Undervolt DDR3 memory for Skylake CPUs Compatibility

Hi, I recently found out that DDR3 memories isn't compatible on skylake processors because of a higher voltage of it that may damage the cpu over time (Just weird they release a DDR3 motherboard for Skylake even if it is not supported and It's hard to find DDR3L memories for PC because it's only common on laptop memories). So I just applied a temporary solution by undervolting my ram from 1.5v to 1.35v on bios settings. It seems to have no problem on performance (no BSODs or lagging issues, Also tried on gaming GTA V) and same performance as before undervolting.

My problem is when I check on bios, It says the voltage of my DRAM is at 1.35v but when I boot and check using CPU-Z it says the two DRAM slots is running at 1.5v

My question is, does it really run on 1.35v since the bios says it is, Or did I missed something on settings that it makes it run at 1.5v when booted the system?

Anyways, I am gonna upgrade my motherboard to a b250 or Z170 and DDR4 rams in a couple of months, I just applied a temporary solution to prevent my cpu from wearing during that period of time. Is it good and enough as a temporary solution?

Below are the screenshots from my system:

Here's my System specs:

Processor: Intel Core I5 6400
Memory: Kingston DDR3 1600 Mhz
Motherboard: ASUS H110M-D D3
GPU: Palit Geforce GTX 1050 TI Dual OC

Hi, Thanks will try it later :) Also, is my temporary solution enough not to break my cpu?

as long as some settings do not change it "may" be fine and not cause any damage but there is a reason why they only recommend low power DDR3 ram for that CPU and the reason isn't always trying to get more money out of you

Tried hwinfo64 and doesn't seem to work on my system. Doesn't detect the ram voltage, maybe my system has no sensor/ or not supported. I guess I am gonna rely on what my bios says. Thanks :)
