Hello, I was performing an upgrade of an older pc and the only thing is the problem with the memory.

-P7H55 -i3 550 --->i5 760(+ cooler Spartan 3 FOR HE1024)
-GTX 750ti
-4GB--->6GB RAM
-250GB ssd

The original memory installed in dual channel: kingston kvr1333d3n9k2/4g
Purchased memory: kingston kvr13n9s6/2
First I installed to ssd windows 10, then memory and after boot task manager said that I have 6GB. Then I installed processor with a heatsink and after booting I had again original 4gb and the only place where it shows me that I have 6gb's is CPU-z,everywhere else it shows just 4gb.

Sorry for my English, I'm just 15 year's old student from the Czech Republic.
