Is safe to increase voltage and ram clock when running 2 different sticks in dual channel ?

Hello I am running 2x 8GB sticks. Corsair vengeance 1600mhz cl10 and Zeppelin 1333mhz cl9. I would like to up the voltage to something like 1.53-54Vmaximum from 1.5V and make them run at 1866mhz. Do you think I could destroy something while trying that ? Thanks
 
Solution
1.65V is max safe voltage for DDR3. You should not exceed that.
1.54V is fine.

BTW - with 6th and 7th gen Intel cpus on motherboards that use DDR3/DDR3L, you should not run ram voltage higher than 1.35V.

Ok so the fact that both sticks are different does not mean anything regarding safety ? thank you

I wouldn't do that. They print those speed ratings on ram for a reason, because they are tested stable at those speeds.

Not only that the timings of both rams are significantly different, you are lucky they even run together. Theres no chance in hell you will get that stable at 1866. Won't break anything probably but you will be wasting your time at a minimum.

I'll try it now at 1.54v and 1800mhz. The BF5 alpha is really demanding so I'll try it there if it's stable. Also I'll run a memtest first if it's good for something. I don't trust it either that it will be stable.

Yes memtest86 if you're going to do it. And you should let it run for an extended term (like 6 hours at least) to be sure its actually stable. Some people run it for 24 hours.

Ok reporting back, so far everything stable and my ingame performance increased quite a lot in BF5 and BF1.
