I think there are some fundamental issues with the IRQ allocation on this and the previous motherboard...
If the CPU has to interpret in software which of 3 devices is sending an interrupt request ie graphics car, Audigy 2 or Disk Controller then you are gonna get some pretty nasty pauses in a game when its displaying graphics, sound and paging to the HDD at the same time...
My System has Irq's 3,4,7,10,11,16 & 17 free and not in use, yet I am subjected, by this motherboard, to the following IRQ sharing which I cannot change..
0 : System timer
1 : Standard 101/102-Key or Microsoft Natural PS/2 Keyboard
6 : Standard floppy disk controller
8 : System CMOS/real time clock
9 : Microsoft ACPI-Compliant System
9 : SCSI/RAID Host Controller
12 : Microsoft PS/2 Mouse
13 : Numeric data processor
14 : Primary IDE Channel
15 : Secondary IDE Channel
18 : Intel(R) PRO/1000 MT Desktop Adapter
18 : Radeon X1900 CrossFire Edition
19 : Creative SB Audigy 2 ZS (WDM)
19 : Radeon X1900 Series
19 : Standard Dual Channel PCI IDE Controller
20 : OHCI Compliant IEEE 1394 Host Controller
21 : Marvell Yukon 88E8001/8003/8010 PCI Gigabit Ethernet Controller
And thats with USB disabled... If I enable USB then 18 and 19 each get another device allocated as well as 2 other irq's...
Its no wonder my system crashes with anything plugged into the USB...
It may be allowable to share IRQ's but I cannot think its good practice to have that level of sharing on high performance hardware...
On My Intel/gigabyte system I didnt have any sharing!
Perhaps I should have stuck with an intel/gigabyte system at least then I could play NFSMW with a decent force feedback wheel
