Wow what a nice Chip;)

Vcore????

~1.65V IIRC

Very fast pretest, about 10 minutes to get the score. So I think it can be pushed a bit higher. Survived a 4950 Pifast run.

what was the mb used?

Yes what mb are You used ? I also have G1 and it can do 4300 @ 3D @ air. Valid smth like 4500 ... not 52XX MHz

It's more the CPU - the fourth CPU on the photo made only around 4000-4050 and no higher. While the other three did over 4500 easily.

insane chip, on both FSB wall and core quality

WOW G1@5.2k on water Nice Nice
