Is my 14900k ok?

[dsan]

Hello guys.

I am completely new to hardware. Four months ago, I bought a new computer that is primarily used for 3D/Rendering/Programming and occasionally gaming.

The machine is as follows:

• Intel i9 14900K
• ROG Maximus Z790 Hero
• Corsair AX1600i
• Corsair iCue H170i Elite
• 2x 32Gb DDR5 Corsair CL32 6400Mhz
• Asus RTX 4090 ROG STRIX

The BIOS installed by default is version 2202, which (I believe) already includes Intel's profiles. I have never had a single issue with the computer until yesterday when I experienced a complete system freeze (for some unknown reason).

Below, I’ve attached some photos of the results from HWInfo after running a test with Cinebench 2024. I also ran a test with the Intel Processor Diagnostic Tool without any errors.

Is it possible, with this data, to determine if my system is stable or if I might encounter problems with this configuration in the future?

Thank you.

If you have the latest BIOS you should be fine, no more degradation.

But the hardware has been in use for four months, so the chip may have degraded already despite the progressive measures Intel put to limit damage.

The temperatures and voltages look fine for a 14900K, the 14900K is notoriously difficult to cool.

If you get another unexplainable crash or bsod you may want to RMA anyway, since the CPU is in a gray zone where it may or may not have degraded enough to cause crashes/freezes.

As a general rule, if your chip saw extended, unthrottled AVX loads on few enough cores that it didn't throttle either from temperatures or power limits it has probably degraded.

I don't have the last BIOS.

I have the 2202 version, the first one that came out with the Intel profiles.

I saw alot of people having problems with the last one and trying to downgrade to the previous..

Is there any safe way to test the chip? I already tested with IPDT and Cinebench. No errors, everything ok, but the CPU reaches 100º, 350W+, 1.445v.

I'm very, very confused about this topic. Don't know what to do to be honest. Right now the system is stable but I'm not sure if it's beeing damaged with these values..

UPDATE:

I flashed the bios with the new update (0x129 microcode) and applied all the intel default settings, performance template.

All my temps, vcores, watts are now ok. No errors, no throttling and same performance!

Thanks

I received a 14900k in rma from my 13900k. I start, go to the bios (bios 0x-129), I start under windows (10x to be honest), blue screen, black screen, impossible to launch a game because return to the windows desktop. Drivers up to date, Windows 11 reinstalled, my cpu when I can test it is below the 13900k! I tested memory by memory, computer restarted, black screen, blue screen, unstable (voltage of 1.44v however and temperature at 44 degrees at rest). I'm stuck there...

Hey @ToUsMiC .

I'm not an hardware expert to be honest, but I can try to help you.

In the bios settings, did you applied the Intel Default settings? If yes, which preset? Performance or Extreme?

That 1.44v voltages is under heavy load or idle?

I just put my RAM by default without XMP, the computer starts, I arrive on Windows, nickel. I launch a game, it starts then cuts. I launch another game, it starts then cuts. I launch cinebench, it starts, I press multicore test, the test cuts. I arrive. launch cpu bench and intel extrem bench, point = 4780 I restart cinebench, miracle it starts in multicore test, I do 1 pass, result I am below an i7 7700k !!!! I restart cinebench, 2,3 passes then blue screen. I reinstalled Windows (tried because blue screen during installation). A friend arrives, I test his 12900k and a 13900k, no worries. 40 years of computing and now I'm completely stuck. I don't know what to do and I've been building PCs for 40 years. I RMA'd the 14900k and asked for a replacement with a 12900KS. We'll see. To be continued... the profiles tested are those of Intel (performance or extreme), the vcore displayed when I launch a test (it crashes after a few seconds) does not exceed 1.48v. I really don't understand

J’ai peut-être trouvé le problème. Ma RAM ! Ce que je ne comprends pas, c’est qu’il fonctionnait parfaitement avec mon 13900k en XMP1/2 sans jamais avoir de problème. Voici ma RAM : F5-6800J3445G16GX2-TZ5RK
Trident Z5 RGB
DDR5-6800 CL34-45-45-108 1.40V
32GB (2x16GB)
Intel XMP. Il est configuré au minimum JEDEC 1 mais ça me dérange de travailler à 3600mhz quand il fait 6800mhz (en oc je sais ça)

J’ai 64GB (4x16) avec Asus Strix z790-a DDR5 Wifi (pas Wifi II)
