CPU: AMD A8-6600K APU with Radeon HD Graphics
Motherboard: GA-F2A78M-HD2
Ram: Corsair 2048MBytes, Part Number: CM3X2G1600C8D
SSD/HDD: ST1000DM 003-1ER162 SATA
GPU: Radeon RX 460 4GB
PSU: ATX-500B
Chassis: Vanquish
OS: Windows 7 Home Premium

Only have 2 RAM slots, But the ram says 3x2GB, I dont know if that matters
Can anyone help me?

List your specs like so:

Ram:
SSD/HDD:
GPU:
PSU:
Chassis:

All three sticks are identical? You should be running the ram in dual channel meaning 2x2GB and not 3x2GB, it's unbalanced on your system

Also are you on the latest BIOS update for your motherboard?

I think i am on the latest bios version.
I think the ram actually is 2GB, checked on CPU-Z, Im sorry.

CM3X2G1600C8D is a part number for a 3 x 2GB kit.
DDR3 1600 (PC3 12800)
Timing 8-8-8-24
DRAM Voltage 1.65V

Default DRAM voltage is less than 1.65v which likely will cause problems if left at default settings.
SPD Speed 1333MHz
SPD Voltage 1.5V

The A8-6600K supports 1866MHz memory without overclocking.
