RAM does not fit in motherboard

[LeonWBA]

Hello everyone, I just finished a thread when I thought I had solved it, however trying out the RAM by hand I find the notch in my DDR4 RAM is too far in the left for my motherboard, although it clearly states on PcPartPicker and Aria PC it does support DDR4 RAM:

Have I made a silly error with some technical details unspecified in my mind or are there other problems:

Show a pic of the ham held up to one of the ram slots.
and.. turned around.

Something is wrong, and I have never heard of ram or motherboards being mislabeled.

The link you posted to Aria PC says the board only supports DDR3. And you have DDR4..........

(Copied and pasted)
Features:-
- Supports 6th Generation Intel® Core™ Processor
- Dual Channel DDR3, 4 DIMMs<<<<<<<<<<<THIS
- 2-Way Graphics with Premium PCIe Lane

Oh I see it now he posted 2 diff boards one ddr4 one ddr3 the two different times he posted the aria link. Bought wrong board

The motherboard should have a sticker that identifies the model number. That is probably the definitive identification.

Here is the gigabyte spec for GA-Z170-HD3 which definitively says DDR4.

That is not what you received. Aria pc screwed up the description and sent you the wrong motherboard.

It does he bought ddr3 version... Stupid of gigabyte to name them the same thing

 

[Supahos]

The pic and name are the ddr3 version of the board the description is wrong, the specs are right. Still think giga should get kicked in the nuts for naming them identical things
