*AMD has said that they are releasing a new BIOS to address the issues here on Sept 10th. Now we are waiting "2-3 weeks" for MB vendors to release new BIOS for their boards. You are welcome to post your results from your testing as we wait. 

This Question/Topic is to consolidate Max Boost Testing/Results regarding the 3900x only. Please do not post if you cannot test a 3900x. If you have any advice on settings please post a pic of your test/results following the guidelines below.

Please only post results. This topic is for proof of results, not speculation.

Please post a picture of your test results if you can or cannot get your 3900x to boost to 4.6 on any core.

Please us Ryzen Master to view your cores. Select "Show Histogram" under Settings.

Be sure to click "Peak" in the "Histogram" section.

Please use either CPU-Z, CinebenchR20, or Geekbench for testing. Remember to run single core test.

Please list your Motherboard, BIOS version, and RAM speed.

If adjusted, please tell us if you used Ryzen Master, Bios setting, or another tweaking tool.

Please list your Highest Single Core MAX Boost

Your pic needs to include Ryzen Master and what test you are running.

If you can get a MAX Boost of 4.6 or higher then please post the information above and what settings you changed to get there.


Why this forum?

There are many people who like many forums who have many different MB's. Everyone involved has an AMD CPU so this is the most common forums between users.

Well, if you (did you try to) adjust (overclock) X, Y, Z then it should work. (?)

Post a pic of your 3900x CPU max boost at 4.6 with the adjustment you advise.

Why these test?

There are common test that should test your MAX Boost. If you have another that will, then post it with a pic of your results. We want to duplicate your results.

Why Ryzen Master and not HWiNFO?

There seems to be a difference in reporting between Ryzen Master and HWiNFO. Ryzen Master is a first party software where as HWiNFO is a third party. I don't know which is accurately reporting so it is safer to go with first party until it is shown which is incorrect.

The images are small and hard to read.

Open the images in a "new tab" and you can view them at full size. If it's still too small, use "save image as" and view them in your picture viewer. If you just click on them they will pop up in a small window.


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: 4.350
