I've been able to get my m0 E7200 running at 3400 MHz at stock voltages, and now I've got it running at 3630 MHz with a little extra juice. I've read through http://www.tomshardware.com/forum/240001-29-howto-overclock-quads-duals-guide and http://www.tomshardware.com/forum/221745-29-core-quad-temperature-guide, which were useful; I'm planning on dropping my vcore a notch or two once orthos is running ok for 8h.

But! RealTemp is showing highs of 56C, and CoreTemp 61, and right now the ambient temperature is probably only 19C, and I'm running with an open case.

Ack!

So my big question for all you OC'ers: that temp guide suggests that real temp is the one to trust, that RealTemp/CoreTemp roughly correspond to TCase/TJunction, in that order, and that 60C is safe. Does that mean "safe to run at for extended periods of time"? Or "safe to OC to for five minutes to show off your stats online"?

I might still lap the hs, but that's a load of time and I might screw it up - plus it's got exposed heatpipes (sunbeamtech core-contact freezer, bleh). I might throw a 120mm fan on the crappy case I have before I close it up, though I don't really mind leavnig it open - actually, does leaving the case open actually pose any issues? Otherwise, this is my first OC, and I'm thinking it went pretty well, though I really had to fight with the ram to get it to operate at rated speeds, despite all kinds of sites saying it clocks to 1200, 1250 without breaking a sweat ("a sweat"=2.3v)

But yeah, any feedback would be greatly appreciated.

well obviously i know nothing about oc , but i can asure you! u need a decent airflow inside ur case
so get like 120mm fan fo sho! =) and imo close ur case! =)

Anyone with OC'ing experience able to give feedback? Like I said, my first time, so....

Oh, hey. I put my rig stats in my sig so they'd be in that post, in case they were relevant, and they didn't show up. Here's what I *had*, but which failed 2x in 5h of orthos:

E7200 @ 3630MHz (382.1 FSB, 9.5x)
DFI UT P35-T2R
OCZ reaper hpc 1150/5-5-5-15
3x250gb barracudas (raid5)
evga 8600gt
1.3 vcore | 1.34 nbcore | 2.3 vdimm


Here's what I'm trying now:

E7200(M0) @ 3438MHz (382 FSB, 9x)
1.26 vcore | 1.34 nbcore | 2.3 vdimm

Upped vcore to 1.3v, showing in cpu-z as 1.296 (it's a VID=1.225 unit), nbcore to 1.4v, VTT to 1.2v, loosened tRFC to 50, and it's stable at 3h of orthos, temps going between 54-60C, though it's cool in here right now (18C)

I've tried a whack of different FSB speeds, but damned if I can get anything above 382MHz to work. Ideally it'd be running 400MHz, 2:3 strapping it to 1200MHz for the ram, at 9.5 to hit 3800... as lots of people out there seem to get, at far lower temps, using compterable cooling (air: sunbeamtech core contact freezer, slightly better than a vanquisher 2, slightly worse than a TRUE).

Ah, well.

Still - anyone know about the CPU temps in real/coretemp, and what sustained temps are safe? Eg. if realtemp (roughly calibrated, tjmax correctly set to 95) is showing 55-60C under load, is it likely to burn the cpu out?

55-60 c load temps is about as high as you want to go for long term usage. The max temp on that chip is 74c but I wouldn't push it. If you really want the 400 mhz bus speed try lowering your multi or increasing your NB voltage. I have the same chip so feel free to ask more if needs be.
