OClock newbie needs help DS3 rev 3.3

E4300
Mushkin 800 DDR2 stix
stock voltages

OK I've got it running at~

FSB 350
DRAM 525
cpuid = 2:3

cpuid further shows:
Rated FSB = 1400 (which is FSB 350 x 4, which means what??)

I'm really not sure if any of this is good or should be better?

Is the memory being underclocked unnecessarily?
is 2:3 poor? where stock = 1:2, does that mean the memory is really running
at 600? (1:2 = 800)
