I have a Toshiba Satellite L635-3010 with 2 DDR3 slots. It came out of the box with 2 SODIMM DDR3 PC3-10600 2GB RAMs. I recently bought two DDR3 4GB PC3L-12800 modules and I want to know if its still possible to use them in my laptop. I was thinking about something like limit the frecuency of the modules using the BIOS so they can work with my motherboard. Does that make sense or should I buy other modules?
Run a PC3L-12800 on a PC3-10600 slot? Is it possible to limit ram frequency and still use them

The motherboard specification says it will take 1600 if you overclock. So yes, you can use PC3-12800, since that has a 800 mhz bus speed. The Asus BIOS should over clock it on first boot automatically.
It's been a while since I've purchased RAM; it didn't click that PC3-12800 is an 800 mhz bus with a 1600 data rate.
tl;dr = PC3-12800 is 1600 data rate.
What you are referring to is related to DDR3 memory standardization.
- DDR3 or PC3 is the Standard Voltage memory module that operates at 1.50V (JEDEC compliant)
- DDR3L or PC3L is the Low Voltage memory module that operates at 1.35V (JEDEC compliant)
- DDR3U or PC3U is the Ultra Low Voltage memory module that operates at 1.25V (still not JEDEC compliant)
Most, if not all PC3L modules can support 1.50V operation, so there shouldn't be any issues in your case
Edit. I've just checked in the Samsung catalogue, and I can confirm now that your Samsung M471B5273CH0 PC3L is dual voltage module. Enjoy :)

Toshiba Satellite L635-3010 has HM55 chipset, so it uses 1'st generation of intel processors. Intel 4th Generation processors require a new type of memory SoDIMM known as DDR3-Low Voltage or "DDR3L.
From the point of the voltage it should work. From the point of frequency there might be a problem. Intel P6000 which is standard processor in L635-3010 might not work with PC3L-12800 (this is my experience with similar laptop on HM55 chipset)
You can try put memory into slots and see if it will work properly. If there will be no blue screen and operating system will work smoothly than you can use it.
