Smart SDR restarts on its own in Win7

KD4Y

Having a issue with SSDR Ver 1.3.8 rebooting computer out of the blue!
I'm using Win7 64. The Video card is an Nvidia Ti 650 boost. No problems
using Power SDR with my 3000.

Are you getting a blue screen of death with an error message pointing to the Nvida driver?  I'm fighting a similar problem with my Nvidia 650, but I'm pretty sure I've seen it happen at least once,even when I didn't have SSDR running.

No Blue Screen with mine, Just the Computer restarts on its own while SSDR is running.

Have had the same problem with 1.3.8 in Win 7 64 bit. Have also had difficulty getting panadapter and waterfall to properly sync. Often had a 3 to 5 or more second delay - a real aggravation, considering the 6500's pricetag. Finally went back to the previous SSDR version.

Recently we have been getting reports of several NVIDIA graphics cards having problems with rendering the high resolution display, not the display lagging issue, which is a known and acknowledged defect we are working on.  

Always make sure that you are using the most recent non-beta video drivers.  The WHQL driver might be in order.   Historically, we have see very different levels of performance between NVIDIA driver version.  One versions works well and the next doesn't.

thanks Tim latest Non Beta Driver is loaded. i have been running the computer for the last 48 hrs with out a restart. Miss my 6500!

If the PC is crashing without ant errors, this indicates the a hardware driver that is running in protected memory has crashed.  Since SmartSDR runs in user mode, there is no way it can crash the PC without throwing some sort of error.  So the root cause of this is a driver / hardware issue.  

A quick Google search has reports of the GTX 650 TI crashing like this with other applications.  It is possible that this is an over-clocking, a thermal  or TDR  (Timeout Detection and Recovery) problem.  If you are over-clocking your PC or GPU, you should try backing off those settings.

This is a good read on thermal issues (https://forums.geforce.com/default/topic/619136/convincing-solution-found-for-tdr-crashes-black-scre...)

For TDR issues, you can change the timeout value in the Registry.  Here is an NVIDIA forum article on it. (https://forums.geforce.com/default/topic/503962/tdr-fix-here-for-nvidia-driver-crashing-randomly-in-...)

I have not over clocked the CPU  (2600K, Asus Board) or 650ti. I had the same issue with the 7700 series AMD Video Card, that's why i changed to the Nvidia. Checking Event Viewer, I see no errors??

Thanks for that tip, Tim.  I just went in an turned TDR off in the Registry.  We'll see if that solves my problem, which has existed well before 1.3.8.

Hmmmm.  Since I turned off TDR, I've had no more BSOD driver errors, but now I've had two "Connection with the radio has been lost.  Please reconnect" messages, which I hadn't seen in a long time, and one unknown problem overnight.  When I went down to the rig this morning, SSDR was shut down and not showing even on the Taskbar, but SDR-Bridge and the two CW Skimmers were still running, as was HRD Logbook.  It took a reboot of both the radio & the PC to get things back again.

Here is an up date. The computer restarts on its own With out SSDR running.
thats good news for SSDR.

I have seen a couple of Windows 8.1 BSODs with SmartSDR 1.3.8 when closing and then choosing to quickly sleep the computer. Win 8,1 throws an IRQ_NET ndis.sys error - BUT only after using the Flex for a while and then asking the PC to sleep more or less instantly after closing SSDR.

The PC runs fine and has *never* restarted in it's own - it appears to be to do with the amount of network traffic going on and the sudden request to sleep the PC.

Will try and get a DMP if I can I had that turned off as I never normally need them, never had a graphics issue and I run some old Nvidia 9500 card as that has never let me down.

NDIS.SYS which is crashing is the Windows level network driver.  I recommend updating your network hardware drivers to the latest version and making sure that the network interface you are using to communicate with the radio is not allowed to power down when in power saving modes.  It is also recommended that you change your Windows Power Options to High Performance and never put the PC to sleep or hibernation.
