[SOLVED] 3900x will not Max boost on any core to 4.6Mhz

[Tarvaln]

Cannot get any core to Boost to 4.6 on any setting. ALL set with Ryzen Master. MB: Asus Prime x570 Pro BIOS: ver 1005, RAM: G.SKill 3200c14. Highest MAX Boost: 4.367

I think this is an issue with the 3900x only. I've created a consolidation thread for 3900x only test for Max boost here. https://community.amd.com/message/2927219

If you have a 3900x and want to test, please follow the link above and post via the guidelines in the topic.

Thanks.

It's common for all Ryzen 3000, but probably more so on the 3900X because the rated boost speed is so high. It seems like I heard there was an option in BIOS that could be changed from Auto to Enabled that will help, but I can't remember what it is.

You're lucky your CPU doesn't auto clock itself to 4.6Mhz. I don't even think you could post to BIOS with that let alone do anything else

You should take a look at this:

I haven't really seen it either with my 3900X.

Look for it (one or tow cores near max advertised boost) merely when opening/closing single threaded apps like Notepad, task manager, etc; as Cinebench is high threaded, you are more likely going to see the all-core clocks at 300-400 hundred MHz lower clock speed, vice a single core at advertised max...

HIs takes (my interpretation of them, anyway!): take the later AGESA, even with slightly lower thermals/boost clocks...

Forget PBO for now...and certainly forget overclocking...(especially with a 3900X)
