Whats going on with zen 2 boosting?

[Kevin Parsons]

Hey guys, just got my x470 gigabyte going with the 3900x. Boosting up until 4200 on all cores so far it seems. I guess we are being held back by Bios currently? Just posting up as I havent got chance to sift through reddit until tomorrow

This is holding me back from buying a 3900x. I'm upgrading from 2700x so it's a bit of a "vanity" upgrade as it is, particularly due to the fact that my use case is overwhelmingly gaming. If the new CPU can't hold its advertised boost clock then I can't convince myself to buy it.

Hopefully this improves soon.

cant you just keep the top speed constantly ? so if your chip does 4200 cant you just have it run that all the time ? im not a eco warrior just want maximum speed at all times. this is possible yes ?

We need motherboard and BIOS used to be able to see if there is an issue there.
Do you use Nvidia GPU also?

Do you try to overclock from BIOS or using Ryzen Master? Have you installed the latest AMD chipset drivers?

Some settings maybe.

Thanks Panos. It's an x470 Aorus gaming 7 wifi board. Latest bios F40.

Update... It's the mobo bios I think. Options seem to be to wait, or attempt to integrate microcode into older versions (not up for that i dont think!)

That would be hilarious. Imagine seeing that on the news. Protests in the streets over overclockers for not saving energy. The way how most of the madness is today.

did you follow all the steps properly? It does matter.

1. If you are using Q-Flash Utility to update BIOS, make sure you have updated BIOS to F31 before F40
2. Before update BIOS to F40, you have to install EC FW Update Tool (B19.0517.1 or later version) to avoid 4DIMM DDR compatibility on 3rd Gen AMD Ryzen™ CPU

Yep, to the letter. Hearing some odd stuff about the v 1.0 of the board hitting limitations and the 1.1 not. I imagine an agesa 1.1.0.3 bios will be imminent and should help things.

3900X is 3.8GHz to 4.6GHz

4200 all core boost is correct.

At lower thread counts the clock speeds increase to the maximum clock speed at one thread.

Yep that makes sense. However, I limited a cinebench to 4 cores and also observed the same. Still convinced something isn't quite right yet!
