I've been researching these new 0312 from newegg from the OC of most people who just got them. After reading numerous posts on their results I pretty much got the OC picture. On average these will do (12x166 ~ 2Ghz) on default vcore of 1.6V. They should do fine approaching towards 2.1Ghz (given a +.5 vcore or not). But the odds of hitting 2.2 Ghz are not so good. Lots of users needed high vcores to get 2.2 ghz (1.75V +) while a few got 2.2 ghz at lower vcores. So these are much better than T-bred A's, but not as good as DLT3C. Basically for $43 u get a 2.1 ghz processor =D, good deal.
