Well, I stumbled upon a little combo to allow me to nearly hit my goal. Disabling the Module Bay got me down to spikes of just over 200us. However, enabling the Module Bay and then using the taskbar option to "Safely Remove Hardware" on the DVD got my average under 100us with the same few 200+ spikes.
Top latency tweaks so far:
Disable the Sigmatel audio card via Windows Device Manager
Disable Wireless via the hardware switch
Remove DVD via Safely Remove Hardware (can leave the DVD unit docked)
Grab DPC Latency 1.1.0 if you don't have that version by the way. The graphical tracking is much better than the old version.
I'm running an Inspiron with a Profire 610 and was having similar DPC issues. I managed to solve my problem by moving to an expresscard firewire option with a Texas Instrument chipset. I suggest you might want to try adding a USB PC Card to isolate the USB communications to your soundcard from the onboard system bus.
Not sure if you are running virtual instruments or not - if so, you should definitely run these off a secondary external USB hard drive (forgive me if you are already doing this - some people aren't aware of the performance issues of running these off a primary). If you are also running and recording audio, a 3rd external drive is the way to go.

Hi Argyx,

I suggest you might want to try adding a USB PC Card to isolate the USB communications to your soundcard from the onboard system bus.

Good luck,
