DFI and x2 3800

My DFI board has insane volt selections in the bios. I have heard of horror stories of CPU death at 1.5-1.6 volts. Is this related to heat?
My load temps with 2x FAH and 1.45 v is only about 35C. What is the max this chip could do safely? I really want to see 3.0GHz....

depends on the age of the chip as to how much voltage it can take. If you follow the "death stories", you'll find they al lfit within a certain timeframe. If you check out overclocking reports, there are certain steppings that are said to be "good for phase" and others that are "good for water and air only". The ones that are good for phase can take more volts

So where is the play it safe limit? My mobile would do 1.95 all day long...
I know that would be instant death on the X2.

I've done 1.5v on mine...

1.55v is the highest I've done on any 939, which was with my 148.

I did 1.5 for a bit and it still stayed quite cool. I will see what it will do @ 1.55 tomorrow. I will hold it there.

just don't go very far over 1.6. This may induce damage to the memory controller.

I will stay away from 1.6. I heard this was the limit. I know it will stay cool enough just don't want to chance it.

Thanks guys...

According to MBM with the DFI plugin, my SLI-D is putting 1.62V through my XP 3700+ single core. It's been like that for nearly eigtheen months. My understanding is that X2s are a little more sensitive to heat, but the main issue I find with S939 (and AM2) is that increasing the voltage past a point like simply doesn't help.

But yes, it's always the temperature which kills the chip, not the voltage.

Actually, the two are tied closely together...more volts=lower heat the cpu can handle. Higher heat means less volts can be handled.

Right now it is happy at 1.4V with 9.5x285 = about 2700. I can get to do 2800 but am working on stability.
