ram

We are currently designing our new database servers, and have come up with a trade off I'm not entirely sure of how to answer.

These are our options: 48GB 1333MHz, or 96GB 1066MHz.

My thinking is that RAM should be plentiful for a Database Server (we have plenty and plenty of data, and some very large queries) rather than as quick as it could be. Apparently we can't get 16GB chips at 1333MHz, hence the choices above.

So, should we get lots of slower RAM, or less faster RAM?

Extra Info:

Number of DIMM Slots Available: 6
Servers: Dell Blades CPU: 6 core (only single socket due to Oracle licensing).
