What lets you think it can use 8 gb of RAM? <snip> > Handle 0x000F, DMI type 17, 34 bytes > Memory Device > Array Handle: 0x000D > Error Information Handle: 0x0010 > Total Width: 64 bits > Data Width: 64 bits > Size: 2048 MB > Form Factor: SODIMM > Set: None > Locator: DIMM 1 > Bank Locator: CHANNEL A > Type: <OUT OF SPEC> > Type Detail: Synchronous > Speed: 1600 MHz (0.6 ns) > Manufacturer: Kingston > Serial Number: D52687B3 > Asset Tag: Asset Tag: > Part Number: TSB1600D3S11ELD/2G > > dilemma: > i have found kingston blue. i am not sure whether to purchase it. > the details of it can be found @ http://www.kingston.com/en/memory/hyperx/blu. > almost all the memory modules details contain the following info: > number of pins, synchronous, ecc or non-ecc, & voltage, steps [ for > eg. 2 gb = 2x1gb ]. > > questions: > without opening the laptop where can i find info about number of pins > & voltage capacity of my memory module ?

The laptop can only use SODIMM (see "Form Factor" in the output of dmidecode). Whether it is DDR3 is not shown, for the keyword "Type" it says "<OUT OF SPEC>". To determine this, a look at the built-in memory would help. Alternatively, the output of memtest86+ shows the memory type. > where can we find details about whether is memory ddr, ddr2 or ddr3 ? > some memory modules contain SDRAM in item details, what is the > realtionship of SDRAM with ram ? > > thank u for your patience & i am looking forward for your guidance & > knowledge. > war_dhan. > > -- Regards, Jörg-Volker. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
