Seems like I got lucky with my two from Batch 6.
One is running stable 500+ gh/s at 250 freq. (46c, 45c)
The other stable at 490+ gh/s at 243.75 freq. Above that this one gets one chip X'd out. (44c, 45c)
Should I consider re-applying thermal paste on these to bring temps down or consider myself lucky and leave it alone?
leave the good thing alone...if it works, it does so more or less stably.
I don't even want to try 250 that much, pretty content at 237.5, perhaps will try 243.75 later
