Dual Channel Memory

  rickf 16:33 15 Jun 03

1) I have the GA-8IG1000 Pro running dual memory. At present I have two identical single sided 256 modules on banks 1 and 3. I am thinking of upping these to 1024 ddr. Would I need to get the other pair to be isdentical with the present pair. This, I envisage would be a problem as it may not be possible to find identical ones by then. Any ideas appreciated.
2) Dual meory basically increases the amount by 1.5 times. I have 512 at present and it is showing this in device manager. Should it not read closer to 768mb or is the 256 increase hidden.

THanks in advance.

If you have 2 x 256Mb sticks that is 512Mb
dual channel can give you an extra 3-5% performance gain.

Where did you come by the idea that it increased the size of your ram???

My mother board manual gave this example:
4g=6.4g app.
Manual of said motherboard above. Anyway, should the increase be shown in device manager. Do you know?

if you put more memory in it will be shown in device manager.darren

that example you're shown is the bandwidth that the memory transfers data to the FSB, NOT the size amount of RAM itself.

Dual channel gives you faster, not more, memory - you may be confusing a data bandwidth (speed, roughly) of 4GHz being upped tp 6.4GHz.
