Faulty RAM slot

[mallowe]

Hello techspot!

I own a ASUS ROG G551JM laptop, it’s old but it gets the job done.
I have bought today a 8GB RAM stick to give it a boost.
I have made sure it is the same make, model, voltage, frequency as the one I already have.They even have the same serial number on them.

So here is the problem...the laptop won’t boot with the 2nd RAM slot occupied.With either stick.It turns on, fan starts, but screen stays black.

I tried the new stick in the 1st slot and it works perfectly.

I saw a YouTube tutorial about how I should wiggle it in the slot, In order to make it sit right, because if the slot was never used it may need this - this video:

It did nothing.

I then made a bootable usb with windows and tried to boot from that...no luck.

I then updated BIOS to the latest version...still nothing.

Now I do not know what to do.

I need advice, I was thinking about this:
Take the CMOS battery out and put it back in:
I am willing to try to do this if you think it will do anything... I am not keen on fiddling inside the laptop, but oh well.

Thank you!

The ram are both samsung ddr3l, 1600mhz.this was the one that came with the laptop and I bought another one just the same.

Check system manual for the QVL (qualified vendor list) for RAM and for any limitation or restriction on expanding RAM. Some systems are quirky (I had one system which would run 2 4GB sticks and, alternatively 1 8GB, but not 2 8GB). In some cases a small adjustment to timing or voltage in the BIOS might make it work.
