Scumbria,

How does the latency of standard PC133 DIMMs compare with registered DDR266 DIMMs?
I believe that DDR266 is planned to come with CAS latency 2, 2.5, and 3. PC133 has CAS latency 2 or 3.
So the latency should be identical.


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.
