I've had the 1700, 1700x, 2700x, 3700x and now the 3900x, and I've never gotten the clock higher than baseline. I am using the AMD High Performance power plan. Taskmanager sayeth:
AMD Ryzen 9 3900X 12-Core Processor
Base speed: 4.00 GHz
Logical processors: 24
L1 cache: 768 KB
L2 cache: 6.0 MB
L3 cache: 64.0 MB
Speed 3.96 GHz
Up time 0:00:06:20
No matter the load (CPUStress, working, whatever), the CPU stays at 3.96Ghz.
I also tried using the ASUS tool TurboV EVO and clicked the "auto tuning/auto system level up" and it did nothing. I've reset/flashed bios multiple times, just in case that was it. Does this have something to do with 3200mhz memory, or gpu pci speeds or what?
My detailed system specs are here:
I've been building my own systems since the early 90s, but never ran into this type of behavior. I assumed AMD would boost based on load, but the clock speed appears to be totally stagnant. Normal? Not normal?
I didn't think I'd need to tweak bios power /etc for turbo to kick in.
Anyone have any ideas?
