Intel also said the same thing about DDR3 over 1.5 and any overclocking in general.
1. As your reference says ... up to 1.35 is fine according to the official mantra ... The fact is however that while 1.50 - 1.65 was common when DDR3 1st came out, as product lines matured, this dropped lower and lower, down to 1.25v as I recall. So if you have that.. you have no worries, real or imagined to worry about 3L labeling as long as it complies w/ the 1.35 limit.

2. You should be aware that hi performance DDR4 kits (3733, 3866, 4000, 4133, 4200, 4266) are rated for > 1.35 volts. So why are they made if the 1.35v limit is inviolate ????? Why are DDR4 RAM kits listed as "certified compatible" ?
3. Lets also remember all the folks running around claiming that anything above 1.5 was going to fry your MoBo / CPU as far back as Haswell. This turned out to be false information.... Remember official support from Intel does not include overclocking and yet Intel makes K series processors... Intel didn't officially support anything above 1.5 for Haswell and yet had hundreds of "certified Intel compatible" sets of RAM on the XMP certified list of RAM kits. So how could it be so "scary scary" and be listed on Intel certified compatible lists ?
The 1.5v for Haswell / Devil's canyon was the "official" support criteria as that is the accepted standard published by JEDEC. Anything beyond 1.5v for DDr3 or 1.2v for DDR4 is associated with "overclocking"...overclocking is not part of the JEDEC standard,
4. But let's go back and what wccftech **actually** said ....
"Intel Skylake processors can be damaged by using DDR3 memory
for a prolonged period".
In other words, the same thing they say about DDR3 over 1.5v and overclocking (XMP) of any sort. The above is no more true than the following:
"Intel Haswell / Devils Canyon can be damaged by overclocking / higher voltages for a
prolonged period". Why did they have 1.7v kits on Intel's published certified compatible listings for Haswell and Devil's Canyon ? Why do they have 1.4v (an greater) kits on Intel's published certified compatible listings for Skylake ?
"Intel [Insert every Intel CPU CPU ever] can be damaged by overclocking / higher voltages for a
prolonged period".
My personal box (4770k) has been running at 4.7 Ghz OC with DDR3 @ 1.71 volts for 40 months.
My son's box (2600k) has been running at 4.8GHz at well over it's rated memory voltage since 2011
Neither apparently constitutes a "prolonged period of time". Most PC enthusiasts are aware of the breakdown of the insulating spaces between circuit races due to high voltages and / or heat. However, it does not concern most of us because by the time this breakdown occurs, we've long ago moved on to a new build.
A similar analogy might be your local race track. Even the backyard mechanic knows that engines can be damaged by pushing rpms past the redline
for a prolonged period of time. But those that do win races, those that don't lose. If you want the performance, you accept the fact that you are not going to get 250k miles outta that engine. But few need 10 years outta their CPUs.
Again, I'm am not saying that when building a new box it make any sense to grab DDR3 over DDR4. The cost of RAM is so little and adding 1 new stick to an existing stick is risky so that it's hard to justify from a cost basis.
What I am saying, is that the "scary scary" headlines are click bait designed to generate ad revenue and simply overblown. Simply put, to quote Yogi, it's "Deja Vu all over again". We been hearing the "oooh scary scary voltage" thing since Haswell but what we haven't seen is any reports of actual failures. Try and find a set of high speed (2400 - 3200) that wasn't well over the "scary scary 1.5v Haswell Limit" that the forums were full of warnings about. You are overclocking... the same rules apply that have always applied... nothing new here. Overclocking requires increased voltage and increases heat which in turn reduces component life ... and no one who overclocks apparently cares. I saw folks running DDR3 Mushkin Redline kits (Hynix modules) up to 1.94 volts ... nothing blew up.
5. Finally, here's the word direct from Intel
http://www.legitreviews.com/what-is-the-safe-voltage-range-for-ddr4-memory-overclocking_150115#T6PDO7UfPGXvRLYQ.99
Legit Reviews contacted Intel about the safe voltage range on DDR4 memory and we received this response.
“1.5v is the absolute max we allow for XMP certifications. However, good DDR4 memory will run at 1.35v up to 3200. Technically, no “safe” (guaranteed) OC over-voltage but 1.35v or lower is best.” – Intel
In short, for DDR4:
JEDEC profiles - 1.20v (JEDEC being equal to "official support")
XMP Profies < 3200 - 1.35 volts
XMP Profies > 3200 - 1.50 volts
The IMC will be in no way be affected any differently if that voltage is coming from a DDR3 or DDr4 kit.
