Just curious Vivi,

 

How many cpu's did you test by now and how many actually were good?

 

and by good I mean 6.3 GHz+ for at least 2D but better for 3C classic benches

 

I tested many L310B488, i got about 4 x 6.3ghz cpu's out of about 9 because that batch is just so good.

 

costa rica's i have tested about 7 - 8 and this one was just lucky.

 

overall tested about 40 cpu's probly from various batches, and found + - 10 ok cpu's and 3 very good ones

Guess you are more lucky than I am.

 

3318B897: 4.6GHz @ 1.3v boots to windows

3334C023: 4.5GHz @ 1.3v boots to windows

 

Not so lucky yet with costa Rica.

 

Two earlier 4.9GHz air chips I had turned out to only be able to bench superpi 1m @ 5.9GHz @ -120 both.
