Ten,

I don't think this was a technical problem. I don't see any technical issues regarding heat or power that would be expensive or difficult ot overcome. After all, Intel solved these problems easily for the i840.

As I remember, after the 820 recall, Intel sent prototype i820s to the MOBO manufacturers that ran about 1.5 X the speed of the final production i820s. There was a lot of talk about about de-rating at the time.

Makes you wonder why Tom's and Anand aren't overclocking the I820.

This sounds like a simple marketing decision to de-rate the product so as to minimize cannibalization from the WS business.

Tenchusatsu,

I doubt it. I think if Intel could have licked the problems with just a beefier power supply or better airflow, they would have.

In that case, I really don't understand what is going on. The only place I can think of where the power dissipation could depend on the number of active banks is in the memory chips/modules themselves. The same memory is used in the 820 as in the 840, so why the difference?

John
