The title says it all, really. The thing is I don't have the money to buy a new RAM DIMMs.
These are:
MB: Gigabyte H110M-S2V DDR3
CPU: Intel® Core™ i5-6402P, 2.80GHz, Skylake
RAM: XMS3 — 8GB (2x4GB) DDR3 1600MHz C9 Memory Kit (CMX8GX3M2A1600C9)

Thank you in advance!

You could try, but the memory was rated for that voltage at those clocks for a reason. Chances are it would be unstable and you would need to underclock it, perhaps even significantly. Your 1600mhz kit may run at 1333mhz with 1.5v, or you might need to take it lower even, and it may not be stable at any clocks with only 1.35v.

Skylake shows significant performance improvements with faster RAM. DDR4 starts at 2133mhz and goes up to 3400mhz and beyond, so you'd be crippling your performance. I'd suggest eBay'ing your RAM and getting DDR4, as your RAM isn't appropriate even for older Haswell CPUs.

No, and you're not supposed to use them with older Broadwell, Haswell or Ivy Bridge CPUs either. Skylake is 1.35v max, while Broadwell, Haswell and Ivy Bridge (and maybe Sandy, but I'm not sure) are 1.5v max. Use higher voltage RAM at your own risk.

Could I select from the MB Bios to give less voltage to the memory and fix it that way?
