Mix Matching Ram

[kvnhardware]

I am wondering if I am able to mix match my ram sticks as my motherboard has 4 ram stick slots and I have 4 ram sticks one being
A 2×8 DDR3 1600 1.5v:https://www.amazon.com/gp/aw/d/B006YG9EEW?psc=1&ref=yo_pop_mb_pd_title

The other being a 2×4 DDR3 1600 1.5v https://www.amazon.com/Crucial-Ballistix-PC3-12800-BLS2K4G3D169DS3-BLS2C4G3D169DS3/dp/B00CWR3HVS/ref=as_li_ss_tl?ie=UTF8&qid=1464164914&sr=8-1&keywords=Crucial+Ballistix+Sport+XT+8GB+Kit+(4GBx2)+DDR3+1600+(PC3-12800)+UDIMM+Memory+Modules+BLS2K4G3D169DS3/BLS2C4G3D169DS3&linkCode=sl1&tag=techsource02-20&linkId=fbfd5caf72a542f7309be8116fcd1922


They are the same brand and on the sticks they both say 1600Mhz 9-9-9-24 1.5v, the only difference is that one is 2×4 and the other is 2×8 and one is made in China/From China the other is made of from U.S.(I dont think this matters though)

call it in the air, heads or tails.
the only way ANYONE can tell you if they will work together is to test them together. even sibling sticks of RAM made right after the other, serial numbers 1 apart in sequence, MAY not work together. I have had that exact situation.

grab a copy of memtest86 and test the RAM together, for three passes or overnight. if no errors or reboots congrats they are good you won the silicon lottery.

where they are made and where they are cut from the wafer makes a difference. impurities.
