Sandy Bridge HFM_VID?

post #1 of 3
Thread Starter 
Long story short, I was browsing the data sheet for 2nd-Gen Core Mobile Processors (aka Sandy Bridges) and I noticed two other VID specifications; HFM_VID and LFM_VID.

HFM_VID stands for Highest Frequency Mode (as in highest turbo bin), and it is spec'd as 1.35v for all non-LV parts. Am I right in assuming there are few micro-architectural differences between the mobile and desktop parts (other than lower TDPs and frequencies)? It's even more interesting that the data sheet in question has been tagged with "2nd Generation Intel® Core™ i7 Processor, Desktops" for incoming searches...

Am I missing something really simple or could this be an indicator of Sandy Bridge's real voltage range?

The data sheet for those interested: http://www.intel.com/content/www/us/...datasheet.html Search hfm_vid or go to Table 7-5.

you should wait 24 hours before bumping your thread lol

Anyways, not so sure about this, but the vcc for processor core states 0.3-1.52.

Seems that the 1.52 is popping up everywhere and it is consistant with the other findings which suggest that the 1.52v is max for SB. Not so sure bud.
