So i recently bought a ryzen 5 3600 (using the stock cooler) and am using it on a new asrock b450m pro4 motherboard which came ryzen 3000 ready out of the box. The performance is great but I have noticed that the cpu does not boost properly. I updated the bios to the latest version to try and remedy the problem but that didnt work either. Running cinebench r20 all cores boost to 3900 mhz (it hit 90c during this bench so im guessing thats why it didnt boost), and i get a multiscore of 3500 which I think is in the same ballpark as other 3600s. Userbenchmark tests also say its a good chip. Occasionally it will boost to 4.1 in the desktop but while gaming (csgo and pubg), only 1 core will boost to 4050 mhz and the rest are in the 3000-3800 range. Temps arent an issue when gaming as it only gets to 70-72c in pubg and csgo. Is something wrong with the chip or is this standard? FYI, I am running it in windows balanced mode with 85% minimum processing power which i think is recommended. I can provide any additional info if needed. thanks!

Is it 3.9GHz exact? Or is it 3.9xxGhz? All core boosts, out of the bost is 3.9-4.0GHz, IIRC.
Temperature/voltage headroom, alongside VRMs will dictate what you can get.

4.2GHz is only 1-2 Cores, I believe. The Windows "Balanced" plan might be limiting you too - worth enabling "high performance", at least temporarily to verify.

What are your full system specs?

Here are my specs: https://ca.pcpartpicker.com/list/DfmY6s (i reused some of the components from an old build; the case, PSU, ssd/hdd

Just an update; I just bought a new wraith prism from kijiji for 20$ and temps went down ALOT. Now in cinebench it goes up to 73c instead of 90c! All cores boosted to 4000 mhz aswell during the test and my score is now higher!

My 3600 wouldn't even work in precision boost overdrive mode. I kept getting a BSOD. I gave it more voltage and it still blue screened occasionally. So I sold the thing and I'm switching back to intel.

Pbo barely makes a difference though but i think that will change with new bios versions. If you went with a current gen i5 you will regret it in a year or two. 6 threads just wont be enough and arguably isnt anymore (i5s face stuttering in a lot of games)

Yes this is a well known issue. A lot of people are having problems hitting boost clocks. It's becoming a little bit of a scandal actually because the number of people hitting max boost appears to be low.


Boost clocks are an opportunistic algorithm based on a secret sauce of parameters. One parameter appears to be the motherboard in question. A second parameter is CPU temp. Another parameter appears to be how many cores are being maxed out. Less maxed out cores = higher boost. Make sure you have the latest windows scheduler patches, and PBO on in BIOS. Also try liquid cooling, or being more aggressive on your fan curve. That's about all you can do.

Now Intel does something similar. However it appears AMD is having a lower hit rate than equivalent Intel processors in terms of boost. (Based on informal data.) However the ratings do not change and AMD is still more than competitive than their equivalently priced Intel parts.

Ya im starting to get that feeling. Its unfortunate that there is such a huge variation in chips. And only 1 core even gets close to the boost clock. I am still really happy with the performance though especially now that i installed a wraith prism.

Is there a difference between doing it in ryzen master software? I tried it in the software and it barely made a difference.

No not really. It's kind of a balancing act now. Believe it or not, running at a lower voltage may get you higher clocks. The only way to find out it to adjust the voltages up and down and run benchmarks over and over and over. (stablity: Prime 95 for example, or speed: SuperPi) You'll also need to adjust load line calibration. Overly aggressive causes a quick voltage spikes which generate heat. Under aggressive causes crashes.

I'm going with an i7 9700K.

AMD announced that they were going to fix the boost issues with bios revisions. They are currently working with board partners and implementing the fix and took full responsibility for it. (The 9700k imo is a ripoff as it has 4 less threads and is only 13% faster than the 3600 but almost double the price at least where i live...)
