What does this mean?

I have been looking at the specs of Intel Core i7 4790k Link
But I got confused by this spec: DDR3 and DDR3L 1333/1600 at 1.5V
What does this mean?

DDR3 1600 @ 1.5v
DDR3L 1333 or 1600 @ 1.5v

DDR3L means low voltage.

the DDR3 part means it accepts DDR3 memory and not DDR2 Or DDR4.
and the DDR3L 1333/1600 @ 1.5V means it accepts DDR3 memory at speeds of 1333/1600 and uses 1.5 volts of electricity.
but knowing this you can overclock your ram, I have 8gb of DDR3 2400Mhz Ram @ 1.65V

 

[sahilsunny1994]

DDR3 1600 @ 1.5v
DDR3L 1333 or 1600 @ 1.5v

DDR3L means low voltage.

So I should buy 1600Mhz RAM?

It tells that higher RAM frequency doesn't make a big difference.

the I7 4790k can accept 1600Mhz ram but you can always go for higher, I recommend 1866Mhz Ram but you may need to overclock the ram to get the 1866mhz out of the ram.

Yeah normal DDR3-1600 or faster if your motherboard supports it. Something like DDR3-2133 is popular but to use it to its fullest potential, the memory controller has to be overclocked. It generally isn't a huge issue unless you try to overclock your CPU as well because of the additional heat generated by the memory controller.

Try to get low timings as well, perhaps something like 8-8-8-24 DDR3-1600 if you want to use stock clocks for memory.

Hahahaha sure sure... linus. ram doesn't make the "biggest" difference but there is a big difference in lower frequency ram, meaning that 1333Mhz ram will be quite abit slower than 1866Mhz ram, but 1866Mhz ram won't be much slower than 2400Mhz ram.

Use 1600 DDR3 memory that is rated for 1.5v. do NOT worry about the timing or trying to use faster memory.

Could you please explain the latency stuff like which numbers to look for higher or lower? 8-8-8-24 Why the last one is different?

No, Google it. You will learn a lot more if you just look it up.
