The store was purchased as an upgrade from 4GB RAM to 8GB RAM. The RAM was used in a typical small plastic package. This of course is the same for all the small SO-DIMM DDR3 modules, so you can also use his old bolt and pass these on / sell / store so. For memory itself: The memory has been installed in a MacBook Pro 13 "(Mid2010) The 2x4GB modules that were installed previously, came also from Samsung and were noisy product number on the modules almost identical except for variations in the amount of memory probably.. the 2x4GB modules had been installed by Apple. Since Macs generally very bitchy different RAM modules behave towards, I left after installation Memtest86 + through. As hoped, there were no errors. When using applications like Aperture 3, the double amount of memory shows immediately. Are the photos first loaded from the hard disk needs to be much rarer swapped to disk and the workflow is faster by hand. The endurance of the memory by continuously active voltage in the idle state of the MacBooks presents no problems. The device runs faster and stable in many applications or many applications running in parallel. Round for the 2010 13 "model of the MacBook Pro a good acquisition in the use of sophisticated programs and multitasking.
