Basic Question

 I ran scan of my comp & have a basic question.  Is the Ram speed listed the max or what is current at the time of the scan? I'm thinking max. Here is the Ram info,

Yes, 800.0 MHz is the maximum clock supported by your memory module.
Note, that DDR memories are usually marketed using effective speed (Double Data Rate), which is DDR3-1600 in your case.
OK, thanks. I thought that it should run at 1600MHz & had read somewhere that HP limited it to 800MHz on my Pavilion p6-2326s (Foxconn 2ADA) board.
