14900k life expectancy

Hi there, I have been purchasing the 14900K on day 1 to use with the old alder lake era Gigabyte Z690 UD AX DDR5 board, so far the performance is amazing compared to the old 12700KF, but I noticed that the VF curve, even if I get LLC to "normal" (lowest) setting, with intel PL1=PL2=253W, the all P core 5.7Ghz profile gies a constant Vcore voltage of 1.37-1.41V on HWinfo, since I use it quite heavily on flight sim and video processing, it literally got almost daily 3-6 hours of full load (non-avx) environment sustaining such voltages, since I am having quite a good cooler (Noctua NH-U12A), the load temperature for AVX load like Cinebench is average in 87-89C with <1s peak of 95-98C on single core, and on normal daily load usage, averaging ~60-65C and with peaks of mid 70s.

 

While the temperature is in the nice range, after various "degradation" of 12th and 13th gen stories out there claiming say, 13600k after a few months of use in constant 1.37v vcore requiring extra 0.04v to get stable and crash free, and that 14900k is just a well binned raptor lake processor, I wonder if in my usage, in a year or so the voltage will needed to be bumped higher to maintain stability? (no idea if the VF curve in bios will adjust for such), can anyone shine some light on the stock VF curve on stock, non-OC profile how long I could expect the CPU to last?

Hello, @Geek_sam  

 

Thank you for posting on the Intel® communities.  

 

The processor has a few internal voltage regulations (FIVR, Digital Linear voltage regulator(DLVR) to support internal power rails. In each processor datasheet Technical Resources: Intel Core Processors, there is a section called “electrical specifications" where you can see average voltage ranges and specifications and understand how volts work on the CPU depending on different stages and based on Intel technology.  

 

Please be aware that these ranges will depend on the system requirements/components and those are average based on tests, not necessarily exact values.  

 

You shouldn't have any problems with the processor if it is used within its specifications. Also, I would like to let you know that altering clock frequency or voltage may damage or reduce the useful life of the processor and other system components and may reduce system stability and performance. If the processor is used outside of its specifications, the manufacturer's warranty may be voided.

Hi there,

 

Thanks for the quick reply, I saw in the specs the operation range is 0-1.72v, so I would assume the ~1.45v under load from the SVID is safe for the processor long term without significant degradation. what I tried last night to dig into the bios is a bit curious, I found that if the power limit is set to the "Intel POR" setting by gigabyte, it limits it to PL1=PL2=253w for the 14900k, but under HWinfo it shows the ICCMax is unlimited, which is obviously can shoot above the recommended 307A in the datasheet. when I do a 10min cinebench R23, I saw the processor was under 90C, and with package power draw limiting on 253W as expected, showing ~40k marks, but then if I manually enter the PL1=PL2=253W and with ICCMax limited to 307 (without unit..), the max power it can draw dropped to ~110w and the mark instantly dropped by half to the 12700KF range of 20k, I wonders if this is something the gigabyte bios naming being confusing, coz in simple maths even 1.25v*307A should be way over the 253W power limit, I wonder if using the Intel POR should be fine and not worry about the "unlimited" ICCMax in HWinfo readings, since even 1v Vcore with 307A should hit the wattage limited before going near ICCMax?

Hello, @pppesss  

 

Thank you for your reply. 

 

Please take in mind that Intel cannot validate 3rd party tools as cannot guarantee they will work as expected. If you use third-party software to measure the temperature or the BIOS readings, contact the software vendor to ensure the software is validated to work with your processor. 

 

We recommend you use validated tools such as Intel® Extreme Tuning Utility (Intel® XTU) to monitor these values, however, I see that you are modifying values that can affect the processor, please take the following points into consideration: 

 

  • The IccMax value can vary depending on other Hardware configurations. Many Motherboard manufacturers set their configuration to default for stable usage and even some include a power limit that can be different from CPU. We recommend keeping it on default. 
  • Intel doesn't design the BIOS or 3rd party tools you are using, we cannot guarantee their information is totally accurate. 
  • As mentioned above, we recommend you keep the system in its stock values and configuration and not alter the processor or system values to ensure its good operation. The processor should not have any problems with its default values or within its specifications.
