What's the skinny on the stepping that you want? And, how do you even really have a choice the way CPU's are sold? For instance, buy one from Newegg...what choice on stepping?
I'd just guess that the 4400+ dumbed down might be a better proc for overclocking. The watt rating is 89 for both, so no gain or loss there. But, with no experienve with AMD CPU;s I'm pretty helpless. I'm switching over from a Intel Asus P4PE 3.06GHz P4 with an X800XL to a ASUS A8N-SLI Premium with a EvGA Nvidia 7800GT card.
I'm stuck on the CPU, though. Single or dual core?
Oh, all the newer but almost out of production 939 mainboards ALL seem to have people running from one camp to the other claiming superiority and fewer problems. Granted the problems all show up over successes and are over represented for ALL the major makers, so you pick what you're used to I guess.

The Newer Stepping is always the better one. E4 and E6 are the new ones
with 0.09 nanometer technology SSE3, improved memory controller and
cooler operation, it would definetely be adviseble to go for one of
those 2. Performance wise there is no difference at all between the
steppings as long as they have the same model number.
OK, if I read into this, E6 would be the best stepping. But, I've seen it go backwards on Intel CPU's where one was a "hot" stepping and subsequent ones are toads. It takes statistics to really know, and one CPU can't do that.
Well, with enough overclock data, you can start to see a pattern on a given production run of processors. I'm going to figure that each stepping is like a "lot" of production and possibly not a design change. All you know is that the CPU will perform to advertised specs. That's the answer AMD has given.
But, you're right, someone has to go out on a limb initially to see what's what with each steppping and, by the time that's done some CPU steppings aren't available anymore.
So, no concern if you use it as sold, some concern if you want to hike up the clock some.
I have an Opteron 175 Toledo core, E6, 1megX2 cache.
Only got it up to a 10% OC, but did not keep it there, I am leary and don't want to fry anything while it is so new.
But excellent performance, 9658 3DMarks05 aint too bad.
:twisted: OK you pushed me, now I am running it at 225mhz mem x 11, but I had to raise some mem timings, CAS is now at 2.5,3,3,11,2T.
Gained like 400 pnts on 3DMark05 :wink:
Seems stable tho, been running for 12 + hrs straight.
