Oversikt over max volt og temp på amd/intel

In the midst of high overclocking P4s, I've noticed a lot of individuals stepping over the max tolerables for their CPUs.

 

The following are documented max voltages,temps etc. for Pentium 3, Pentium 4 processors and AMD Processors

 

Willamette Documentation (1.4 Ghz to 2 Ghz)

Section 2.10 - Table 5 states:

Max Voltage: 2.10 V

 

Northwood Documentation (1.6A to 3.06 GHz Plus All 800 FSB Processors)

Section 2.10 - Table 2-5 states:

Max Voltage: 1.75 V

 

Coppermine Documentation (500 Mhz to 1.13 GHz)

Section 2.9 - Table 6 states:

Max Voltage: 2.10 V

 

AMD Athlon XP 1500+ to 2100+

Section 6 - Table 1 States:

Max Voltage: 1.5 (50%) x 1.75 V = 2.625 V

 

AMD Athlon XP With 266 FSB (1700+ to 2200+)

Refer Section 6 - Table 1 and take the stock voltage of your processor and multiply by 1.5 (50%) to get max voltage.

 

AMD Athlon XP With 333 FSB (2500+ to 3000+)

Section 6.4 - Table 4 states:

Max Voltage: 1.5 x (50%) 1.65 V = 2.475 V

 

AMD Athlon XP WIth 400 FSB (3000+ to 3200+

Section 7.4 - Table 6 states:

Max Voltage: 1.5 (50%) x 1.65 V = 2.475 V

 

I hope this will save a lot of angst, money loss and wasted time to all overclockers out there. It does not matter if you have low core temperatures, the fact that the processor is receiving a higher voltage than it is capable of handling deteriorates it. Remember, just because the voltage is set at 1.65 V, it does not necessarily mean the actual voltage rating is 1.65 V (Asus boards are notorious for not obeying their set VCore). I suggest everybody who's overclocking give the documentaion a quick read.

 

Keep that voltage low

 

**Note: There is certainly more than just mere voltages that will regulate the health of your processor. AMD processors have high max voltages, but within their documentation there is also thermal power to consider.

Vel... Husk nå bare det at disse max-verdiene gjelder KUN ved adekvat kjøling (les ekstremkjøling).

 

Elektromigrasjon oppstår tidligere jo varmere prosessoren er, og når det inntreffer er det bare et spørsmål om tid før den takker for seg.
