Testing only the turbo clock speed of an overclocked AMD FX CPU
Testing only the turbo clock speed of an overclocked AMD FX CPU
I usually stick to the temperature-to-voltage connection. When temperatures fall, electrons move less vibrationally, allowing you to safely boost their directional energy (voltage). You can add about 50 millivolts for every 10°C drop below 71.1°C or 61.1°C. My CPU is at risk since it’s above 50°C, so I’m using a safety margin here.
To stay safe, just like those Phase Change enthusiasts who run between 1.65V and 1.7V, you should use:
- Stock 1.40V for temperatures over 90°C
- 1.50V for max 71.1°C
- 1.55V for max 61.1°C (FX 9590)
- 1.60V for max 50°C
- 1.65V for max 40°C
- 1.70V for max 30°C
It’s clear that a 30°C chip at 1.7V behaves like a “burning” stock chip at 90°C. The transistors are really under strain. Heat and voltage speed up electron movement. Eventually, chips start overheating faster than LN2 can cool them, causing immediate failure. The LN2 stays on top of a nitrogen vapor layer...
So you’ll find some FX 4300 TJmax at 90°C, FX 8350 at 82°C, and even 8350 OCed at 61°C. Some say up to 50°C max. It’s like a chip that burns after just a minute under these conditions.
