Voltage compatibility for memory upgrade?

Looking to upgrade my laptop ram and seen some modules on eBay that might do the trick however they have different voltage to the one my laptop was shipped which was 1.5 volts. Is there a way I can find out what memory voltages my laptop can support?

I have seen this ram module in eBay but doing a search revealed that it's voltage 1.35v

My laptop is Toshiba Satellite S50D-A-00G if anyone could give me insight as to wether this ram would / should be compatible with my laptop with regard to voltage, timings, etc id be very grateful, many thanks!

 

The 1.35V modules should work. If you look at the datasheet for those modules, on page 12, it explains how the RAM works at both DDR3L (1.35V) operation and DDR3 (1.5V) operation. Also, page 11 shows the absolute max DC voltage ratings.

Crucial.com compatible RAM for your laptop. Note that all the suggested modules are 1.35V.

Thanks for taking the time to reoly with in-depth answer I did stumbled on the crucial auto identify tool and saw compatible memory. I wish Toshiba themselves makers of my laptop provided this information, there is nothing from them, not as easily as I could see anyways...

 

Basically all you need to know is that DDR3L RAM is dual voltage (1.35V and 1.5V). DDR3 RAM only works in 1.5V mode, therefore it will not work in some newer boards.

Ok I have another issue, I currently have one module that it's DDR3 and I am looking at buying a module that I seen that is DDR3L. Will the DDR3L play nicely and work with the DDR3 memory module?

And also how important are the timings? My current memory module (the DDR3 one) says 11-11-F3 and the ebay memory module (the DDR3L one) says 11-13-F3. Will the motherboard adapt and compromise making them work with each other or do different memory timings cause critical catastrophic problems? Thanks

 

Simply buy two of the same SoDimm's and sell what you currently have (after testing your new sticks for 24 hours or more...).

While many combinations of M/B, BIOS and RAM modules may work together (at least it may seem so initially), not all will.

Save yourself potential headaches and buy matched RAM modules instead (and yeah; 2x 'kits' are better than otherwise identical SoDimm's too).

 

You're right, searching other responses on Google brings the same answer.... Found two identical memory sticks on EBay, problem solved thanks!
