post #1611 of 1616
While ryzen has not been released and the motherboards have only been teased, is it safe to say that we can buy high speed ram ahead of time? I know officially AMD looks to support DDR4 2400, but like intel, can we use higher speed ram such as DDR4 3200 and above? I am also looking to upgrade from sandy bridge, but ram prices have only been going up since a couple of months ago, and would like to buy ram ahead of time.

MSI X370 higher end Mobo quoted 2667+ (OC)

Hmm some sites have reported 2667+ to be the max. Why do AMD's chipsets support much lower DDR speeds?

Also, if I purchase say a 3200 or above speed and the max does turn out to be 2667, would I still be ok with said ram?

Intel's 6700K only officially supports DDR4-2133 and the 7700K DDR4-2400. Everything beyond that is considered an overclock and you can't RMA a CPU that doesn't run 3200+. "2667" on AM4 boards just means that is what the motherboard manufacturer has verified as stable with multiple kits and CPU configurations. I would be very surprised if there wasn't enough of a safety margin for the top SKU IMC's to handle DDR4 2800+ with a little extra voltage. If you buy a 3200+ kit (I have 3200 myself in my 6700k build currently) you can always manually adjust the clock rate and timings down for Ryzen.

I would be very disappointed if ram oc is limited below 3000mhz....

Any ddr4 rams at 3200 should have some jedec profile at 2133 and/or 2400

JEDEC profiles have junk timings though. If we had to use DDR4 2400 we would be lowering the timings and running Memtest overnight to get better performance.
