Upgradation Question: Are these CAS Latencies the same?

I'm currently running an ADATA 2GB DDR2-800 module, and I'm planning to add another 2GB to this. However, I can't find the same module in the market, so I'm planning on buying a 2GB DIMM from another manufacturer. I understand (correct me if I'm wrong) that the CAS Latencies have to be same for both the DIMMs. So I ran CPU-Z, but couldn't make sense of the table of timings it shows, so here's a screenshot:

First question: What is my CAS Latency?
Second question: Is one of these compatible with my PC:

Thank you.

Go to the memory tab to see what the ram is actually running at. For any chance of compatibility you need to match ram voltage all timings and speed. Remember they aren't guaranteed to work together.

As long as your bios settings for timings voltage and speed are within specifications for both sets of ram they should work but this is not always the case.

OK, so if I were to buy 2 new DIMMs, which one of the four should I choose?
