Intel Statement on Stability Issues: "Motherboard Makers to Blame"
A couple of weeks ago, we reported on NVIDIA directing users of Intel's 13th Generation Raptor Lake and 14th Generation Raptor Lake Refresh CPUs to consult Intel for any issues with system stability. Motherboard makers, by default, often run the CPU outside of Intel's recommended specifications, overvolting the CPU through modifying voltage curves, automatic overclocks, and removing power limits.
Today, we learned that Igor's Lab has obtained a statement from Intel that the company prepared for motherboard OEMs regarding the issues multiple users report. Intel CPUs come pre-programmed with a stock voltage curve. When motherboard makers remove power limits and automatically adjust voltage curves and frequency targets, the CPU can be pushed outside its safe operating range, possibly causing system instability. Intel has set up a dedicated website for users to report their issues and offer support. Manufacturers like GIGABYTE have already issued new BIOS updates for users to achieve maximum stability, which incidentally has recent user reports of still being outside Intel spec, setting PL2 to 188 W, loadlines to 1.7/1.7 and current limit to 249 A. While MSI provided a blog post tutorial for stability. ASUS has published updated BIOS for its motherboards to reflect on this Intel baseline spec as well. Surprisingly, not all the revised BIOS values match up with the Intel Baseline Profile spec for these various new BIOS updates from different vendors. You can read the statement from Intel in the quote below.

Intel has observed that this issue may be related to out of specification operating conditions resulting in sustained high voltage and frequency during periods of elevated heat.
Analysis of affected processors shows some parts experience shifts in minimum operating voltages which may be related to operation outside of Intel specified operating conditions.
While the root cause has not yet been identified, Intel has observed the majority of reports of this issue are from users with unlocked/overclock capable motherboards.
Intel has observed 600/700 Series chipset boards often set BIOS defaults to disable thermal and power delivery safeguards designed to limit processor exposure to sustained periods of high voltage and frequency, for example:Intel requests system and motherboard manufacturers to provide end users with a default BIOS profile that matches Intel recommended settings.
- Disabling Current Excursion Protection (CEP)
- Enabling the IccMax Unlimited bit
- Disabling Thermal Velocity Boost (TVB) and/or Enhanced Thermal Velocity Boost (eTVB)
- Additional settings which may increase the risk of system instability:
- Disabling C-states
- Using Windows Ultimate Performance mode
- Increasing PL1 and PL2 beyond Intel recommended limits
Intel strongly recommends customer's default BIOS settings should ensure operation within Intel's recommended settings.
In addition, Intel strongly recommends motherboard manufacturers to implement warnings for end users alerting them to any unlocked or overclocking feature usage.
Intel is continuing to actively investigate this issue to determine the root cause and will provide additional updates as relevant information becomes available.
Intel will be publishing a public statement regarding issue status and Intel recommended BIOS setting recommendations targeted for May 2024.

Intel themselves deliberately made these performance claims with out-of-spec settings, and the final product received by the customer only sustain stable working condition with precisely half of the power setting (PL1 253 vs PL1 125) they've demonstrated in product disclosures and advertisements.

