Received my new 555 BE Callisto today and after installing and testing it, got it to unlock the extra cores and even did some OC'ing with it.
MB used is a MSI 790FX-GD70 with the v1.7 BIOS.
The chip itself is a CACAC 1004 BPMW purchased from Newegg.
The CPU-Z validation I submitted was rejected but I think it's because of the unlocking along with the chip being a newer stepping. However the results are still great and it did well as a quad overall.
What I like best is how little voltage it needs to hit 4.0 unlocked. Seems to be a fantastic chip. Only prob it has are temps (On air) when unlocked but we all knew that one was a given anyway.
Next step is to get it running cooler by getting it "Wet".Edited by Kryton - 3/18/10 at 6:37pm
