Ram 10600 vs 12800 compatibility

[bennyxc]

Hello,

I just got a new Dell OptiPlex 990 mini tower and want to double-check that this new ram I found is compatible.

Current Installed RAM: 2GB,Non-ECC,1333MHz DDR3,2x1GB,Dell OptiPlex 990

Looking at: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231416&Tpk=N82E16820231416

Do I need to get the 10666 RAM in order to be compatible? or will the 12800 work as well? I'm asking before I have the GSKILL on hand

It should work, itll run at the lower speed. But you could save money and just get 1333 like this. http://www.newegg.com/Product/Product.aspx?Item=N82E16820231426 And dell most likely locked the bios so you cant change anything.

What do you want to do with the computer? If it's an HTPC, it will do just fine with the 2GB of RAM it was sold with. Those RAM deals are great, but I don't think they'll have a noticeable performance improvement for most tasks.

The computer is going to be used for large numerical simulations so I'll definitely need lots of RAM to store the arrays. Also going to be using Virtual Box to install (possibly concurrently) several different OS's for testing. Thanks for the heads up though.

Have you had a chance to check if your RAM setting are unlocked in your bios? If so, the ones you linked are faster for only $5 more. But your computer should automatically use the faster settings for the faster RAM anyways.
