Hi KZNerd; Re Dell's broke 700MHz machines. I feel so out of the loop. Where did you hear that?

I guess what I am expecting is that they are going to run the 800 MHz RDRAM chips at a lower frequency. Maybe Dell had -700s that didn't work at that speed.

I'm pretty sure that they are going to have to add timing margin to the system, and the only way they can do that is to derate the frequencies. But share with me some info. The thing I really want to know is whether the problem shows up as a read, a write, or a refresh kind of problem.

(Refresh problems mean that a memory bit goes bad in between read cycles. Write means that the bit always reads back bad, after once being written badly. Read means that the bit reads back with various values. I assume that they don't have a control problem, cause that would imply that using ECC wouldn't help - too many bad bits to correct.)
