BSOD when overclocking in intel xtu high temperature please help blue screen crash

[sk3510]

Hi,
I have a 8700k on a z370 carbon pro ac motherboard. I opened intel xtu and set each core multiplier from 47 to 50. So my cores were all running at 5.00 Ghz. I did not mess with the voltage. I ran xtu stress test for 5 min. Everything was stable and the max temp was 80. I have a corsair h115i.

Then I ran a xtu benchmark and immeditaely I got a BSOD and computer restarted. I am really worried if I damage my CPU or motherboard or any other component. I am new to overclocking.
Please help with the questions
Why did I get a BSOD
Did I damage anything in my Pc by getting a bsod.

Thank you for your answers. Really appreciate it

5Ghz is an unreasonable expectation for a full time overclock unless you are willing to either delid it yourself or send it out to a service which will perform the delidding for you.

4.8Ghz is a much more reasonable expectation but even then you MUST increase the voltage or it will NEVER be stable even in the short term tests much less in any long term stability testing which NEEDS to be done if you don't want micro errors and silent data corruption to occur.

Realistically there's not that much to gain for the average user from overclocking the 8700k. It is a fantastic CPU that ALREADY boosts to 4.7Ghz all on it's own in the stock configuration, so there's really not a lot to be gained by it unless you are a seasoned overclocker who already knows what to tune and what to expect from the OC. Plus there's the fact that with the amount of voltage necessary to drop a full time 5Ghz OC on any Gen of CPU is likely to greatly diminish the life expectancy of your CPU and probably your motherboard voltage regulation components as well.

Cooling is a whole other issue. If you don't have top notch cooling in the upper 10-20% of what's out there, you're unlikely to keep that thing cool enough to comply with the thermal conditions that must be met in order to avoid serious damage very quickly. What CPU cooler are you running and what is the reason you are trying to overclock this excellent processor?

I wouldn't say an H115i is that great of a cooler.

Liquid cooling doesn't mean it's good liquid cooling.

I would have thought it best to overclock from the Bios..Also at 5GHz, vcore and LLC will pobabaly come into play unless you got a super golden chip...

BIOS overclocking is always the best route to go.

I am using a corsair h115i cooler. I just increased the core multiplier to 50 while the refrence clock was at 100mhz. So during intel xtu benchmark the temperature was ~80 but the pc crashed into bsod. It restarted and everything works fine. I know not a huge gain in ocing. I just was curious to know if i have a good chip. So i oced without changing the voltage. So the bsod which happened do you think it caused any damage to any part of my pc? thanks a lot for taking your time to reply. really appreciate it

Damage? Not likely as it would probably be noticeable by now. Is it possible? Yes, you can really get some things wrong and mess up motherboard controllers and memory if not set correctly. Dead CPUs are also possible under the right (wrong?) circumstances. Increasing clock speed typically means you need additional voltage to sustain higher clock speeds per cycle.

To me, a good chip is one that can give me an 800mhz-1Ghz overclock which is STABLE and stays within thermal spec AND lasts me five years or more. At 4.7Ghz that is exactly what your chip would be doing with a full time 4.7Ghz base clock setting. Anything beyond that is merely for testing, for use on a system that you don't really care about if it fails or for people who upgrade every cycle or two and don't need it to or care if it does last much beyond two years.

At least, that's how I see it. So I'd say if you can get it stable and keep it below 80°C during Prime95 version 26.6 stress testing for 24 hours, then there's not much more you could, or should, ask for. That would be the measure of a good CPU for the everyman.
