Determine which component issue

[simonOfAllTrades]

Hello,

I recently built a new PC, have been experiencing many BSOD at random times with random error codes each time. I decided to do fresh install of windows and drivers, but no luck. So I ran memtest86 on both ram sticks in A2 and B2 (motherboard recommended slots). I received 1 error (1 bit) in test 7 during a 4 pass test. Then I tried testing individual ram and slots with results in the table below:

Number of Errors	Slot A2	Slot B2
Stick 1	0+0=0	0+0=0
Stick 2	2+0=2	0+0=0

I ran the 4 pass test twice for each permutation of single slotted ram. Interestingly, only the first set of tests yielded errors for stick 2 in slot A2. So my suspicions are that either Stick 2 is faulty or slot A2 is faulty, however I don't know which is actually (or both). Do I need more tests? I could also try to get an exchange with the retailer for the same ram/mobo and test those sticks/mobo. What are my best next steps?

Ram: G.skill 3200 2x8GB
Mobo: Asus Prime B550M-A Wifi
CPU: Ryzen 5 3600

P.S.
-All the tests were run with DOCP enabled to 3200
-I did have one bent pin in the CPU that I straightened and fit nicely into the mobo (not sure if this would affect the test)

Thanks in advance

Sounds like stick 2 might be marginal (right on the edge of working / not working).

I would confirm that PC is stable if only Stick 1 is used.
Then replace stick 2 (or the pair of sticks).
Or if you have lots of time on your hands, try slower clock speeds and / or higher voltages.

Thank you for the advice. I am going to get some new ram and see if this will be an issue.

Additionally, is it likely that the memory slot of the motherboard A2 is also faulty?

[David (PassMark)]

RAM sticks are a lot more complex than a socket on a motherboard.
So when it isn't clear what is to blame the likely hood of it being the RAM is fairly high.

Good to know! I forgot to ask as well: my bent pin in the CPU, could be a likely cause for memtest errors?

[David (PassMark)]

If the pin on the CPU was a problem, I would expect more errors.

That makes sense.

Update: swapped out ram and ran 3x4 passes with 0 errors total! Looks like the ram was indeed the culprit. Based on your judgement, the CPU is most likely good as well. Thank you David!
