"The System has experienced boot issues because of overclocking or changes of voltages" message after overclocking.

[ronyjin123]

My CPU overclock was running fairly stable before I got a message that said "the system has experienced boot issues because of overclocking or changes of voltages" in the BIOS. It also automatically reset my multiplier back to stock. Please help!

Your overclock was not stable enough and your mobo has set the stock values to protect your PC.

If you had stored the OC values you can retrieve them and adjust them to be more stable.

I overclocked it about 2 days ago, then today it was the first time it happened. Any idea what item in the BIOS could have caused this? Many people told me I should up the vcore and update my BIOS. However, on gigabytes website it said flashing my bios could damage my motherboard. In your experience, is flashing the BIOS safe?

It's cutomary to post full specs when asking for advice.

If you're not experienced with overclocking and have not researched enough don't do it. You have to stress test for hours and depending on how much you overclock, tweak other settings too,

In your experience, is flashing the BIOS safe?

It's safe if nothing accidental happens. Power outage/bad OC/... can brick the board while it's updating.

Do you know any guides for overclocking i7 2600k with a gigabyte P67 motherboard?

That motherboard doesn't have a good heatsink. Fewer VRMs too. Ensure adequate airflow before overclocking. http://www.tomshardware.com/forum/265056-29-2600k-2500k-overclocking-guide (2600K guide)

I have a liquid cool heatsink. Also, is it necessary to wipe and reinstall Windows? That guide also says to have BIOS at latest version. I tried updating it but it didn't detect my FAT32 USB with a message "no drive detected". I am very confused. would you consider it a good idea to overclock it then?

I have a liquid cool heatsink.

Do you have them on VRMs? (6 black cubes around CPU) If not, make sure your case has good airflow for better overclock. People using water coolers usually forget about the motherboard itself.

Also, is it necessary to wipe and reinstall Windows?

it's recommended for extreme OC or after running unstable OC for months. I don't think you need it.

would you consider it a good idea to overclock it then?

Depends why you want to do it.

If you really need it, 4.0GHz should be a good start. Start there and go up if you want.
1. 4.0GHz on all cores
2. Power saving disabled from BIOS.
3. LLC (Load Line Calibration/VDroop offset) enabled.
4. Test with Prime95 v26.6 or RealBench.
5. If overclock fails, manually increase voltage. It's a good idea to save it to a profile in case the motherboard resets it.

Keep temps below 80c for daily usage.

The main reason I want to overclock is to increase fps and make sure my CPU won't bottleneck my GPU (just ordered a 1060 6gb). I am running the 2600k at 4.3 GHz right now. Mixed on whether or not I should enable or disable LLC. When disabled it gets to about 71-73c in prime95 small fft after 1 hour, however, when enabled it gets to 75c + in about 5 min. Currently it is disabled. Some people like it disabled, some people like it enabled. At this point I don't know what to do. Also, in HWmonitor it says my cpu vcore is 1.068v while I set it to 1.344 V in BIOS, any idea why this is happening?

It's not about you liking it, it's about the PC. LLC is needed for high OC. Stress test with RealBench for stability. Prime95 is better at determining max thermals.

When disabled it gets to about 71-73c in prime95 small fft after 1 hour, however, when enabled it gets to 75c + in about 5 min.

It's fine till 75c for daily usage. 85c for stress testing.

Also, in HWmonitor it says my cpu vcore is 1.068v while I set it to 1.344 V in BIOS,

Could be fluctuating based on the load. Double check with CPU-Z while stress testing. If they match, it's probably something like Cool'n'Quiet interfering.

If I were you, I would enable LLC > test stability > If it passes > under volt > test again

 

[ronyjin123]

You said that LLC is needed for high overclock. My i7 2600k is at 4.3 GHz with 1.344v, do you think it is necessary to enable? I also heard that in prime95 small fft I should keep it under 80 to be safe. Also, why would CPU-z and hwmonitor display different voltages? In hwmonitor it says the minimum vcore and the maximum vcore are both 1.068v. I am also confused when you said cool'n'quiet because I thought that was AMD software and I have an intel cpu.

If it's stable, don't use it. If not, use it. LLC is just a fancy name for voltage offset based on the load. No idea why you're against it.

I also heard that in prime95 small fft I should keep it under 80 to be safe.

Some recommend 80c, I like 85c, others have said 90c for stress testing. But we all agree below 80c is best for daily usage.

Also, why would CPU-z and hwmonitor display different voltages? In hwmonitor it says the minimum vcore and the maximum vcore are both 1.068v.

On my computer, CPUID HWMonitor has bad naming sense. VID is the equivalent of VCore. Might be the same on yours too.

Also, some monitoring softwares have compatibility issues. For example, you usually need AMD software for AMD CPU.

I am also confused when you said cool'n'quiet because I thought that was AMD software and I have an intel cpu.

I meant it as an example. We have too many names for power saving. EPU for Asus for example. You probably won't need to disable it. Just keep in mind. Sometimes overclock fails no matter the voltage we set. In the end, it's usually the power savings fault. At least for AMD. Intel usually behaves nicely.

The best advice any overclocker can and will give you is: Test and Adjust based on the results.

 

[ronyjin123]

I only wan't to disable it because it raised my temperatures. Also, in hwmonitor it has VID and Vcore, both at different voltages. I am confused because you said that VID is the equivalent of Vcore. VID is at 1.391V while running prime 95 small fft while vcore is at 1.068v.

 

[zebarjadi.raouf]

It's like this on mine.

It's like this on mine.

Thanks for the help! I think i'm going to buy a new PSU because my current one is quite bad (Coolmax CU-600B). I'll see if that changes anything, I need a new one anyways.
