ekoostik :
Look at the intel spec sheet again. Table 7-6 shows that for "Processor I/O supply voltage for DDR3" the Min is 1.425V, Typ = 1.5, and Max is 1.575. However go back to Table 7-4 and you'll see the "Absolute Max" is 1.65V. (pages 68 and 67, respectively) http://download.intel.com/design/processor/datashts/322164.pdf
Thanks for pointing that out.
I am a crap reader to be honest.
I did notice though the following statement:
Absolute Maximum and Minimum Ratings
Table 7-4 specifies absolute maximum and minimum ratings. At conditions outside
functional operation condition limits, but within absolute maximum and minimum
ratings, neither functionality nor long-term reliability can be expected. If a device is
returned to conditions within functional operation limits after having been subjected to
conditions outside these limits (but within the absolute maximum and minimum
ratings) the device may be functional, but with its lifetime degraded depending on
exposure to conditions exceeding the functional operation condition limits.
To be honest I think Intel are just covering all bases but to me the short of it is, go over 1.575v and who knows what will happen and if the who knows happens your on you own!
