It's been running extremely well for me over the past couple of days. I had been using a Fujitsu-Siemens D1219 mobo with a 1GHz PIII. I had been happy with that, but it's got an on-board limitation of 512MB of RAM, and I have been working on a large session which pushed it to its limits. Since I got the ASUS/P4 combo, I've not seen any xruns, not even the ones I used to see when exiting Ardour (my primary tool). Latency's not a big issue for me, as I use a Delta 1010, and use hardware monitoring. My only complaint is that the fan on the heatsink for the P4 is much louder than the one for the PIII, and my machine's noticably noisier now. (I also had to swap out a non-quiet power supply from the case I put the PIII in for my son - the P4s need an extra power connection that the old P/S didn't have. I intend to get a quieter P/S next! For what it's worth, I have jack using 256 frames/period, which gives me 11ms latency. When I first booted, my 1010 got an IRQ 5 assignment - ick!! It was easy to force it to 9 in the BIOS, but then I found it was sharing it with the ethernet controller. I checked the manual, which lists the onboard devices each PCI slot might share an IRQ with, and moved the 1010 to the next slot over, which could have shared an IRQ with the USB controller, but I'd disabled that in the BIOS (along with the serial, parallel and game ports, and the onboard audio) and now the 1010 has IRQ 9 all to itself. The beautiful thing for me was that after all the hardware swapping (I also upgraded the video card to an nVidia 5700 from an nVidia 5200), I had to change *one* driver for the LAN connection, and the system came up, just as I had left it :) Trying to boot my son's old Windows hard drive on a new Mobo... that was painful. -- ====================================================================== Joe Hartley - UNIX/network Consultant - jh(a)brainiac.com Without deviation from the norm, "progress" is not possible. - FZappa
