I own an ASUS M415D with AMD ATHLON. At first, my RAM was only 4GB, but I read online that the maximum is 12GB. I upgraded to 8GB (dual-channel) and checked CPU-Z, which shows FSBBig GrinRAM Async. Was I selecting the wrong amount or should I stick with 4GB+4GB?

RAM and FSB operating asynchronously doesn't always cause a problem; it just indicates their timing isn't perfectly aligned. Typically you'd notice a ratio like 1:12, where the FSB runs at its standard speed and RAM at a higher rate—say 1200 MHz for the FSB and 2400 MT/s for RAM. They probably still function correctly, though the timing difference means slight performance variations. In dual-channel setups, you might see around 4+4 GB using two channels and the rest in single channel. It's not ideal for maximum speed, but it should still be better than a single 8 GB module.
