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.
