Memtest86 Errors with 2 Sticks....No Errors with 1.

I have two identical sticks of memory that were purchased together (Team Xtreem LV 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DD) on a ASRock Z75 Pro3 motherboard w/ a Intel Core i7-3770 Ivy Bridge 3.4GHz processor and a CORSAIR CMPSU-450VX 450W power supply.  The main components are 3 years old, except for the power supply which is 6 years old.  This is a computer I built for my mother.  There are intermittent BSOD's and the errors listed are inconsistent.    


I ran Memtest86 and immediately got errors.  I then tested each stick separately, which resulted in no errors.  I tried the sticks in different slots, resulting in no errors when individually installed, but when I put in two (either in dual mode slots or separate (A1 and A2 or A1 and B1, etc...)) errors immediately appear.


I then disconnected all the hard drives/dvd from power and tried again.  Same results:  1 stick fine, 2 sticks errors.


I currently have only 1 stick in, to make the machine usable.  My question is, what is my next step to figure out if it is the motherboard (which is under warranty until October) or the processor or something else happening with the power supply?


The BSOD's have occurred both on Win 7 Ultimate and Win 10 (x64).  I am attaching reports from both 1 stick config and 2 stick config.  It is in a new install of Windows 10 x64.  


Any suggestions will be appreciated.  -)




-- UPDATE --


I swapped out the power supply for one that was in a stable, working computer.  I put in the 2 sticks and immediately got errors during MemTest86.  :(

Try Prime95's Blend Test (it tests mostly RAM).


The RAM has a lifetime warranty.

The motherboard warranty runs out in October.


I'd suggest contacting the motherboard manufacturer/reseller for instructions on how to RMA it.
