3 JEDEC timing table vs 4 (Memory)

memorymemory-timings

Here's my old memory, which was one 4gb stick.

Now I upgraded to two of these (total 8gb);

Notice the timings table are different. Obviously the new RAM timings are faster, but there's only 3 JEDEC slots, and the old one had 4 (maybe 7??).

I am trying to find a clear answer on if this is good or bad or what it means !

The SPD tells you the capabilities of each memory stick. You should look into the Memory tab to find the mode that your system board is actually running for the installed memory.

The JEDEC slots give the primary, secondary timings and voltage that a BIOS can use to automatically set the memory at given FSB speeds. With more RAM, your motherboard seems to have less options available.
