X6 1100T Overclock concerns - Page 2

post #11 of 22
58C "Core Temp" is fine under Prime95, it's not great, but still within the 62C recommended limit and under 60C for extended periods. And your correct that this is a generous safety net to begin with. Just make sure that your actually reading "Core Temp", see my guide for more information. Good work on your overclock.

I think if you can get your temps lower you might be able to push the cpu farther too if you ever feel the need or want just for fun, possibly with the same voltage, I have seen that in my experience. Im assuming as temp goes up the internal electrical resistance rises and slows compunication down? Guessing from my basic electrical knowledge but cooler temps helped me go farther with the same voltages.

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". As 66racer stated, 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.

Thanks for the more in depth info, I enjoy the scientific POV. I think it helps me personally reading that. It makes even more sense to me why I need better cooling, that or i attack mine brutally with a lot more voltage. I enjoy balance though. I noticed when I pushing 4300mhz at a certain temp I start to fail and crash, if I increase the voltage i get to that temp faster and fail faster, its more noticeable when ambient temp is cooler, the oc is stable (1hr then I stop) at 70F ambient but when my room is at 78-80F within 15mins it fails. So once I have better cooling I can give it more voltage and make things right again, that or the resistance stays low enough where an increase isnt needed I was already at 1.515v (LLC) and didnt want to give it more. Once I switch to an all custom h2o loop I will enjoy pushing my OC again.

Your welcome!

That's very observant. 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.

Also, a note about high voltages (outside of spec). 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

Thanks, I take it someone is a computer/electrical engineer? I get what your saying though, im picturing the same side effect of bad relay tips? Or am I off on this a bit? Regardless I got the original point. Not many situations where heat is a good thing. I tend to relate a lot of overclocking and computer concepts to car concepts with tuning/upgrading. If Im talking to a car guy buddy (im the only one that has computers as a hobby too) and am explaining what overclocking is I normally say its like upping the boost and flashing the ecu in your car. Same parts but more power

Indeed all the Engineers in the house say "hey ho" *waves hand*

About the relays, pretty much the same concept, but yet different you know.

That's funny, I do custom car tuning and programming as well. The only major differences are that computer tuning evolves much faster - as do computers - and has somewhat less risk to one's life and limb. The chances of being scarred by pouring dry ice, or accidentally drinking a cup of LN2 instead of your Evian, or even getting fried by some loose electrical wire are lower than slamming yourself at 100MPH into a wall while trying to tame an uncontrollable over-tuned fuel-laden beast. Though I have cut myself on my computer just about as many times as I've busted my knuckles on cars.

You will find the lower the temps, the lower the voltage needed to run a certain speed, to a degree.

I needed 1.476v under full load @ 4.5GHZ on air, water, and DICE.

I get 4.013ghz on 1.35 idle and 1.38 on load with both air and water...so no the statement above is irrelevant. Like the other guy said better cooling helps to dissipate the heat. which we all like ..What im curios about is that iv noticed that alot more people need to run well into the 1.4 volts even as high as 1.5 through 1100t to hit 4ghz mark. I'm new to over clocking but found mine to be much easier..just upped the multiplier to 20 and left freq at 200.
