RAM compatibility & RAM downclock ?

[xhanne0]

Hey guys so here's the deal I have 2x 2gb RAM sticks and 1x 4GB Ram stick I found out a while ago and I decided that I would do a 3D Mark 11 test wich is here : http://www.3dmark.com/3dm11/9940721 If you scroll down you can see there that is says 800Mhz on the Team Grop Inc even do That stick is 1600 Mhz is this a question about a RAM downclock or what is going on I was planning on replacing the 2x 2gb sticks but I do not want the Team group to be 800MHz is this about compatibility or something else because what I would like, would be to have 2x 4GB Team group inc 1600Mhz here is a link to the RAM that I have (Team group) ( sorry for swedish website) http://www.kjell.com/sortiment/dator- kringutrustning/datorkomponenter/ram-minnen/ddr3-pc12800-4-gb-p93670 My SPECS ARE

If you mix different RAM modules it will underclock to the lowest denominator. i.e. the slower RAM. You need to buy matching kits when upgrading RAM to ensure full potential.

So this is not something about Compatibility ? It's just about a downclock then ? Ok but can you help me see if my motherboard is compatible with this RAM ? I can't find anything

I forgot to mention that if you only have one stick in a dual channel slot it will run in single channel, which is why it is downclocking the others to 800Mhz - Read the bottom of the PDF here.
