Lightbulb 256x4

im on my school computer and it hit me, since its a big boost in memory speed in dual channel...what about quad channel of 256....hurry and post back

First off, it's not a big boost in speed to run dual channel. It's not even a 50% increase. And it all depends on the hardware involved.

Read up on what dual-channel actually is, first.

So called "quad channel" is just four sticks of RAM set in two sets of dual channel.

there is no concept of quad channel till now.

as I am using quad banks, but performance is as same as dual channel.

Yeah, dual channel is basically a small increase in data transfer, but it benefits latency more than anything else, which translates into stability.

However, since 256MB sticks generally have lower timings and overclock overall better than larger sticks, it would probably be somewhat of an advantage over 2x512MB.

There is no concept of 'quad channel' at all, like shoobie said.

if you had 4 sticks of 256mb your computer would see it as 1gb of RAM in dual channel, that's it.

The size of the memory has no effect on the timings. It's the particular IC's used on the RAM that determines that, so although the statement 2x256 tend to OC better is true the '256mb sticks have lower timings' is not.

Dual-channel just means that the two sticks will work well together. The performance increases are often negligable at best.

Dual-channel is not going to make your RAM run twice as fast or make it seem like more RAM or anything like that. There's simply a small 5-20% speed increase, at best, because the RAM sticks communicate more easily than non-dual-channel setups.