this is what the mainboardmakers where unable to understand or did plain ignore.
read the notes and remember the "Extreme Config" is for i9 only
I really hope that somebody sues Intel and its partners over this. The case doesn't even have to succeed, it just has to shine enough of a light on these bullshit practices to ensure that Intel stops doing them for good. Just build a CPU that isn't fucking garbage, if AMD can do it why can't you, Intel? Clowns.
Everything else is mobo maker deviation.
You posted Igor's table and claimed that is the spec with PL1 not = PL2.
Now you are saying they should be configured as advertised PL1 = PL2.
why the contradiction ?
This is what I originally said in my first post two weeks ago. The only blame that can be attributed to Intel is not being firm enough with board partners. Having the option to change things is preferable. Having things changed out of the box by default is not.
I'm pretty happy with my CPU now, after literally 1 year full of trouble... I'm not problem free, as i have mentioned, but at least it's all performing perfectly during gaming. You can't beat smooth gaming with 40Wats of power, the CPU is magical, the whole platform.... not so much. At least i don't suffer from the famous USB issues with AMD, god knows i have enough problems as it is lol. Not that intel is better in the last few years, its very clear i went with the right CPU this time. My previous CPU was it-2500k, which was better and cheaper than what AMD was offering in my country. Who knows, maybe Intel will do another good one in 2030, just in time for my next upgrade?
Steve gives the most compelling argument, and evidence, as to why Intel is mainly to blame for this power and overvoltage mess.
DM me if you want, I boot in about 45 seconds. Once you get to Windows it's very fast, it's the BIOS POST that takes ages.
Yeah, the early AGESA for any AM4/5 platform is generally pretty rough. Agreed with 7800X3D being good, platform being mid.
'nuff said :D
This nonsense makes me wanna go back to my trusty ole i9-9900k's, of which I still have 1 rig running overclocked from the base 3.6 to 5.2Ghz for over 4 years now (w/360mm AIO cooling & lots of case airflow) notta problemo :)
make a "patch" BIOS every later then - SURE, GOOD IDEA!:roll:
Just because Maytag ovens are used to cook food doesn’t mean they are responsible for what’s cooking in them.
That analogy applies here as foxconn would never touch much less change any settings in the shipping default BIOS. That’s all Intel. Same goes for third parties today. None of them would risk shipping a default BIOS without at least checking with Intel. Not for permission mind you but at least approval that it wouldn’t causes issues or void warranties.
There's a spec, it's what the motherboard makers should be using.
They are not (even after their "intel baseline spec" BIOS update).
Pretty clear cut factually.
Intel needs to be firmer with enforcing their spec, and dictating how deviations should be presented. That's the issue.
They at least seem to be taking that stance now. For the inevitable "but Intel in their own marketing uses off spec numbers" comments.
The only change from spec is PL1=PL2.
Not -
- Disabling Current Excursion Protection (CEP)
- Enabling the IccMax Unlimited bit
- Disabling Thermal Velocity Boost (TVB) and/or Enhanced Thermal Velocity Boost (eTVB)
- Additional settings which may increase the risk of system instability:
- Disabling C-states
- Using Windows Ultimate Performance mode
- Increasing PL1 and PL2 beyond Intel recommended limits
And other "optimized" defaults, often including automatic overclocking of the CPU clock, BCLK, even RAM timings.Changing the voltage curve is a significant thing. Both going under and over the recommended values.
Setting PL1 to PL2 is not major. The CPU is already validated to that wattage, and protection features put in place will automatically downclock/reduce volts etc, if thermals become an issue. Unless those protection mechanisms are turned off by the motherboard manufacturers, by default.
There's a big difference between allowing the CPU to run at the PL2 all the time (253 W), with PL3/PL4 still topping out around ~300 W, to having non standard voltage curves and PL=4096 W/unlimited.
The other end of the spectrum is these modified clock tables/curves causing vdroop that goes below the Intel recommended spec. This is another cause for crashing that Intel mentioned.
This news post comments about facts.
Could you please provide the said 'marketing uses materials' from Intel showing 'They did not tweat any of these settings besides PL1 = PL2' ?

It's factually incorrect to say they weren't not only aware but 100% on board with what was going on and this why I believe they likely even encouraged it.
edc.intel.com/content/www/us/en/products/performance/benchmarks/desktop/
What is speculation is this part. Not the comment that Intel is aware of what motherboard makers were doing.
In fact, the vast majority of those benchmarks on that page do not use PL1=PL2. Each time the configuration is a little different and it's very clearly stated. E.g. some have Intel APO enabled.
For example, the second entry in the list.
What is also notable is that these performance claims are in line with TPU testing, which uses Intel spec. So there isn't any reason, in my mind, to imagine for drama's sake, that Intel is running a bunch of other parameters outside of spec, but not stating that.
