I am running PSDR 2.7.2 under Windows 7 on a Quad-Core 3.7 GHz Dell system with 12 GB of RAM. I've taken the following measures and find that PSDR is usually rock solid:
* All my drivers are up to date including that for the NVidia GT-530 card. * Besides the basic video driver, NVidia has two additional processes (3D and End user experience) it likes to run. I disable them with no ill effects. * I have found it advisable to turn off Norton 360 but make sure to restart it when PSDR has closed. A friend of mine left his off for a week and wound up with the Crypto Locker virus. * Carbonite and other cloud based back-up programs can really tear up Power SDR. I turn them off. * I've also found it advisable to disable the DX Cluster feature of HRD unless I really need it. I have not found that the basic call sign lookup to QRZ causes much disruption. My typical CPU utilization runs between .75 and 6%. I have found that LatencyMon from Resplendence (the free version) is a good tool (in addition to the Flex Radio fire wire driver software) for diagnosing causes of system latency/PSDR audio drop outs as it shows the particular device or program causing spikes. 73 Bill Roberts- K8DXX _______________________________________________ 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.flexradio.com/ Homepage: http://www.flexradio.com/
