Does one have to use two sticks of this stuff for it to work? I have one, and don't want to buy another, so I hope not.

That should be a matched pair. But since i850 has two banks (each bank has two slots), two banks can have dissimilar sizes.Yep, you have to use a pair like ihrjin said but I have a question also, can use two modules that are different sizes??

RDRAM is 16 bitDavid said:
I'm not sure if RDRAM works like SIMMs or not:
SIMMs had a memory bus of 64bits, but each stick made up 32bits, so two sticks were needed.
I think RDRAM may be the same but 2*64 to give 128.
Yeah, the i850 chipset uses DUAL channel RDRAM, so far there is no way around it.Does one have to use two sticks of this stuff for it to work? I have one, and don't want to buy another, so I hope not.
Yes The i850 chipset also requires two CRIMMs if the slots are not being used. As far as I know, you need One pair of sticks per channel and a maximum of two channels are available. If the second channel is not used CRIMMs are totally nesscessary.DaddyB said:yeah you need 2 sticks for the i850 chipset because, as will said, it is dual channel but I think the older RDRAM chipset only needed one stick (i think it was the i840 chipset). RDRAM's latency is higher then ddr sdram and the idea of using dual channel RDRAM was to lower the latency and make rdram more competetive with ddr sdram. so even if you could use only one stick I think you would see a large performance drop.
on a side note my dell came with 2 continuity modules for the 2 RDRAM slots that aren't being used...why, i dont know.
The board has the 820 chipset, does anyone know about that one? Its a Dual P3. Thanks
