Over the last several months, there have been ongoing problems with instability issues on some desktop 13th and 14th Gen Intel CPUs.

Official Intel Statement: — July 2024 Update on Instability Reports on Intel Core 13th and 14th Gen Desktop Processors

Based on extensive analysis of Intel Core 13th/14th Gen desktop processors returned to us due to instability issues, we have determined that elevated operating voltage is causing instability issues in some 13th/14th Gen desktop processors. Our analysis of returned processors confirms that the elevated operating voltage is stemming from a microcode algorithm resulting in incorrect voltage requests to the processor.

Intel is delivering a microcode patch which addresses the root cause of exposure to elevated voltages. We are continuing validation to ensure that scenarios of instability reported to Intel regarding its Core 13th/14th Gen desktop processors are addressed. Intel is currently targeting mid-August for patch release to partners following full validation.

Intel is committed to making sure all customers who have or are currently experiencing instability symptoms on their 13th and/or 14th Gen desktop processors are supported in the exchange process.

To help streamline the support process, Intel's guidance is as follows:

• For users who purchased 13th/14th Gen-powered desktop systems from OEM/System Integrator - please reach out to your system vendor's customer support team for further assistance.

• For users who purchased boxed/tray 13th/14th Gen desktop processors - please reach out to Intel Customer Support for further assistance.

TL;DR: If you have a system with an Intel Core 13th or 14th Gen Intel Raptor Lake or Raptor Lake Refresh CPU, the first thing you should do is download the latest BIOS/Firmware for your system or motherboard and check back regularly for any other BIOS/Firmware updates.

I have an Intel CPU, am I affected?

• Intel says that only socketed desktop 13th and 14th Gen CPUs are affected.

• Intel claims that 13th - 14th Gen HX/H/P/U mobile CPUs are not affected.

• If you have any other generation of Intel CPU, for example Intel Core Ultra (Meteor Lake), 12th Gen (Alder Lake), 11th Gen (Rocket Lake), 10th Gen (Comet Lake) or any other generation of Intel CPU, Intel says these CPUs are not affected.

I have an Intel 13th - 14th Gen Desktop CPU and I'm having crashes and instability, what should I do?

• First, make sure any crashes or instability are caused by the CPU and not the result of an unstable overclock, faulty RAM, bad power supply, bad motherboard, graphics card or any other hardware or software issues.

• If you bought your system as a pre-built desktop (e.g. from Dell, HP, Lenovo) then reach out to the manufacturer of your pre-built system for additional support.

• If you bought your CPU for a system you've built yourself, then you should contact Intel's Customer Support.

I have an Intel 13th - 14th Gen Desktop CPU and I'm not currently experiencing crashes or instability, what should I do?

• Update your motherboard's BIOS and check regularly for any BIOS updates published over the coming weeks and months. These updates will include the microcode updates the Intel press releases have mentioned that resolve the issue.

• Ensure your power settings within your BIOS are set to Intel's recommend settings

UPDATE - 2nd August 2024

Intel has confirmed that they are extending boxed retail 13th and 14th Gen desktop CPU warranties by two years.

They have also provided more information on the reported Oxidation issues.

Details here

UPDATE - 6th August 2024

Intel has confirmed that they are extending OEM/Tray 13th and 14th Gen desktop CPU warranties by two years.

Details here

UPDATE - 8th August 2024

Some vendors are now releasing BIOS updates for motherboards and systems which contain the 0x129 microcode.

Intel says this microcode update resolves the voltage spikes that occured under certain conditions, subsequently causing degradation to the CPU and that this newer microcode update will prevent degradation occuring in future for non-affected CPUs.

Please check your support page for your motherboard/system and make sure you install the latest BIOS and check regularly for future versions.

UPDATE - 30th August 2024

Intel has released an additional update, confirming that future processors, including Arrow Lake and Lunar Lake are unaffected by the Vmin Shift Instability (what this thread is about) and provided further clarification on which CPUs are affected.

Intel confirms these currently available processors are not affected by the Vmin Shift Instability issue:

• 12th Gen Intel Core desktop and mobile processors

• Intel Core 13th and 14th Gen i5 (non-K) & i3 desktop processors

• Intel Core 13th and 14th Gen mobile processors – including HX-series processors.

• Intel Xeon processors – including server and workstation processors.

• Intel Core Ultra (Series 1) processors

Details here

UPDATE - 25th September 2024

Intel has released an additional update, confirming the root cause of the Vmin Shift Instability issue and confirmed there will be an additional Microcode release (0x12B) that will contain everything included in the 0x125 and 0x129 Microcode updates and will address elevated CPU voltages when in an idle state.

Sorry, this is an exceptionally noob question.

Are 13th gen intel CPU’s that bad? Asking because the computer I bought has one.

