[SOLVED] Installed new RAM but monitors stay black

[aaaTheBat]

Hi there, I've just purchased 2x16 GB RAM (3200MHz) sticks for my pc, an upgrade from my 4x4 GB RAM (2133MHz) sticks. However, after properly installing the monitors stay black. Everything else in the PC boots up fine. No POST beeping happens either.

I've tried putting the two new sticks in different slots (with and without 2 sticks of the old RAM), each time making sure they were put in with enough pressure so they actually clicked into place.

I even put all the old RAM back in and the PC booted up perfectly fine. So it can't be a problem with and cables coming unplugged or dead RAM slots.


I look forward to anyones response. Thank you.


Here are my PC Specifications as well:

MBD: Alienware Area-51 R2. Model 0xjkkd
CPU: Intel I7-5820K
GPU: Nvidia GTX-980 and RTX-3060Ti
RAM (old): Samsung M378A5143DB0-CPB 4x4GB - DDR4 2133MHz
RAM(new): Corsair Vengeance LPX 32GB 2x16GB - DDR4 3200MHz

Doesn't look like that Mobo supports 3200MHZ.

Per this website - https://www.hardware-corner.net/desktop-models/Alienware-Area-51-R2/
"The motherboard of the Alienware Area 51 R2 supports RAM speeds of up to 2667 MT/s. "

Does that mean the RAM won't work at all? or that it would just be limited to 2667MT/s?

Thank you for the help.

Did you do a clear CMOS after changing to the new RAM ?
It is possible that after that your new RAM will function at 2133 MT/S. So the same speed as the old one, but you will double the RAM size

do you have the model number for the corsair ram?

Looking at the samsung ram its only 1.2v where from what i can google the corsair ram is 1.35v


if the ram does work it should downclock it to 2666Mhz, you might have to leave the computer on for a while as it tries to do memory learning to see what timings it can run.

I don't think the voltage are different.
1.2V is at JEDEC speed and 1.35V is at max XMP speed.
As we can see here for the Corsair RAM sticks, in the Tech Specs
https://www.corsair.com/eu/en/Categ...EANCE-LPX/p/CMK32GX4M2E3200C16#tab-tech-specs

I don't think that these Corsair sticks have other XMP speeds than 3200.
The only solution would be to enter entirely manually :
speed 2666 Mhz
Latencies 16-18-18-35
And hope for the best
