NVIDIA Points Intel Raptor Lake CPU Users to Get Help from Intel Amid System Instability Issues
According to a recently published help guide, spotted by the X/Twitter user @harukaze5719, NVIDIA has addressed reported stability problems users are experiencing with Intel's latest 13th and 14th generation Raptor Lake Core processors, especially the high-performance overclockable K-series models. In a recent statement, NVIDIA recommended that owners of the affected Intel CPUs consult directly with Intel if they encounter issues such as system instability, video memory errors, game crashes, or failures to launch certain applications. The problems seem particularly prevalent when running demanding workloads like gaming on Unreal Engine 5 titles or during shader compilation tasks that heavily utilize the processor and graphics capabilities. Intel has established a dedicated website to provide support for these CPU instability cases. However, the chipmaker still needs to issue a broad public statement and provide a definitive resolution.
The instability is often attributed to the very high frequencies and performance the K-series Raptor Lake chips are designed to achieve, which are among the fastest processors in Intel's lineup. While some community suggestions like undervolting or downclocking the CPUs may help mitigate issues in the short term, it remains unclear if permanent fixes will require BIOS updates from motherboard manufacturers or game patches.
Update: As the community has pointed out, motherboard makers often run the CPU outside of Intel's default spec, specifically causing overvolting through modifying or removing power limits, which could introduce instabilities into the system. Running the CPU at Intel-defined specification must be assured with a BIOS check to see if the CPU is running at specified targets. Intel programs the voltage curve into the CPU, and when motherboard makers remove any voltage/power limits, the CPU takes freedom in utilizing the available headroom, possibly causing system instability. We advise everyone to check the power limit setting in the BIOS for the health of their own system.

Once you dial in the settings the chips run great.
Funny thing is Asus used to be the only brand that enforce Intel limits, until recently
If Intel was not aware that pretty much all motherboard makers remove power limits on their Z board, that's just sheer incompetence
Yeah well last I saw a popup after activating xmp profile pops up and asks for permission to do so
If you or anyone else doesn't want the additional feature enabled I'd say click no hehe
Otherwise disable it or stick with optimized defaults F5 I believe where none of this is enabled and this is called Stock configuration lolYeah that is a very brief window where that may happen
You can't even make it all the way through R20 without dropping off that.
A couple of Bios' later they allowed the choice between no-limits and Intel settings. But the default mode (i.e. after every bios upgrade) was (and I guess still is) no-limits.
Also Asus default Current settings (iccMax) were 511Amps; I think intel is either 320a or 400a
No it's not unlimited
Timer limit is 448 seconds
There's an update towards the middle of the page about what to change.
Also just an FYI for Intel users. I recently built a 14700K and Asus mobo system and any instability I experienced was coming from a Thermal Grizzly contact frame. I put the stock ILM back on and it was solid after that. I had Intel's limits in place the entire time, not the mobo auto setting.
1. Intel stock, listed as "boxed cooler", at 253W/320A
2. Tower air cooler, 288W/512A (I use this for 24/7 as it's good balance between performance and thermals)
3. Water cooler, fully unrestrained at 4096W/512A
I bet a lot of people with dinky AIOs pick #3 thinking it'll be fine as "they're on water anyway"
So yeah, better use the Boxed Cooler setting.
Heck I set 150W TDP since the first day I got the 13700K ;)
What kind of sustained clock speeds do you achieve at a 150W power limit?
I'm leaning more and more towards "HEDT" for productive works, even though I don't need many cores. Xeon-W tops out at 4.8 GHz. The IO and memory bandwidth is compelling, but I wish they could reach ~5.5 GHz at stock, then the choice would have been much easier. (things may change though with Zen 5, Arrow Lake and upcoming Xeons)

Remember that Intel's stock values are extremely conservative. 253 W is not excessive for these chips. It'll probably be able to take 400 W constantly without any problems.
A happy i5-12400F (CPU @ unlimited wattage but with no OC + RAM @ XMP-3200 C17) user dialling here. Everything is rock solid. Perhaps a wee slow by someone's standards but as my only significant CPU load is gaming and I'm a 60 FPS gamer, 12400F will be overqualified for a while.
Wondering how hard my CPU will be destroyed by i5-19400 or whatever they will be called. Agree with everyone who states the mobo makers must never default to insane OC on their motherboards.
instead of AUTO,
seeing how virtually every brand had different ideas on PBO limits for ryzen,
or my Gb Aorus running at 101 BCLK with way too much soc V, using auto.
The CPU is configured to run efficiently as possible, I spent some time on power profiles optimising how it adjusts clocks, uses cores etc. and day to day have HT disabled (not in bios but dynamically via windows power settings).Plus the odd vendor *asrock cough* setting tjmax to 120C on Auto.If it ends up being temp related (cause of voltage degradation), it would be interesting. They have an employee on a popular youtube channel telling everyone 100C is no problem for day to day usage.Yeah typically I have about 200-300W total draw across entire UPS whilst gaming, this includes monitor and some non PC devices. So I am running no where near limits, and this isnt by accident, I remember posting on here a screenshot of what happened on the dune spice wars map screen when I switched to my low power GPU profile and it knocked almost 100W of the power draw of GPU without any performance loss. To me, undervolting and power limiting (voltage curve optimising on GPU) is standard process now, the manufacturers just dont care on this side anymore.
I started to investigate with the basics on the hardware side and found that the PCIE riser wasn't seated fully. Doh....
Now it's 100% stable, but getting some artifacting on some game menus. No crashes though. More investigation needed but it's a start.
Their top end CPUs thermal throttle right out of the box. They run over 100C under full load.
The frames per watt of their top end CPUs is not even HALF that of LAST generation AMD. Let alone Zen 4.
Their power consumption is higher than the equivalent AMD CPUs in productivity tasks, and the gap gets much bigger when it comes to gaming.
What about these facts says anything but "we had to match AMD with what we have right now"?
