Good day,

I recently built a new computer currently have a ROG CROSSHAIR VII HERO (WI-FI) with a 2700X Ryzen.

I started with two sticks of: G.SKILL Trident Z RGB (For AMD) 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3600 (PC4 28800) Desktop Memory Model F4-3600C18D-16GTZRX. Link: https://www.newegg.com/Product/Product.aspx?Item=N82E16820232728

I was able to set D.O.C.P at 3600 and it all ran fine, today I dropped in another 2 sticks and I keep getting a F9 Q Code. Until I finally bumped it down to 3200.

***UPDATE now at 3333***

I've done multiple searches and cant find anything simple enough for me to understand, such as setting the cold boot at 1.400 ( I tried where I though it was but did not work) I am a quick learner though!

Does anyone have any suggestions, please and thank you in advance!

I have the same board, same memory kit. with a 2700X. 3333 is about all I could get too. I've tried everything with a variety of voltages over multiple bioses. It's well known that 4 sticks is going to have a hard time on the ryzen platform and the performance difference between 3333 and 3600 isn't that much.

The more sticks you add, the less likely you are able to run high frequency.
