RAM Upgrading

My Dell computer is using a Dell motherboard (who would have guessed?) and I'm confused if I can go to a higher RAM speed or not than what is listed in CPU-Z. Max Bandwidth: PC3-8500F (533 MHz), I want to upgrade to a 12GB (6x2GB) bundle and I'm not sure if using DDR3 10600 instead of my current 1066 will cause issues. Also, I'm curious if CAS latency and voltage make a difference when it comes to installing. Newegg only offers 6GB (3x2GB) bundles which is fine, I'll buy two because I want to fill my memory slots up and take advantage of triple-channel since my motherboard supports that.

1066 6GB (3x2GB) module list

10600 6GB (3x2GB) module list

There higher speed is $10 more which I don't understand either probably because the slower speed is much older.

Ideal RAM

If my motherboard supports this speed then I would like to go with this option since it would $100 which is cheaper than anything in the other section.

Yes you can go to a higher memory speed but the computer will run them as the highest they.

Also 9 or 7 cas doesn't make any difference unless you look at benchmarks.
And a lower voltage will make then draw less power and be more stable.

i have 1600Mhz dimms in my system running at 1333.

Thank you. I wonder what my PC would run the 10600 RAM at then?

fairly near the stock dimms speeds I'm guessing.

If you plan on getting that much RAM please be aware that if your operating system isn't 64 bit then it'll only utilize a maximum of 3.5 GB of the input RAM resulting in any additional memory being wasted, if your computer is new then the odds that the operating system is x64 instead of an x84 (32 bit) are high otherwise, if your OS IS 32 bit then no point getting more than 3.5 because it'll just be a waste. xD
