procesor i9 14900KS

[Dominnn84]

mój procesor nie osiąga swoich zegarów w każdym teście Cinebench R23, czy cpu-z ma taktowanie P5500MHz/E4300MHz,
dopiero gdy obniżę napięcie w biosie zegary zaczynają rosnąć w testach, ale staje się niestabilny, czy ktoś może mi wytłumaczyć dlaczego tak się dzieje? Czy to wina mikrokodów i aktualizacji BIOS?
Nie wiem, co to ogranicza
Posiadam płytę główną MSI z790 Carbon WIFI
Procesor i9 14900KS
DDR5 Kingston 6000 GHz RAM
Karta graficzna MSI RTX 4080
Zasilacz ROG 1200

Thank you for posting in the community. To better understand and analyze your situation, I have a few questions that I would like you to address:

1. Could you please confirm the current BIOS version installed on your motherboard?
2. You mentioned that the system becomes unstable when you lower the voltage. Could you provide more details on this instability? For example, what specific symptoms are you observing?
3. Is your BIOS configured to "Intel Default Settings"?

Additionally, I recommend using the Intel Extreme Tuning Utility (XTU) for a stress test. Please follow these steps:

• Run the stress test for about 30 minutes.
• During the test, click the yellow "File Logging" button located in the middle left corner to start recording.
• After the test, click the button again to stop the recording.
• You can find the Excel file by clicking the folder icon next to the button.

Once you have the log file, please send it to me. This will allow me to review the stress test values and provide further assistance. You can check the image below for your reference.

Before the microcode update, the processor was working correctly.
And after the BIOS update, the clock speed dropped.

The processor and graphics card are liqiud cooled, I have no problem with temperatures  

[PC1997]

Depending on how old your previous BIOS was it may have been overclocking the processor without you knowing it, hence your scores and clock speeds were higher underload. The latest microcode (0x12B) will reduce performance about 5-7 percent compared to the original microcode. Also, motherboard vendors have reduced power levels considerably in their lastest power profiles and, most importantly, set the Intel power profile by default. I see your MSI board has set the extreme profile (320W PL1/PL2 & 340A) this is what is limiting your clock speeds...

Disclaimer: ------> if you are not already aware, you should be warned that degradation of your CPU is highly likely when you start pushing the voltage and current (amps) too high with Rapter Lake CPUs. Indeed any processor past a certain point.

So those three mentioned values are primarily what is holding your CPU back: PL1 / PL2 & amps must be set higher (if your cooler can even handle it...direct die cooling is pretty much mandatory with higher power settings). And chilled deionized water is preferable as well. Basically you have to push the Nitro to support an all-core workload at extreme clock speeds (450W+). In fact, the 14900KS can easily exceed 500W, depending on bin sample, when pushed to the maximum. And, in so doing, WILL degrade, least you have liquid nitrogen cooling.

You've been warned. If you want your cpu to last - DO NOT do this. I have already degraded both my 13900KS and 14900KS chips chasing benchmarking scores. And it is not even worth overclocking for gaming. If productivity is your thing, you either should be satisfied with the performance of the processor out of box or buy a faster cpu rather than overclock it and have it degrade producing errors. If you want your cpu to last, load the Intel Baseline default power profile (PL1 150W/PL2 253W/307A) or the Intel Performance profile (PL1/PL2 = 253W) at most.

Hello Dominnn84,

Thank you for sharing this information with me. I'm curious about a few points: If you don't lower the voltage, do you consistently achieve P5500MHz/E4300MHz while running Cinebench R23? Additionally, when the voltage is not lowered, does your system encounter any issues, or does it operate normally?

I installed a new system, I have no problem with processor instability, as I said earlier after updating the bios and the settings recommended by Intel 320W/320W, iccmax 400W reaches such clocks in cinebench r23, I also sent a MonitorLog recording from XTU as you asked, there you can also see what it has under load.

Hi Dominnn84,

I understand. I will look into this performance loss further and provide you with an update as soon as possible.
