Default new cruncher@work

My new cruncer arrived at work. It's a Dell T3500 with E5630 processor, which is basically a Xeon version of an i7 LGA1366 processor. Benchmarks to follow.

I have several questions about its setup (for maximum Boinc performance ). These are settings in BIOS. I would appreciate if someone could tell me if the setting is best on, off, or doesn't matter.

1. Hyperthreading. It's my first ever HT capable CPU. I completely missed out on the previous P4 HT wave. I turned HT off. I gather that 8 processes divided over 4 cores creates more overhead than 4.

2. Speedstep. Now off.

3. Turbo boost. It's now on, but I wonder if that's useful with 4 cores working at 100%

Hyperthreading gaat niet sneller crunchen maar kan voordeel hebben om meer taken te krijgen (vb SIMAP = 30 tasks per core)
Turboboost heeft inderdaad geen nut zolang je 4 cores op 100% zitten, maar als ik me niet vergis kan het geen kwaad om het aan te zetten. Op het moment dat er één of meer cores zonder vallen gaan die andere iets rapper werken.
Ik wou dat ze bij ons ook zo vrijgevig waren bij het uitdelen van PC's.
Wij mogen trouwens geen software installeren op onze PC's die niet aangekocht is door de werkgever
