i still don´t understand why they say in that list the RAM is certified for 3000 MHz and under DOCP it is listed as 2666.

for me it would be logical that a 3000 MHz certified memory is listed as 3000 DOCP.... not 2666.

lets take the first RAM in the list as example, the corsair.

it´ a 3000 MHz branded RAM, so it should OC to 3000 MHz.
it is certified as 3000 MHz in the asus QVL.. but the DOCP says 2666.... you see why i am confused?


ps:

to be honest this RAM stuff is holding my purchase off.
i just want to run 2x16GB at 3000 or better 3200 and nobody, not asus or g.skill (i wrote emails to both) can tell me which RAM i should buy ("we can give no official recommendation" - g.skill. we are working on supporting more memory. the QVL will be updates in the future. - asus").

when the motherboard and RAM maker can not give a recommendation... than who can?

i guess building a ryzen system is stil a lot of try and error when it comes to memory.
and maybe i let the platform mature a few more month.

I hear your pain, man. It's really a shame. Either you have to compromise or you have to take a risk.

2666Mhz might be a guaranteed overclock for Ryzen while 3000Mhz is what the kit should hit if all other factors came together. Maybe 2666Mhz is rated for Ryzen while 3000Mhz is the kit's rated speed on a system that supported it fully, such as Z270.

You could always buy a 2x16GB kit that is rated for 3000Mhz and if it doesn't run it at that speed, knock it down until it does. Then when the BIOS' have improved you could increase the A-XMP to 3000Mhz. That's what the majority of people are doing.

someone from g.skill got back to me and told me that the SPD/DOCP column tells me what speed can be automatically set for the RAM by the bios. so even when RAM is certified for 3000 MHz i need to put in manual settings when under SPD/DOCP only 2133 or 2666 MHz is listed. with the DOCP setting alone, i would only achieve 2133 or 2666 MHz.
