How much - Page 2

post #11 of 13
I am not sure what Dk MZ is getting at. Another 4 gigs will help your OS a whole lot and their shouldn't be any trouble running them on your board. Having two sets of dual channel only hampers overclocking when you are memory bandwidth limited. You are more likely to get a higher memory overclock on two sticks then four because it decreases the chances of any one of those two sticks being a dud (or poor overclocker). Remeber, all the sticks have to run at the same timings and frequencies, so if you have three really good sticks, and one just OK stick, then that can be a problem for you OC. If you don't even need 800mhz to run your setup then just get another DDR2 800 kit. It really won't be a problem, and vista will love you kindly for it.

I figured it could possibly hurt the overclock. I just didn't see why it would have problems running in Dual channel(being different sizes I could understand though.) I read about someone else doing it and figured it could be done.

Another question:

I know that RAM only runs at half the listed mhz.(DDR2-800 is clocked at 400mhz) Does that mean that when overclocking it, it brings up the 800 as well?(Since it's being doubled?) Like...

If you bring the mhz up to 425, would that make it 425x2=850? Sorry for the newbie question. I just hear people speaking of a 1:1 ratio, and I read a review were someone said he couldn't seem to get the RAM to want to operate above 1000mhz, It seemed to me that he had gotten it to be 500*2.

Is this the correct assumption?

I am not familiar with AMD boards and the way they use bandwidth, but on a intel board the opposite it true. Each stick runs at 800mhz, together they equal 1600mhz. That becomes the bus speed on intel boards, which is equal to four times the multiplier, or twice the memory bandwidth (in dual channel). The person in question was either talking about DDR memory, or just one sticks speed. AMD CPU tend to have really high multipliers, so it is not neccessary to run the RAM at a faster speed, except to increase bandwidth. There should be an option to unlink them in your bios and take full advantage.
