I had been running all day at 10x290 on the 1.4v +4% setting, and for the heck of it, i ramped the speed slightly to 10x295. Held in there for a round of OCCT!
I might try 10x300 on a tad more voltage and see if this core can do it! 2nd one might be a tad stronger.

I never tried Prime at anything other then 10X300 because I'm getting almost a 20°C rise to 55°C. I now have 2 CPU's with a lousy IHS interface. FX-55 is same thing... But I suspect between 2.8 and 2.9 will be it for Prime..... It's too long a test...

Yeah, thermal interfacing is a big issue with these CPU's it seems. That is why I always attempt to run the lowest possible voltage. With these newer cores, we cant just automatically go to the 1.65 ot 1.75 that you could like on bartons or even 130nm A64's. Little bit of a different game now.
As far as my temps, my house is currently sitting at around 15*C (at least that is what the thermostat says). As you can see from above, the CPU already idles at around 28*C. Thats running an XP-120 and a good 120MM fan. Then full load is at around 45*C. Thats a T-rise of over 30*C under load!
I might be able to handle the 1.4v + 10% at 3GHz during the winter when my room is rather cold, but the Trise will be too much during the summer when it is another 10*C hotter in the room.
BTW, the 2.9 and 2.95GHz runs were in the conference room at work, which is almost 10*C hotter than my room at home. I did the 3.0 and 3.05GHz runs at home. You will notice the difference in temps due to that.
2.9GHz on the +4% setting should be fine regardless of room temp.
Polygon, have you checked the actual Vcore voltage on these DFI boards? Setting 1.4v + 10% should mean 1.54v, but it always reads right at 1.5v. Seems as if the onboard monitor always reads 0.03-0.04v lower than actual. Not a big deal really, since temps are the name of the game. I just assume the temp sensor is correct...
For me, i gotta do long stability tests. Everything i normally run depends on stablity over long periods of time. Long movie encoding runs, long RTS games, etc. So when I say something is stable, its been put through some long testing But thats what I myself need for stability, most people do not stress them as hard. Which is why i consistantly have much lower overclocks than everyone else, but i have no problem trusting them to long jobs.
Slightly off subject, but can you do long runs of prime95 on the 275+MHz memory settings? Ignoring the CPU speeds for the runs (like 2.7G's or so). I never could get my ram prime95 stable past 260, but I could pass memtest86 in upwards of 350!

I did a 3-4 hour prime 1 time just recently and I think it was on the Neo4 and I think I did it at at least 300... I'll look for it.... OK, here it is. It's 3 hours at 10X285: here...
I don't have to tell you every brand of memory clocks differently...
