Do 95 chips clock higher?
There're actually 2 methods to detect TJMax on an Ivy Bridge-E processor. First one is the MSR method AIDA64 uses, and the other you can do it yourself if you want. Make a HTML report of any pages of AIDA64, scroll to the bottom of the report. Then start scrolling back until you reach the PCI device that's labelled:
Bxx D0A F00: Intel Ivy Bridge-E/EN/EP/EP 4S/EX - Power Control Unit 0 ("Bxx" could be e.g. "BFF")
Under that label, find the line that starts with "Offset 0E0". That line should look like:
Offset 0E0: FC 33 00 00 00 0A 5F 00 40 9F 5A 00 40 9F 06 00
In that line the 7th register (starting from "FC"), register index 0xE6 will indicate your CPU's TJMax temperature in hexadecimal Celsius value. If it reads 5F, then your CPU has a TJMax of 95 Celsius. If it reads 5B, your CPU has a TJMax of 91 Celsius. You can check the description of that register in the Ivy Bridge-E datasheet Volume 2 (Intel document number 329367-001) in section 6.1.8 TEMPERATURE_TARGET, bit 23:16.

Yes Fiery answered, 2 Tjmax for IB-E... 😛
