Suggerimenti per Questioni7 9700k
Hello everyone, I’m seeking assistance regarding my setup. The CPU on the motherboard is set to automatic, and I notice that with cpu z the idle processor maintains around 4.7 to 4.8 GHz, which is fine under perfect voltage conditions. However, when I switch it to full load, it caps at a maximum of 4.6 GHz. I’d like it to reach up to 4.9 GHz during full load. It seems I need to adjust something in the BIOS so that the CPU turbo boost operates at 4.9 GHz under full load. I have the high performance energy configuration enabled in Windows.
My motherboard model is ASUS Z390E. Currently, I’ve set the following options (others are automatic):
XPM II
ASUS MultiCore Enhancement Disable
CPU Current Capability 140% (maximum)
Long Duration Package Power Limit 4096
Package Power Time Window 127
Short Duration Package Power Limit 4096
CPU Core/Cache Current Limit Max 255.75
CPU VCCIO Voltage 0.950 (standard)
CPU System Agent Voltage 1.050 (standard)
I’m uncertain whether disabling the energy options in the BIOS is necessary, and I’m unsure about how it should handle Intel speedsteps, Speed Shift Technology, or TVB voltage optimizations.
Thank you for your help.
By default, the 9700K is assured to reach 4.9ghz on one core only, and 4.6 on all eight:

Setting it to 4.9ghz across all cores needs manual adjustment of the turbo clock in BIOS – keep an eye on the temperatures!
Thanks! You're correct. To have all 8 cores running at 4.9GHz, you need to synchronize them to that frequency.
If your CPU cooler supports it, a full-core turbo on a 9700k can generate up to 200w. Most budget coolers, such as the Hyper212, are only rated for around 140w, which is why they enable the CPU to downclock in turbo modes—this helps control heat production. Turbo mode is a factory overclock setting, and its wattage is based on base clocks rather than turbo levels, so increasing all core turbo isn't really overclocking but adjusting the overclock parameters.
The H80i v2 has a cooling power around 220w. The I7-9700k can reach a locked core OC of 4.9GHz and output up to 200w. This means gaming temperatures will stay acceptable, though stress tests like Prime95 or AIDA64 under full load will likely cause temperatures to rise significantly, becoming quite warm or even too high for comfort. The H80i offers the best performance among 120mm coolers, nearly matching the H100i, but around 180w it starts showing its limitations due to insufficient capacity.
