Aren't you the same person that said GPU's are primitive because their clock speed was lower than CPU clocks? It sounds like you get all of your knowledge from reading consumer reports and the back of popular science.
How do you recon that a processor can reach 5 GHz based on your motherboard? Generally, speed limitations on a processor are due to processor design (i.e. heat), not MB design. And why would one memory chip be 2.25 GB? Memory is incremented in amounts 2^n. You can have a 2^10 MB chip (1 GB), 2^11 chip (2 GB) Please give me an integer,n, such that 2^n = 2.25 GB.
Why would using pins directly for memory make it faster? Would you have one pin for each transistor in the memory module? How many pins do you want?
What you said is akin to me saying this:
Here is my idea for a new motherboard design. It can have between 1 and 4 processors. The memory will be installed directly onto the processor and will have the same clock speed of the processor, which can reach an arbitrarily-thrown-out-there-number of 10 GHz. Also, the memory can come in sizes of 3.4145 GB. There will also be a direct connection between all components on the board and the processor. There will be no bottleneck because everything will be gold. Also, there will be a port on the front of the motherboard that will come up with inane ideas for me so I don't have to waste my time thinking of stupid posts.
I don't mean to start a flamewar, but this is hardly highly technical because you have no basis for your idea. You said it yourself.
