Hi, I bought a set of these (https://www.newegg.com/Product/Product.aspx?Item=N82E16820236164) a year ago and I am using them currently. I want to get another pair and didn't know if they would work with the set that I am using. I looked in the Memory QVL (https://www.asrock.com/MB/AMD/X370%20Killer%20SLIac/index.asp#Memory) and the manual but it didn't say anything about quadchannel or 4 sticks of RAM being used at the same time. Would they work or would it be best to save up for something else? If buying something else, what would you recommend (PC parts-wise)?

Edit: Okay, turns out that I didn't read the manual well enough and I found my answer! I can put 4 of the same ram (4x8GB) at 2400Mhz in single rank mode for each slot. Thanks for looking anyway!
