Memtest86 giving errors on both rams in both slots

[daqqie]

Hi,

I'm completely stuck based on my memtest86 results and hope someone can help me figure out what my issue is.

My computer was working completely fine for the past year but suddenly started freezing completely when joining new games in Overwatch at first, and later began to happen when casually browsing the internet as well (need to force shut down to get it working).
I tried reformatting the harddisk, updating windows and all drivers but it still continued, so determined to look for the hardware issues using memtest86.

Since the computer is a mini-itx, there are only two ram slots. First I tried running the test with both rams, result was 52% passed (336 errors).
Then I took turns running the test with each ram in the first memory slot, RAM1 had 6 errors in slot 1, and 6 errors in slot 2. RAM2 had 18 errors in slot 1 and 389 errors in slot 2.

Can anyone provide some insight based on the results I have attached? I am currently updating the BIOS for the computer, but I am quite uncertain as to whether it is a RAM issue or MOBO issue or even a CPU issue at this point.
It is clear that RAM2 has a large number of errors, but considering there were still errors with RAM1 in both slots, does that mean I should ideally replace both RAMs? Or is there still a good chance it could be a MOBO or CPU issue?

Would greatly appreciate any help with this as I'm completely stuck.

Please find results below:

Test 13 [Hammer test] Warning

Note: Your RAM may be vulnerable to high frequency row hammer bit flips. However the conditions needed to induce these errors occur only very rarely in normal PC usage, and so this should not be of concern to most users.

Something is definitely wrong with the hardware.

I would have blamed the RAM but to have two sticks go bad at the same time seems unlikely. (if you did have a 3rd stick available, I would still test it however).

Maybe the system is now marginal. Try lowering the RAM clock speed to the 'nominal' speed (i.e. turn off XMP, sometimes called AMP profiles)

Thanks for the response David.
Unfortunately, after updating the BIOS the amount of errors still stayed the same. Based on your advice, I looked into the BIOS settings again and the RAM which is 3000mhz was running at 2133 with XMP off. Since I couldn't lower it any further, I tried moving "RAM1" into Slot1, which was the combination that had the least errors, and turned on XMP (previously it had been off during the other test runs), this resulted in the best attempt so far with only 1 error.
I think this is somewhat usable for now but to have peace of mind I would still prefer to change out whichever hardware component might be malfunctioning.

Based on all of this, do you think we can narrow down the possible culprits to the RAM or MOBO?

Thanks again.

[David (PassMark)]

Can you borrow another set of RAM to try?
If another set was good, then (obviously), it must be the CPU or MB at fault.
