Using CPU-Z to get these numbers:
Core Speed -- 1600 MHz
Multiplier -- 6 x
Bus Speed -- 266 MHz
Rated FSB -- 1066 MHz
Hope that helps.
The chip is rated at 2.93 GHz (11x multiplier) so it seems that is a problem, not the FSB speed.
Is there anyway to change the multiplier with the v1.16 BIOS? I'm not sure why it would set itself so low.

OK, I forgot what was messed up.
So you are getting slighly more than half the GHz.
HP is aware of the BIOS issue, (it was reported by another forum member last year), but I highly doubt they will address it since the PC is over 5 years old.
I have copied and pasted this workaround from another post, which is the only thing I know of you can do.
"BIOS v1.16
Microcode v1.06
CrystalCPUID running at startup to force CPU to the correct speed.
Set the multiplier to 11x and create a startup shortcut with the following command line:
"C:\CrystalCPUID\CrystalCPUID.exe" /CQ /HIDE"
You won't be able to resume from standby but everything else works fine. That' s the best you can hope for with this CPU/board configuration."

Ok...so I'm still having issues with this command line thing with CrystalCPUID. I can't get it to actually go...I've put all the stuff in the command line and put it in the startup folder, but when I restart windows and check the CPU speed, it is not at the 11x multiplier speed. It's like the program is not actually starting up when the computer starts.
Is there something I'm missing?? I don't get why it the program code doesnt activate. Very frustrating.
