AMD Athlon 64 3700+ - Athlon 64 San Diego Single-Core 2.2 GHz Socket 939 Processor - ADA3700CFBOX

Pros: See thoughts

Cons: See thoughts

Overall Review: This is the E6 stepping of the San Diego.

Differences from E4 that I can tell:

Lower stock voltage, and lower max temp.

1.35v vs 1.40v
65C vs 75c

I think the jury is still out which is better, but I've seen backed up results (Koolance) up to 3.5ghz. An opti will obviously still get you getter. I believe this part is incorrectly labeled as ADA3700CFBOX, it should still be ADA3700BNBOX, but the stepping will end in CF. Per AMD's website.

Pros: Runs well at stock speeds. Stays fairly cool,and seems fairly snappy compaired to my old 2400mobile XP.

Cons: Purchased this with expectations of at least 2.8GHz,but it needed to many volts to run that high,therefore running to hott. The latest chips steppings are CCBWE,and are late 2005 chips. I was told they are the worst OC'ers for a SanDeigo chip. :(

Overall Review: I wish I would have purchased a Conroe instead of this,I just didn't want to buy new ram. O'well maybe later this year. Thanks Newegg for speedy deleivery. thumbs up.
