hello everyone my spec
cpu: i9-10900k
mobo-asus rog maximus xii hero z490
memory- g skil 2x16 3600mhz
gpu asus stirx rtx 3080 ti

my cpu is on 5.1 ghz 1.27 vcore with llc7 for 6 month

recently after the cinebench end with score my pc freezes and i need to restart manualy

Does it crash without any over clocking/voltage?

That does not answer the question.

Your load-line calibration setting is too aggressive and the voltage drop crashes the processor. Your processor also may have degraded from running at such a balls to the wall setting for so long, and may no longer be capable of holding 5.1 GHz. You might want to redo your overclock targeting around 4.9 with less aggressive voltages.

1.27 is aggressive voltages?

If it only were that simple. You have load-line calibration enabled and at a very high setting, from the symptoms you describe your processor is crashing during the transition period from high load to low load because of overshoot. Cinebench shows this by freezing the whole thing, Prime95 would throw rounding errors a plenty, etc.

Then you factor in any AVX offsets further messing with voltages, etc. - it's just not worth it pushing your machine so far, the benefits in real-world workloads are very limited in comparison, besides, your processor is not new. The 10th gen CPUs are "obsolete" if you're after high benchmark scores, pushing it not only isn't going to change that, but it's unwise related to how much work you will have to put in to get it stable in the long term and also for the reliability and longevity of the hardware. Everything that your CPU can do at 5.1, it will do at 4.8-4.9 without crashing and without throwing more volts at it than you'd ideally like to.

If you don't care about it, by all means, go ham :oops:

Is the voltage eactly 1.270? try both 1.275 and 1.280 if it passed then it could be deg or could just be related to change in weather/season from 6 months ago.

I would also try lowering to 1.265 and see if that makes things worse or not.

In TPU review they neede 1.33V for 5.1Ghz OC

CPU has been running for months with a high LLC setting, its fair to assume that it has been degraded to some extent, unless exceptional cooling has been used and the processor kept at a very low temperature. Lowering the voltage will not help, increasing it will mitigate until the CPU gets further damaged - it's a snowball. The wisest course of action is to simply dial back the clocks and voltage a little bit, and enjoy the processor for what it is. You're not going to have a massive general performance or game frame rate loss by shaving 200-300 MHz out of that processor, in fact, I doubt you'd be able to tell most of the time, yet it will be much nicer to the silicon, closer to the spec and significantly easier to stabilize.

Let's be frank: Frequencies in excess of 5 GHz are simply not needed on a Comet Lake processor, even if I understand it's a point of pride for certain Core i9 users. Well I got news for you: running those giga high frequencies isn't gonna make your processor better than a Ryzen at multithreaded benchmarks. Voltage is not everything, LLC violates the specification for load-line and increases transient current, which is what causes electromigration to begin with. The mechanics behind it are known as Black's equation, and in essence, the longer the processor is exposed to a high current at warmer temperatures, the quicker it will deteriorate. Vdrop mechanics are intended precisely to counter that as load (and current strain) increases, LLC may help stabilize a processor but it should never be used at aggressive settings because it's just as violent as putting say, 1.6 volts onto the processor to begin with, if not worse.

I've done that folly to my Core i7-990X back in the day, I learned this the hard way. When it was new it would run stock at below one volt and would bench at 4.8 GHz around 1.375v. The last time I used it, it would crash at 1.2v at stock and would need 1.55v for 4.4 GHz, and it would still crash. And yes, I chucked electricity quite happily at it for many years to get to that point. I just haven't found the heart to make a keychain out of it yet, it was the only part out of my old X58 kit I haven't sold because, well, it's junked.

Your oc is unstable, back it off and run it

Succinct and to the point, I suggest OP follow our advice :toast:

Most probable cause is incorrectly configured XMP/DOCP profile.

Yup gotta know if its stable at stock settings, if its not then there is a problem with the cpu/mobo/ram, possibly PSU, or bad temperatures
