usually as said no ram detected... usually that says board is still functional .. closing the clips wont harm anything that I ever heard off ... remove the ram and reseat them, they will go in and click with a bit of force make sure they go in proper way as they only go one way , you can also try just 1 stick then the other stick on its own to see of it boots... you can try booting with the cd drive disconnected and side panel off it wont cause any issue for testing purposes..

r/Alienware on Reddit: X51 beeping on boot up
June 23, 2020 -
Hello everyone, I’ve been having some troubles with my really old PC. I got the X 51 from my sister who got it from one of her work buddies at a hospital. When I got it about seven years ago I don’t really know what to do with it so It just stayed on my desk. Now that I know more about computers I’m trying to get it working again, but after installing some new windows updates my PC turned off and now upon boot up it has a beeping noise. I tried switching out the ram but that didn’t work. Do you guys have any suggestions to what am It might be ?

It will beep in a pattern. Say 4 beeps then pause, or 6 beeps. The beep codes are in the user manual. (They are in my R3 manual, but not yours) Since it's old, it could just be the CMOS battery, usually a CR2032. It's a good thing to try first and rule it out - it needs changing anyway. The Alienware standard desktop beep codes are: 1 Possible motherboard failure or the monitor is connected to wrong HDMI port on the X51 2 No RAM detected 3 Motherboard chipset failure 4 RAM read/write failure 5 Real Time Clock failure (CMOS battery) (If the monitor is connected to the onboard HDMI port when a discrete video card is installed, the X51 will produce the 5 beeps) 6 Video card failure 7 Processor Failure

February 26, 2016 - My Alienware x51 R3 is beeping consecutively twice and my monitor isn't getting input (stays in power saving mode), and not a single damn Dell article has helped me understand why. Either they aren't very specific, or they give me a link that I can't view on my phone.

I finally got it to work. It was a simple mistake. It turns out that the RAM stick was facing the wrong way. I didnt understand because all the videos I watched about uprgrading the RAM on the x51 had the sticker side facing away from the fan. I'm terribly sorry for freaking out when it was a simple solution.
