why a core i7 620 lm (2.00 ghz and with turbo boost 2.80 ghz ) has a very low bus speed @ 133 MHz as analyses with Intel processor identification tool . is there a problem with processor or it is the real speed of the bus ?
my os is windows 8.1 pro and laptop is ThinkPad x201 tablet.

Well remember you are on a tablet and that is a low power module, so to keep power down, it may be slower. Not exactly sure if that is too low, though. If your tablet is working fine, I wouldn't worry.

That's the real bus speed without factoring in the multiplier all CPU's will utilize.(different for each cpu, generation etc)

Yes, it is. I forgot that the 1st Gen i7's have such an odd multiplier.

You can't change anything on a tablet. Your final CPU speed is determined by, in your case, 133 MHz (bus speed) x 15 (multiplier) to get your final 2.0 GHz
