Mixing two specific RAM

[Mauro Jurada]

Hello, I would greatly appreciate if you could confirm that my http://www.kingston.com/datasheets/kvr1333d3n9_4g.pdf
AND another http://www.kingston.com/datasheets/kvr13n9s8_4.pdf
can match and work together perfectly in dual channel.
Thank you

There are no guarantees when mixing DRAM - simply put, they might play together and they might not. Always best to buy the full amount of DRAM you want in a single package

Thanks for the reply.
there is no way to be sure about this models? They are almost identical. All except a timing for refresh. But the manufacturer, latency and other timings are the same.

Even with the same exact model of DRAM, mixing two sets has no guarantee of working
