ram voltage question

I currently have DDR3 1600 Desktop ram in my computer and it is 1.35 voltage. My manual for my motherboard says it will handle up to DDR3 2400 speed Ram. But when I was looking at the Ram in 2400 speed it seems it is all 1.65 voltage. Do they make DDR3 2400 speed Ram in 1.35 voltage, or can I install DDR3 2400 1.656 voltage RAM and be okay?
 
I wouldn't mix speed and voltage of ram. You have to increase voltage in order to run ram at higher speeds. The faster ram speed would only really help when you have onboard video. If you have a dedicated card, I really wouldn't worry about the faster ram.
 
I won't have a dedicated video card, I will have an AMD APU, so that's why I was considering the faster RAM. Is there much improvement going from 1600 DDR3 to 2400 DDR3 RAM? I would assume you get a 50% increase in RAM speed correct?
 
It will definitely help to have the faster speed ram for APU. You'll have to get all new ram, won't be able to mix speeds as all installed ram will be the speed of the slowest stick. Not sure if you'll technically get 50% percent better performance from the faster ram though.
 
Usually you could just dump the price of faster RAM into a new video card if you already have RAM.

Higher clocked RAM typically requires higher voltages, hence why you are not seeing any DDR3L kits at those frequencies. The memory controller of the APU can handle those voltages and not introduce any risk into your system.
