John, When you quoted and corrected me in your last post, you conveniently left this part of the quote off "Carl is more knowledgeable about this, so it might be better to ask him." How come? Scumbria

<A system using more than three or four DDR266 DIMMs will almost certainly need to use registered devices, whereas such a system may be possible with conventional PC133 DIMMs. In this situation, the registered DDR266 memory will have a longer latency and according to you will therefore have worse performance than PC133. > Jerking again, John Walliker? Comparing apples with bananas? "Almost certainly" against "may be possible", huh? If a system has to have a very large memory, it will use registered devices, DDR or SDRAM. Therefore please do not do tricks and compare apples-to-apples. In addition, shorter data phase for DDR also impies that _subsequent_ latency become smaller, for further performance benefits. BTW, "very large memory" automatically implies that your DRDRAM is out of league here :) :) Is that what you meant when trying to ridicule Scumbria's "question"?

Hi John Walliker; Re: "In this situation, the registered DDR266 memory will have a longer latency and according to you will therefore have worse performance than PC133." You're getting dangerously off message (but possibly accurate) here. Remember that Rambus bulls are supposed to believe that bandwidth is more important than latency, so even registered DDR266 is supposed to be faster than unregistered PC133. Otherwise, you could end up explaining why PC133 beats PC800, and we wouldn't want that now, would we. In most systems, running only very rare memory usage, I would think that a registered DDR266 would be at best comparable to a PC133, and likely slower. But PC800 is also at best comparable and likely slower, while unregistered DDR266 will beat both PC800 and PC133. -- Carl
