I bought some of the Patriot red ram 2 x 4GB 1200MHz as this is the new ram for both intel boards and Ryzen. I have some of this in an X299 and it is really nice. So I sold the Corsair Platinum 2666 4 x 8gb and right now I have only two sticks of 4GB 1200 in my 5820K Asus AII and I was doing memtest and got AE(after doing intel burn test I got a 40 code) code but the ram had no errors sais memtest. I had just loaded windows 10 and it was not the update version that windows 10 always does, sort of like another service pack. I started the computer this morning and left it on and went to the store and when I got back the computer was beeping and doing things as it had updated and then I got the AA code and everything was fine. It seems that the new ram needs windows 10 update to run my ram correctly or at least so the code sais so. My MSI x299 does not have a Q code indicator so that is that.
