Staying under 1.35 is good but really on a dual core you should need no more than 1.2-1.25 for all overclocks.

Your processor datasheet says 1.45V is the absolute maximum.

"At conditions exceeding absolute maximum and minimum ratings, neither functionality nor long-term reliability can be expected. Moreover, if a device is subjected to these conditions for any length of time then, when returned to conditions within the functional operating condition limits, it will either not function, or its reliability will be severely degraded."

"Stock" for the X48 is 1.2V ±5%.

"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."

Bottom line: 1.26V is absolutely safe. Between 1.26V-1.45V is marginal. Above 1.45V is frying voltage.
