RYZEN DDR4 MEMORY, WHAT YOU NEED TO KNOW!

Not sure what this XMP is Intel stuff is about, I'm running an XMP profile on my AMD system right now

I'm going to take what Gibbo is saying on board and get the best latency I can for probably 2666, maybe 3000 if there isnt too much of a price gap
 
XMP (Intel Xtreme Memory Profile) was originally setup by Intel, AMD had AMP. That's all it is.
It'll be up to mobo manufacturers what they offer, although we may see memory suppliers offering AMP profiles more tailored to AMDs IMC again now.
 
Pretty sure I've used XMP on my old Crosshair 990FX before, it just isn't called XMP.

D.O.C.P, then Profile #1 or something.

Hopefully the Crosshair VI is much the same.
 
christ on a bike i wish i knew what ur all on about with timings latency tightening loosening. im just going to buy 2 x 8gb 3000mhz corsair lpx stick it in and hope for the best :-)

Gibbo does filling all 4 dimms effect overclocking ?

A comment from Asus:

"
I’ve decided to provide some recommendations on DDR4 limitations concerning AM4 currently.

As it stands the AMD code has restricted RAM tuning options which means many RAM kits at launch will not be compatible. This is the same for our competitors also.
What we recommend is the following:
If fully populating a system with 4 DIMMs (2DPC), use memory up to a max of 2400MHz.
If using 1DPC (2 DIMMs) ensure they are installed in A2/B2 and use memory up to max of 3200MHz.

The indication I have received from HQ is that AMD has focused all their efforts on CPU performance so far and will release updated code in 1~2 months when we expect improved DDR4 compatibility and performance."


In short if filling all 4 DIMM's set your speed to 2400MHz and work up from there.
If using 2 DIMM's put them in the A2/B2 slots and a max of 3200MHz should be possible.

In our testing only the Crosshair board achieved 3000-3200MHz, the others were in the 2400-2666MHz range.

BIOS updates will come!
