I have a few rams in hand, but they have different speeds. I know that combining ram will result in running the slowest speed installed. I need to know which has optimized performance with the rams I have. Out of all the rams I have in hand, the best combinations as following.
1. 1.5gb ram at 400mhz or pc3200
2. 3gb ram at 266mhz or pc2100
Here's other spec other my computer.
OS: Windows xp sp3
cpu: AMD Anthlon64 3500+ 2.20gb
Thanks.
