I'd like to report that an MSI 790FX-GD70 Motherboard with an AMD Phenom II X4 965 processor works wonderfully at a 192kHz sample rate when using a SIIG 3-Port FireWire 800 PCIe Card Model NN-E38012-S3 Firewire card. Very low DPC latency at 200us. Processor maxes out with about 20%-25% CPU used as reported in Power SDR under Windows 7.
-----Original Message----- Just to reiterate, an AMD-based system has an order of magnitude chance of success than an Intel-based system. A simply-configured motherboard has less competition for IRQs. _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/
