Question Memtest results unclear to me

[mazinyo]

I kept getting BSOD memory management. I checked the RAM with Memtest and ran 2 passes. Results with 2 sticks (16gb) showed 7 errors when the test finished.

I then took out 1 stick and results showed 1 error. I then changed sticks again and results showed 0 errors. ran it again and 0 errors again.

So theres probably a problem with 1 stick, but how is it that 2 sticks showed 7 errors together but when isolated, one of them showed only 1 error? Where did the other 6 errors come from?

I then checked the same stick again (the one with 1 error) and it showed no error after 4 passes! Whats going on?

Maybe its important to mention that these are 2 sticks of 1X8 and not a 2X8 set. Could this cause errors and BSOD? (its the exact same brand and model number, just didnt come as 1 set)

Hmm download cpuz and go to spd tab, they should give you an info if the sticks match at all.

i already sent 1 stick for RMA, but they both came in the same box and same model num on the box

Memory modules sold as Singles have no guarantee to work in any configuration other than as a Single module.

If using multiple singles, it would not be unusual that they have problems working together.

If they pass MemTest86 when used as Single modules, then they are not defective.

As you can see from the picture above, the stick I sent for RMA had 1 error on the first test but then 0 errors on the 2nd test.. does it count as defective? because I dont know why when together i received 6 errors.

could it be that both pass the test as singles but fail as dual and this would not be considered as defective sticks?
