I'm in dispute with Dell. They offered, and I ordered, a Pentium D 3.0

hyperthreading.

They claim that MCC (multipe core capability), which the system has,
is better than hyperthreading.

My experience is that I can get 20+ SETI WUs a day with SetiDriver set
to 2 processes. If I set SetiDriver to 4 processes I get about 18 a
day.

Should I expect to get more than 20+ a day with hyperthreading?


I thought that HT was disabled on the Pentium Ds? IIRC only the XEON Ds will
have HT enabled.

I could be wrong...
It looks like Dell (France) screwed up when they offered me "Dimension
9100 biproces. Pentium D.830 avec [with] Hyper Threading". The only
dual processor with HT I can find on the Intel site is the Extreme
Edition, and Dell don't appear to offer it.

I guess my only choices are:

1. Accept what I have
2. Return it, and wait for something better...
