Re: Some Questions regarding RAM
Hi,
First of all, it would be much relief if you can give us some info on your mobo models and brands, that would help much. 
From your explanation, your mobo can't run DDR2, definitely. The main thing is, the notch on DDR2 DIMMs is in a different position than DDR DIMMs, and the pin density is slightly higher than DDR DIMMs. DDR2 is a 240-pin module, DDR is a 184-pin module. (borrow some facts from wiki though). You couldn't even installed it then.
And you're right about CL, it is the CAS (Column Address Strobe) Latency. The clock cycle for the delay between the request and the first bit, from the wiki: The CAS Latency is the number of clock cycles that elapse from the time the request for data is sent to the actual memory location until the data is transmitted from the module.
For putting two different type of RAM which has different CAS Latency, the system would run the memory for the higher CL. But this is putting your system to an unstable state, your system could not function properly (memory fails, system hang up, boot failure attempt, can't install OS, etc etc).
