M6500 What RAM?

Hi I'm planing to buy a M6500 with 4GB in 2 DIMMS and buy 2 more DIMMS somewhere else. And I have a few questions.



What RAM I should pick from , 1066mhz or 1333mhz?

Also what type of memory should I be looking on Ebay the 204pin or 200pin?

And the last one, which brands of memory are good?



Thank you.
