I have a Acer Aspire 5334 that I'm replacing the mainboard and upgrading the CPU. The mainboard in the laptop is a MB.PVS02.001, PGA 478 socket Intel. While I was browsing for a replacement and also a Intel T4500 CPU, there was another type of mainboard also for the Aspire 5334, MB.PXN02.001. However, no sellers have the actual spec sheet in full tech terms. I went to Acer Community to ask the same questions and they have specs for MB.PVS02.001 but couldn't find anything on the MB.PXN02.001. Do any of you who owns the Aspire 5334 and 5734z laptops have that information? The closest I could find is that it's a s478 socket, ddr3 memory. Or the info for MB.PXN02.001 is wrong?
