well we all know k5 has two revisions of core: ssa5 and 5k86, pr100 and lower are ssa5 while pr120 and higher are 5k86.
5k86 seems to have only gold-top package, and with package number 25676.
but ssa5 has both ceramic and gold-top package, ceramic has package number 25600, while gold-top is 25426, does different package number indicate any difference inside? and with heat dissipation?
