It's supposed to be an unlocked processor. I believe I had set the CMOS to unlock (MSI terminology, not mine) the other 2.

I noticed that too. here's /proc/cpuinfo (for one of the cores) on my PhenomII X2 550 (black edition), not overclocked:
processor : 1 vendor_id : AuthenticAMD cpu family : 16 model : 4 model name : AMD Phenom(tm) II X2 550 Processor stepping : 2 cpu MHz : 3100.000 cache size : 512 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 apicid : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc nonstop_tsc pni cx16 popcnt lahf_lm cmp_legacy svm extapic cr8legacy abm sse4a misalignsse 3dnowprefetch osvw ibs ts ttp tm stc 100mhzsteps hwpstate [8] bogomips : 6228.99
and it shows the correct cpu MHZ. However, I note that the bogomips shown by yours is slightly higher than mine, which would correspond to the 3200 Mhz clock speed. So, I don't understand why yours shows 800 while mine shows the true rated clock speed. If yours was really underclocked by a factor of 4 (which would be the case if it were actually running at 800 Mhz) the bogomips wouldn't be what you're getting.
I wonder if it's an artifact of how the BIOS reports info to the kernel?...

All amd processors are either locked (Multiplier set) or unlocked (Black Editions , unlocked multiplier) Which means the multiplier can be raised to adjust the cpu speed. I think you are thinking the cores themselves are cut and in some mobos you can unlock some cores. Amd Phenom x2 555 is a Phenom x4 555 with two cores disabled for marketing reasons.
http://www.anandtech.com/show/2927
It's a roll of the dice to see if one of these can be unlocked to show 4 cores. Some do and some don't
In reality when the price of these units are so low you could have got your self a real quad for just over 100 bucks
Good luck Michael

As far as the speed being low the units have power saving features so when your not at load the processors will clock down. Disable all the power saving features in the Bios and you will see your speed go up to normal.
C2 features and C3 will lower voltage and speed and make sure Cool and quiet is disabled

First, please don't hijack threads. Opening a new thread is far more useful.
As for your question, your machine is most likely dynamically down-clocking the CPU in-order to reduce power usage. (In AMD's case, it's called Cool&Quiet) Once the CPU load increases, the CPU speed will increase.
Try this, open console, and type: $ while [ 1 ] ; do echo -n ; done & sleep 10s; cat /proc/cpuinfo | grep MHz ; kill %1
You should see the CPU speed increase.

ah. that explains it... I've got a Folding At Home client running on each core, so they're cranking away for all they're worth.

You'll also find that your system runs hotter and uses more electricity.
It's bad advice anyway. You don't need to disable your power saving features to demonstrate that the system works normally at its full rated speed. Add the "cpu frequency scaling monitor" to your GNOME panel and you'll have the option to set your CPU to one of its frequency steps or to select one of the available dynamic frequency settings available in the kernel. No reboot is required!
