I currently am using 1GB in my current system, 2GB in my laptop from work. I run some VMware sessions sometimes and those take up some memory. I was just trying to plan out to maybe start with 2GB and then go to 4GB if needed, but like I was saying, I can find 2x512MB packs but not any 2x1GB so I will have the other 2 slots open in the future. It's been about 3 years since I've built a system, and I there wasn't as many different types back then. If someone could post links to 2x1GB packs and maybe some links or recommendations for 4x512MB packs. The 4x512MB packs I will probably OC, so the most reliable and stable is what would be best.
Thanks.
