According to the AMD datasheet for model 8:
datasheet link
In Chapter 8,
Quoted:
"The AMD Athlon XP processor model 8 should not be subjected to conditions exceeding the absolute ratings, as such conditions can adversely affect long-term reliability or result in functional damage."
The absolute rating for Vcore = Vcc_core_dc_max + 0.5 V
Vcc_core_dc_max = Vcc_core_nominal + 0.05 V
Vcc_core_ac_max = Vcc_core_nominal + 0.15 V
Vcc_core_nominal = 1.50 V for DLT3C
Vcc_core_nominal = 1.60 V for DUT3C
Vcc_core_nominal = 1.65 V for DKT3C
E.g. 1700 DLT3C
Vcc_core_dc_max = 1.5 + 0.05 = 1.55 V
The
absolute rating for Vcore = 1.55 + 0.5 = 2.05 V
The numbers are the same for model 10 (Barton).
So for Barton,
Vcc_core_nominal = 1.65 V
Vcc_core_dc_max = 1.65 + 0.05 = 1.70 V
The
absolute rating for Vcore = 1.70 + 0.5 = 2.2 V
The above is based on my interpretation. Pls read the datasheet, and make your judgement.
