[URL=][/URL]Tip #1. [COLOR=#FF0000]Don't fall prey to Cursair's very deceptive"Are you ready for Ryzen" page at http://www.corsair.com/en-us/landing/ryzen

It is is implied that ALL mem on the above page is compatible with ALL Ryzen motherboards. IT IS NOT. No if's and's or but's.

Tip #3. Buy a 2 stick Kit in the capacity with the lowest latencies you can afford. Latency rules with Ryzen.

Tip #4. Ryzen loaded with 4 sticks is locked/limited to 2133(Singled Rank) and 1866(Dual Ranked)
(I am checking into this as it appears it has changed since Pre-Launch Data was available)

Tip #5. If in doubt what IC's are used on your memory sticks go to http://www.softnology.biz/files.html and download the Freeware version of Thaiphoon Burner.

Tip # 6. procODT

Q - Now if I could find some literature on PROC Ohms I'd be happy. How high is reasonable on Ram Ohms?

A - There will be no "reasonable' value.

procODT is derived from many
variables(mem to CPU traces, CPU, Memory, "noise' levels over traces,
voltages etc) and thus EACH Users computer will be different.

Consider procODT to be a tolerance level, in laymans terms.

Two old skool, and now outdated with the settings/options, for reference ONLY.

Those
two pages have great background/info on procODT. But again, since both
are rather dated now, the #'s themselves are ....... not up to date.
Fortunately, their desc of the function IS applicable to today.

Due to todays much improved design and manufacturing processes the #'s used in the above links are now outdated.

RyMem - the easiest way to see if your RAM will work with AM4

      Do you want to buy a Ryzen system but have difficulties checking
if a specific RAM is going to work for SURE? Or vice versa, you already
bought a stick but don't know which motherboards was it tested with?
Look no further.

Use the below tools to find Guaranteed compatible memory for your motherboard.

https://patriotmemory.com/memory-finder/

http://www.pny.com/support/memory-configurator

I've removed Cursairs Memory Finder until such time as they bring it up to date. Currently, their site is missing all manufacturers Z270 and all manufacturers Ryzen chipset compatible memory. That makes it hard/impossible for us Moderators here to discover compatibility concerns that may be your issue.
