Phenom II Degradation Question

post #1 of 12
Thread Starter 
At what voltage do Phenom II's start to degrade if they are kept below max safe temps?

Degradation typically occurs over 61 C for a period of 6-8 hours. If it hits that temperature momentarily it won't cause much harm. I'd say above 1.5v you'd see degradation as well.

I dunno..but there's no reason to run a chip like that hot...I ran a 965 BE for close to 9 mos straight on 1.58 vcore
max temps were 58c.
IMO..Those are some of the toughest chips there are

Unfortunately, there's no one answer for that. It's a function of the quality of the chip, its power draw, and its runtime. Even at stock voltages, the processors are degrading every time you use it. Based on AMD's warranty, AMD believes that your processor should last about 3 years. Everything else is extra.

1.55V is the safe max 24/7 for the Phenom II as long as you can keep the tempatures under control.

Iv'e accidently put 2.0V into my 1055T, only for 5 seconds, and still works to this very day, even at 4.2GHz smile.gif

Schmuckley is legendary, so I'd take his word.

Put that chip under water and crank up the volts. Voltage will still cause degradation, but heat is the biggest killer of them all.

I've had some problems with degradation. Keep the temps low and you should be fine. 90% of my degradation is due to temps.

Off course you gonna degrade with time, but its not gonna happend in 1 week or month, my phenom II X4 965 degrade from 3960 to 3850 ( stable on same vcore) during the last 2 year, that cpu was watercooled and at 1.52V never reach higher than 53 Celcius. For me its look like a normal degradation, nothing to worry about if you keep your temps under control the cpu will last.

Not necessarily. I had my 955 stable @ 3700ghz and 1.475 volts (less under load) and 3200 @ 1.298 volts. Then all of a sudden, two weeks later, overnight, It became unstable to where it would crash @ idle with 3200 and 1.3 volts, and would crash in a min of bf3 with 3700 and 1.475 volts. I now have to run it @ 3200 and 1.325 volts.
