I see a real advantage in e2180 coupled with the Abit ip35-e MB
 
10x v. 9x for the 2160.  
 
You set the FSB to 340 and the CPU voltage to 1.425v, et voila - 3.4GHz. Of course you can get ~4GHz fwith a few more tweaks and aftermarket cooling. Not bad for $89.

How about a comparison with the e4300, ect? Have you ever tried an e4300 series? If so, how did they do.?

Wow. 4Ghz on air?

mlhm5, nice overclock, but that's very high Vcore for Intel's stock cooler. Does your 2180 have L2 or M0 Stepping, and what are the CPU and Core temperatures at what ambient temperature?
 
Comp

Air cooling alone OC'ing up to 4GHz sounds unstable... or at least I would imagine the temps to be so high the processor would die within a few weeks.

if you got it to 4ghz and it did not blow up or you did not get a funny smell then you are good 2 go.   and if it's cool gratz on your awesome o/c hope it works for years to come  

 
Not quite, but it could be my mobo I have a Gigabyte GA-P35-DS3L I can barely get 3.2 at 1.5 Vcore I have all power saving off, pci-E @ 100 Memory at right voltage 2.2 aka +0.4V, timings relaxed at 5-5-5-15. I'll see if I can really get 3.4 but unlikly. I have M0 stepping.

 
Ya and @ those voltages a year later et voila no more cpu!
LoL for my mobo I could get it to 3.4 If I did put 1.55V, put I plan on using it for than a year, plus @ 3Ghz I can run it at a very acceptable 1.406V prime stable. And the real world gamer performence between 3.4 and 3, for the games I play, small. But none the less its pretty wild what this things can do for the price they sell at.

I agree bildo...I got mine to 3.2 but with a lot of volts..So I back it down to 3.0 at 1.406v also.  Very fast and same vista score as my friends much more expensive e8400 (5.7 score) (I know vista score isn't a high tech benchmark, and he can push his to 4.0 and blow me out of the water)  But for $200.00 less...I'm loving it!!!
