Is it possible that the temp reading on these chips is lo/off? I may have read that somewhere, but I am experiencing it myself. The temp reading I get at idle on my 255 is usually 17-19c, which is below ambient.

Even at 3.7GHz with 1.425v core, my 255 system runs to a max of just 38C according to core temp .99.8 while running P95 blend. This is with a BE cooler, but still it seems ludicrously low. Can anyone shed some light?
Much research and reading leads me to believe that the temp sensors on these chips are poorly calibrated from the factory for idle readings. When temps rise, accuracy will increase. I've seen graphs explaining why this is so, but its been ages. I learned what I know and just filed it in the back of my mind.

At idle, my core temps will hover around ambient, often a few degrees below. Which I know is impossible. However, at load, temps will stabilize at reasonable readings, and shoot into the danger zone when I do stupid stuff. Like 1.6v on a stock cooler. So, I trust my temp sensors while under load.

Your BE heatsink should be more than capable of handling a 1.425 vCore, especially if your ambients are reasonable, and your overall case airflow is good. I'm on a stock Athlon heatsink, the one with no heatpipes, and its small as can be, but I still manage 3.6GHz 24/7.

I overclocked my ring and I need some advices.

http://valid.canardpc.com/show_oc.php?id=1550102

What do you think ?
What approvement can I do ? Do you think I can push the cpu a little more ? like 3.5ghz.

Even if I read a lot here and there, I'm still confuse.

Thanks in advance for your time.

Top of the morning, peeps. Been playing around with the Athlon II X2 250. Have had it for a couple of months. Still haven't touched the voltages, but it's still stable at 3.914 GHz. Been stress testing for 24hrs and this thing won't even get too hot. Around 45C at full load. Idling at 21C. On air, even. http://valid.canardpc.com/show_oc.php?id=1563605
Will change some info in my profile. The Athlon II x3 machine just got sold. Time for a new build then. Yay! Do you guys think that it's possible to reach 4.0?

Well, actually.. http://valid.canardpc.com/show_oc.php?id=1567250 This processor is confusing me. Don't think I will go any higher on air, though.

I'm curious... Is that p95 stable?

The reason I ask is because I can't get mine to be stable above 3.9ghz even with 1.5v on water cooling. I can run just over 4 stable for games, but P95 blend only lasts 5-7 mins. I've still got super low temps as the cooling is gross overkill for this low wattage chip, so I might try more volts in the near future.

It's stable for 12hrs of p95. Maybe I should go for another 12 to be really sure, but since the PSU is about to give up on me, I have to be careful. Will get a new one later today. Maybe I do a little more stressing then.
I did try to go beyond that 4,0GHz earlier but it won't boot up at all then.

Hey all, without reading all the pages in this post can someone tell me the difference between a 255 - ADX255OCGMBOX and a 255 - ADX255OCGQBOX or just to make it easy a MBOX and a QBOX ? Im putting together a folding rig and noticed there was a choice, Thanks

The difference between them is the core stepping. MBOX is C3 and QBOC is C2.
