RAM issue?

[estate]

Hello,

I recently bought new RAM and installed it into my PC and I have been getting BSOD ever since. I changed back to my old RAM and the BSOD problem hasn't gone away.


There is a lot of tests I have run so I will try to explain it as clearly as possible. I am running the version of MemTest86 that is provided here: https://www.memtest86.com/index.html.

My testing is comprised of two computers. My daily driver and a friends. All of my tests are 4 passes and all 13 tests. The default settings for all tests.

Summary of tests and results (I used XMP for all tests):

My Computer

TEST #1 - FAIL
I tested my old RAM 2x8GB @ 2400 - Slots A2 B2

TEST #2 - PASS
I tested my friends RAM - Slot A2

TEST #3 - PASS
I tested my friends RAM - Slot B2

TEST #4 - PASS
I tested my old RAM 2x8GB @ 2400 - Slots A1 B1

TEST #5 - PASS
I tested my new RAM 2x8GB @ 3200 - Slots A2 B2

TEST #6 - PASS
I tested my new RAM 2x8GB @ 3200 - Slots A1 B1


I don't know why this test passed. This is the same as TEST #1 except it passed.
TEST #7 - PASS
I tested my old RAM 2x8GB @ 2400 - Slots A2 B2


Friends Computer

TEST #1 - PASS
I tested my friends RAM to make sure it works. Slot A1.

TEST #2 - PASS
I tested my friends RAM in the other slot (there are only two).

TEST #3 - PASS
I tested my old RAM 2x8GB @ 2400

TEST #4 - PASS
I tested my new RAM 2x8GB @ 3200



I am not sure what is going on. Any help provided is much appreciated. I can provided the minidumps from Windows if that helps.


Here are the results of the one fail.

Well there is definitely something wrong.
There are 10 bits in error which is more than for your typical RAM failure.

How similar is your friends computer. Can you swap CPUs and see if yours becomes stable?

I can swap CPUs.

I have run the two more tests and have passed with no errors:

My old RAM 2x8GB @ 2400 - Slots A2 B2
My old RAM 2x8GB @ 2400 - Slots A1 B1

Is it possible I didn't plug the RAM in correctly and as a result caused these errors? I am having difficulty reproducing the error.

I can't edit the above post (unapproved maybe?). I would like to clarify the tests were run with my CPU and they passed. I haven't swapped CPUs yet.

Maybe RAM slots were dirty or corroded, and re-seating the RAM a few times cleaned them up.
