July 2024 Update on Instability Reports on Intel Core 13th and 14th Gen Desktop Processors

[Thomas_Hannaford]

*9/25/24 - Please go to the following link for the latest updates: Intel Core 13th and 14th Gen Desktop Processor Vmin Instability Issue Root Cause*

*Update 8/26 clarifying support guidance for Intel Core 13th/14th Gen desktop tray CPU purchases*

*Update 7/29 regarding customer support process guidance (included below as well): https://community.intel.com/t5/Processors/Clarification-Update-on-Intel-Core-13th-14th-Gen-Desktop/m-p/1618462

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

What voltages and temperatures do you see under load?

please bear in mind that a power or current limit will not reduce the voltage on a single core boost.

Use HWinfo and check your maximum temperatures, VIDs etc.

It might be necessary to reduce the maximum boost frequencies to protect the CPU.

VIDs around 1.5V or more would not be good for your CPU. Try to keep voltages below 1.4V, or even less.

Do this, then wait for Intel to fix the microcode to basically do the same thing. Trying to reduce voltages to save your chip

I agree that the KS is a flawed product and that is of course Intel's fault.

[ysk_PLUZ]

cinebench r23実行時は1.230V　パッケージ温度は86℃です。

毎日10時間程度使用していますが、交換してすぐはHWinfoのCoreVIDsが最大1.381V程で推移していましたが、交換後1ヶ月経過した現在では同じ設定で最大1.495Vが記録されています。

>CPU を保護するために、最大ブースト周波数を下げる必要がある場合があります。

AMDとの比較で最大6.200MHzを宣伝しておいてユーザー側で周波数を下げなければならないのは

優良誤認としか言いようがありません。

また、マイクロコードがリリースされたとしても劣化が回復するわけではないので

ユーザーは劣化をごまかしながら使用する事を強いられます。

[CoolBook]

Perhaps you accidentally installed a new BIOS with that new Intel profile which is increasing voltage for "stability"?

That is probably what's making this issue even worse for users.

I would personally restrict my chip from ever reaching 1.5V.

Who even needs 6.2GHz?

Disable HT, lock all cores at a lower safer frequency (below 1.3V) and your CPU would be much faster in reality.

All that frequency changing up and down is not free. So ignoring that would often give you a faster CPU.

Now you render stuff, so keep HT. For the regular gamer, disabling is better.

[ysk_PLUZ]

今以上電圧を下げると正常に機能しません。

マイクロコード0x125を含むBIOSにアップデートしましたが、各数値はアップデート前と同じ数値にしていますし、アップデート前からVIDは上がり続けています。

そもそも6.2GHzが必要か否かは問題ではなく｢6.2GHzで動作します、でも壊れます｣が問題なのではないでしょうか？

[CoolBook]

I think you misunderstood. You should not use the offset or similar that affects all frequencies.

You set maximum P-core frequency to a lower value. What do you run now? 6.2GHz for 2 cores?

Well, whining doesn't really improve anything, does it?

Sue Intel if you want to, but that won't fix your computer today so you can continue with your work.

[ysk_PLUZ]

VFカーブで7~10の電圧を下げています。

 2コアで6.2GHzです。より良い低電圧の方法があれば教えていただけるとうれしいです。

私は愚痴を言っている訳ではなく、責任はユーザーに無いと言いたいだけです。

集団訴訟の話も聞いていますので、私が訴えるまでもなく訴訟は始まのではないでしょうか。

[CoolBook]

You have to limit the maximum frequency from 6.2GHz to something lower, like 5.8GHz.

That way the maximum voltage the CPU will be exposed to will reduce according to VF curve.

[ysk_PLUZ]

ありがとうございます。

電圧とともにシングルの性能も落ちないといいですが…

[CoolBook]

The whole idea is to reduce the top frequency. Yes, the performance will drop slightly.

Since you work with video etc. single core performance would not matter that much.

This is to reduce stress on your CPU until the patched microcode is released. If you don't want the CPU to degrade.

Otherwise you could continue as before. Just RMA again when the chip is bad.

