Re: [Flexradio] Flex freezing
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/
[Flexradio] Flex freezing
Craig I have a 1500 and it is running XP on an old Dell 530S, my cpu utilization is between 15-20%. I too, had freezing last year, and after a few months of freezing and blue screens…I found that the constant updates of the AVG web security and various background programs waking up or updating in the background was causing both the blue screens as well as the SDR freezes. I Used the OS hardening papers that Neal points to in the Flex forums to shutdown, stop or simply remove ANY programs not needed to support my Flex 1500….it has been running freeze free since last December and blue screen free since last October, knock on wood. Sadly, I am going to have to face the music and build a Win7 machine, since support for XP and likely SDR on XP will soon be going away. best of luck, but my bet is on something annoying Windows/CPU dave dabay kd...@twlakes.net ___ 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/
Re: [Flexradio] Flex freezing
Very periodic, can't put a finger on WHY or WHAT CAUSES IT, but it will be visible on my desktop, but frozen. Requires a closing by X and restart.

I think it may be something in the drivers for PSDR. NaP3, which is a version of PSDR that does not use the Flex drivers, never freezes on Win 7 even on a machine with many cloud-based interrupts going on all the time. But if you wish to use the Flex version, it seems that the way to avoid this headache is to cut the machine off from other activity, as Neal suggests. My wild guess is that some ring buffer gets hosed, data comes in but has nowhere to go, and the operating system goes into a permanent wait state or maybe part of its memory gets clobbered. Whatever it is, making the machine single-purpose seems to solve the dilemma. Good luck!
