Has anyone experienced any performance related issues after applying the hotfix?
My application utilizes the NI4461 and NI6601 boards using syncronized timing to read 2 Analog Inputs and 1 Counter input. Sample rate is 204800 (tried 98304, min. allowed for app), with block read size configured for either 60 updates per second to 100 updates per second. The applcation "used" to work flawlessly prior to VS2010. However, now I get buffer overun faults. I have a monitor on the buffer level (configured to 8 seconds worth of buffering) and buffer levels on both any input device never approaches anything near maximum. There is only typ. 100-300 samples available to read when the overrun occurs. This issue never occured until migration to VS2010 (which required the hotfix).
Any feedback would be appreciated.
Thank You

Hey Abe,
What version of DAQmx are you currently using? What version were you using before you migrated to VS2010?

Currently using 9.2.3 with Hotfix applied. Prior version is 8.8.

Hey Abe,
Have you tried DAQmx 9.2.3 with Visual Studio 2008 without installing the patch? If so, have you seen the same performance issues there? It sounds like your issue may be unrelated to the patch itself, and may be an issue with migrating from DAQmx 8.8 to 9.2.3. Would you mind creating a new Discussion Forum thread for this issue?

I've just experienced the BSOD issue, using VS 2010 and NI-DAQmx 9.2.3. Does NI-DAQmx 9.3 contain this fix? Or do I have to install the Core driver 2.65 after NI-DAQmx 9.3? No where in the readme file does it mention anything related.

Hi univater,
Yes, DAQmx 9.3 does contain the version of NI Core Drivers that resolves this issue. You do not need to install the Core Driver Updates 2.6.5 after installing DAQmx 9.3

Hello
I'd like to know if anyone tried the last NI driver ( 9.4.0 ) with VS 2010 and .Net 4
By now we are stick to .Net 2.0 acquisition application with driver 9.2.3, and a remoting connection to other applications on .Net 4
We would like to upgrade to .Net 4.0, but we cannot risk problems with our customers.
So if anyone has any news or working installations, please let me know.
Best Regards

Have not tried NI-DAQmx 9.4. But 9.3 works fine with VS 2010. Using X-series cards and Compact DAQ chassis as well. The apps are targeting .net 4.0 and also have remoting between them (primary local control & data acquisition console and a remote console).

NI-DAQmx 9.3 and later contain the fix that was applied in the lower-level core driver component.
