About Cpu instability on 14400f

[Marcos7]

Can the 14400f have instability issues too or Just the unlocked cpus?
I noticed some strange fram drops while gaming ,idk It its normal or can happen with more basic 14 gen cpus.

[n_scott_pearson]

All desktop CPUs could exhibit the problem.

[Marcos7]

So ,How is better way to check If i have faulty unity?

[CoolBook]

No, it would be highly unlikely for your CPU to be affected by the overvolting issue.

There are some claims that all (65W and up) CPUs could be affected, but I doubt there are actual examples of that.

Perhaps your GPU is too slow? Not enough RAM? Or perhaps that CPU is not powerful enough?

Instability would not cause dropped frames.

The application might quit unexpectedly or you get BSOD and/or hard reboots.

There would probably be a higher risk of defects with most other components than that CPU.

That because of the low frequencies and voltages it uses.

As always, just make sure that your CPU has healthy temperatures and voltages.

try Prime95 small FFTs stress test, if that fail, then it must be the processor failure

[Marcos7]

One hour is ok to let test runing?

[aCNuser]

yes,if there is no error in 1 hr, the cpu should be ok, then you can try  large ffts,its to test ram, if both is fine and no error,i think it will be less likely to be the cpu and ram

and out of my curiousity could you provide a CPU-Z screenshot? I heard that 14400f should have two kinds, and it may could be identify by steeping in CPU-Z, for B0, that is new cores of 13/14th gen, it should have 2mb L2 cache per Pcore on the chip, and been cut to 1.25mb per Pcore, for C0, it is like 12th gen die and have 1.25mb L2 cache per Pcore natively.

if your cpu is B0 steeping, i think it may （only my personal speculate）related to recent "instability issue"

Morning, i Will send the prints of cpuz, yesterday i got delta force hawnk ops freeze and crash to desktop, but not Just me some people complaning about crashes too,  the game is in Alpha state, so after that i play for 4 hours Max settings avainable in game with no issues 144fps my screen is ultragear 144hz, o Will make another prime test today to ,check when testing prime with How monitor opened CPU Max tempo reachd 56°c and 1.245v  but o noticed some times P cores drop frequency to 3.296 but CPU never exeed 65w

[CoolBook]

Looks like your CPU is limited to 65W, so the MT Prime test might not stress the cores that much.

Voltage seems a bit high if that was for 3.3GHz though?

[Marcos7]

I guest i Will sent It back to Intel ,for warranty ,its too much work for a entry level CPU so o dont want spend time in that, Thanks for the help !

[CoolBook]

Personally I think replacing the CPU and finding out that you still have the same issue would be way too much work.

How do you know it is the CPU?

[Marcos7]

My Full Spec 

[aCNuser]

it is C0 so your cpu seems using 12th gen CPU die, and 14400f don't have a super high clock speed,so i think it is less likely to be affected

for your reference, i am using 13900k and i have already applied the RMA, even i have already down it to5.0ghz, it still blue screen or just frozen in 1 sec if i start running prime 95 small ffts

i think if there is no problem running that test it should be very safe to use, this test have much more heavier stress than almost any other test

[Marcos7]

I have never had a blue screen since I bought the 14400f, but two days ago I went to play Delta Force Alpha and the game frozed and closed, only once after I installed it, after i spent the whole day playing and had no problems, the other day I also had no problems playing all day, Diablo 4 too, when I was walking around the map the game froze and closed by itself, but only the first time after installing it. But it could be something related to the DX12 cache (fresh installed Windows, without DX12 cache) because both games only had this happen the first time I opened them they ran normally and had no more problems, just a few frame drops but it is normal because in Delta Force there are 64 players and there are a lot of explosions and in Diablo there are a lot of enemies on the screen.

[Marcos7]

How do you know they used 12 gen die?

[aCNuser]

it is C0 revision so it is 12th gen die, if it is B0 then it is 13/14th gen die.

it is chinese language video, tells the difference about b0 and c0

[aCNuser]

when running Prime 95, you can see the taskmanager to see if there is a core have no load for over a minute, and there is a error info in a thread of P95, then it means that in this core it reports error, you could try manually down the frequency and it will help

[CoolBook]

@aCNuser 

Do you mean a single tread Prime 95 test? Otherwise you might not see those ST boost frequencies and voltages.

[aCNuser]

emmm, i do found the failure core using this method, and i am doing it with all thread simutanously, if you want to try it with single thread, you may need to manually set the core software running in taskmanager i guess
