Q6600 shouldn't be bottlenecking dual 6850s enough to cause the stuttering, especially if it only occurs during BF3. The game just doesn't like Crossfire right now, as even people with SBs clocked @ 4.5+ghz and CF setups are having the same problem.
DDR2 performs similarly to DDR3 when it comes to gaming, so that is a non-issue. System RAM and VRAM have nothing to do with each other, so I'm not sure why you even linked the two together.
BF3 has used up the full 1GB of shared VRAM between my 5770s(1GB each), but I still get smooth gameplay (except the crossfire stutter) despite 100% gpu/mem usage. As for RAM usage, BF3 only uses up 2GB of RAM, while Win7 uses up about 1GB.
64-bit Win7 actually has a minimum of 2GB of RAM, not 4GB. I only use 4GB and have yet to max it out during gaming. (at most 3GB usage)

As well, in other games when you compare a 1GB setup to a 2gb setup and the 1gb is bottlenecking, the game will run fine but perhaps 5-10 FPS slower, not spikes to 0.
Do you actually see your FPS spike down to 0? When I get stuttering, my FPS actually spikes up from 75-90FPS to 100-110FPS.Edited by Kokin - 10/31/11 at 11:25pm
