Default e2180 Max's @2.8Ghz - Major let down

So I just picked up an e2180 and dropped it in to my P5K. (previously running an e2140 @ 2.6) I have to say I'm really disappointed with it's performance. The highest I can get it to go is 2.8Ghz running 10x280. If I move it to a 10x333, it won't even post. If I drop it to 10x300, I can get in to Windows, but it blue screens right away. I've tried vCore up to 1.425 for the 10x300 with no luck. Next I tried 9x333... @1.3825 I could get it to run Prime95 for about 2 minutes before it flat out reboots. Did I get a dud? Or is 2.8 the most I can expect from this? And now that I look around more, I'm hearing the e2160 is the way to go for O/C'ing. Is that true?
(Temps never broke 57C per core max in all my tests, so not an overheating issue)

Is your RAM set to 1:1 or as slow as your board allows?
Can you strap your NB to a faster FSB settings (this will relax some timings to allow better high frequency operation)?
If you drop your multiplier way down what is your max FSB freq? Try establishing this seperately from your CPU max overclock.
I could run my 2160 up to 3.46 prime stable, I kept the multiplier at the max and ramped the FSB 10-20Mhz at a time.

It could be an FSB hole. Try setting it to 8x375 and see if it's stable.

I tried this (8x360) to see what would happen and it's a no go. Moved it down a bit at a time to 333 before ir ran for a while, then crashed. I'm thinking it must be a FSB limitation.

@superj
Everything I'm reading now shows the 2160's as much better O/C'ers than the 2180's. As stated above, the FSB limitation is around 333; but not stable. I'm gonna have to get me a 2160 and see if I have more luck.

Or... and e5xx? Much better clockers IMHO. Mine (although it was a nice one) hit 4Ghz on air (e5200).

Yeah, that would be a much better choice.

2.8GHz is pretty sad though; even my E2140 can do ~3GHz pretty easily and it could probably go even higher if I bothered to update the BIOS on my Foxconn board.

I feel your pain, my E7200 cannot handle over 3.0Ghz with any stability.

Hmmm... e5200 you say? They're on for $69. Maybe I should be looking in that direction... Are they hit or miss for O/C'ing? Or do they have a pretty solid rep for getting to at least the 3.5 mark?

They're pretty solid from what I've heard.

MAYBE it could be the lack of VTT, PLL, Load line calibration settings.
