Compatible DDR3 1333 and DDR3L 1600?

Question

Iron

Hello everyone. I have a 4 GB DDR3 1333 MHz RAM in my laptop. There is an empty second slot, a friend offers to buy DDR3L 4GB 1600MHz. I think to take or not. I think what to do at a frequency of 1333 MHz, but it will suit me. Perhaps work at a frequency of 1333 MHz, but it’s not scary, the CL9 timing itself, what if it doesn’t work like that. Please accept me correctly, and do not offer to buy the best that is not, I myself know what is possible, but I want to hear the opinion of experts. There is an option either with or without it.
PS. The main work on Windwos 7 x64 is running games, Visual Studio, Linux virtual machine, video renderer.

Answer 1

For the first time I meet that all the answers were wrong at once!
In a nutshell:
Bet and do not worry!
Longer:
1) DDR3L is backwards compatible with DDR3, that is, all 1.35 V DDR3L sticks can be pushed into the usual "old" 1.5 V DDR3 slots (including in your case);
2) they are incompatible in a straight line - that is, if you insert old DDR3 sticks into new laptops / nettops that support DDR3L ONLY (usually now laptops support both voltages, but you need to read the datasheet / instructions for the laptop), then yes, it will not work (although , if it's fresh, even though it's DDR3, I won't be surprised if it works quietly, because it was made recently and using the same technical process as DDR3L);
3) do not listen to those who say that you need to shove sticks of the same frequency - this is all nonsense for 15 years since the advent of SPD microcircuits ("ala BIOS" on the RAM stick itself, in which all its performance characteristics are registered: frequencies with timings, serial, factory, production date, etc.) - using it, the computer itself will find the most identical mode (in your case it will be 1333) with the highest timings (if they differ at this frequency) and start.

Answer 2

Frequency is usually not a problem.
But the fact that the memory of different standards can become a problem.
DDR3 - 1.5V, DDR3L - 1.35V The
motherboard usually does not know how to give different voltages to different slots. Accordingly, either the first module will receive little power or the second one will receive a lot. They may even earn money, but the regime is abnormal and it would be better not to do so.

Answer 3

The RAM must be set to the same frequency! And you need to look at the documentation for the motherboard, what frequency is supported by the RAM. Take a RAM from a friend and check it in the "battle".

Answer 4

I think that it would be best to choose with identical parameters, and consider compatibility issues if a bar with identical parameters is not on sale. I recently had to change the bar in my laptop from 4GB to 8GB. There was a DDR3 4GB, 1333MHz, 1.5V stick in the slot. In one place they offered a DDR3 1600MHz and DDR3L 1600 bar. The sellers assured that everything would be OK, lying that the 1333MHz bar is a rare rarity and difficult to get. I got this "rare rarity" by pressing two buttons on the keyboard, entering the online store. I bought a completely new bar with identical parameters, but with the right amount of memory. Conclusions: 1) why take risks, experiment to disable the controller or something then, or just stare at a computer that didn't turn on? 2) why overpay when buying, for example, bar with a higher frequency? You just need to have patience and find a bar with identical parameters in terms of rank, voltage, frequency and pay attention to timings. I would not risk choosing a DDR3L bar instead of DDR3, because I don’t know how it will behave. Maybe it will be more economical, or maybe the computer will start to slow down, or maybe something will burn out.
Even if the seller puts the bar you bought into your computer, the car will “start up”, you still need all the memory to be determined, you need to avoid problems in the future, and even if everything is ok, everything works, it’s unpleasant to overpay for extra frequency megahertz.
