Question Dell Inspiron 3593 Ram Upgrade Problem

[Emre2blue]

Hi, I've bought brand new Dell Inspiron 3593 Intel Core i5 1035G1 8GB 1TB MX230 Linux 15.6" FHD Taşınabilir Bilgisayar FHDS26F81C.
It has 8GB ram Photo : Original RAM

I have bought "Crucial 8GB 2666MHz DDR4 Ram CT8G4SFS8266" next to it. But It did not boot and run.
I've cancelled original RAM. And used only this ram on both slots. Still no boot.

Then I've bought "Kingston 8GB 2666MHz DDR4 CL19 Notebook Ram KVR26S19S8/8 Y-43106"
But It did not boot and run either. Neither with original ram, nor only kingston.
Is it a joke? Do I miss something ? It should run only one ram? Both New ram cannot be broken... There is something that I can do.. Please help. I'm wasting my money and my time.

RAM TIMING

As you may see from here. kingston ram is identical to DELL's factory RAM. But it does not help DELL to boot up.
