Barry,

You're right. I misremembered... Ben Myers

I think that's incorrect.

No Rambus chipsets support an 800MHz FSB. The fastest FSB supported was
533MHz. All all of the machines using Rambus memory supported a 400MHz
FSB. It was the 533MHz FSB that required the 850e chipset, which only
the 8250 had. However, although the 8250 had the 850e, I don't believe
that Dell officially supported the 533MHz FSB.

IMPORTANT: Note the distinction between memory speed and FSB. With
RDRAM, you use 800 MHz memory (PC800) for a 400MHz FSB, and you use
PC1066 (1066MHz) memory for a 533MHz FSB.

Prescott was a much later CPU than any of the RDRAM chipsets, and I
don't believe that any of them supported Prescott. The issues, however,
go way beyond (and may not even include) the FSB speed. The only CPUs
officially supported by the RDRAM chipsets were Northwood and
Willamette, and the fastest officially supported CPU was the 3.06GHz
Northwood with a 533MHz FSB and Hyper-Threading.

Right. Of the Dimension RAMBUS machines, only the 8250 handles an 800MHz FSB.
It uses the latest greatest and very last Intel chipset that supports RAMBUS.

does anyone know if i can use a prescott processor on a dimession
8200?. It has a 2.0ghz cpu now , it think it is a 533MHz now. Thanks


No sir. Prescott is an 800MHz FSB CPU and so I don't imagine it would work
for that reason and possibly others:
