You don't compare both memory for FPS, all matters to the cpu architechture, and the ram timings. DDR4 setup would be more future proof compared to DDR3.Does ddr even really matter when it comes to performance? i been seeing alot of benchmarks with being ddr3 vs ddr4 but both with the same fps? what is going on exacly?
Actually it does. 7th gen was the last gen with DDR3 support.7700 does not support DDR3. Thats incorrect.
Thats DDR3L which is dual-voltage chip and can be operated at varying voltages of a default 1.35V, all the way to 1.5V if required, unlike DDR3 and were only compatible on some of the boards on the Skylake platform and not Kabylake. Since 7700 is compatible with Skylake, only some Skylake boards could run it but was not officially supported or recommended AFAIK.Actually it does. 7th gen was the last gen with DDR3 support.
DDR3L is still a type of DDR3.Thats DDR3L which is dual-voltage chip and can be operated at varying voltages of a default 1.35V, all the way to 1.5V if required, unlike DDR3 and were only compatible on some of the boards on the Skylake platform and not Kabylake.

Thats not officially supported by Intel. Check your own Intel link above. Those boards were frankensteined by board partners later on consumer demand.DDR3L is still a type of DDR3.
Most of the DDR3 boards had support for regular DDR3(couple examples below).

It worked on Kabylake as well. Just because something is not officially supported does not mean it's incompatible/won't work.Nope, you cannot replace DDR3L with DDR3 on those example you have given, so they cant be same. And as mentioned above, it was just for the Skylake gen. and only on Z170chipset, just for compatibility reason and not even officially supported.
Thats not officially supported by Intel. Check your own Intel link above. Those boards were frankensteined by board partners later on consumer demand. Not many people adopted it and those who did were plagued with issues and I remember seeing issues all over the internet regarding this at that time.It worked on Kabylake as well. Just because something is not officially supported does not mean it's incompatible/won't work.
The claims were that using regular 1.5v DDR3 would lead to premature failure of the MC, but it turned out to be a non issue.
Intel's memory compatibility/recommendations has always been a bit on the conservative side.
Well actually... It does.7700 does not support DDR3. Thats incorrect.
DDR3L was officially supported, not DDR3. Check the official support page linked above by @bignastyid. Unofficially you can go to experimental territory with whatever you want, but thats not cup of tea of all users.Well actually... It does.
DDR3L and DDR3 is supported, depends on the motherboard. There is alot of 100 Series chipset motherboard with ddr3 compability, for example Asus B150M A D3. For 1.5v damaging the IMC? i dont think so, it depends on the vccsa and vccio iirc, just like Haswell also getting recommendation by intel to use 1.35v for both pc and mobile, yet everything's fine in 1.5v ddr3. Nehalem too, they were supposed to use ddr3 1.5v rated, but at that time people still use 1.65v ddr3 and use XMP, and it's just fine for years of use.
As per my understanding, the voltage being supplied to the DIMMs didn't affect the IMC, but the voltage on the memory controller (VCCSA, VCCIO) is the one that affect the IMC, CMIIW
My friend's pal used to do ddr3 on skylake because he bought the wrong mobo, and use it for a while until he get hands on a ddr4 b150m motherboard from gigabyte (i forgot which, it's still early at the time of skylake release).
You said they were not officially supported by intel? well there is alot of intel light notebook that still use DDR3L in skylake and kabylake, so ask them. Many skylake based processor (up to 8/9th gen) are able to use DDR3 on supported mobos. LTT have a video that use Onda D3 mobo(?) and tested it with coffee lake iirc using ddr3, and it worked, and performs ok.
