AMD OC guide thread

More like an AMD issue for not giving their proccesors a stronger IMC.

understand comment is in jest, however AMD pioneered the use of IMC in CPUs, so much so that Intel had to license the IP from AMD for use in the iCore series.
It looks as though the IMC may in fact prove very robust particularly when looking at the upcoming zen based opteron (8 channel)

Bad choice of wording based on old(er) information on my part.. in the past Single Rank/Dual Rank was commonly used in conjunction with Single Sided/Double Sided ram. In fact "rank" actually refers to how the memory is organized (structured)/accessed.

A rank is a data block typically a width of 64 bits (72 when using error correction)

Dual rank usually = slower due to having having to access 2x

"As an example, say a chip has eight memory lines, eight chips are required to reach the 64 bits. A single-rank module therefore needs eight chips. the same configuration in dual rank, twice as many chips must be present in order to enable 64 bits. For the same module capacity this would require twice as many memory chips with half the capacity would be sufficient to achieve this goal."

Are the (2) 16 gb G.Skil modules I just purchased dual ranked or single ranked? I have no idea.

IF they have the white stickers on the stick/package , look for a 1R or 2R (refer to the 2 links provided earlier, one to Crucial)..otherwise your best bet is sending an email to GSkill with your SKU/product #s and asking.

No word yet if its a limit of AMD's memory controller (on die) or of the 370 chipset (designed by Asmedia), however currently only single sided/single rank DIMMs in Dual Channel mode support 2666+

These are just frequency expectations, not hard limits that have anything to do with the what the ASmedia chipset supports. AMD's guidelines are based on averages across all vendor boards combined - including the "lemons." Overclocking centric boards teamed with a good CPU and memory kit can fare better (assuming the user has some nous).

Is there a way to tune the NB frequency on Ryzen like the old Thuban/Deneb processors? If it were tuneable would it even make any difference on X370?

Yes, it's soldered
No, don't delid your RYZEN CPU
