Windows is telling me that I have 8GB of ram but it says that only 3.96GB is usable. To top it off, my motherboard reads 8GB as well but is running in single channel memory mode. What should I do to be able to use all 8GB?
As a side note, my ram is running at 1600mhz instead of its standard 2133mhz. What do I do in the BIOS to fix that?
Make sure you have the ram in the right slots. Usually this is the same colour slot, but double check and have a look at a diagram of your motherboard and make sure they are both in the same channel.
