post #4321 of 67259
So, 3902 (223*17.5) froze my PC after about an hour of stress. And the volts went up again (but only to 1.402 and not above).

Is anyone running (or has done so for a while) a PD chip on stock cooler and can provide some info on how they perform? I'm thinking maybe there's something up with my cooler too. On stock voltage and 4GHz I get up to 60C on cores and 70C on the socket. That's almost 10 degrees more than I get with the same voltage on default 3.5 GHz. Is it normal for the temps to go so much higher if there's no extra voltage involved? Thanks in advance for your answers, I'm really at a loss here...

I don't have hard numbers to show, but that doesn't match what I've seen. I get better results with a FSB change than I do from a multiplier-only change. I'm currently running 285x16.5 and getting much better results than from just upping the multipliers (and I've played around with RAM, CPU/NB and HT, not just the CPU multiplier).

I don't know if it makes a difference, but I have pretty fast RAM -- supposed to be 2400, though I'm currently running it at just below 2300. Maybe it's more of a noticeable difference with faster RAM??? Or maybe some combinations just tend to work better than others, even though it looks like speeds should be about the same?

Every test I've come across has a 140W difference between idle and CPU load. That does not account for idle usage. You're still looking at 170W full CPU load stock for just the CPU.

If you feel like only the CPU is drawing more power at load you can try explaining to yourself why NB temp is rising at load? And this is only the most obvious thing. It is not only the CPU that is drawing more power at a CPU stress test and the CPU alone is not drawing more then 140W at load (stock). I really don't feel like geting dragged any further into the subject as I don't think these things would be immediately obvious to people that didnt study electronics, so take my word for it or dont.

*shrug* The simple thing is, you need to prove it, not me. I have several review site's numbers on my side, the only one making claims with no proof is you.

Power consumption (heat) should go up linearly with frequency if voltage is held constant. It's just not as big a change as you get when voltage is increased -- then power goes up much more (I want to say power consumption goes up proportionally to the cube of voltage, but is that right?).

ram has been shown to increase the performance.. that is why you are seeing the difference. and that you probably are running it at tighter timings adds to it.

I never said anything on those sites is wrong, I agree with everything written there, but the question was how much pwoer the cpu draws alone, with stock settings, and I answered exacly that. There is very simple proof, the TDP given from AMD, which is 125W, this is as close as you can get to a real value since it's not easily measurable.

The proof you offer is no proof aswell tho, it is systems power consumption, not the cpus.

Lets end this discussion now, it's fruitless, let people enjoy their OCing rather.

Cool down the MOSFET-s. An 80mm fan should be enough.

x2 on this. I did a small upgrade (or rather a simple architecture change) from 8 GB Vengeances to 8 GB Dominators and my overclocks seem to run smoother.

It's really just about finding the parts that make your system flow as a whole.

Ashe! Where are those numbers rolleyes.gif

As a friendly reminder for those who have not yet posted their oc's and settings used, please visit: http://www.overclock.net/t/1331219/fx-83xx-data-collection-thread

If you could, it would be much appreciated as we are using this data to graph out multiple facets of what these chips can do at what settings in which batch or on what board, as well as trying to make use of it as a "base" settings list showing what people used to get what so that future owners and new owners have a list of working examples to go by.

Thank You. ;p

*(Thanks to those who have already posted too. thumb.gif)

the way this is set up to could also be used to post for steam roller and previouse bulldozer.. really this data could go far with tracking the progression and overclockability for these chips
