Okay, I'm running the 64 bit version of Windows Ultimate and recently (in just the last few days) added 2 more Gigs of memory to my system. I was originally running 2GB and increased to 4GB. I have a 'gadget' in the sidebar that tells me what my current usage is on both cores of my processor and the memory usage. At 2GB it was always hovering between 30%-40% and doesn't seem to have changed much with the additional ram. Two questions come up. Shouldn't I notice a signifcan't drop with the system running 4GB of ram? Also, I'm thinking the gadget may be in error. Where would I look in Vista to see current memory usage as a percentage? Thanks.
