Dual Channel Memory won't work

[joaovittorsc53]

Hi, I have two RAM Sticks bought as a kit. Both of them work separately in both of the Slots, but when I put them together, the system won't get past the POST screen and just keeps reooting.
The only way I could get it to boot is by disabling the Memory Remap feature in the BIOS, but then only 3,45GB is usable by the OS. Doing day to day stuff and trying to game with only 4GB is dreadful, can someone please help me?

System specs:
i3 540 @ 3,1GHz;
4GB DDR3 @ 1600MHz (Should be 8);
ECS H55H-M V1.1 MoBo.

If the two sticks are a mis-matched set, that may be your issue. Dual channel memory (especially on earlier Core CPUs and boards) is sensitive to un-matched pairs. That's why dual channel memory is always sold in matched pairs.
