Re: Hyper-Threading and Reduced Performance

Tech-Archive recommends: Speed Up your PC by fixing your registry

I don't know if this is anything, but I found on the Soundblaster site that
someone stated you should put your soundcard into PCI Slot #3 (on an intel
board) so it is assigned is own IRQ, because if not, it may interfere with a
hyperthreading processor if it is sharing its IRQ.

Right now, mine is in slot #5, and it shares its IRQ with 3 other devices.

Any thoughts on this before I tear apart my computer yet again?

I suppose it's worth a try. Moving the card will change the IRQ that it
uses, tho WHICH IRQ is most likely mobo dependent. You may need to move
it a couple of times to see which one it switches to.

And yes, it does make sense - interrupts would be the most likely cause of
a timing related bug actually cropping up.

Moving the card should be fairly easy, BUT...

Recently, I put an X-FI card in, and my second video stopped working; I
moved the card to a different slot and it was unrecognized! I had to
completely reinstall the creative drivers to make it see the card again -
I'd never encountered that before, usually the system/driver/PnP just
notices the move and adjusts itself, w/o requiring a complete reinstall.
[plus it didn't resolve the issue - turned out I had to enlarge the AGP
Apature to fix the issue; took several days of googling to find the
soulution, but someone out there had the problem too and had posted
about it. The answers ARE out there...!].

BTW, my X-Fi is currently sitting on IRQ 20, all by itself.
