Inquiry regarding 7700k Clock Speed/Voltage specifications.
So after several tests with adjustments to speed and voltage, I reached a stable result of 4.8GHz at 1.2v. The CPU-Z data confirms the voltage stayed steady at 1.229v during the full load stress test at 4.8GHz. It’s unusual to achieve such high speeds with low voltage, which is why I considered it a lucky outcome. Then I tried 5GHz, expecting it to be much easier given the previous success, and after testing various voltages (1.26v, 1.27v, 1.28v), the highest setting reached around 1.306v in CPU-Z. Each voltage level lasted about five minutes before causing a BSOD during the stress test at 5GHz. I’m curious why this isn’t possible with similarly low voltages. The temperatures during full load peaked between 68°C and 70°C, while they usually stay around 55°C to 60°C, using the EVGA CLC 280 Liquid AIO cooler for the CPU. Appreciate your time and assistance ahead.
Other users share their overclocking results and statistics.
1.306 remains insufficient; higher voltage is usually required for 5GHZ. It's straightforward to reach 5GHZ with Kabylake, so gradually increase the voltage until stability is achieved. Monitor temperature closely—80-90°C is acceptable for stress tests, but keep it below 80°C for regular use. XTU isn't ideal for stress testing; consider downloading Intel Burn Test.

What is your motherboard?
Here are some overclocking details shared by other users.
A statistics page for Kabylake overclocking is available online.
The voltage at 1.306 remains insufficient for reliable 5GHz performance; higher voltages are typically required. It’s straightforward to reach 5GHz with Kabylake, so gradually increase the voltage until stability is confirmed—monitor temperature closely (around 80-90°C for stress tests, but keep below 80°C for regular use). The XTU board isn’t ideal for stress testing; it’s better to use Intel Burn Test instead.
What kind of motherboard are you using?
I increased my voltage to 1.3V in the BIOS at 5GHz and completed an hour-long stress test in XTU, alongside testing my GPU overclock. The results appear stable. CPU-Z shows a maximum voltage of 1.325V under those conditions, which seems acceptable. I’m wondering if I’m truly capable of achieving 5GHz with such low voltage. I’ve also tried Prime95 and LinX, but they affect voltage levels and cause the CPU temperature to rise above 85°C, which isn’t ideal. During the hour-long test, my maximum temperature stayed around 77°C, mostly between 55°C and 70°C. I’ll consider using Intel Burn Test again, though this overclock seems stable based on my previous attempts.

My motherboard is a MSI Z270 Gaming M7
Start with manual voltage at the early OC stage. It seems you're using offset, but XTU won't assist in achieving a stable OC for your system. Even the best stress test tools like Intel Burn Test can't do this, but IBT is the only one I've used that pushes the CPU heavily. Also, avoid exceeding 90°C during IBT—temperatures in games are usually higher, so for regular use you shouldn't go above 80°C. If your vcore during the stress test is higher or lower than what's set in BIOS, adjust the LLC setting (it should be shown as a percentage in MSI).

Don't exceed 90°C during IBT; it's safe to stay within that range. For regular use, keep it below 80°C.
If your vcore during IBT stress test is higher or lower than what you set in BIOS, adjust the LLC setting (it should show as a percentage in MSI).
I'm manually adjusting the voltage in BIOS and it's in adaptive mode. If that matches your idea. I know no stress test can truly confirm system stability, so I prefer using the system normally and checking for issues if they arise. Stress tests also affect me personally, not just the CPU—I sit there watching the temps for hours because I'm worried about overheating.
Also, could you clarify what you mean by LLC?
This refers to static voltage that stays constant during idle or under load, maintaining a consistent level throughout.
Stop overclocking the CPU first and then proceed with GPU adjustments.
LLC helps avoid voltage drop when under heavy demand. If your VCORE reading in HWmonitor differs from what you set in Bios, you should tweak LLC or consider it ineffective.
Use IBT for 10-15 minutes—don’t run it for hours like many do—stability is key. Playing games such as ROTR or Crysis 3 works best for me. You can also run IBT simultaneously.

Makentox explains the concept of static voltage, emphasizing its consistency during idle or load conditions. It suggests skipping CPU overclocking before addressing GPU adjustments. The guide recommends using IBT for short durations without prolonged use, noting that playing games like ROTR or Crysis 3 provides optimal results. It also mentions running IBT alongside other tasks and shares a link to an overclocking resource. The text addresses concerns about CPU-Z readings not matching BIOS settings, advising LLC adjustments if needed. A caution is given regarding the risks of running Intel burn tests, highlighting potential damage. Finally, it asks about the benefits of delidding and requests advice on necessary materials and procedures.
