New bios 2202 Z790-F Gaming Wifi

[emred]

Notes : "The update introduces the Intel Baseline Profile option, allowing users to revert to Intel factory default settings for basic functionality, lower power limits, and improving stability in certain games.

No, I ran them when I had instabilities started occurring, never ran Prime95 on the system prior, the most I ever ran before was Cinebench 23 and 15 a couple of times, that's it.
The rest was gaming and everyday use.
I only ran 6400Mhz DDR5 ram too, so nothing overly stressful.

First time I noticed something odd was when I couldn't install the nvidia driver, no matter what card I had in my system, swapped out for a 14600k left it at auto, drivers installed, swapped back to the 13900k left auto, they'd fail to detect the gpu, but if I lowed my E-Cores to 3.5Ghz, system was fine.
It wasn't even the P-Cores that failed.

I wouldn’t run it all. Especially small FFT.

Regardless, looking at the number of cases available, the majority of users experiencing issues are normally right off the bat rather than after prolonged use. Generally throughout my experience sticking within 2x the stock TDP is a reasonable rule of thumb.

Probably why mine took so long to degrade, I wasn't hammering my system, I made sure it never went over 90c.
But yes the power limits were insane, my old 13900k had a SP of 99, the replacement is 97, both will downclock running any heavy loads and would easily draw 330w to maintain 5,5Ghz on the P-Cores to stop downclocking, I never let it run that high though.

Limiting the power input is fine for gaming, temps are better, happy doing 5.5Ghz, see this is the thing I never had instabilities while gaming either, just anything that used the E-Cores in Windows was unstable.

I doubt it actually degraded much at all. People throw this word out a lot without really substantiating anything. Anything that pulls more than the specification current can accelerate the process of electromigration, just not noticeably within a CPU's usable lifespan.

I don't tend to run high current workloads for hours on end to test stability. Throughout my tenure on the forum most people that do this are the ones that end up noticing these things. However, several generations ago when Intel throttled AVX instruction made it quite difficult to push high amounts of current through the die.

I wouldn't conflate having a base profile for stability with having one to protect the CPU.

I was sent a series of tests from Intel, one was running at defaults, no XMP etc.
The instability was within the E-Core at the default 4.3Ghz speed, underclocking stop all instabilities, even if the voltages were auto.
I could not install a gpu driver until I set the E-Cores to 3.5Ghz, so there's that weirdness. 
Chrome would randomly close, unzipping/unrar would fail CRC checks, but this started slowly over 2 months, it was intermittent, then it got to the point it was constant.
Dropping a 14600k in and running defaults removed the problem completely, I even overclock that slightly which still had no problem, this was on the 2002 Bios I'm currently still running.

Intel also got me to stress test with XTU (BIOS defaults), which it failed within 30 seconds, there was a lot of backward forward communication with steps from them to follow, it was them who felt the CPU had degraded because I'd been running the same safe settings from launch.
Sent me a new one, which has been fine...

Sadly I wanted a long term reliable CPU, a set and forget setup like the 10900k was, 100c under a 360 AIO out of the box with Intel defaults, that's what we got.

I attached a screenshot of my HWinfo so you see what my current CPU is doing, and how I've got it setup.

To speak to temps…. Im seeing impressively low temps on 13900kf and also my new 14900kf.   Usually around 54 Celsius is my average doing regular tasks.   Noctua cooler.  

[schoolofmonkey]

I wish, I've had 2 really average 13900k's now,.
I'm in Australia, so these are coming out of Malaysia, all been really power hungry, SP in the 90's, I know I'm not alone in this.

Originally I thought it might of been by 360 AIO, so I tried 3, all are around the same temps with a contact frame.

Did you take note of the SP score? You have to realise that the vast majority of users do not have this problem.

[schoolofmonkey]

There was a few in the Asus Maximus Z790 and Intel i9-13900k/14900k - An overclocking and tuning guide. at overclock.net that has similar issues maintaining the 5.5Ghz at heavy load (Cinebench etc) and wanted to draw over 300w to do so.
Also the same people had weak E-Cores.
P-Cores are fine once you tame the E-Cores and it was the E-Cores that degraded no the P. on my previous CPU.

Here's the current 13900k SP Ratings.
