There are potential overclocking power problems, any assistance would be greatly appreciated.
There are potential overclocking power problems, any assistance would be greatly appreciated.
I want to start by noting that I’m new to overclocking. I’ve done a good deal of research, but haven’t had much hands-on experience.
Recently, I upgraded my system to the Z370 platform. It now runs a Maximus X Hero motherboard, DDR4 Corsair Dominator Platinum-3000 RAM, and an Intel i-7 8700K processor. I’ve experimented with increasing the CPU and RAM clock speeds, but whenever I turn off the machine completely and restart it, it only powers on briefly before shutting down again. After a couple of seconds, it restarts normally. I’m familiar with similar issues, and I believe they stem from over-current protection or power-related problems.
After resetting my BIOS to its default settings, the problem vanishes. I’ll share a link to my complete build and a screenshot of the voltages on my components at those settings. If this is indeed a power issue, I thought it would help.
Thanks for reading,
Nick.
Here are some alternatives to the original text:
- Remove one RAM chip and leave another in place, following the instructions in the manual that came with your motherboard.
- Launch Windows, configure XMP settings, save changes, then exit.
- After initial startup, it may restart a few times but should function normally after a standard reboot.
- If this fails, swap the RAM module into a different DIMM slot and repeat the process.
- Continue testing with one module in each slot until all four slots are verified (repeat the test with another module if needed).
- If the issue remains unresolved, try using a different RAM chip in an alternate slot until the problem is resolved.
lumineZ :
1. What are your CPU temperatures when everything is running with default settings?
2. Have you attempted to overclock only the CPU, excluding the RAM?
3. What speeds are you aiming for with the CPU and RAM?
1. Idle: 20-25°C, under load 50-55°C, up to low speeds; 60s under heavy load.
2. I agree, but I’m open to repeating the test. Should I suggest increasing the core clock multiplier or also the voltages? I’ll share a link to the video guide I was using for reference.
3. I didn’t heavily overclock my RAM; I just raised it from its stock speed of 2133 to 3000. For the CPU, during testing (which was interrupted by this issue), stable results were seen at 4.8 and even 5.0 GHz, though temperatures reached high 70s under load.

Well first of all, I can say that
der8auer
the one in your video... You can rely on him. He is a well-known overclocker who aims for world records.
Try these steps first:
- Reboot and load BIOS.
- Configure XMP for your RAM (using Extreme Tweaker ---- AI Overclock Tuner).
- Save and exit, then load into Windows.
- If everything works, reboot and reload the BIOS.
- Now adjust
Vcore to 1.350
(under Extreme Tweaker ---- CPU Core / Cache Voltage).
- Proceed to CPU Core Ratio and choose
Sync All Cores.
- Enter 1-Core Ratio Limit, input 48 (4800Mhz).
- Save and exit.
- Load into BIOS and open 2–3 programs quickly to stress the CPU, then monitor temperatures with a program.
- If the system didn’t freeze or crash, reboot back into BIOS and lower the 1-Core Ratio Limit to 49 (4900Mhz).
- Repeat this process until the system crashes or freezes. (Or stop if you reach a stable setting due to high temperatures.)
Once the system stops working, perform a hard reboot, return to BIOS, and reduce the 1-Core Ratio Limit by one tick (if it crashed at 52, set to 51) before saving and exiting.
In Windows, run a stress test such as Aida64 Extreme for 2 hours, keeping an eye on CPU temperatures.
If it completes without crashing, proceed to Vcore tuning.
Start with
1.350
and gradually decrease until the system crashes during testing. Adjust by 0.010–0.020 points depending on your CPU temps.
And that’s it. You’ve successfully overclocked the CPU.
Now there are other aspects you can experiment with when pushing the CPU further, but I won’t go into those details right now. (This process takes a long time)
For RAM overclocking, I’ll leave that to someone more experienced. (I don’t do it because I don’t see any benefits.)
And please let me know if you encounter any issues or crashes during the overclock process. At what stage did the problem begin?

If you complete the test without issues, proceed to Vcore tuning. Decrease Vcore from 1.350 to 1.340 gradually until the system crashes during testing. Adjust by 0.010–0.020 points depending on your CPU temps.
That’s it. You’ve successfully overclocked your CPU. There are still other factors you can tweak, but I won’t go into those now. (This process takes a long time)
For RAM overclocking, I’ll leave that to someone more experienced. I don’t do it myself because I don’t see any benefits.
And please let me know if you encounter any issues or crashes during the overclock process. I’ve completed all these steps. As you mentioned, setting XMP for RAM is important. If I enable it and power off the PC, it shuts down again. When I restart, it comes back after a short delay. Since I’m new to this, I know it’s not ideal and could harm the hardware. This is exactly what you need help with.
Here’s the adjusted version:
The issue with the XMP settings seems resolved. Please follow these steps:
- Remove one RAM module and leave another in place (check the manual for the correct slot).
- Restart Windows, enable XMP, save your changes, and close the program.
- After a few attempts, it should restart and boot normally.
- If it still doesn’t work, remove the module from one slot and try another.
- Continue testing all four slots until you find the faulty one.
- If one module works but not the other, run MemTest86 overnight with both installed to check for errors.
Good luck!
