Hi there, I am a novice builder and was wondering what the difference was between ddr2 6400 (which I use) and ddr2 8500 and is dual channel really that much better than single.
I ran a crucial memory scan and it said that my Gigabyte P35 - DS3L motherboard could take both I googled the question and all I got was a load of tech so I thought maybe you guys could explain it better in plain english.
I did build my own system but I still have a lot to learn :thumbsup:

PC6400 is 800MHz memory.
PC8500 is 1066MHz memory.

Going to PC8500 will give you a tiny performance increase but not worth buying new memory for from my expierence.
I also didn't notice any big difference between single channel & dual channel .

Others may have had better results though.

There are speed differences between DDR2-800 and DDR2-1066, but they are, hardware wise, the same thing. Note that 1066MHz will downclock itself to 800MHz if necessary but 800MHz will not overclock to 1066MHz. DDR2 memory can have twice the data rate as standard DDR and speed increases with matched pairs. There is a speed increase with dual channel, but it is largely insignificant unless there is a large amount of data in use.

actually, if you know what you are doing, you can overclock some ddr2 800 memory to 1066. only certain brands/models can do this, and I would not recomend it however. Not only is it hard on equipment, if the memory is designed to run at 800 mhz, chances are to up the speed you will have to loosen the timings-which in my mind defeats the purpose of the overclock, tighter timings to me is almost as important as memory clock speed.

well, overclocking RAM will also make it heat up more, and i've heard its pretty delicate compared to CPU and GPU overclocking. Not worth it really.


Also, keep in mind if you have a 800mhz and a 1066mhz stick, the 1066 will downclock to match the 800mhz.
