[SOLVED] Why my motherboard doesnt work with DDR3 4GB ram?

Jan 4, 2022
Hello, I have an Asrock G41M-VS3 R2.0 with a Core 2 Quad Q9400, I bought two DDR3 4GB of ram because in it's page says that 8GB is the max amount that the sistem can have

But it doesnt work, it doesn't matter if I put the ram in slot one or 2 with only one stick of ram, the pc turns on but doesn't post, I tried removing CMOS battery, also the BIOS is updated to it last version, do I need a custom Bios?

Any solution?
