Nitro N50-620 RAM upgrade

Helgur · August 2021

I just bought more RAM for my Nitro N50-620, it currently have the original 2x8GB Kingston DDR4-3200

I bought Corsair Vengeance LPX DDR4 3200Mhz 2x8GB

When I have installed them the computer starts but none of peripherals seems to be getting any signal.
Monitor, keyboard and mouse doesnt show anything (keyboard flashes quickly when computer is turned on but doesnt stay lit).

What am I doing wrong? thought they would work as its they are both DDR4-3200

You can try slot 1 and 2 kingston and 3 and 4 crucial...

batmalin · August 2021

It doesn`t support XMP profile, so return the Corsair and get the same one like the Kingston(same speed, timings and size). This is a classical RAM mismatch.

Helgur · September 2021

Called the store to get some other RAM that would work and they told me Kingston Fury Renegade DDR4 (KF432C16RBK2/16) would work.
But it doesnt, same issue

This is what CPU-Z gives me on the current memory:

Could you point me in the direction what RAM would work with it?

Helgur · September 2021

I guess its because the CAS Latency is 22? Thats really bad right?
Managed to find one RAM that has the same, CT2K8G4DFS832A
Or maybe I should just go for completly new RAM and discard the old?

batmalin · September 2021

No, just find RAM with same CL, Timings, speed and size.

Helgur · September 2021

Ok, this is driving me crazy
Got CT2K8G4DFS832A and get the exact same issue although to me they look the same?

batmalin · September 2021

Put the kingson in slot 1 and 3 an the crucial one in 2 and 4 and try again.

Helgur · September 2021

Same issue
I took out the Kingston and put the Crucial in slot 2 and 4
This is what im getting from CPU-Z
Looks the same to me, ecxcept that it has one more JEDEC on 1600Mhz, whatever that means?

Hum, I see no reason why it shouldn`t work, try with one kingston and one crucial

So, I tried with one crucial and one kingston.
It works. (slot 2 and 4)
Then I tried them in slot 2 and 3 and it still works.

Then I tried all 4 again, same issue. monitor, mouse and keyboard doensnt get signal.
Then I tried with 3 RAMs, and then it bluescreens every time I boot it up, although giving different error messages

batmalin · September 2021

Hum, this is very strange, reset to BIOS defaults and update it to the latest. Other than that I don`t have more clues.

batmalin · September 2021

You can try slot 1 and 2 kingston and 3 and 4 crucial...

Well on normal MBs the slots for dual channel are always 1&3 + 2&4, but seems Acer made it 1&2 + 3&4. Nevermind, the good thing is that the issue is solved.
