ddr3l ram : hyperx fury 8gb 1600mhz 1.35
ddr3 ram : hyperx fury 8gb 1600mhz 1.5
ps : m asking this question bec some random youtuber said it works only if ur processor is skylake above and i think i7 4790k is haswell right ? so can anyone with experience can provide me an answer i would grately appreciate it .

DDR3L RAM will work in both DDR3 and DDR3L slots per the specs. DDR3 will not work in a DDR3L slot. The biggest problem here is that mismatched RAM tends not to work well together, no matter the platform.
both of them are hyper x fury 8gb 1600mhz its just a diff of voltage , and ik ddr3 can run both and ddr3l cant run just but ddr3l ,but would it work on my case then ? the slots i have run ddr3 its an azrock z97 extreme 4 so i should be fine ?

It would be unethical guaranteeing they'll work together to avoid getting your hopes up. As @ex_bubblehead said, mixing ram can be problematic, even if they were the same brand.

Only way to know is try. Make sure you can return the ram if it doesn't work or is causing stability issues.
 
Trouble is they will have to run at a fixed voltage, you can’t run different voltages simultaneously. Therefore you will either be under or over volting 1 stick.

Then you have the fact mixing RAM always has a risk of issues even when same make and model but not from a matched kit.

Which, by definition, means that they are NOT the same.

Wrong. DDR3 cannot operate in a DDR3L slot as it cannot operate at the lower voltage. Per the spec DDR3L can operate at the higher voltage required by DDR3. However, as the two sticks are not from the same package they are most assuredly not guaranteed to work together. In fact I would be surprised to see them work together at all.

oki and does that affect the durability of either one of them ? or it dosent matter ?

yeah ik ik i just puted that in a bad way , my mobo is ddr3 and i have a ddr3 ram already im gonna add another one which is ddr3l so ill try to run them both at 1.35 if the ddr3l one didint work at 1.5 and let u khnow the result

1.35v ram can run at 1.5v, that's fine and is what it should be set at because your other ram most likely won't operate properly at 1.35v.
ok thank youu , so it should be overvolted automaticaly to 1.5v ust fine ? and if not ill overvolt it manualy and m good ?

My Toshiba C55 laptop came from the factory with a 2GB stick and a 4GB stick, when I upgraded to 16GB i noticed the orignal sticks were: one was 1.35volts and the other was 1.5volts, they worked fine together.
