Issue with overvoltage temperature on 14700KF CPU with ASRock Z790 Taichi Lite motherboard?
Issue with overvoltage temperature on 14700KF CPU with ASRock Z790 Taichi Lite motherboard?
As I previously mentioned, I don’t have any concerns about the cores in my 7950X occasionally reaching +95°C, as indicated by HWMonitor. This is just typical aggressive power enhancement in the BIOS meant to get the most performance from a contemporary CPU.
Before the solution for Intel 13th and 14th Generation processors, some motherboards would increase core voltage above 1.55V, leading to physical harm and premature failure of certain CPUs. After applying the fix, the peak voltage was lowered by several hundred millivolts, though I wouldn’t be surprised if the standard maximum voltage applied to your CPU remains around 1.50V.
You’ve noticed that limiting the maximum voltage to 1.365V results in significantly lower temperatures, which isn’t unexpected. If you’re content with the reduced performance at +80°C instead of the automatic boost up to Intel’s maximum of +100°C, that’s perfectly acceptable. After all, it’s your PC, and you can set any temperature limits you prefer to optimize performance.
Setting a CPU power cap to maintain +80°C is similar to reducing an engine’s RPM limit to protect it. The car runs cooler, uses less fuel, but you won’t reach the full power or torque possible with an unrestricted engine.
FPS in games usually depends on both CPU and GPU performance. In certain titles, the CPU might be the bottleneck, while in others the GPU could be limiting frame rates. Regardless, once a threshold is crossed—typically around +10 FPS—it’s usually just a minor inconvenience compared to the bragging value.
If your 14700KF consistently reaches +100°C across all cores during a game and the GPU is still underperforming, it suggests insufficient CPU power. Upgrading to a 14800 or 14900 model might be necessary. The issue isn’t the CPU temperature, but rather its overall strength. Newer games become increasingly demanding over time.
Similarly, if your GPU is struggling—such as with a 5070—upgrading to a 5080 or 5090 could be beneficial, though these options can become quite costly.
TLDR: Feel free to run your 14700KF at +80°C, but be aware that some games may become restricted if more CPU power is needed. It’s like limiting an engine’s speed to protect it—whatever suits your needs.
He is experiencing the high temperatures in Counter Strike 2....
The CPU isn't the main performance concern there.
The only cause for elevated temperatures in CS2 is the graphics card performing significant auto overclocking.
Please share images from your BIOS, specifically from the O/C tweaker section.
Thermal velocity is what drives the GPU to increase until the CPU reaches its thermal limit.
The thermal boost voltage will adjust voltages accordingly.
These settings are typically enabled by default, so simply stating you haven't made any changes won't resolve the issue.
You need to navigate to BIOS and check the relevant settings, then upload the images so others can verify if they notice any problems.
Is there any need to rely on heavy auto overclocking in CS2?
I haven’t turned on PBO or any overclocking settings on my 7950X + 4070 and 3800X + 3060 systems, opting instead for stability. The RAM on my 7950X (purchased in 2022) is capped at 4,800MT/s since it lacks a higher XMP configuration.
Many CPU cores in both AMD models consistently reach the +95°C mark during extended video transcoding sessions, as shown by HWMonitor. I treat computers as tools and avoid unnecessary strain beyond what’s required.
Topaz Video AI tends to push the CPU, GPU card, and iGPU to their limits, often resulting in a large number of cores operating in the mid to high eighties. Likewise, the 3060 and 4070 can hit their respective power limits of 170W and 200W. The room tends to heat up noticeably after a few hours of use.
While I own several older Intel systems, I don’t have 13th or 14th generation models. It’s worth mentioning that some manufacturers enable boost by default on Intel CPUs, and I remember my latest AMD systems typically have PBO disabled out of the box.
Hope the person in question can meet their goal of running cooler without overly restricting performance through artificial limits, following your advice.
Certainly, but when the mobile auto overclocks it, it does so for all applications, not just when loading something light. This issue also occurs on AMD systems, as seen in searches for "exploding AMD cpus," where the problem stems from manufacturers applying excessive voltage to the CPU.
Monitor your Package Power with HardwareInfo64. Use "Sensors Only". The CPU temperature equals the package temperature, which is the hottest core influenced by power usage (watts). Package Power depends on three main factors:
Environment (Ambient Temperature)
Software (Workload Type)
Hardware (BIOS Settings & Cooling)
In HWiNFO64, right-clicking any parameter reveals a graph, offering the best way to see real-time performance changes. The four most informative parameters are:
VID
VCore
Package Power
Package Temperature.
Package Temperature changes in direct proportion to Package Power.
Power, measured in watts, is set by the workload selected, whereas Vcore and frequency are adjusted via BIOS.
Once you've invested in premium hardware, most users want to avoid performance drops due to unintended throttling. You still have significant thermal capacity left to boost CPU efficiency safely.
Try the second lowest LLC setting, which reduces VID and subsequently lowers the required Vcore. A Vcore below 1.4 is acceptable. Raise PL1 and PL2 limits to 280 watts—slightly above Intel’s standard of 253 watts. Your 360mm AIO should comfortably support this, and increasing PL1 & PL2 will help prevent power throttling during intense CPU workloads.
You might discover room to raise your default clock speeds by at least 100 MHz.
Additionally, adding a "Contact Frame" can expand your power and thermal margins.
To OP. Have you attempted to clear the CMOS? Was this performed following a bios update? If not, begin there so we can eliminate that possibility.
I attempted to disable TVB, tried various LLC settings, but the voltage remains the main problem. I’m unsure how MSI, ASUS, or Gigabyte BIOS have addressed overvoltage issues for the 14th generation, as AsRock seems to have handled it without changes. This issue persists on the AsRock Steel Legend board too.
I faced a comparable issue before. Back then, my MSI Z790A Wi-Fi board was quite exposed. It happened a few years ago amidst the Intel discussions. I connected it with an i5-14600K and asked about the cooler type in my first update. I selected the standard model, which kept temperatures low. It performed well enough, so I didn’t encounter extreme heat early on. After a BIOS update, the settings shifted significantly. To restore optimal performance, I had to undervolt and switch the Mobo to performance mode. This consistently resolved the overheating issue. I never let it reach 100°F, and I would shut it down if it approached that temperature. Here’s the approach I used: https://forums. post#50 edit - current temperatures now stay in the mid 80sF at maximum load. I’m using the Thermalright PS120SE cooler.
