I don't know what my batch is. I lapped it and forgot to look. I bought it from Newegg at the end of March if thats helps. I have been able to get 3.8GHz into windows but it is not stable. I am leery of increasing the voltage any further. I cannot get 500 FSB x 7 to post. Any thoughts. Right now I am at 400 x 9 at 1.5125v (1.50v actual). In Orthos #9 my temps are ~ 65....67C.
