[記憶體] DDR3 和DDR3L Notebook Ram 問題

想問一下大家, 他們的分別?
如果用錯了有什麼後果?

DDR3是1.5V, DDR3L是1.35V (電壓低d, 慳電d, 冇咁熱)
有d機指定L的RAM才用得, 唔可以用標準電壓的RAM(1.5V), 有d機兩種都得。
按所用的機的支援情況買正確既RAM, 唔好買錯。

用錯左一般都係開唔到機

Kingston DDR3L could be safe for both 1.35 V and 1.5 V.
Kingston - DDR3L: Ready for Prime time
As DRAM manufacturers shrink their dies and/or increase their yields of DDR3L, they soon reach a point where the majority of their DRAM output becomes DDR3L or dual-voltage, handling 1.5V or 1.35V voltages. At that point, they just produce DDR3L DRAMs and sell it at the same price. We have just reached that point, and Kingston is about to release server memory modules with DDR3L DRAMs, making them dual-voltage; the new server modules will be noted with an “LV” suffix, but can be used in older DDR3 servers.

Crucial: 1.35v - 1.5v Dual-Voltage DDR3 memory
What is Dual-Voltage RAM?

Voltage refers to the power consumed by a module. In the past, most DDR3 memory voltage ranged from1.5 - 1.65v. More recently, dual 1.35/1.5 voltage modules came available at Crucial.com.  While the lower voltage memory has some advantages over high voltage (namely lower power consumption), your system must support it in order to realize the benefits.


Will the dual voltage 1.35V/1.5V parts work with my original memory?

If your original installed memory is 1.5V and you are adding a dual-voltage 1.35V/1.5V module to an open DIMM slot, the dual-voltage module will operate at 1.5V, not 1.35V.  In order to run at 1.35V, all installed memory modules must be dual-voltage 1.35V/1.5V and the system must support DDR3L (1.35V low voltage) to enable the module to run at 1.35V.


Which is better; 1.35V/1.5V or 1.5V?

Generally, lower voltage is optimal as it consumes less power and in turn, may generate less heat.  However, it is important to note that the overall system must support DDR3L (1.35V low voltage) to enable the module to run at 1.35V.  If the system does not support DDR3L (1.35V low voltage), the module will run at 1.5V.


Which one should I buy; 1.35V/1.5V or 1.5V?

Purchase whichever of memory your system supports, but keep in mind the dual-voltage module will run only run at 1.35V if your specific system supports that voltage, otherwise the memory will run at 1.5V.

你試過先可引用人地的野,正如專家話食品跌佐落地3秒內可食用無事一樣。
要睇乜版,
特別4代I係 用DDR3L ,但J係atom 同 叫P 系atom 可support DDR3或DDR3 L
,部份插錯會開唔到機或係行apps 不停stop error

即使支援兩種 RAM (DDR3/DDR3L) 的 CPU,兩條要同一電壓。

呢個我唔知係咩專家講,連無線學是學非都TEST過一秒都會有細菌

如果部機插條1.5V落去著到, 4代I反而唔怕, 因為Intel冇咁神心去特登整個memory controller, 所以IMC理論上應該同Desktop 一樣, 即係可食1.5V
反而Atom個IMC應該係原生設計for 1.35V
個道理就同Skylake用1.5V DDR3開到機但Intel話長期用會傷機一樣
用唔用到其實只係睇廠商點set, 不過傷唔傷IMC就睇Intel設計
