After installing new ram, monitor no signal

[Saber]

Hello! First time posting here.

So, long story short, i wanted to get more RAM, so i bought a 16Gb stick. I have 4 slots on my computer and i already have 2 8Gb sticks (all 3 are the same speed, same company, etc). Thing is, when i plug in my new stick (i tried both remaining slots), my 2 monitors doesn't get any signal.
To open up my computer with 32Gb, i have to:
-Remove the 16Gb stick
-Start up my pc
-Close my pc
-Install the 16Gb stick
-Start up my pc

It's a bit annoying to say the least. If i close my pc after installing the 16Gb, i have to do this all over again.
Would be fanstastic if someone could help me fixing this problem. Thanks!

16Gb - 2Rx8 DDR4 UDIMM 2666MHz XMP

make sure you plugged the display into the gpu not the mobo

if the old ram had different specs, use the bios reset jumper

It is always advisable to expand your memory using the same sticks as the ones you already have. So it would be best to buy 2 more sticks of the same memory that was already installed.

Yes, that was my initial plan. But unfortunately, the link that i got recommended to buy the stick was that, and i thought it would be 2 8Gb sticks.

Im not sure what or where the gpu and the mobo are, nor how to reset the bios. After starting up my pc with the 16Gb stick inserted, the bios starts up and ask me if the change in memory was intentional.

Did you try resetting the BIOS before installing the new RAM? It sounds like it's failing to properly train the RAM and you've found a workaround, but why that works is beyond me. I'm confused as to what the difference is in having it boot up with the original RAM properly before in that it allows it to boot with the new RAM properly, but won't do so otherwise, as it should be the same.

I would have though CMOS battery might be failing maybe, but unless you're unplugging it between use or something (and the CMOS is failing) then I wouldn't think that could cause it.

Do you have a CPU-Z validation link (preferably one with just the original RAM and one with all RAM to see any potential differences) and/or links to what said RAM is?

after your first bootup with the 32 GB run right into bios first thing and restore defaults or at least take some pictures so you can post them and these guys can see what you're looking at. Maybe the ram enthusiasts will spot something off.

Installing new RAM = Reset the CMOS via jumper or button.
While most Motherboards no longer provide a jumper and 3 pin system; they still have the 2 bare pins you can "short" in order to reset the cmos. Just ensure the system is off before tripping those pins. Can easily trip the reset cmos pins with a metal screw-driver.

Then power on the system and it should have a message that the bios settings have been reverted back to defaults. Enter the BIOS and make any changes you need, apply the XMP profile for DRAM and then save & exit the BIOS to apply changes.

I would like to, but when the bios message pops up after installing the new stick, if i choose to open the bios, it just stays forever in a monitor with no signal.

You've tried this with only one monitor connected right?

No, both of my monitors are connected. They just both have no signal

I'd try with just one. Worth a shot.

That wouldn't cause a problem.
Just ensure at least one Display is connected to the Dedicated GPU card and not the Motherboard.

Again remove your RAM and try them one at a time.
So RAM #1, try this by itself and Slot#1 and so on to not just check the RAM, but check each slot.
So if RAM module #1 works in Slot#1, then this RAM and slot works fine. So try this working RAM is each slot by itself in order to ensure that each DIMM slot is working fine.

Reset the CMOS before doing so. Allowing the system to post with default DRAM settings which is on AUTO @ 2133, which is fine for a fail-safe.

Once you see what works and what doesn't.
Install what works into slots 2 and 4; not 1 and 3.
Then enter the BIOS and go to the DRAM settings and enable the proper XMP profile to apply the proper settings for your RAM based on its intended specs.

What motherboard do you have?

I have absolutely no idea what you just said 😂 I contacted Dell today, and i tried putting the different RAM sticks in the different slots with no success. At the end, they just told me that "It's because you have 2 8Gb and 1 16Gb that it doesn't work".

I tried checking out that CMOS your were talking about, but didn't find anything
