I also am having trouble setting the CPU speed in my BIOS, it
is currently setting it at 1600 instead of 1900+, any suggestions?

Yea, Leave it alone
the 1900+ runs @ 1600
PR Rated chips, gotta hate em in one way and love them in another. Intel
has bigger numbers for slower chips and can sell more.. so this is how amd
made competition..
the 1400 (non mobile) was the last non PR Athlon chip.. so a athlon 1400 is
running @ 1400, a athlon xp 1600 is running at 1400
ect ect
