fail - your initial loop times would never be this low running actual clock, without properly set OS... which everyone can see from SS is not. Not to mention, latency at those timings and speed does not equate to the time shown.. tsk*tsk*
just in regards to checking VID.. BIOS displays VID register from single core - if you wanted to check for lowest VID core.. you would have to check one-by-one with others disabled. It may be useful for finding core for high valids and such.. if you had a worse chip
try disable core#0 and check VID again
