I'm using BIOS version PIKT36aUK on this mobo (the latest) and there are a few options in it that puzzle me... but the one that does the most is "PCI Parity". Options are 'enabled' and 'disabled'. I've no idea what this is... was kinda hoping someone had some sort of idea what it means and whether I should have it enabled or disabled. I dont notice any performance gain with it on or off... Thanks in advance.
