Why doesn't AMD OC above 4.0GHZ?

[Pachuca]

Does anyone know why Ryzen doesn't go above 4.0Ghz? Why can't the cpu OC to something like 4.6GHZ for example?

Just the specifics of the architecture and process. AMD wanted much higher IPC than their previous chips, and low power consumption - those goals tend to clash with the goal of higher clocks.

 

(for example, you can make a really long pipeline to get better overclocking, but that also hurts overall IPC)

Because AMD considered it a good balance between stability, performance, power consumption, heat output, silicon yelds and headroom. If you get a good chip you can still overclock it yourself to however high it will go, at the cost of power consumption and heat output.

What? They can clock to 5GHz+ but you need extreme overclocking methods, including LN2, over 1.7v and some iron balls.

Because Ryzen was about taking back significant market share in the business desktop, server, lower end consumer, and oddly enough HEDT areas. not enthusiast e-peen machines.  Zen2 or 3 should increase clocks, although probably not as high as Intel.

it doesnt oc that high because of architecture limitations 

amd propose a tock tock tock architecture improvements which will lead to a more refined zen architecture potentially allow for higher clocks, potentially 5 ghz by zen 3

Keep in mind they have a "Zen+, Zen 2, Zen 3" layout to go through with still.

 

That means Zen+ might simply be Ryzen with higher clock speeds.

I just built an x99 platform like a year and half ago. Will probably use it for another two years, but I hope by then Ryzen will be getting higher OC.

Lol a 1600x or 1500x can do that pretty reliably, a 1700x or 1800x could probably do it as well.

 

Ryzen can go to 4.1 on good chips, heard that 4.2 is possible on golden, well cooled chips.
