Hello all. Well, I just purchased a GIGABYTE GA-MA770-DS3. I installed an AMD64 X2 6000 processor and installed two 4GB DDR 800 memory sticks. The problem i am having is DDR slots 1 and 2 are yellow, DDR slots 3 and 4 are red. Now everything I have read says you normally keep your memory sticks in the same color slots. When i try to put the memory in slots 1 and 2, the computer won't boot up. When i put the memory in slots 1 and 3, it shows single channel 64 bit during the boot up screen. When i go into the system hardware profile, it shows 3.25GB of memory. Is this something I need to tweak in the bios in order to enable the dual channel memory and for it to regognize the full 4GB or memory? Please help. Thanks.
