Trying to install 4x4GB (but wont work) 2x4GB works fine.

[soul.eater.1032]

So I've been trying to install 4x4gb ram for a while now. So far from what I've Googled, there shouldnt be a problem with my specs.

Computer runs perfectly fine with 2x4gb.

When I install 4x4gb the computer turns on, but the monitor,keyboard and mouse arent "recognized" aka not responding, cant access Boot either.

The board may have a defect. Have you ever had all 4 sticks installed before and working?
Have you tried all 4 sticks in pairs to be sure there's not a bad stick?
What happens when you install just 2 sticks in DIMM1 and DIMM3?

Corsair as well as other memory manufacturers don't guarantee using multiple memory kits will be compatible together. As the old memory has never been tested with the new memory, you will be the first to try without any guarantees.

Memory is guaranteed in the form sold. Using a single kit is recommended.
