Alright, I read these forums all the time for help and 99% of the time someone else's question is something I'm able to go off of to fix the issue I'm having. However, for this one time it's unique issue I'm having specific to me so I hope I can get some help.
I've had my ASUS CM1630 Desktop (64-bit Windows 7) for a few years now and finally decided to upgrade the RAM.
Here are my specs from the Crucial Scan:
As you can see my computer can take 16GB total and there are four available slots)
The amount of memory that came with the computer was 4GB of Ram (two 2GB sticks - sucky I know!).
So I went to CDW and bought four 4GB sticks which totaled 16GB of RAM.
Here is where issues came into play:
I seated all the sticks correctly and the computer would seem to start running but nothing would show up. It was as if I had the monitor unplugged (but it wasn't). I literally mean I couldn't see ANYTHING (no bios no boot up no nothing). Everything was running fine (fans, lights, etc).
So I took two sticks out and left the remaining two. This worked for a total of 8GB (showed up in the my computer screen). Everytime I tried to insert a 3rd or 4th stick I would get the nothing showing on the screen issue.
To see if I had an issue with the RAM or with the slots I swapped the two sticks of RAM that were working in my computer with the two sticks of RAM that were not working in the other slots. Presto, this worked.
So I've now come to the conclusion that two of my RAM slots are dead and two are working.
So I figured the easiest solution next would be to return the four 4GB sticks and buy two 8GB sticks and place them in the two slots that are working which would give me the 16GB I've been looking for all along.
CDW was very nice, returned the four 4GB sticks and gave me two 8GB sticks. Came home, seated both 8GB sticks in the two working slots from before.... and I got the same original issue of nothing showing on screen (searching for signal as if I didn't have a monitor plugged in).
Then I thought to just try ONE stick of 8GB ram (since 8GB worked before with the two 4GB sticks) and this didn't even work. When I put the original two 2 GB sticks back in it works fine.
So to recap:
I want to utilize the full 16GB of RAM my computer is able to take (this has been verified).
Two of my four RAM slots don't work which means two of them do work which means my only option is two 8GB sticks.
The original two 2GB sticks that came with the computer work
Two 4GB sticks that I bought from CDW work
Two 8GB sticks that I bought from CDW don't work
One 8GB stick that I bought from CDW doesn't work
What is going on? Does anyone have any advice? The Crucial system scan I ran (link above) told me that my machine SHOULD be able to take 8GB sticks.
Any help is appreciated!
P.S. The brand of RAM CDW sold me is called "EDGE"
