Hey all,

I have seen conflicting information about Ryzen RAM support as well as the B350 RAM support.

Per G.Skill's documentation, the max supported RAM speed with the B350 is 2400 mhz. Per Asus's documentation, the B350 supports pretty much any speed of RAM up to 3200 MHZ. I chatted with an ASUS specialist and they said I'd need a much more expensive motherboard and the Ryzen 1800x.

Also, I've read conflicting information about what RAM speeds Ryzen supports. Some claim Ryzen is flaky with RAM above 2666 MHZ and others claim I shouldn't go for anything less than 3200 MHZ.

On Asus's website, they say they support 2933 MHZ (O.C.) and their RAM compatibility list has a few that are even faster. Does the (O.C.) mean I will have to manually overclock the bus or will it automatically detect the RAM's speed if I get a fast stick? Can the B350 do anything above 2400 MHZ with a Ryzen 1700 rather than a faster Ryzen?

Thanks!
 
On the ASUS website for the product it says the following:
"With DDR4, you'll accelerate memory frequencies up to an incredible to 3200MHz! And ASUS works with almost every DDR4 memory vendor, so you're assured the best compatibility."
Anything above that would have to be the work of custom ram OC.

Per https://www.asus.com/us/Motherboards/PRIME-B350-PLUS/specifications/ , it says DDR4 3200(O.C.)/2933(O.C.)/2666/2400/2133 MHz. The (O.C.) implies that even below 3200 MHz, it would need a custom OC, right? Or am I misinterpreting what the O.C. means?

I'm also still unsure of Ryzen 1700 compatibility with faster memory. I've ready mixed things about Ryzen with RAM above 2666 MHz. Any idea if faster RAM will work?
 



I see. Well in that case, you're correct. The maximum for un-buffered memory (non oc) looks to be either 2666 or 2400.
