Nope wasn't that.
And it also wasn't an upgrade job fitting different voltage it two different banks.
Most of the stuff I can find is for overvolting of I7 above 1.65v causing damage from 1.5v
Upgraders: 1.35V memory is required!
This was the thread I got the biggest hint from.
Anyway you can choose to believe what you want. But check your manuals and check what memory you have if you have a laptop. If its meant to be 1.35 and you have it running at 1.5v it can do damage.
