i've heard that the lesser the modules the better the performance will be:

1x512 is better than 2x256 - consiering single channel
2x512 is better than 4x256 - considering dual channel

they say it's because it minimizes latency..... can you guys give me an explanation or links that i can somehow absorb this idea? preferably not so technical and not so laymen either...

thanks!
 
The memory controller has less to deal with. On AMD 64-bit platforms though, the point is pretty much moot.

And if your sane and running a real computer (that is AMD) the first line is wrong, because of dual-channel. It would only be true if said computer doesn't support dual channel.
 
It's not only with latency (for the game market that's all they seem to care about) but memory errors. As games get more complicated and more computation is needed to run them memory errors are increased, memory makers will have to do something about it. The solution now is one gamers wouldn't enjoy, as it'll take 3 to 5% off their performance -- ECC Registered memory. So the desktop market will have to live with more reboots and OS errors due to it.

The more modules increases more errors because it increases the chances of one module going bad (hardware and messing up a code string).

And another thing: another source of those memory errors isn't the memory itself, it's the PSU. Another reason to invest in a quality power supply (although Antec has improved, it has some of the worst memory interference ratios -- be it the True 480 or above).
 
well, for RAM to buy, 2x512 ValueRAM should be very stable (unless you get bad sticks, which you can RMA) , and can be had for ~$130.

I agree with you 100% about a PSU being very important to overall stability. However, I'd really like to know where you got your information about Antec, regarding interference ratios.
