Tomorrow I should receive my 64 GB kit from OWC for my 8 core nMP. I'm hoping to get a rebate for my current 32GB. I never ever expected that I would need this much ram, but I am processing huge satellite images ( 40 cm spatial resolution ) and am having to spend extra time fiddling around to make up for not having sufficient core space. I could actually use 128 GB but just can't afford it now. Anyone out there running 128 ?
