I got my motherboard with dual channel and 2x2GB in there.
Now I tried to stick 2x4GB with the same qualities as the 2x2GB in the 2 free slots.
But now the systeem won't boot.
If I replace the 2x2GB with the 2x4 it works fine.
Is there something I should know to get this working?
Should all 4 rams be exactly the same or something?
Does your motherboard supports 4GB memory modules?
Usually the advice given is to buy memory in kits as to avoid compatibility problems between different ram vendors and sizes. There is no guarantee a mixture will work together.
If your motherboard does support 4GB, you can try swapping memory in different places and see how it reacts. You may need to clear cmos so the bios can readjust.
Yes, my motherboard does support 4GB memory since with x4B in it, it works just fine.
It could indeed be a compatibility problem since 2 are Kingston and 2 are OCZ.
Is there any way I can be sure this is the cause?
