My mobo has four RAM slots - two yellow and two black. What happens if I have two equivalent modules in the yellow slots (a dual channel kit) and one module in a black slot? Does my memory run in a dual channel mode?
So here is the situation:
1. At first I put all modules - 2x1+2x2. Memtest showed errors. Tried frequencies 800MHz and 667MHz and enabled/disabled legacy USB support. Errors again. Tried changing slots in any combinations. Errors again. And sometimes PC starts but has no picture nor beep.
2. Then I put only the new 2x2 modules. Again errors and and again sometimes PC starts but has no picture nor beep. LOOL? In the Corsair site they are listed as compatible for my mainboard. Why is that?
3. When I put only one of the new modules there are no errors.
Now I am wit the old 2x1 kit.
Why it's so hard to upgrade the RAM, God damn it!
It turned out that one of the modules has been defective. I returned it and got two new modules.
Now I have 2x2GB+2x1GB=6GB. Dual channelo symmetric mode. That's colossal 6144MB operating memory!
Soon I'll putting a SSD and my PC becomes a supercomputer!
