How it doesn’t work. No boot at all?  Have you’ve tried starting with one stick?

Do you have the newest BIOS installed?

The keyboard lights up but the screen remains black. No idea about the bios

Hi Erdoc, any success with your upgrade, I am going thru the same pain with Crucial memory. Appreciate your input on this. 

Thanks

I was finally successful with Kingston KVR52S42BD3K2-64. Kingston has an online tool to check compatibility. Good luck

Hello Erdoc, 

Thanks for the response much appreciated.  I did not see the part you have mentioned, I found the following from Kingston, which one you have selected. 

Many thanks in advance for your response. 

Yes, sorry about that. I transcribed the number incorrectly. It would be the upper of the two shown, the KVR52S…

Here,s an update. After a Razer bios update I had an unresolvable black screen requiring warranty repair. Now that I finally got my machine back. After having to restore all of my software to my C drive I reinstalled the Kingston RAM and I got another black screen. Replacing the original 32 g ram resolved the problem. I have come to accept the fact that this machine cannot have a ram upgrade without potential unresolvable problems. Its a shame but Ill live with it

Hello, I've been reading your posts and I'm starting to worry about upgrading my RAM.
I would like to have your advice on having 2 32 GB Samsung memory sticks compatible with blade 18

I encounter the same issue. Still unable to upgrade.

How to fix it

Get crucials. I've encountered different problems with Kingstons, even few of them were dead on arrival.
