Recently I received 2 8GB sticks -Link- , I had 4 2GB sticks and took two out to install them, (I also installed a new graphics card along with them but found out it was not the problem)

When I turned on my computer nothing happened with the motherboard (I believe, reason being the keyboard mouse and speckrs didn't work. Monitors didn't work either. no beeps ).

I found when I took out the newly installed memory that the sys was able to turn on, same thing when i took all of the other memory sticks out and just used the new ones it was able to function normally.

What I want to know is if this is a capability issue between the new and old sticks, or if this is a power issue of some kind. it might not do anything but sense i have them I would like 20GB memory instead of just 16GB although i'm fine with that because it beats the 8 I had before.

It's a compatibility issue not a power issue, unless you mean a voltage issue between the old and new RAM which would be a compatibility issue too. Mixing RAM always has the potential to cause issues.

You haven't told use what motherboard or system you have or the model number of the old RAM, that's useful information for troubleshooting.

Do you need more than 16GB of RAM?

From what I can determine, the Alienware 046MHW motherboard has 4 memory slots and supports a maximum of 16 GB(4 GB X 4) of DDR3 RAM.

Is it the Aurora R3 that you have? If so it only supports 16GB of RAM according to Dell.

The other difference I see is that the old RAM is 1333Mhz and the new RAM is 1600Mhz.

You'll likely be better off with 16GB of RAM running at 1600Mhz than 32GB running at 1333Mhz.

What's the "service tag" number and/or "express service code" number on that Alienware?

What one of these models do you have?

Here is the memory(RAM) information from its on-line manual.

It uses 1 GB, 2 GB, and 4 GB modules.
Interesting, I have two 8 GBs in right now, so i'm either wrong or i cheated the system! either way the 16 cap is what got me. thank you for the useful information
