Instead focus on your drive If you havenвЂ™t already done it going to a SSHD hybrid drive or better yet a good high speed SSD. The S is for SO-DIMM (laptop RAM), which they both are. What difference does this indicate Thanks For all intents and purposes they are similar. So donвЂ™t spend extra for the few nano seconds of improvement.Д¬onsider going with more than 8 GB of RAM I would go with 16 GB if you want better performance working on large items or running multiple apps concurrently. The second one is ВЈ20 cheaper, and is almost identical in the specs, except it says it is PC3L-12800S, rather than PC3L-12800 in the former. L: Steht fГјr 'low voltage' (niedrigen Stromverbrauch) und macht ersichtlich, dass der RAM-Riegel mit 1,35V betrieben wird (wobei die meisten Riegel mit dieser Bezeichnung auch 1,5V kompatibel sind). Alternativ stГјnde 'PC2' fГјr 'DDR2-RAM' usw. You can use the faster RAM, but, you really wonвЂ™t see a sizable difference. PC3L-12800S: PC3: Steht fГјr die dritte RAM-Generation, also 'DDR3-RAM'. Your MacBook was designed for PC3-10600 DDR3 SDRAM, its best to stick with what Apple expects. But thats only the modules ability not what the system is running its memory bus speed at. The PC3-12800 is non ECC, unbuffered and the PC3-12800U fits the same description. While the first one operates at both 1.5V and 1.35V (PC3L - here a letter 'L' stands for this and means 'low'), the second one operates only at 1.5V. This is the speed of the RAM Clearly DDR3-1600 is able to run faster than DDR-1333. unbuffered RAM) may be identified by an additional U in the designation. Answer: The most important difference between these two modules is operating voltage. will be professionally packed and shipped out via UPS to the Lower 48 States. PC3L RAM will work in a PC3 based system as it will run at the standard voltage and will inter-operate with PC3 RAM within the system.ДЎ2800 MB/s (DDR3-1600) Vs 10600 MB/s (DDR3-1333) The 03T7802 is a fully tested Lenovo 4GB PC3L-12800E DDR3 Memory Module. Buy PC3-12800 (DDR3-1600) Server RAM ECC 4 Modules and get the best deals at the.

PC3 is standard voltage (1.50V) where PC3L is low voltage (1.35V) - A system which requires PC3L cannot support PC3 RAM. Lets breakdown the different elements in the modules description:
