I have 2 sticks of ram and one of them doesn't work.
My motherboard is Asrock b75m.
I changed slots but it doesn't work.
Bios, windows, and cpu-z don't see 8gb, only 4
My ram is from kingston.
Please help.

The memory controller is integrated in the CPU, and it is not on the board
There is a direct link, between pins in the CPU socket, and contacts in the memory slots.
Try with 1 module, and test each slot, if one slot is not working, check the pins in the CPU socket, also do not overtighten the CPU cooler, this can cause the CPU and socket to bend, and cause contact problems, often this causes memory or PCIE slot problems
Yiou could try to use trhe support form
