Max safe 1055t CPU Voltage? - Page 2

post #11 of 18
Temps are high. And that's ur core temp. Your CPU (what matters) must be around 70-72 at those volts.

Keep under 1.5v on air and CPU temps under 58, core under 42.

Guys....Max safe temp for thurbans is 62c and the max safe voltage for 24/7 is 1.55v.

It does not matter if it's air or water as long as the temps are not above ~60c. I ran my x4 965 c2 at 1.55v with max full load temps at ~58c. I saw no degradation after almost 2 years. His temps are perfectly fine.

Edit: If you're worried about temps get some better fans for your cooler and your temps will drop.

better fans are getting done over winter break, until then I'm stuck. So am I ok or not guys there are so many conflicting opinions here I don't know who to listen to...

Do you need to keep this thing at the highest possible clock for the next 3-4 years? If so, lower the voltage a bit.

Are you going to be replacing the CPU or are you going to be using it for a different less intensive purpose other than folding? Then you are perfectly fine.

It's long been a misconception that high voltage is nothing as long as heat is controlled. And I still disagree with the statement. High voltage will cause electrons to migrate (tunnel), and the CPU will physically suffer from it. It's called electro-migration, where gate material migrates from the +VDC side of the gate towards the GND side of the gate. This process will eventually kill that gate, and your CPU wink.gif

Every transistor has a thermal wattage in which it dissipates. When you have millions of transistors densely packed together, the amount of thermal wattage being dissipated starts to contribute to a factor called "transistor leakage". This increases electrical resistance - to internal pathways. This means less voltage is lost in the pathways and more voltage is available to switch the transistors, leading to higher speeds.

However, in general better cooling alone does not always equate to higher overclocks as the chip will still require a specific amount of voltage to run at set clocks. Better cooling in most cases simply allows you to run more voltage and efficiently dissipate that extra heat, which allows you to overclock higher if the chip is capable. Furthermore, the reason additional voltage helps is because it compensates for the electrical resistance and increases gate accuracy.

Also keep in mind that at a certain point transistor performance reduction due to heat exceeds the potential gains from higher voltages, so in the end you'll still want better cooling for performance despite the fact that it's stable with more voltage.

Sorry, you are wrong. The thermal limit set by AMD is 62C "Core Temp". The "Socket/CPU Temp" typically reads 7-10C higher than actual temp under load. So watch "Core Temp" under load. Read my guide for more information.

How you control the temp maters not. I have an Azza Hurrican case & a Silver Arrow & temps are VERY good.

Like mentioned above 1.55v is the "max safe limit" on air/water cooling for 24/7 use and the max save temps are 62C, but it starts to become unstable at around 55C in my experience.

I give mine 1.70v occasionally...but that's just me tongue.gif
