Why are 512mb RAM chips standard?

[jac0b84]

I am curious why the 2x512 combination of ram is more common. I am looking into upgrading RAM, i have 4 dimms and 4 GB max ram. I would like to put in 2x102 ocz platinum but the timings on the rev 2 512 chips are a little better (2-3-2-5, to 2-2-2-5). Is this something that will affect an overclock or performance in general? If so, are there any 1024 chips with 2-2-2-5 timings.


Thanks

the difference between 2-2-2-5 and 2-3-2-5 isnt going to be noticeable, or affect an overclock much at all (like not even 2 seconds extra running superPI)

Same thing as maybe a year or two ago - 2x256 was cheaper than 1x512, unless you got slower timings. It's similar nowadays, 2x512 is cheaper than 1x1024.

Same reason 400 GB drives cost more per GB than 160, and A64 4000+ costs more per "100+" than an A64 3000+.

The highest-end parts are lower yield (more expensive to make) and sell to a smaller part of the market that is willing to pay a premium for the best performance.

will having 2 different types of ram affect an overclock. to me it seems like the weakest link in the chain determines the strength.
