Intel Core Ultra Boost capped at 5.4GHz for HP workstations
Intel Core Ultra Boost capped at 5.4GHz for HP workstations
Hi, the new HP Z2 mini G1i workstations with the core ultra 9 285k CPU were installed recently. During benchmarking, I observed that the single-core boost clock is capped at 5.4GHz, while power and temperatures remain well within safe limits. HWI confirms this limitation in the provided snippet. I attempted to adjust the BIOS settings to enable boost mode, but it was already enabled. Can anyone suggest a way to raise the boost frequency to around 5.7GHz on this configuration?
Yes, you can adjust the performance settings in the BIOS. Options like high-performance mode or rack mode are typically found under advanced settings and system options.
The system runs in high-performance mode, but I observed Rack mode as well—uncertain about the impact.
The maximum values appear to be around 5.7, indicating another restriction might exist. It’s possible you’re not running on a single-core processor, which is now rare and usually makes this specification irrelevant.
It appears the maximum value is being restricted to 5.4, since in diagnostics mode the CPU cap was shown as 5.4 instead of the full 5.7.
Check if HWiNFO detects C state activity while your computer is idle on the desktop. Make sure the core C states are activated so the CPU can use the 57 multiplier under light load. Regular background processes in Windows often trigger extra cores, reducing the chance of using the 57 multiplier. Consider installing ThrottleStop 9.7.3. https://www.techpowerup.com/download/tec...ottlestop/. Execute the TS Bench - 1 Thread test. If you see multipliers above 54 during testing, share screenshots of the FIVR and TPL windows. This will clarify if the BIOS is correctly configuring Turbo Groups.
It's an HP workstation designed for professional use, not casual handling. It seems certain functions are restricted—likely to ensure optimal performance and reliability. "Z's thermal technology maintains consistent temperatures for the processor and graphics card, allowing them to operate at full capacity without slowing down." https://www.hp.com/us-en/workstations/z2-mini.html
We reduce the chip's performance beforehand so you don't experience throttling
