Prescott 3.0E E0 SL7PM - Costa Rica VS MALAY

[LiquidForce]

Greetings, citizen of Earth.

I have to choose one of these two 3.0E 478 CPUs - both have the same SL7PM stepping, one of them manufactured in Costa Rica and the other one in MALAY.
Countless hours of internet browsing have yet to yield any notable results.

People claim the Costa Rica to be better than the MALAYSIA model for overclocking, but neither an actual proof nor even a trustworthy opinion has been announced in this forum or in others concerning the specific comparison between the Prescott models, which may suggest that there is no actual difference between them at all.

If needed, I will try to acquire the exact model numbers and manufacturing ID's of both the CPUs.

Which one is the better? I believe the Costa Rica model to be the one, but I'm just a n00b so I'm here for some 1337 members to clarify this disturbing issue...
