DO NOT run over 1.4v with the E8400, you will destroy it.
Both statements are very unaccurate.
It would be better to have said "majority" of e8400 can reach 4GHz with a bump in actual vCore not exceeding ~1.35v (however BIOS vCore depends on vdroop/vdrop of the motherboard) and dependant on the chip batch.
Running over 1.4v in vCore will not destroy your chip (but obviously will in many years as it does with any chip that is overclocked). However the point is moot since very little have the need to exceed 1.4 vCore unless they were very heavy PC enthusiast going for a benchmark goal.
If you are interested though, here is the thread that shows why degredation myth has been busted.
