Did I see that right when they said 1.25V on the NB for the 6 GHz OC? That is ridiculous. What kinds of FSB are those boards capable of running?

reasonable voltage for AMD is different then reasonable voltage for intel. yes, they are different chips. the stock amd volt is 1.35, so 1.5 is not that insanely high (.15+ on the volts, or a 9% increase). i wouldnt care what brand i liked more, if i had the chance to have a near unlimited supply of LN2, a choice of 5 new chips that havnt reached retail yet yes i would definitely do it.

the best way to see how much voltage actually affects the system is to get a wattage analyst type thing and install it to see how much power it really takes in. till then, just please accept that new AMD chips volt differently then intel. intel has been the overclocking king, but now amd gets another shot and they use a different method...

He said NB, not CPU... Unless that's a response to me?

But I agree the CLOCK is good on LN2. Anything else and we'll wait till the consumer reviews start popping up.

yea i didnt see the nb post actually

anyway, this is useless arguing until the actual product comes out. till then, ill be quiet (sorry everyone)

You don't know what you're talking about in so many ways. For one thing, it was more than a few seconds. It was two iterations of the Crysis time demo, as has been pointed out multiple times to people who post before watching. For another thing, the damage overvoltage causes to a processor has very little to do with overall core temperature and very much to do with power leakage. How many times have you actually seen a burnt-out processor? that's not easy. When you overvolt a processor, the electrical properties of the components are being subject to voltages higher than they're supposed to. Sure, the temperature goes up, but power leakage is the biggest threat and it's what causes errors. Overvolting a processor usually produces parity error and the like because of power leakage. Usually to a point where the computer won't even get to the BIOS. Smaller fabrication processes generally produce more power leakage because the parts are so much closer together.

You're correct in the obvious point that 1.9V is too much for any processor being used in the real world. My point I think was pretty clear: the Ci7 can't do 6GHz. It can't do 1.9V at all, let alone for a benchmark run-through. Assuming the Ci7 and Phenom II perform similarly clock-for-clock, this means good things for Phenom II.

Also, they did air overclocks. They got to about 4GHz.

They ran the Crysis time demo twice. As well as it surviving the process of clocking up there with new settings. Thats the entire time to boot up, shut down, run Crysis time demo twice, repeat. All the way to 6.3GHZ. The video showed them testing on 6.0, 6.2, and 6.3. So that chip had to survive all of this. It by no means was only going to last seconds. I'm not saying it will survive there indefinitely. But i'm pointing out AMD chips are made to take a whole lot more of a beating.

Let's not get technical, a few minutes doesn't mean I can't measure it in seconds. Put it this way, it's won't last the 10 years it would at stock It's ok if it can take a beating, but we don't want to beat our chips, we want to OC them.

Who cares? Nothing useful can be done @ that speed. i7 is still faster clock-for-clock than Phenom II.

Any time you raise your voltage your lowering your chips life by some amount.
