[SOLVED] Ram working but not together

[FAZ98]

So I just bought a new A320 MSI and I placed my ram in it. Now this is a very weird problem Idk how to solve it. I have 2 slots. both ram working individually perfectly but when I put them together it doesn't give me display. Now I know it's the ram because I tried different sets of ram ( my friends) and it worked. What can be the issue with the rams?

What RAMs are you using? Spec?

Are you overclocking?

RAMs that work = ?

RAMs that do not work = ?

Did you purchase a set of matched RAM modules for dual channel use?

Physically numbered Page 3 (Specifications) provides supported RAM information.

The page also recommends: "* Please refer www.msi.com for more information on compatible memory. "
