Optimizing Stability for Intel 13900k and 14900k CPU’s

Still weird behaviour. At idle both CPU-Z and HWMonitor show the CPU min and max speed at 5.5GHz and wattage around 20w. When I run Cinebench (supposedly a hard-core tester) the values fluctuate between min 4.8GHz and max 5.2GHz, with power at 207w. Maybe I have a false memory but back when I used to OC my rigs a test (Prime-95 mostly) would always push the CPU to the max speed I'd set it at in the BIOS.

Cinebench is a 10-minute test. On the CPU multicore test it scored 1831. Max temp reached was 83c.

I'm completely unfamiliar with a CPU that idles at 5.5GHz with a power-draw of around 20w but will then run at a max of 5.2GHz and a min of 4.8GHz under test.

On top of that, even though the test is finished but with the app window still open, the CPU is still running at 207w and 83c. Now I've closed the app window, no change. I'm going to reboot the PC...

Even at idle, there are dozens of very light background tasks being ran. There always are.
You'll find that it's impossible to see the processor continuously at 0% usage and all the power locked at minimum. It's always being triggered a little, every second or so.

Even the friggin mouse. Try, for instances, just moving around your mouse very frantically, and watch the CPU usage and power increase just a tiny bit in reaction....

Many things happening on background, and that's why that oscilloscope video from Buildzoid is so interesting and important, because it shows the kind of voltages oscillations and spykes that occur, in different situations, that otherwise you may never even see on your regular monitoring software.
And also why sync'ing (limiting) all the P-cores to same clock, to stop this 1.5V+ single/dual core boost BS, is very important.

All that said, no need to overstress yourself with the issue. 
Because, at some point, there is nothing more one can do.  And it gets down to pure luck that your, his and her processor is more or less degraded (if at all), thanks to Intel.

Everybody (those aware of the issue, that is!) with 13th and 14th gen CPUs that are over 65W is waiting for the Intel microcode to be released.
All will need to install it, no buts or ifs.
Supposedly the degradation will be stopped with it.  But, if there are signs of damage already, then no microcode will save it, and it's RMA time for the CPU. 
And, sadly, that's about it.

If I had such a CPU, make it so it can be RMA'ed, sell the board and go to the "other" company.

 

Honestly, would you feel comfortable with a CPU that can fail any moment ?

 

Damocles comes to my mind

Intel can either choose to RMA, or make my next System AMD

They SHOULD be aware which batches are affected and inform their customers to RMA them, no if's, but's, or maybe's

And a lot of their customers aren't technically inclined enough to perform the task Intel should be doing and have to pay some computer tech to do it for them

I'm not seeing any information from intel that they are gonna foot that bill

I’m using the MSI MPG Edge Wifi DDR5 and now have this voltage issue under control. For those who can cross interpret this info here are my settings.

- Using the latest non beta released microcode. Profile set to MSI performance 253W. Wattage capped at 253

- Voltage capped at 1.33v

That’s it. Load Lone Calibration and “Lite Load” are both on auto. Everything else is on Auto. core clocks are in the 5.6/5.7 range

HWINFO64 reveals Core VIDs under 1.4 (that’s just the voltage the cores are ASKING FOR. It doesn’t mean they are getting it)

Vcore voltage max is 1.238-1.3. Average Vcore hovers in the 1.1 range.

Under load nothing exceeds 1.3 volts and temps don’t even reach 70c except for a brief spike when Windows starts up. DCS runs cool with temps well under 70c no stuttering and no lock ups or CTDs. 
 

PM me if you want to know more.
