the principle thing to recall is that laptop SODIMM’s of various kinds can not be combined collectively within the equal laptop. for instance, if your pc uses DDR3 memory then there is no use looking to installation a DDR2 SODIMM in there. it is now not simply the range of pins that vary however additionally the pin layout, operating voltage, timings and addressing and so on.
Does this mean upgrading is a burden satisfactory left to professionals? Of path not!
pc SODIMM compatibility
whilst it is impossible to mix and fit SDRAM, DDR, DDR2 or DDR3 SODIMM’s (any mixture) collectively it is commonly just best to mix and fit the equal types of SODIMM’s together, although the logo of reminiscence differs. allow’s placed this into perspective. You can get more details about http://pickcheaplaptops.com/best-2-in-1-laptops-under-300/ here.
for instance, say you have got a DDR2 computer that shipped with a unmarried DDR2 SODIMM. Its ability is pretty tons beside the point however permit’s assumes its 2GB. you now need to improve to 4GB however the DDR2 laptop reminiscence improve you got is of a one-of-a-kind brand than the only presently hooked up (i.e. Samsung Vs Hynix). Will this paintings? In 99% of cases sure! you notice, the logo is for most element a non-problem, what’s applicable but is that each modules are DDR2 as a result observe the DDR2 SODIMM specification.
even though the memory timings fluctuate between the modules then this is also ideal (until you need every ounce of overall performance you can get). The only factor you should pay attention to whilst buying is the reminiscence velocity. for example, if that present day 2GB RAM is of the PC2-5300 (667MHz effective) range, you need to ensure your new DDR2 computer SODIMM is also at the least PC2-5300, in any other case the memory controller within your computer will be compelled to run both SODIMM’s at the velocity of the lesser (i.e. slower) SODIMM. To extrapolate this similarly, PC2-5300 and PC2-6400 DDR SODIMM modules will work collectively albeit at 667MHz and now not 800MHz (powerful).
