bsod clock watchdog timeout

[Leoplate25]

Hi, i don't know if it's in the right category but here's the thing: I set MCE to enabled, and so the i5-9600k run at 4.6ghz (max turbo for one core). The thing is the second i run Cinebench i have this BSOD "clock watchdog timeout". If it disable MultiCore Enhancement, it runs just fine. Is it a problem of MCE (i read that it is a little bit unstable) or is it a voltage problem? If i remember correctly i get 4.6ghz at 1.156v (i think it's enough, and i know it depends on the chip). I am not planning on running my system with MCE, but i don't like my machine to have BSOD's like this one. Another thing is that i am not planning on do any OC because i am kind of a noob in the filed. Thanks!!!

EDIT: If i enable MultiCore Enhancement should i disable turbo boost and viceversa?
EDIT 2: I have an i5-9600k, ASUS Maximus Hero XI, 2x8gb Crucial Ballistix, EVGA GTX 1070 ti SC, Bitfenix Whisper M 750w, Corsair H100i v2, Samsung EVO 840 250gb, Samsung EVO 860 1tb.

Your overclock is unstable. Bump the voltage a tad.

Hi. Enabling ASUS MultiCore Enhancement is considered overclocking? If you enable MCE you should disable turbo boost?

You were right. I enabled MCE and set the voltage to 1.2v manually and i don't have BSOD's anymore. The BSOD appeared a second later i ran Cinebench. The auto voltage was at 1.165v and i set it to 1.2v and problem solved. Should i use MCE if i am not doing any OC? Or shoul i run the cpu at stock settings? Could it be that running at 4.3ghz all cores have enough voltage but not at 4.6?

MCE is basically setting all cores to max turbo. Instead, for example:
Core 1: 4ghz
Core 2: 3.9ghz
Core 3: 3.8ghz
Core 4: 3.7ghz

MCE on:
All cores: 4ghz

That requires more voltage since all cores are now at max turbo. It's the same with my 4790k, setting all cores to 4.4ghz boost. If that small voltage bump is all you needed then you're good to go.

Thanks for your answer. Yes, i know how it works. What i don't know if it uses the same voltage at 4.3 that at 4.6. I don't know if you understand me. I think the 9600k works like this: 1 core 4.6ghz, 2 cores 4.5ghz. 3-4 cores 4.4ghz and 1-2 cores 4.3ghz. If i enable MCE, the voltage should raise, isnt it? Or it keeps the 4.3ghz voltage? I think i didn't get a great chip, haha! Thanks again!

MCE may not bump voltage to counter the clock increase, hence causing your BSODs.

You solved it by setting the vcore to 1.2 instead of auto which obviosuly couldnt provide enough voltage for the boost clocks under load. 1.2v is still well within safety limits so you're good to go.

If you want to be a bit more thorough then run IBT/P95 for an extended run with your 1.2v vcore and make sure it's 100% stable throughout the benchmarking

Weird thing just happened, i set offset voltage with +0.5v and when i run Prime95 v26.6 SmallFTTs it says on CPU-Z, 1.110v and it ran just fine, but if i run on auto settings it crash when i start the stress test (half a second and it crashes), same with Cinebench. What is going on then? Because it uses less voltage but it doesn't crash!

 

[NdMk2o1o]

+0.5v offset is not recommended at all, if your auto vcore is 1.15 then adding a 0.5v offset would increase this to 1.65, so yea it won't crash cause of lack of voltage but you risk damaging the processor or reducing it's life span. Hopefully you mean 0.05, either way, I would stick with what you have found stable in 1.2v manual vcore and go from there. Also CPU-Z doesnt refresh vcore in real time like it used to at least in my case anyway, I can run 2x instances of it and stress test and both instances show completely different vcore, sometimes it doesn't refresh when it should.

Sorry i missed a 0, haha! 0.035v is the offset + voltage. Ran Cinebench 5 times without any problems. Now running Prime 95 26.6v SmallFFTs (1.120v). 64 degrees C tops at 4.6ghz with Corsair H100i v2.

Glad to hear you're not intentionally frying your proc lol but those temps and voltages seem fine, fingers crossed.

Thanks for your answers. One hour is enough of Prime95?

 

[NdMk2o1o]

Well, that's subjective, some people will say yes, others will say, 4/8/12/24 hours etc lol I guess it just depends on your frame of mind, personally I don't run stress tests too much I use my computer like I would normally do, play intensive games, web browse, multitask etc and I soon know if an OC isn't stable enough for my particular use case. I don't have the patience for 24 hours of P95, so I just use my computer like I always do, if I get a BSOD or crash, reboot etc then I'll go from there. I guess YMMV

I've had games not like CPU overclocks but synthetic benchies take it. Just do your daily usage.

Thanks guys! Let's daily usage tell me if everything is stable. I set all cores at 4.3ghz on auto settings, cinebench ran fine, prime is running fine too, 1.048v, 56 degrees C. Before this, with MCE enabled i got BSOD's (at 4.6ghz), now at 4.3ghz i'm happy with the temps and this speed. Cheers from Argentina!

 

[NdMk2o1o]

go for 4.5/4.6 turbo boost for all core, it's definitely capable of that and more

 

[biffzinker]

it's definitely capable of that and more

Might even be capable of 5 GHz as long as the heatsink cooling is up for it.

86 degrees C at 5ghz :/