Or you could turn off your computer and do something else while waiting for the patch

[ysk_PLUZ]

ありがとうございます。

事前に言っていなかったのは申し訳ありませんが、グラフィックデザインも同時進行しているので

シングルも重要になってきます。それを考慮してこのCPUを選びました。

パッチが出るまでに不具合が表面化することがあればRMAを考えますが、表面化しなければ

｢劣化はしているがRMAを許可されない｣という状況が懸念されます。

私の他にも同じ状況に陥るユーザーは多いと思うので、そういうユーザー向けにもしっかり案内がほしいと思っています。

色々と説明していただきありがとうございました。

[CoolBook]

I don't think you single thread performance will be an issue.

Throttling is also very bad for performance.

What is your current Speedometer 2.1 score with latest Chrome?

This is from an 13700k.

[ysk_PLUZ]

Speedometer 2.1初めて知りました。

[CoolBook]

That was a very low score. Perhaps your computer is overheating all the time?

What browser is that?

[ysk_PLUZ]

アイドル時は35℃前後　Speedometer 2.1実行時は65~75℃程でした。

加熱しすぎでしょうか？

ブラウザはChromeです。

[CoolBook]

Yes, that is all P-cores locked at 5.7GHz with HT off.

My everyday setting is locked at 5.5GHz no HT.

Undervolted as much as possible and 32GB 6600MT/s CL32.

[berkkocaturk]

He paid for that performance why should he limit his cpu. If it doesnt work its not what he paid for intel should refund it.

Its like buying moldy bread and just cutting the moldy part and eating the rest.

[Aldariann]

"Average user" could use previous KS version with optimized motherboard settings for YEARS without problem.

It clearly is an issue with latest 2 generations of K.

[CoolBook]

Yes, especially the 14900KS is broken.

The problem is that the K-SKU (unlocked for overclocking) became some sort of "out-of-the-box pre-clocked to the max" part.

On top of that there is no actual fine tuning, but instead some brute-force idiotic suicide voltage settings.

We now know how well that worked

The K was sold at a premium to be unlocked, meaning that the customer was allowed to tweak it.

If that is what you do with gen 13/14, then the vast majority of the chips would probably last a very long time.

I mean, just follow the basic instructions and you are all set.

Instead the K CPUs and Z motherboards became the basic standard that everyone is buying.

At least Intel should operate K at the same settings as the non-K. Then it would be up to the user to enable overclocking after agreeing that it is risky and voids the warranty.

I think the poor handling of the latest K/KS will result in all locked CPUs again. The current situation is just not sustainable any longer. Otherwise you would have to get a license to use these parts in the future

[Xav1erSue]

Does the voltage increase caused by the microcode bug refer to a situation where the actual operating voltage is higher than the CPU's working voltage (including overclocking voltage)?

Will fixing the microcode bug result in a decrease in the original CPU core frequency? The fundamental issue is whether this fix can truly solve the problem or if it is simply a limitation on the core frequency. The latter is clearly unreasonable.

[Amosf]

I noticed that the instability of the cpu does not come from the voltage. Myself i own the new 14600kf and yes the voltages are a bit high, i undervolted it from 1.295 to 1.150 volts in boost but still had the instability issues. I noticed that the cpu became unstable because of the wattage settings in the mother boards. Those are sett on unlimited. I manually put it on the recommended wattage that is 181 watt on max and the issues are gone. Stable and cool!

[Aksel]

i have the same CPU and it runs at 1.35 volts, eventhough the pc runs fine with no issues, my max temps is 81°c, i'm still afraid that the voltage will damage the cpu if it's exposed to it for a long time since it's just too high, undervolting for me didn't work since i lose half performance even at 1.21 volts, the power limit is enabled by default by my motherboard so it doesn't exceed the max wattage, i'm i doing something wrong with the undervolting? it seems it's different for each CPU even if it was from the same Gen and family, i've seen videos online of the same cpu with runing with 1.1 volts by default but for me even in the bios it runs at 1.35 volts
