Hiya, I’ve been experiencing weird problems with a s/h board & cpu I’m trying to put together: 1. The onboard audio produces a slight but still perfectly audible interference which becomes stronger whenever there is a background activity going (file transfer, web browsing, etc.). I did think of EMI, so the spread-spectrum is enabled in Bios. To no avail but this is not a big deal indeed; I am going to be using the board with a Focusrite Saffire LE 1394 audio interface anyways. However, there is more to it, apparently… 2. When not in a High Performance mode in Power Options, the audio (even a simple mp3 file) through the external sound card would pop and clip whenever there is a background activity going (file transfer, etc.). No problems at all when in a HP mode though. 3. When not in a HP mode, the system time would fall behind. This is true for the both Balanced and Power Saver modes. 4. The CPU seems to be running a little too hot. When in a HP mode it idles at 51-53, consuming 140W (per CPUID HW monitor) at all times. The cooler is adequate and the airflow in the case is excellent. I’ll be re-applying the thermal compound (Xigmatek PTI-G4512) tonight, just to be sure. Motherboard: Asus M3N-HT Deluxe CPU/cooler: Phenom II X4 940 / Arctic Freezer 13 Pro RAM: 2x2 GB Mushkin, PC8500 PSU: Seasonic SS-650HT-F3 GPU: Gigabyte GTX 550 Ti Settings/OS: W7 ultimate, 2 disks in AHCI/SATA, Bios is not the latest (3401) but the version prior to that (3302) - not too keen on flashing it just yet, as I’ve seen a whole bunch of guys on the web having problems with this board after the Bios updates (I won’t assume all of them fellas are clueless). The chipset/audio drivers are the latest ones from the ASUS web-site. Any help is greatly appreciated.
