ULi M1575 for ATI Crossfire – SATA2 and Fast USB for the ATI Chipset

The ULi M1575 South Bridge
The earlier ULi M1573 South Bridge had a feature set roughly comparable to the ATI SB450 South Bridge described in the Crossfire AMD launch article. The only real difference is that M1573 does support NCQ on hard drives while the ATI RS450 does not. M1575 updates M1573 for a much more competitive feature set.
The M1575 feature set is very competitive except for the fact that it only supports 10/100 Ethernet. However, PCIe Gigabit Ethernet can be added to PCIe lanes on the South Bridge or North Bridge to provide a dual Gigabit PCIe/10-100 PCI LAN solution.

- 4-Drive Serial ATA II 3Gb/s (AHCI) with NCQ Support
- RAID 1, 0, 0+1, 5, JBOD
- PCI Express Interface to North Bridge (Like SB450 and M1575)
- High Definition Audio and AC'97 Audio
- Full ACPI and Legacy Interrupt/DMA support

Nice , no active cooling chipset fans to burn out in days after purchase.formulav8 - Thursday, October 13, 2005 - link
Could it really be as simple as the Codec for causing higher cpu usage compared to other codecs or does the audio's hardware have more of a impact? I may go do some research on this.Jason

We have seen very large variations in Azalia HD Audio CPU utilization depending on the driver version used with the codec. That's why we suggested, in the article, that ULi, Realtek, or whichever codec is used for HD audio, may need to do more optimization of the HD Audio drivers.formulav8 - Thursday, October 13, 2005 - link
I don't see why these companys cannot put decent non cpu hogging audio in their south bridge.They do look to have good disk performance though.

I knew there was a reason I keep using my Creative Sound blaster Audigy 2 sound card ;)
