Why isn't there a RAM section in hardware?

Because RAM is pretty trivial. 

There are certain manufacturers that are good, and others that aren't.

If a stick dies, there isnt much to do with it except throw it away, and OCing RAM is pretty useless.

Not really a need.

Yeah, but what about DDR2 FBDIMMs? Timings? Latencies?

There really aren't that many people asking about those, so there isn't really a need for a dedicated forum for it.

Things like that could go into the hardware thread.
