4GB of ram is fine unless you do serious graphics rendering, then 8GB can help. I have not heard of 1306 nor used it, any chance of backing it up and making it available for download by us?

About the very nice ram your defective board killed, you should contact Asus, they should replace it with something equivalent, as their defective board damaged it, and since your board was tested and confirmed to be defective, the responsibility lies squarely with them.
