128MB vs 256MB and signal noise

[Bonehead]

Does anyone know if a 256MB stick creates more signal noise wich will effect its max-out overclocking potential in compared to a 128MB stick rated for the same speed (both double-sided)?

For example: I can choose between 128MB PC160 and 256MB PC160, all rated for 160Mhz but if I want to get the max out of it (maybe 170-180), will I make a better chance buying the 128MB stick?

IMHO- 256MB of RAM running at a slightly lower clock speed would still be favorable than 128MB at slightly higher.

Anyone agree?

Yes 256MB is favorable over 128MB but I want to know if there is a rule that higher capacity sticks produce more signal noise and affect overclocking more than a 128MB stick in getting it to extreme busspeeds.

doubling your ram versus a few fsb MHz of increase....
hmmm, i think I go with the others and saygo with the extra RAM.

I have noticed no OCing differences when I have upgraded or added RAM.

In CMOS circuits, attaching more inputs to one output results in slower switching times. This is why some modules that use a lot of chips need to be used with relaxed memory timings. But this really shouldn't be a problem if the motherboard and the memory are of decent quality. I've only hear of really chip-laden modules being affected. I don't think a 16 chip module will put that much of a strain on a board.

If I had the choice of 256MB of cas3 memory vs 128MB of cas2 memory, I would pick 256MB of cas3 memory any day! Otherwise I'd be swapping to disk more often. Using the disk for memory is FAR, FAR slower than even the slowest DRAMS.
