RAM of that speed will be DDR2.  Desktop DDR2 modules have a 240pin connection.  Original DDR modules have a 184pin connection.  The 'key' is also in a slightly different position, preventing you from inserting a DDR2 module into a DDR motherboard, or vice versa.  Have a look here for some side by side comparisons - http://www.auscomtech.com.au/Products/ddr%20v%20ddr2.htm

 

DDR stands for double data rate (transfers data on both the rise and fall of the clock signal), so a speed of DDR 800 is just telling you that it's 400mhz RAM that has an effective data rate of 800mhz.  While DDR, DDR2, DDR3 etc. are different standards.

 

I don't like the fact they are selling it as DDR667/800.  It's one or the other surely?  Perhaps they mean it's 800mhz memory that can be used at 667mhz.  I prefer getting from a known brand like Corsair, Kingston or Crucial.  It's very slightly more expensive but bad RAM can cause big problems.  And they aren't always immediately obvious.
