Supposedly nVidia's Geforce cards all suffer from the same problem ranging from the original to the Geforce 3, in that they all have memory bandwidth problems. Correct me if this is not right. No one overclocks the core of the card because it would do little, but the ram on the other had will do a lot. If you could double the ram's speed say from 500mhz to 1ghz, would that double performance? If so, why do manufacturers/nVidia do this. Instead of equipping cards with 64meg of ram at say DDR 250mhz, which usually at that amount is pretty overkill, why not run 2 sets of 32meg of ram at 250mhz, which equals 500mhz, which due to the fact that its DDR yields 1ghz??????? Is that a correct assumtion? Can that be done? I vaguely remember reading something awhile back about motherboards offering double the ram bandwidth, but you half the amount of ram. Im guessing that this technique cannot be done for some reason, otherwise some rouge manufacturer would put out a super duper geforce 3 that is twice as fast as anything out there. Any comments on this? What is limiting manufacturers from doing this right now? Thanks!
