Windows 10: Understanding different memtest86 results with same memory modules

Hi,

First of all, I'm sorry in case this is not the right forum. I thought "general" was the best fit because the one with bsods requieres other information.

I've had this PC since 2012 and never had a problem.
I had 2 memory sticks same brand same speed (1333), 2gb each.

For reasons, I exchanged one stick for a 4gb stick, different brand same speed.
For 3 weeks I didn't have a problem, up until a bsod memory management showed up on Windows 10 2004 x64. That's when I decided to run memtest86.

These are my results. I'll call the slots in the mobo "A" and "B". "X" means empty slot.

*try 1-> A: 2 - B: 4 - failed (8,5hrs)

*try 2-> A: X - B: 4 - failed (8hrs)

*try 3-> A: 2 - B: X - pass (4hrs)

*try 4-> A: 4 - B: X - pass (13hrs)

*try 5-> A: X - B: 4 - failed (10hrs, 1st error 5hrs)

*try 6-> A: X - B: 2 - pass (17hrs)

*try 7-> A: 2 - B: X - pass (19hrs)

*try 8-> A: 4 - B: 2 - failed (1hr)

So... I was ready to conclude that the 4gb stick is failing but it was ok for 11 passes (13 hours). But it failed in one slot and not in the other.

Can I conclude both sticks work ok but not together?


At this point I don't know what to do with the little money I have, if the case is that the 4gb stick is ok and I can't use them together.
Buy another 2gb same brand and speed and go back to square 0.
Sell my 2gb and buy another 4gb same brand and speed and have 8gb like I'd like.
Sell both and buy one 8gb stick and be done with it.

Also, is it ok to have different cache speeds shown every time I boot memtest86?

Mobo is Gigabyte h61m-usb3-b3 for reference.

Thanks in advance for any help someone can provide me.
I attach images with the tests for reference.

Regards!

is the memory test in windows the same program as memtest86?

I dunno if it's the same or not, I personally prefer to run good ol' memtest86 in dos none-the-less. I have had memory that errored in memtest86 that didn't in Windows Vista Memory Test. Could've been a fluke though.

 

is the memory test in windows the same program as memtest86?

i was told that memtest86 is the same program that windows uses to test the memory and the some in linux to. is this true?

 

BSOD, SYSTEM_SERVICE_EXCEPTION and ATTEMPTED_EXICUTE_OF_NONEXICUTE_MEM

Please use a camera or smart phone camera to post images of all of the test results into the thread.

Initially you had reported that you were not able to use Memtest86+ version 5.01.
Troubleshooting steps were suggested and then you were able to use Memtest86+ version 5.01.

Please post into the thread each step that you made to get Memtest86+ version to work as this may be helpful to others reading the thread.

Initially you had used different software: Memtest86 and got errors when testing all of the RAM modules at one time.
Have you tested all of the RAM modules at one time using Memtest86+ version 5.01?
