can i use ddr3l ram in ddr3 slot

DDR3 and DDR3L are both available in the "DIMM" form factor. I think all that means in your case is that BOTH of them would fit into the slots on your motherboard. BUT, that doesn't mean both... DDR3L modules are backwards compatible with DDR3 by design. Manufacturers use the same integrated circuits for DDR3 and DDR3L. The highest quality ICs are tested for operating at 1.35... According to Dell's article, you won't be able to put DDR3 into DDR3L slot and get it to work because boards utilizing DDR3L expect your memory to work on 1.35V, compared to 1.5 v that DDR3 memory requires. However, it would work the other way around: DDR3L is designed to support both 1.35V and 1.5V operating voltages. Yes and no, it depends on how picky your motherboard is. Standard DDR3 is 1.5v, eco DDR3 ram runs at 1.25v to 1.35v and some will get those for OC headroom by OC the hell out of them while increasing the voltage up to 1.5v, but they're still safe, since 1.5v is the standard voltage for DDR3. Eco DDR3 should be the same as current DDR3L If the socket is ddr3l, then you can only use ddr3l modules. But if only the module is ddr3l, those also work at ddr3 1.5v, so mixing them will just run them both at 1.5v using a... Basically you can use either. DDR3L is a dual voltage capable memory DIMM, which supports operation at both 1.5V and 1.35V. DDR3L is also pin-compatible with DDR3! DDR3 is a single voltage capable memory DIMM, which supports 1.5V operation only. So, in this case the RAM will be running at 1.5 volts as your system does not offer a low voltage ... 1) Yes, it will work. 2) Yes, it will recognize and address them properly, in fact according to Acer's X552VL Specifications page, all X552VL models ship with DDR3L memory installed. If you had problems it would be trying to go the other way, a computer that has DDR3L slots is in general not compatible with standard DDR3 RAM. . #2. You might be able to get away with it depending on Lenovo's BIOS, but this will make the laptop run hotter (likely the CPU, where the memory controller is integrated) and reduce the battery life a tiny bit. You can find DDR3L easily, it is just that they are not usually listed as DDR3L, but as regular DDR3. geok : In general, the quick answer is NO. However, there are some boards that were designed to take either kind. I know of at least one that was made by Gigabyte. That said, those were all older boards that were released during the time of the industry switch from DDR2 to DDR3. Most boards made today are designed to take DDR3, although you can ... My laptop's motherboard is HM55 and runs on P6200 processor. The older RAMs operate on 1.5V and DDR3L asks only for 1.35V. DDR3L SDRAM is backwards compatible with DDR3 SDRAM. The chips themselves are identical, the DDR3L versions are simply high quality samples that meet certain performance requirements. The voltage difference between DDR3L and DDR3 can easily make the memory modules completely incompatible, but it's not an across the board guarantee. Thankfully, JEDEC standards say that DDR3L modules have to be backward compatible with the DDR3 standard, so most DDR3L modules should work fine at DDR3 voltage levels. For nyxee's question, DDR3L is different from DDR3 and DDR4 as it can work on a voltage range. The DDR3L RAM consumes lesser voltage compared to the DDR3. DDR3L is a dual voltage capable memory SoDIMM, which supports operation at both 1.5V and 1.35V.DDR3 works on 1.5v only while DDR4 consumes 1.2v only.DDR3 RAM uses a 240-pin connector, while DDR4 RAM uses a 288-pin connector.
