DDR 2933

[Scary]

Hey guys I'm starting my first new build after 4 years and I have question about the ryzen 5 I'm eyeing on newegg. It specifically states "DDR 4 2933" are they saying its only compatible with this memory or do they mean 2933 and higher? 

 

Here is a great deal on the AMD RYZEN 5 2600X 6-Core 3.6 GHz (4.2 GHz Max Boost) Socket AM4 95W YD260XBCAFBOX Desktop Processor , https://www.newegg.com/Product/Product.aspx?Item=19-113-497
 I found.

No it means it can do DDR4 speeds up to at least 2933. It will do slower speeds absolutely fine, while speeds beyond 2933 are possible but depend on the particular configuration and luck (quality of the CPU's memory controller varies).

It means that anything above 2933 is not guaranteed. You can try higher, but 2933 is the highest guaranteed frequency.

Ah I see. Thx! What speed ram do I need to achieve the 4.2 max boost? Is 2933 sufficient??

The memory speed is mostly independent of the CPU speed. 2933-3200 is the sweet spot for Ryzen performance.

But I'm asking is if get the minimum in your example the 2933 or must I get 3200 to achieve the 4.2 max boost. I basically don't wanna be locked at the base 3.6 ghz speed because the mem doesn't support it.

CPU clock speed have almost nothing to do with memory speed

 

u can run a 2133mhz ram stick and still boost to 4.2ghz

 

your cpu is guaranteed to boost 4.2ghz, AND support up to 2933mhz ram, if it doesnt hit any of those, you may complain to AMD/retailer

Ram speed =/= CPU Clock Speed.

Even with a 2166 u can get the 4.2 max boost.

Ah I got it, thx for the clarification. Seems like I remember years ago when I started this if you tried to OC higher than the mem speed either PC would bootloop/BSOD or simply cap the CPU speed at the max speed supported by mem.
