I took advantage of having to replace a bum 3800+ to get a 4000+ from the Egg for $79 delivered. Feels really good so far. Also got to use the XP-90 that's been lying around. Very nice with the 2x120mm fans in the Rosewill case.

This isn't for me, so I'll take it to a mild O/C. How well do these CPUs do?
 
A new 4000+ 939 for $79?! I paid $45 for a used 3000+ a few weeks back... I would have definitely sprung for a 4000 at that price.

What's the stock clocks? It has to be substantially higher than mine (1.8)... take it to 3 GHz.

Probably the usual - 2.5 to 2.7 GHz on stock air.

The $79 one is OEM on Newegg.

But they start out at 2.4...??? These chips don't OC well or what? If it wasn't for my board I could do 2.5+ all day long stable. What's the deal with only a 300MHz increase? These can't hit 3.0? I'd want one... only if it would hit 3.0.

What's the most likely 939 chip that will hit 3.0 that's NOT an opteron or FX processor?
 
It also has 1 meg of L2 cache, so 2.7 would be fine for a comfortable, stable O/C. I still have a coupla 939 boards to use for upgrades, so if the 4000+ stays cheap, it'll be a nice choice even if it isn't a monster overclocker.

It's 2.4 GHz, but they come off the same wafers as the 1.8 GHz chips, that's why they both overclock to about the same speed.

Go into the OC guide and look at what people are getting with the 4000+.

Actually they don't. The 4000+ (2.4GHz) is a San Diego core and has 1MB L2 Cache. The 3000+ (1.8GHz) is a Venice core and has 512k. They use different masks to produce them so they can't be made on the same wafer.

why avoid opties and FX chips?

many of the opties can do 3ghz .. even some of the cheap 144's can

Obviously, but a lot of the San Diego 1 MB cache chips are just Opterons with disabled 2nd cores, so they could definitely have shared a wafer with a 1.8 GHz Opteron.
