Gee...I've only been building custom PC's for 30 years now. On top of my experience in the Army, and the time I spent in Winston-Salem working for Dell, is that not enough hands on experience to make up for a lack of time to research one specific motherboard?
Wasn't trying to make you look bad, I was endeavoring to do what I've done in so many other forums over the years, which is no less than to give sound advice to those in need. Thus, I spoke in generalities and suggested referencing the manual for confirmation (because Lord knows nobody is always right). If you are going to take things personally, then perhaps you don't need to be posting here.
Additionally, if you
would like to do some research, you could pull up the motherboard manuals of all the boards I've worked with in the last 3 decades and learn a bit about the RAM configurations I'm talking about. DIMM slots 3 and 4 are the traditional slots to populate first when working with AMD chipsets and CPU's. If you read the manual, you will see this is still the case for RAM overclocking with this particular mobo. Conversely Intel has always been the opposite (0&1 or 1&2), which is to say that the DIMM slots closest to the CPU are generally populated first.
Also, I'm not certain that @ Matilda is a "he" so you may want to omit gender references...
