AMD 3000 users how often do you hit boost clocks?

[Jacky60]

It's been about six months since the 3000 series launched. How many of you guys are hitting advertised boost clocks in games?
Few games, if any tax, a CPU all core 100% so can I have some feedback on how AGESA bios/Pbo etc is working now and whether two or three cores can ever realistically be expected to run at boost speeds in game?

Anecdotally it looks from these results that many of the CPUs are now hitting advertised speeds. However it may be that only owners
of chips that do reach advertised speeds are happy to respond to the question.

My 3900X struggles to hit 4.5 GHz let alone 4.6 on AGESA 1.0.0.4B. Boost was slightly more consistent on 1.0.0.3 ABBA (in terms of hitting 4.5 GHz or above) and Cinebench R20 single core performance was slightly higher (up to 2%) although R15 single core was about the same, multicore performance is slightly higher on 1.0.0.4B though.

However, I can force my best core to hit 4.6GHz+ by running Aida 64 memory latency test or the Crystal Disk Mark SSD benchmark (which results in a couple of cores hitting 4.575GHz too) so technically it is hitting the rated boost clock. Most of the time my 3900X is a 4.4-4.45 GHz chip though.

This is all at default settings (no PBO) on a Noctua NH-D15S cooler with the XMP 3600MHz profile enabled (my scores were worse at JEDEC 2666MHz RAM speed). I have also tested on two different motherboards (an MSI X570 ACE and a Gigabyte X570 Master) with close to identical results.

My Cinebench R20 scores with 1.0.0.3 ABBA:
Single core about 520.
Multicore about 7150.

1.0.0.4B:
Single core about 510.
Multicore about 7300.

That doesn't seem too bad, at least its rocking along at 4.4ghz most of the time which I imagine is pretty good for gaming.
