Beginner. I7 8700k. 4.7ghz all core, everything else on auto. Is that correct?
Beginner. I7 8700k. 4.7ghz all core, everything else on auto. Is that correct?
I recently assembled my very first computer.
I used:
-ASUS ROG Strix Z390-e
-I7 8700k
-32gb TridentZ RGB 3200mhz RAM
-Coolermaster MA620P dual tower with massive dual fans
-850watt 80+gold Thermaltake PSU
-ASUS GTX 1060 6gb
-Phanteks Enthoo Pro case
-2x 250gb Samsung 970 EVO M.2 SSD in RAID 0 for boot drive
-1x 500gb 850EV0 SSD
-1x 6TB Toshiba HDD
And my actions were:
- Activated XMP_II
- Configured all cores to sync automatically
- Set multiplier to 47
I left the rest at auto settings since I’m still learning and want a stable build.
My concerns are:
Are these configurations safe?
Particularly about keeping the voltage in auto mode.
Could auto-voltage provide more power than required, and is that acceptable?
What tests should I perform to verify safety?
During regular operation I haven’t noticed any CPU core temperatures exceeding 63°C.
I’m unsure what else to check.
Or does this seem like a straightforward setup without much risk because I only reached 4.7GHz and temperatures stayed normal?
Please let me know.
I’m new to this and just wanted to be cautious.
the xmp profile is adjusting your vccio for the ram to run at 3200mhz. vccio isn't generally something you need to worry about or manually adjust, or if anything, lower it if you really want to until you are unstable. your vccio is fine, software voltage monitoring isn't perfect, im sure in reality it is running at 1.30v. if you are not having stablity issues or any excessive heat from i wouldn't worry about it.
just checked my hwinfo64, my [email protected] delided with 16gb@3200mhz@cas16 shows a vccio of exactly 1.344v. it has been running fine for over a year now.
Technically that is an overclock since your putting all cores to 4.7ghz. It's fine however. I'd recommend setting the multiplier to auto, so your using stock voltage and the motherboard doesn't put too much voltage into the CPU for no reason.
Then, stress test with ROG RealBench for about 8-10 hours to insure that all cores can run at 4.7ghz fine.
I recently assembled my first personal computer.
I have the following components:
- ASUS ROG Strix Z390-e
- Intel i7 8700k processor
- 32GB Trident Z RGB 3200MHz RAM
- Coolermaster MA620P dual tower with massive dual fans
- 850-watt 80+Gold Thermaltake power supply
- ASUS GTX 1060 graphics card with 6GB
- Phanteks Enthoo Pro case
- Two 250GB Samsung 970 EVO M.2 SSDs in RAID 0 for the boot drive
- One 500GB 850EV0 SSD
- One 6TB Toshiba HDD
My approach was:
- Activated XMP_II profile
- Configured all cores to sync together
- Set the multiplier to 47
- Left other settings at their defaults since I’m still learning and want a stable build.
My questions remain:
Are these configurations safe?
Particularly with the auto voltage setting.
Could auto-voltage provide more voltage than necessary, and is that acceptable?
What tests should I perform to verify safety?
During regular operation I haven’t noticed any core temperatures exceeding 63°C.
I haven’t examined anything else.
What aspects should I focus on?
Or is this just a straightforward setup because I only reached 4.7GHz and temperatures stayed normal?
Please don’t think these are silly. This is my first attempt at overclocking.
No. Overclocking with auto voltage is never advisable. Greater control means better results.
Once you apply a 47x multiplier for 4.7GHz, you must manually adjust the voltage. I never suggest exceeding 1.35 for reliability. These chips can safely reach up to 1.45.
After setting the voltage and multiplier, turn off Multi-Core Enhancement.
Disable CPU SVID support (found in BIOS) and Intel’s Speedstep feature.
Post-setup, run a stress test to confirm stability under load and ensure adequate cooling.
I rely on CPU-Z and HWInfo for temperature monitoring.
Ideally, keep temperatures below 85°C and ideally under 90°C.
I usually aim to stay under 80°C, at my discretion.
If temperatures remain consistently high but the system runs without issues, lower the voltage until it meets your thermal goals.
If crashes occur during stress tests after lowering the voltage, reduce clock speeds accordingly. Adjust these values gradually until stability and temperature targets are achieved.
You can stress-test with Prime95 using SMALL FFT; ensure you use version 26.6 as newer versions use AVX instructions that may exceed manual settings and risk damage.
The auto configurations on the ASUS boards are quite acceptable, particularly at the low 4.7GHz setting combined with XMP. As Andy11466 mentioned, perform a brief test using Prime95 version 26.6 with the 'blend test' to observe your temperatures during peak load. The small FFT analysis is not typical and should only be used by serious overclockers since it won’t stress your system at this frequency. Running Hardware Info simultaneously will display live temperatures and the voltage, while CPU-Z offers a more user-friendly view of the VCore. This information can be a bit complex for beginners.
Thanks for the assistance. I'll review these settings tomorrow after work. I'm currently running hw monitor and have observed that with auto mode, my maximum voltages are 1.315 and the highest temperature on any single core is 63°C. Although I haven't performed a stress test, I attempted to run multiple tasks at once beyond normal limits. Thanks again for the advice; I'll check these settings as soon as possible.
These are the voltages I recorded after using my computer for a few days as usual. As mentioned before, I only adjusted 2-3 things in the BIOS. I turned on “sync all cores”, activated the XMP2 profile, and probably chose no for the prompt that appears afterward, though I’m not sure. I set the multiplier to 47 and left everything else auto. I haven’t had a chance to revisit and modify any of those settings, so they remain unchanged. Here’s a picture of hwmonitor. I observed that my VCC voltage seems higher than what others recommend it can handle—around 1.328V and 1.344V max. But I’m not sure why that is. I just need some guidance on what to adjust. I’m running an ASUS Strix Z390 with an 8700K processor. If anyone familiar with this BIOS can help, I’d really appreciate it. A simple explanation would be great, along with links to forums with clear instructions. Please refer to the post above for a list of all components. And let me know if these settings are acceptable or if I should keep running as is.

I noticed my VCC voltage seems higher than what others recommend can be sustained. It reads 1.328min and 1.344 max. But I’m not sure why that is. I just need some guidance on what to adjust. I’m using an ASUS Strix Z390 with an 8700kHz clock. If anyone knows more about this BIOS, any advice would be greatly appreciated. I’d also love links to forums with clear explanations.
Please refer to the post above for a list of all components. And let me know if these settings are acceptable or if you should keep them as they are. You’re on the right track—your VCore is not too high at 1.305V, which could be lowered to 1.26V or 1.27V at 4.7GHz with some adjustments. That would require learning how to overclock manually.
You’re doing well—your VCore is stable at 1.305V, and temperatures are safe. Just staying within the safe range means no problems right now. I suggest using a Gigabyte Z370 gaming motherboard, so your BIOS is different, but you can look up settings online to start your overclocking process.
Thank you for the assistance...
Apologies, I shared the photo upside down.
It was taken straight from my phone.
I just used the snip tool and reposted it.
Thanks again.