CPU Core I7-13700k GPU ASUS Prime OC 5080 Mobo ASUS Prime B760A-AX

I do mostly gaming but also a bit of video/audio editing.

I read nothing good about 13-14th gen intel CPU’s. Is the CPU I have going to hinder me sooner than later? Is there any reason to upgrade the CPU? Would I get any meaningful improvement by upgrading the CPU at this point or is it not a big enough difference to care about for a couple years?

The game may crash on boot on specific 13th and 14th generation Intel CPUs. To resolve this a BIOS update may be required. More information is available here.

Which means that (in no particular order):

• Quite a lot of people still run either unfixed machines or fixed ones which already degraded beyond "repair" (the CPUs cannot be repaired, one has to use the ext. warranty)

• Game devs, especially small ones, still have to handle support issues and upset customers ("Your game crashes, don't blame the CPU vendor!") to no fault of their own

• Intel's way of handling the 13th and 14th gen instability problems in media terms played out just as it was meant to be: No one of the normal folks, not browsing hardware forums and sites regularly, noticed.

• Needless to say: This problem, if it is still caused by unstable 13th and 14th gen Intels, isn't restricted to just this one game title

What to do?

Tech-savy people: Update your BIOS, hope for the best in terms of the health of your CPU, use the ext. warranty period to your advantage, or at least to counterbalance the disadvantage.

Also tech-savy people: If you know some "normies" with mentioned CPU generations and the occasional gaming desire, help them out with some knowledge regarding the needed BIOS update. Even if some of them did see the heads-up, they might shy away from performing this step and, in turn, degrade their CPUs.

They will call on you anyway when they have to replace this part as getting the cooler off and on again is another one of those non-normie steps, right?

Non techies: You are most likely not reading this anyway and only wonder why the game crashes, even after the update. :-/ It's not the game! Contact the folks who sold you the PC.

Added info:

The process of compiling shaders (and, in turn, causing ~100% CPU load) isn't out of the ordinary for game engines. Especially the Unreal 4 and 5 ones happen to rely on that a lot. But this peak load situation then catches some otherwise "stable" systems off guard: In normal use, they might appear stable. Even the later gaming load will be well under 100%. But unstable machines of course never reach this state.

THIS IS UNRELATED TO P/E CORE ISSUES!

Yes. There are issues with the entire 13th/14th gen chip lines. Mobile or Desktop. Dont comment "Is mine affected????" Yes. It likely is. Intel isnt fourthcoming but they said 13th/14th generation desktop and mobile chips. Assume all processors are affected. GOOGLE YOUR PROCESSOR. IF IT DRAWS 65W FROM THE WALL IT CAN BE AFFECTED!!!

Here are the list of the currently affected 13th gen processors. The 14th gen suffer the same problem, so look at the model numbers and just replace the 13 with a 14 essentially.

[Removed list because people arent reading and keep asking.]

These are CPUs that are largely reporting the errors. There MAY be more.

Major edit. This list is not exaustive but shows the MOST issues. News is progressively coming out that ALL models are possibly affected.

Right now it is speculated that the CPUs have possible corrosion/oxidization of the vias (holes in the PCB filled with copper to pass electricity between layers of the PCB) that causes increased resistance and therefore instability when the CPU runs at its full potential.

The current fix for it: Turn down your ram to 4800MHz and turn your maximum boost multiplier to 53.

Yes. You have to neuter the CPU AND the RAM to make sure your PC remains stable.

Intel's largest clients are seeing anywhere between 10% to 50% failure rates of the CPU, failure being unstable enough to cause repeated crashes. Its so bad that some of intel's clients are being FORCED to use AMD at this time. It's that bad. Intel is already doing damage control for those clients, replacing CPU and paying for the labor to do so.

But they have yet to make an announcement because its THAT bad and they are being blindsided by the error report rates of their clients. And because of that, they need to be "careful" because they are extremely liable as the CPUs by a wide margine cannot perform to their advertised specs at this time.

Intel says the failure rate is below 1 percent. That is 100% false at this time per their own clients.

Please be wary of this when buying Intel CPUs at this juncture in time.

Intel is going to release microcode fixes to fix it, but their fix is what I said above. It forces the CPU to run slower.

TL;DR: Intel 13th and 14th gen CPUs are borked in a way they still work but if you stress them a little bad things happen from instability to crashing/BSOD outright.

IT WILL THROW ALL SORTS OF ERRORS. INCLUDING VRAM ERRORS. SO MAKE SURE YOUR CPU IS IN THE CLEAR!

EDIT: For those saying it hasnt happened to them yet, its a degredation of performance/stability over time. It will NOT happen right away.

im deciding between a i5-12400F and a i5-13400F, bute some people said "oh the 13rd generation causes a lot of trouble" and im asking myself, is this generation really THAT problematic?
