Unforutnatly I dont think those figures work for a Mobile Barton...unless you have corrected for that already.
On that note... where did you find that info from hitechjb1?
To calculate the max absolute voltage, first I obtained some raw numbers from the AMD tech doc for model 8 (Tbred) and 10 (Barton), then have to do some calculation based on these raw numbers, ... The details are shown in the posts from the links on max voltage ....
For mobile Barton which the model 8 and 10 tech doc do not cover, but since mobile Barton is a derivative from Tbread B + Barton, so its max absolute voltage should resemble that of Tbred B 1700+ DLT3C.
But anyway, one should NOT take the max absolute voltage as so rigid, black and white, under which is completely OK and above which is completely forbidden. One should NOT base a computer design or overclocking on the "absoulte max voltage" number.
Every CPU/chip is different, even the a large sample of them follow certain (normal) distribution. Even at stock voltage, there can be a very small failure rate.
The inverse relationship between frequency and temperature will
naturally determine the max voltage and frequency for a given CPU and cooling setup. If overclocking is done properly, such voltage and temperature should be below the max absolute temperature and voltage of a given CPU specifcation (at least true for Tbred/Barton).
From the posts (listed below) on voltage that I wrote, regardless whether it is totally agreed upon, at least we should see and appreciate that there are many aspect of voltage (whether it is operated under stock, most effective, diminishing return, max regime, ...), and voltage, temperature, frequency, stability, ... in overclocking/computer design as a complex, multiple dimensional process. Especially at 20%, 30% above rated specification, there is NO simple, sinlge number of voltage, temperature, ... that can fit all situation.
