Ages ago I bought two Intel DH67BL boards, two i5-2500 and six 4GB Kingston PC1333 sticks of RAM (all six in the same purchase and same model)
One machine was configured with two sticks of RAM (8GB)
The other machine was configured with four sticks of RAM (16GB)
Years went by and I bought 4x8GB for one machine and decided to add 2x4GB to the other one using the used modules from the other machine.
No luck. If I mix the modules (same brand, date, etc) used in one machine with the other two used in another machine, Memtest fails. If I use all four modules that composed the 16GB into the other machine, they work fine. Memtest Passes
How on earth, I can't mix the modules used in one machine with the ones used in the other?
