Constant crashes after CPU replacement

[Merbz]

Hi,

I made an RMA request to AMD and they changed my older faulty Ryzen 5 1600 AF for a new Ryzen 5 1600 AF. Before asking for a replacement for my CPU, I tried isolating every potential issue cause in my system and swapping out components (RAM, AMD and Nvidia GPUs with a clean driver installation, reinstalling windows, reinstalling my softwares). I also tried my components in another rig that had a Ryzen 3 2200G and AsRock B450M Pro4 and did not have any issues. This made me come out to the conclusion that the problem comes from my CPU or my motherboard.

 

After installing the new CPU, my pc started with a frequent blue screens when I booted windows but after making my windows and GPU driver updates it reduced the frequency of occurence. Then I booted up Genshin Impact to test some casual gaming and see if the jitters and lags that I was previously experiencing were also happening with the new CPU but started having other issues.

The same scenario happened 7-8 times where only had Firefox and Genshin open at the same times; it runs fine from 3 to 15 min where there is absolutely no jitter or lag then one of the two software randomly shuts down without an error message or I get a BSOD.

 

BSOD details :

 

I have read online that a windows installating is not necessary when switching CPUs and I honestly don't know if reinstalling windows would fix the issues because it's the exact same CPU (similar to removing it from the motherboard socket and putting it back in place) and I did not do any extra hardware modification in my setup while waiting for the new CPU to be shipped back. I reinstalled both softwares but it did not fix the issue.

 

I ran cinebench R23 and had a good single core result but my multi core result is very poor compared to anything I found online (about 1000 pts lower). Same for cinebench R20 where my multicore is even slower than the result I had with my older 1600 AF which is pretty similar to every youtuber's results.

 

R23 results using the stock cooler (expected multicore arround 6000):

 

R20 results using the stock cooler (expected multicore arround 2700):

 

Geekbench results looks good:

I am not runing XMP profiles and I don't have overclocks on any of my parts that could alter the performance of my system. I tried multiple power plans including the AMD ones.

 

List of my components:

Ryzen 5 1600 AF

MSI B450 Gaming Pro Carbon AC

TEAMGROUP T-Force Vulcan 2 x 8 GB 3000 MHz

Sapphire Nitro+ RX 580 8 Gb

EVGA SuperNova G+ 650W

 

Did I get another bad CPU after the RMA?

Is it possible that my motherboard is causing all my issues since this is the only component I my pc that did swap out while using this CPU?

if not, how can I find the cause if my issues ?

 

Thank you in advance for your help and let me know if you need any information.

That's the cause of your lower performance. Ryzen benefits greatly from faster RAM due to the way that its cores communicate.

You should have changed the motherboard then as faulty cpus is a very rare occurance vs a faulty motherboard. Your testing clearly shows that the only component you havent replaced is still in use in the machine so this is pretty much an open and shut problem until the board is replaced.

For bsod diagnostics it would be good to have it off though

IRQL error usually memory related from my experience. Turn off XMP and run it in default 2133, run some test.

Faulty CPU is super rare, let alone 2 CPU in a row, it is close to impossible, so it might be other parts that caused it, very likely motherboard.

Bad PSU can also caused this.

I wasnt running XMP with the previous CPU and did have drastically better results.

Thank you for you answers, I contacted MSI for an RMA for my motherboard. I didn't know that faulty motherboard were more common than faulty CPU.

 

Does any of you have an experience with their RMA ? What I have read is not very reasuring; they often return refubished components and not always in the best shape.
