Have you tried with the RAM sticks in slots 3 and 4? The memtest is meant to test all RAM stick at once, then if there are errors start doing the single ones in each slot. I have 16GB, 2x8GB, which takes memtest 18 hours to do 8 passes.
This is the portion i am at now. I will let pass 4 complete and restart to move the Ram sticks into the slots you suggested.
