I realise that most PCs can now handle unpaired memory cards but on the servers I work with (x86) they still say you must install in pairs?

Most RAM commonly available was developed for 32 bit processors. The servers you're working with are likely to be 64 bit processors, so the memory needs to be installed in "matched pairs" to allow a full 64 bit transfer. Many reccomend not just pairs put "matched pairs" to try to ensure that both RAM sticks are as close to possible to identical.

Yes unpaired is true but whether or not it has to run in pair is dependant on the hardware being used. Pentiums had 64-bit bus to enhance system speed to keep up with the 32-bit core CPU. So the reason for it is somewhat historical. But then gamers would always push for higher bus system performance.

A hang over from prehistoric computer days. It was faster to use the memory in pairs, with it alternating between the pairs for every other word of information. You double the bus speed by reading from two buses at the same time.
Now that bus speeds have increased, often the bus can deliver information faster then the processor can use it. There is no advantage to doing it any more.

you are able to set up it one after the other. once you've twin channel reminiscence help there is an advantage to setting up it in pairs and this can enhance your reminiscence bandwidth. frequently twin channel motherboards have 4 slots with 2 slots one colour and a pair of slots a 2d colour. you want to positioned a matched pair of reminiscence DIMMS into slot 0 and a pair of. Or a million and three.

Well its not that it won't work if u don't install them in pairs.
Its just for precaution that, using rams in pair enhances the performance since burden is shared beside if one burns out, the other can handle the situation.

som ram is designed to only work in pairs like rambus or rd ram

it would be better if you do it becoz if one goes wrong other can handle the situation, preventing sever crash
