E6420 which batch to keep?

[Nnyan]

Hello,

Got two E6420's and I wanted to see if anyone knew which batch I should keep. I'll test them both but I figure I would see if anyone has any experience with these.

FPO/BATCH# 3714A297
FPO/BATCH# L709A537

Thanks!

Testing is the only way to know which one is best. You could have 2 cpu's from the same batch and one might overclock great and the other one not overclock at all. It's mostly luck of the draw.
