Faulty Ryzen 7 3700x

I purchased a brand new Ryzen 7 3700x and successfully installed it in a new build. From the first day, I would get BSOD with code WHEA_UNCORRECTABLE_ERROR, and have been checking all hardware parts to find the issue. It turns out the processor was the issue as I switched it out with a Ryzen 5, and had no errors after. Drivers have been checked. The hardware has been checked and looks brand new. Is this something covered by the warranty? Also how long does that take to receive the replacement?

Re: Faulty Ryzen 7 3700x

If you think it is defective, you should seek your consumer rights. However, if I were for you, I would reset the BIOS to factory settings and set the CPU Core Ratio value to 35. In this way, you will underclock the CPU and test whether the processor is stable. If stabilization is provided, the appling of core voltage of the motherboard is not correct. And this problem may happen to you again in the future.

Re: Faulty Ryzen 7 3700x

You are not alone many have had this issue and a good chunk of them find it is CPU related. If you are still in your return period then see if you can exchange it with the retailer. 

I think a while back when I had a cpu rma'd with AMD it took about 4-6 weeks. 

I would never tweak anything away from defaults to get a new CPU stable. If you have to do that then you have a board, cpu, memory or power issue. If it isn't running right at defaults I would question the longevity of the chip under any altered settings. 

No reason to do that when you have the full right to get another CPU. 

If you need the RMA form link here it is:  https://www.amd.com/en/support/kb/warranty-information/rma-form

Re: Faulty Ryzen 7 3700x

Do not attempt any RMA operation on your hardware without running any tests. There are also many users on these forum pages whose results do not change despite the CPU-RMA. You need to find the cause of the problem. In addition, the probability of a CPU being produced faulty is extremely slim.

Re: Faulty Ryzen 7 3700x

No it is not slim and is the most likely culprit this is not opinion but based on tons of threads at this point of users having this same issue. You however don't agree with any of them even when they tell you it is the CPU.

Re: Faulty Ryzen 7 3700x

OP feel free to follow whatever advice you like. I would suggest talking with the support department of your motherboard and take their professional opinion. Don't get sucked down the rabbit hole of listening to users who would have you changing everything under the sun in an attempt to get it to work. Sure if you cripple your performance of the cpu, you may get it more stable. That is possible. Sure if you never use PBO or XMP it may be more stable. To me I wan't my stuff to work at defaults as advertised and when buying new, there is no reason to settle for less than that. 

You can also talk to AMD support about this too. They VERY often suggest RMA on this issue of the CPU so no it is not a slim chance. https://www.amd.com/en/support/contact-email-form

------------------------------------------------------------

That is from Intel docs...

How to fix it:
The error WHEA_UNCORRECTABLE_ERROR means that your system shut down to protect itself from data loss,. The error happened due to a hardware issue.

To fix it, try the following:

Get the latest updates with Windows Update. Go to Settings --> Update & security --> Windows Update, and then select Check for updates. Reboot system.
If that does not work, try the followings:
Set the BIOS to its default values. Reboot system.
Start Windows in Safe Mode, and check if there are any driver errors in the device manager.
Check if there are any hardware issues.
Try to boot with minimal hardware settings (for example, one DRAM, less hardware components on your system).
Try the Windows 10 app called Windows Memory Diagnostic to check for memory issues.

That is from Easeus...

What Are the Causes of the Whea Uncorrectable Error
What causes the Whea uncorrectable error? The Whea uncorrectable error is one type of BOSD error. This error is usually caused by five reasons:

BCD error
MBR or system file error
Driver issue of hardware
Faulty hard drive, or Processor
Low CPU voltage or overheating CPU

------------------------------------------------------------
System components, frequency of error message you got, and what caused this error are unknown. And while a low setting of a motherboard BIOS is very likely to cause this error, changing the CPU probably won't fix the problem.


If your processor is working properly at low speed, it will work very comfortably at the factory settings with a suitable BIOS setting.

OP you may find these threads helpful. They are full of people with your error message. Many different possibilities of the cause are discussed and things they tried. 

Those thread links:

 

This reddit thread has many users involved where replacing the CPU seems to fix the issue.

Re: Faulty Ryzen 7 3700x

Each processor is produced like baking a cake on a tray. Processors with good silicon quality are introduced to the market with the phrase x or k. And it is very unlikely that the silicon quality of these processors is low. And these processors are tested with a proper voltage and released to the market. In particular, WHEA errors are caused by the fact that the processor's voltage curve showing what speed and what voltage is applied is not smooth. Corrupted RAM may cause. Corrupted disk may cause.

The presence of people mentioned on other forum pages who think that the CPUs are produced malfunction does not make this situation so easy to go to CPU failure without knowing anything.

Re: Faulty Ryzen 7 3700x

Again follow any advice you like.

Yes it can be caused by lots of things. However in the past quarter there has been a big uptick with this issue. Most of them having new systems. So those people that worked with their motherboard manufacturers support departments and AMD support who suggested the CPU be changed must all be wrong and you are right. 

There is no doubt it is a vague error that can be lots of things including but not limited to malware, file system corruption, memory issues, power issues, mother board issues, gpu issue and cpu issues. 

However lately there have been a lot of cpu issues across the tech forums on the net. With far more often than not the cpu being the culprit. It doesn't hurt to check all things. 

Now he picks on the links for reference I supply the OP not to him. I didn't even participate in any of those threads. Yet anything I touch he says is wrong. 

OP please understand he has an issue with me and everything I say. Although not just me he tells others they are wrong all the time too.  Like I said don't take my word. Talk to the support departments for your hardware. They are the professionals and I am quite sure they will be happy to help you with this issue. 

If you want to see which one of us in these forums offers users the most constructive help I suggest you look at our profiles and at his customer awarded badges of zero and I am in 9th place with most badges out of thousands of users on this site and his expert badges or 2 compared to my 59. 

I am not saying any of this to brag. Just getting really sick of him picking a fight with only his advice being the plausible good advice and rarely and I mean rarely when you go back through the threads this user is involved in do users come back saying his advice was correct.
