Thats very impressive. Does the "stepping" (whatever that is) matter when it comes to overclocking? I have an Opteron 165 myself and with CPU-Z it says the stepping is 2 just like yours..in fact everything is the same (Toledo..etc). I haven't tried overclocking yet but will in a couple of weeks once I clean out my case wires, put in another fan..etc.
The "stepping" can't be seen through software. Pop off your heatsink and gently remove the thermal grease using 91% rubbing alcohol- DO NOT USE ANYTHING ELSE! This will take off the grease and evaporate very quickly so it won't cause any damage. On the chip itself, look for this line:
CCBWE 05** **MW
The first number, 05** (0550 in my case) is the year followed by the week of production. This chip is year 20
05 week
50 so 0550. The next letters **MW also have a lot to do with the overclock. When it is all said and done an overclock is about 75% stepping and 25% luck.
If you hapen to have a dual core opteron and you'd like to PM me with this line, I can tell you quite a bit about your chip and provide an estimation of your potential overclock!
CAUTION: DO NOT attempt to overclock if you don't have a good power supply, unstable rails will cause the electrical current to fluctuate. If it goes lower, you'll crash. If it goes higher, you may fry your chip. You always risk frying your components when you overclock- but a sturdy PSU is a must!

Try benching it in 3D. I don't know why people keep doing P95, when we know that often the limitations come from the memory controller and 3D content.
Noted! I'm doing some cpu burn in overnight tonight and I'll run PCMark05/3DMark05 tomorrow.

VERY nice overclock. how many fans/what brand did you use??
Right now I'm using the stock fans in the NZXT Lexa classic case with the exception of an 80mm fan I have mounted over the PWMIC. I have the case laying on its back with the door off, I have a bunch of fans and detailing stuff on the way so I'm going to wait until they arrive because I don't trust the stock fans.
The big typhoon with a careful application of Arctic Silver 5 using a plastic bag (Search the "Cases and Cooling" forum for a tutorial I wrote!) and a razor to even it out smoothly is all you need, assuming you have good intake and exhausts in your case. Good air cooling will allow you to take your chip to just around 1.6V (
IF you want to risk it) without having a heat problem.
