Pc wont boot with 16GB Ram update

[Justintime804]

I have a pc that was built for e a few years ago with 8gb of ram.

well now I'm trying to upgrade to 16gb....I bought the same brand and type of ram and now I'm trying to run 4x4gb stick and the PC wont boot with all four installed.

I'm new to this pc world so id there something else I need to do to make it load?

and yes ive made sure it was snapped in correctly.

Motherboard EVGA H55
Ram is G.Skill Sniper 4x4Gb sticks

For that board you need RAMs with low density chips.
Hard to find compatible kits, as manufacturers (like GSkill) started using high density chips.
